Gastroscopy sedation: Sedated vs unsedated gastroscopy
Something I see often in my clinic: patients who’ve been told they need a gastroscopy, who’ve then spent three days on the internet, and who arrive with one specific question: Do I have to be sedated? It’s a reasonable thing to want clarity on. The choice of gastroscopy sedation affects your comfort, your recovery time, and sometimes the quality of what we can see. I’m Dr Prakash Gupta, a Consultant Gastroenterologist. Let me walk you through both options honestly. What a Gastroscopy Involves A gastroscopy passes a thin flexible camera through your mouth, down the oesophagus, and into the stomach and upper small intestine. It’s the most direct way to investigate persistent reflux, unexplained nausea, upper abdominal pain, or concerns about ulcers and inflammation. The procedure takes between five and fifteen minutes. The sedation question is entirely separate – it’s about how you experience those minutes, not about the diagnosis. Sedated Gastroscopy With sedation, you receive an intravenous medication – most commonly Fentanyl and Midazolam and in some cases, an anaesthetist-administered propofol – before we begin. Within a minute or two, you’re deeply relaxed or asleep. Most patients remember nothing. They wake up in recovery, someone drives them home, and the procedure feels like it never happened. This is the most common choice, and for good reason. No discomfort, no memory of gagging, no anxiety to push through. For patients who are nervous or have a strong gag reflex, sedation removes what would otherwise be a genuinely unpleasant experience. The trade-off is real, though. You need someone to take you home – no exceptions. You’ll spend around an hour in recovery. Driving, operating machinery, or making important decisions that day is off the table. Unsedated Gastroscopy Going unsedated means a local anaesthetic spray to the back of your throat, then staying fully conscious throughout. The spray numbs the gag reflex enough that most people tolerate it. Because there’s no sedation to sleep off, you can drive yourself home and return to work the same day. I won’t pretend it’s entirely comfortable. You’ll feel the tube. You may gag. It requires a degree of calm that some patients simply can’t muster – and that’s not a criticism. Anxiety is real. But plenty of patients do fine. For those who prefer to stay in control, or who can’t bring a carer, it’s a legitimate option – not a fallback. Side by Side: Sedated vs Unsedated Sedated Unsedated Comfort during procedure High – most feel nothing Moderate – some gagging likely Memory of scope Usually none Full Recovery time 1–2 hours Minimal Can drive after No Yes Need a carer Yes – mandatory No Suitable for anxious patients Yes Less ideal Risk of sedation side effects Small but present None Same-day return to work Unlikely Yes Which One Is Right for You There’s no universal answer. What I look at: How anxious are you? Do you have a strong gag reflex? Can you bring someone to drive you home? Are there medical reasons sedation carries extra risk for you specifically? Where those answers point clearly one way, the decision is straightforward. What I’d push back on is the assumption that sedation is always the more thorough option. In the right patient, an unsedated scope done well gives us everything we need. The sedation choice matters – but what matters more is having the investigation done at all. If gut symptoms have been nagging at you, don’t wait for them to get louder. At Harmony Gut and Liver, we offer gastroscopy with full sedation options, alongside a broader digestive assessment.

What Is a Gastroscopy Looking For? Conditions It Can Detect
Some symptoms just won’t let you ignore them. A burning feeling after most meals. Trouble swallowing food you’ve eaten your whole life. Nausea that shows up without warning. You get blood tests done, and everything comes back normal. And yet something still feels off. This is when many people start asking, “What Is a Gastroscopy Looking For?” because it can help doctors examine the upper digestive tract more closely. I’m Dr Prakash Gupta, Consultant Gastroenterologist. I hear this from patients regularly. Normal tests, real symptoms, no answers. And in many of those cases, what finally gave us the answer was a gastroscopy – a direct look at what’s actually going on inside.” What Is a Gastroscopy Looking For? A gastroscopy – sometimes called an upper endoscopy or OGD – passes a thin, flexible camera through the mouth to examine the oesophagus, stomach, and duodenum (the first section of the small intestine). It takes around 10 to 15 minutes. So, what is a gastroscopy looking for? The answer is: things blood tests and scans simply cannot show. The lining of your gut, changes in tissue, signs of infection, early damage – all of it visible in real time. Conditions It Can Detect Acid Reflux and GORD: Heartburn is the most common reason patients come to me for an upper GI review. A gastroscopy tells us whether your oesophagus lining has actually been damaged – and how badly. Symptoms alone can’t give us that. Barrett’s Oesophagus: With long-term acid exposure, the oesophagus lining can change in ways that raise the risk of cancer if left unmonitored. Most people with Barrett’s feel completely normal. That’s precisely why it gets missed. Stomach and Duodenal Ulcers: Ulcers can bleed quietly for a long time before causing obvious pain. A gastroscopy finds them, lets us take biopsies, and in some cases treats bleeding on the spot. If your stomach pain wakes you at night, book a consultation – don’t keep waiting. H. pylori Infection: Pylori bacterial infection sits behind many cases of gastritis, ulcers, and – over years – an elevated risk of stomach cancer. We test for it directly by taking small tissue samples during the procedure. Gastritis: Inflammation of the stomach lining rarely shows on blood tests. But it shows clearly on gastroscopy. If you’ve been told your results are normal while symptoms carry on, this is often the finding people have been waiting for. Coeliac Disease: Small biopsies taken from the duodenum can confirm coeliac disease – a condition that goes undiagnosed in far too many people for far too long. Years of bloating, tiredness, and gut trouble, all with a treatable cause sitting quietly underneath. Oesophageal and Stomach Cancer: Early upper GI cancers frequently produce no symptoms, or symptoms that get attributed to something else. Found early, outcomes are considerably better. Unexplained weight loss, food sticking when you swallow, or persistent vomiting – these need investigation. Hiatus Hernia: When part of the stomach pushes through the diaphragm, it can drive reflux symptoms that just don’t respond to standard medication. Gastroscopy confirms it clearly and changes the treatment approach. Unexplained Anaemia: A slowly falling blood count with no obvious cause often points to silent bleeding somewhere in the upper GI tract. Gastroscopy finds the source. The Right Test for the Right Answer By the time most patients reach Harmony Digestive and Liver Wellness, they’ve already been through the standard tests. Normal results, still symptomatic, no real explanation. What Is a Gastroscopy Looking For? A gastroscopy doesn’t replace those tests – it goes further. It shows us the actual lining of your gut. That’s information blood work simply can’t give. You’re not being overly cautious by wanting a proper answer. You’re being sensible. If your gut is telling you something, it’s worth listening to.

What Causes Acid Reflux? When should you see a specialist?
What Causes Acid Reflux? Acid reflux is something millions of people deal with every day, like that burning sensation that creeps up your chest after a meal, the bitter taste that shows up in your mouth, or the feeling that food is sitting in the wrong place. It can feel uncomfortable, painful, and is often misunderstood. I’m Dr. Arjun Prakash, a Consultant Gastroenterologist. If you’ve been thinking about what is actually driving that burn and when it makes sense to see someone, here’s what I explain to my patients. What’s Actually Happening in Your Body Your stomach produces acid to do its job – breaking down food. There’s a small valve between your stomach and your esophagus called the lower esophageal sphincter. Think of it as a one-way door. When it’s working right, acid stays where it belongs. When it doesn’t close properly, acid travels back up. That’s what causes acid reflux – and that burning you feel is your esophagus reacting to something it was never meant to handle. Occasional reflux is one thing. When it’s happening twice a week or more, we call it GERD – and that’s when I want my patients to take it seriously. What Causes Acid Reflux – In My Patients, Here’s What I See Most Food triggers: Spicy food, fried meals, chocolate, citrus, tomatoes, coffee, and alcohol. I’m not asking you to give all of it up forever – but I do ask patients to keep a simple food diary for two weeks. Patterns show up fast. How and when you eat: Large meals, eating too quickly, lying down within an hour of eating – these habits put real pressure on your stomach. The acid has nowhere to go but up. Body weight: Extra weight around the belly presses directly on the stomach. I’ve had patients whose reflux improved significantly with a modest change in weight – no medication needed. A weakened valve: Sometimes the LES just isn’t functioning well – it could be something you’re born with, or it develops over time. Certain medications and even stress can make it worse. Hiatal hernia: A portion of the stomach pushes up through the diaphragm. Many patients are surprised to hear they have one – it’s often found incidentally and explains a lot of their symptoms. Pregnancy: I always reassure my pregnant patients – reflux during pregnancy is incredibly common and very much expected, especially in the third trimester. Smoking and certain medications: NSAIDs like ibuprofen, some blood pressure drugs – these can aggravate the esophagus or loosen the valve. If reflux started alongside a new prescription, please mention it. When Should You See a Specialist? Please don’t wait if you’re experiencing any of these: Reflux more than twice a week, consistently Antacids that used to help but no longer do Pain or difficulty when swallowing Unexplained weight loss Nausea, vomiting, or blood in your stool These aren’t meant to alarm you – but they are signs that your body is asking for more than an antacid. Left untreated, chronic reflux can damage the esophagus over time. Barrett’s esophagus is one complication I take seriously in my practice, and early evaluation makes a real difference in outcomes. Final Thoughts If you’ve been brushing off that burning feeling for months — or years, I should say — I want you to hear this clearly: it’s not just a problem you have to live with. Understanding What Causes Acid Reflux? is where it begins, but getting the right care is where things actually start to improve. You don’t have to figure this out alone. Visit Harmony Gut and Liver for trusted resources, and don’t hesitate to reach out to a specialist. Your gut health affects everything – sleep, energy, mood, daily comfort.

H. Pylori Treatment: Causes, Symptoms & Relief Explained
By Dr. Prakash Gupta, Consultant Gastroenterologist You may not realize it, but if you’ve been suffering from persistent abdominal discomfort, bloating, or frequent ulcers, the problem could be in your stomach – Helicobacter pylori, or H. pylori. This is a bacterial infection that affects almost half the world’s people, and many people are infected but don’t realize it. To obtain lasting relief from H. pylori symptoms, it is very important to understand the treatment method, causes, and symptoms of H. pylori. What Is H. Pylori? pylori is a spiral-shaped bacterium that lives in the lining of the stomach. Enables them to survive in the very acidic environment by secreting an enzyme called urease, which neutralizes stomach acid near it. This, over time, results in damage to the protective mucus layer, which results in inflammation and ulcers. Can H. Pylori be passed on? The infection is spread via: Consumption of contaminated drinking water or food or water not treated for chemical disinfection or drinking water not treated for chemicals. Infection transferred from person to person (such as by sharing food, sharing drinks, kissing, close contact with someone who has the infection) Exposure is greatly increased by living in poor sanitation – overcrowding or poor hygiene. The infection is all-ages, but is more likely to occur in children in developing countries. Common Symptoms to Watch For Many H. pylori-infected individuals don’t experience any symptoms. When they do occur, the symptoms are usually: Stomach pain that burns or gnaws, and may be worse when you are hungry Passing gas (or wind) multiple times after eating food Nausea which may be accompanied by vomiting Loss of interest in eating or loss of weight without an obvious cause Black or bloody stools (an indication of bleeding – see a doctor right away) A persistent feeling of fullness even after small meals If the abdominal pain is severe and worsening, immediately seek medical care. If left untreated, H. pylori may cause peptic ulcers and, in a few cases, stomach cancer. How is it diagnosed? There are a number of ways to confirm an H. pylori infection: Urea breath test– a solution is swallowed; CO₂ is detectable if H. pylori is present and the compound is broken down by it Stool antigen test– tests for bacterial protein in stool. Blood antibody test– identifies antibodies, but does not confirm the presence of an active infection. Biopsy or endoscopy–used if there are other symptoms or ulcers that require further examination Pylori Treatment Options Standard H. pylori treatment is called triple therapy or quadruple therapy when H. pylori is resistant to the therapy. Both are medications that contain antibiotics and stomach acid-digesting drugs. Triple Therapy (7–14 days): Two antibiotics (usually clarithromycin + amoxicillin or metronidazole) A proton pump inhibitor (PPI) such as omeprazole to help the stomach heal and so stop the acid from hurting the esophagus. Quadruple Therapy (resistance suspected): Two antibiotics A PPI Taking bismuth subsalicylate to help prevent irritation of the stomach lining. It’s important to take the entire course of antibiotics. Early eradication helps prevent the development of resistance to antibiotics and will make the infection much harder to eradicate the second time. Natural Support During Treatment In addition to prescribed drugs, some lifestyle changes can help with recovery: Probiotics (particularly Lactobacillus species) support the restoration of an imbalance in gut flora caused by antibiotics. Please don’t use alcohol, spicy foods, or NSAIDs during the treatment; these irritate the lining of the stomach. Eat moderately-sized meals several times a day to decrease acid load. In studies, green tea and broccoli sprouts have exhibited some antibacterial activity, but cannot replace medications. After Treatment: Verification of eradication A breath test or stool test follows up H. pylori treatment, 4 weeks later to see if it has been eradicated. Re-testing is important because re-infection can occur, particularly when there is no change in the hygiene practices. Final Thoughts pylori is ubiquitous, but highly treatable. When symptoms first appear, most patients can enjoy full relief of symptoms and avoid further complications by following the proper treatment plan for H. pylori infections. If you’ve ever experienced stomach pain that won’t go away, be sure to get tested – it may be the difference between life and death. At Harmony Digestive and Liver Wellness, we offer complete H. pylori investigation and treatment under one roof — testing, diagnosis, and a clear plan.

What Is a Gastroscopy? When do you need it?
By Dr Arjun Prakash, Consultant Gastroenterologist If you’ve been told you need a gastroscopy, there’s a good chance your first reaction wasn’t relief. It was probably Google. And Google, as it tends to do, gave you something to worry about. So let me tell you what I tell my patients when they sit across from me, phone already in hand: What Is a Gastroscopy? It’s one of the most straightforward investigations we have. It’s brief, it’s well-tolerated, and more often than not, it gives people answers they’ve been quietly waiting for. What Is a Gastroscopy? What is a gastroscopy, in plain terms? It’s a gentle, direct look inside your oesophagus, stomach, and the upper part of your small intestine – using a thin, flexible tube with a small camera at the tip. The whole thing takes around ten to fifteen minutes. You’re given either a throat spray or light sedation, and most patients tell me afterwards they barely noticed it happening. It’s sometimes called an upper endoscopy or OGD. The medical name is long. The experience, thankfully, isn’t. Why Your Symptoms Deserve a Proper Answer Digestive discomfort has a way of becoming background noise. You get used to the bloating. You keep antacids in your bag. You tell yourself everyone deals with reflux. And maybe they do, but that doesn’t mean yours should go uninvestigated. The upper digestive tract is one part of the body we simply cannot assess from the outside. Blood tests, scans, and symptom questionnaires all have their place – but none of them shows the lining of your stomach. Only a camera does that. And what it finds changes everything: a peptic ulcer, gastritis, Barrett’s oesophagus, coeliac disease, or occasionally something that needs urgent attention. Most of the time, what it finds is reassurance. That matters too. When to Stop Waiting and Get Checked You don’t need to be in crisis to deserve an investigation. But there are symptoms I take seriously straightaway, and I want you to take them seriously too: Food that sticks or feels like it’s getting caught when you swallow Heartburn or reflux that keeps coming back despite medication Unexplained weight loss, even if it seems small Persistent nausea or vomiting – especially with any blood present A dull, recurring ache in the upper abdomen that antacids don’t touch Iron-deficiency anaemia that no one has fully explained I’d also gently say this: if you’re over 45 and experiencing new digestive symptoms that feel different from what you’ve had before, please don’t dismiss them. The age threshold exists for a reason. What the Experience Is Actually Like I want to address the anxiety directly, because it’s real and I hear it often. Most patients choose sedation – a light dose that leaves you drowsy, relaxed, and with very little memory of the procedure itself. You won’t be put to sleep. You’ll simply feel calm. The camera passes while you breathe normally. There’s no cutting, no stitches, and you’ll be home within a couple of hours. Afterwards, you might notice mild bloating or a faint throat soreness. That typically settles by the same evening. If anything unusual is seen – an inflamed patch, a small growth, tissue that looks different – a biopsy can be taken at that same moment. No second appointment. No waiting to find out if something needs sampling. One visit does the work. More Than Just a Diagnosis What I want patients to understand is that gastroscopy isn’t only about finding problems – it’s also about fixing them. Bleeding ulcers can be treated during the procedure. Polyps can be removed. Narrowed sections can be opened up. In many cases, the investigation and the intervention happen in the same room, on the same day. A Final Word If you’ve been managing symptoms for months — or years — and never been properly investigated, I understand why. Life is busy. Symptoms come and go. It feels easier to cope than to question. But coping isn’t the same as understanding. And understanding, especially what is a gastroscopy, when it comes to your digestive health, can make an enormous difference — not just medically, but in how you feel day to day. A gastroscopy is a short procedure. The peace of mind — or the early diagnosis — it provides can last much longer. At Harmony Digestive and Liver Wellness, we walk you through every step before, during, and after your gastroscopy – so you’re never left with unanswered questions or a report you have to decode alone.

What Is SIBO? Symptoms, Causes & Treatment Explained
If you’ve been bloated after every meal, dealing with unpredictable bowel habits, and getting nowhere despite cutting out food after food, there’s a condition most people haven’t heard of that could explain everything. It’s called SIBO: Small Intestinal Bacterial Overgrowth. It’s underdiagnosed, frequently mistaken for IBS, and in most cases, very treatable. The problem is simply getting to the right diagnosis. I’m Dr Prakash Gupta, a Consultant Gastroenterologist. SIBO is underdiagnosed, frequently misattributed to IBS, and in most cases, very treatable. The problem is simply getting to the right diagnosis. What Exactly Is SIBO? Your digestive system hosts trillions of bacteria — mostly beneficial, but location matters. Your large intestine is built to handle high bacterial populations. Your small intestine is not. SIBO occurs when bacteria migrate upward and colonise the small intestine in numbers it can’t manage. Once there, they ferment your food before your body absorbs it properly — producing excess gas, inflammation, and a gut that feels permanently off. This isn’t a traditional infection. It’s the wrong organisms in the wrong place. Symptoms of SIBO: What to Look For SIBO doesn’t tend to announce itself with one dramatic symptom. It’s usually a cluster of things that have been building for months — sometimes years. The most common ones I see: Persistent bloating, particularly after meals — often described as a ‘balloon’ sensation that builds throughout the day Abdominal discomfort, cramping, or a general sense of pressure in the gut Unpredictable bowel habits — this can mean constipation, loose stools, or both alternating Excessive gas and flatulence that seems out of proportion to what you’ve eaten Unexplained fatigue — when your gut isn’t absorbing nutrients efficiently, the rest of your body feels it In longer-standing cases: deficiencies in B12, iron, or fat-soluble vitamins (A, D, E, K) You may find that certain foods — particularly those containing onions, garlic, legumes, or wheat — seem to make things significantly worse. This is because these foods are rapidly fermented by bacteria, and in SIBO, there are far too many bacteria to manage that fermentation process properly. What Causes SIBO? In most cases, SIBO develops because something has disrupted the small intestine’s ability to keep bacteria moving through and prevent them from settling in. A few of the most common underlying mechanisms: Sluggish gut motility — The small intestine uses rhythmic contractions (the migrating motor complex) to sweep bacteria forward. When this slows — common in diabetes, thyroid conditions, or after abdominal surgery — bacteria accumulate. Low stomach acid — Acid is a frontline defence against bacterial overgrowth. Long-term use of PPIs like omeprazole quietly erodes that protection without most people realising. Structural changes — Surgical adhesions or strictures create stagnant zones were bacteria multiply unchallenged. Post-infectious damage — A single serious bout of food poisoning or gastroenteritis can permanently alter gut motility, leaving the small intestine sluggish and vulnerable long after recovery. Treatment: What Actually Works A simple hydrogen and methane breath test — no needles, no hospital. You fast overnight, drink a sugar solution, and breathe into tubes for over two hours. Elevated gas readings confirm overgrowth. Treatment: Rifaximin is the first-line antibiotic — works directly inside the gut, barely enters the bloodstream Minimal side effects compared to standard antibiotics Most patients notice real improvement within two weeks For methane-dominant SIBO, a second antibiotic is often added for better results The root cause must be addressed — motility, acid suppression, or structural issues — or SIBO returns A low-FODMAP diet runs alongside antibiotics to reduce foods that feed bacterial fermentation Low-FODMAP is short-term only — not a permanent diet, but genuinely helpful during recovery Full symptom resolution typically happens within a month of completing treatment A Final Word If you’ve had ongoing digestive symptoms, a normal colonoscopy, and no clear diagnosis — that’s the pattern that should prompt a SIBO conversation. You don’t need to have every symptom on the list. If bloating after meals, unpredictable bowel habits, and persistent gut discomfort have been part of your life for more than a few months — especially if standard investigations haven’t given you answers — it’s time to look further.

Does IBS Cause Bloating? When is it IBS and when should it be investigated?
Bloating gets blamed on everything. Too much bread. Eating too fast. A stressful week. And sometimes, that’s exactly what it is. But when it keeps coming back – week after week, meal after meal – it deserves a more careful answer. Does IBS cause bloating? Yes, it does. IBS is known to cause bloating, often in the form of fullness, pressure, or visible distension. I’m Dr Arjun Prakash, a Consultant Gastroenterologist. If you’ve been living with persistent bloating and told there’s nothing to investigate, this is worth reading. Because the answer isn’t always IBS – and even when it is, IBS deserves better than a label with no plan behind it. What Is IBS – and Does IBS Cause Bloating? Irritable bowel syndrome is a functional gut condition – meaning the bowel looks structurally normal, but behaves abnormally. The gut becomes hypersensitive, reacting disproportionately to ordinary amounts of gas, food, or movement. The result is a pattern of symptoms: abdominal discomfort, unpredictable bowel habits, and yes – bloating. So does IBS cause bloating? It does. Patients describe it as fullness, pressure, or visible distension – often building through the day and worsening around meals or periods of stress. But here’s what matters clinically: IBS is a diagnosis of exclusion. Before that label is applied, other causes need to be confidently ruled out. Bloating is equally a feature of coeliac disease, small intestinal bacterial overgrowth (SIBO), inflammatory bowel disease, ovarian conditions, and – in cases that cannot be missed – early gastrointestinal malignancy. What IBS Bloating Actually Feels Like IBS-related bloating tends to follow a recognisable pattern. It: Fluctuates – better some days, worse on others Worsens after eating, particularly foods high in fermentable carbohydrates (FODMAPs) Is linked to a change in bowel habit – either loose stools, constipation, or alternating between the two Improves, at least partially, after opening the bowels Tracks closely with stress, anxiety, or disrupted sleep A diagnosis of IBS should never be the end of the conversation. It should be the beginning of one – with a clear management plan, not just a name for what you’re experiencing. When Bloating Needs More Than Reassurance This is where I ask patients to pay close attention. Certain features alongside bloating suggest the gut needs investigating beyond a clinical consultation alone: Unintentional weight loss – even a few kilograms over a few months Rectal bleeding or blood mixed into stools Bloating that is constant rather than fluctuating – a distension that doesn’t ease overnight New bloating in someone over 50 with no prior gut history Waking at night with abdominal discomfort A family history of bowel cancer, ovarian cancer, or inflammatory bowel disease Any one of these changes the conversation. These aren’t IBS features. They’re red flags – and they warrant urgent specialist review. How We Actually Investigate It A thorough workup for persistent bloating starts with blood tests: inflammatory markers, coeliac antibodies, thyroid function, and a full blood count. Stool calprotectin tests can distinguish functional gut symptoms from active inflammation with high accuracy. Depending on findings, the investigation may extend to a colonoscopy, a hydrogen breath test for SIBO, or cross-sectional imaging. The right pathway depends on the full clinical picture – which is why a specialist consultation is the most efficient route to answers. A Final Word Does IBS cause bloating? Yes. But bloating causing you concern deserves more than a label. It deserves a clear diagnosis, a proper exclusion of other causes, and a management plan that actually works. If your bloating is persistent, worsening, or comes with any of the red-flag features above, don’t wait it out.

Liver Function Blood Test: Do normal liver function blood test rule out liver disease?
Normal doesn’t mean healthy. In liver medicine, it sometimes just means we haven’t looked closely enough yet. The patient sitting across from me has done everything right. They got tested. The results looked fine. Their GP wasn’t concerned. And yet here they are – because something still doesn’t feel right, and it turns out their instinct was correct. I’m Dr Prakash Gupta, a Consultant Gastroenterologist. The liver function blood test is one of the most ordered tests in medicine – and one of the most misread. Here’s what those results actually tell you, and what they quietly leave out. What a Liver Function Blood Test Actually Measures A standard liver function blood test checks a panel of enzymes and proteins: ALT, AST, ALP, GGT, bilirubin, albumin, and total protein. These markers tell us how the liver is performing certain jobs – processing waste, making proteins, and clearing bilirubin. What they don’t tell us is the full story. Each marker reflects a narrow slice of liver health. And crucially, they reflect the liver right now – not the slow, silent damage that may have been accumulating for years. The Problem With “Normal” Here’s the part that surprises most patients: a liver function blood test can appear entirely normal even when significant liver disease is already present. In conditions like early fatty liver (NAFLD/MASLD), liver enzymes often sit comfortably within the normal range – even when ultrasound or elastography reveals fat accumulation or early fibrosis. In hepatitis C, some patients carry the infection for decades with near-normal liver enzymes while the virus quietly scars the liver. In cirrhosis, once the liver has already lost a significant portion of its functional tissue, enzyme levels can paradoxically normalise – because there are fewer healthy cells left to release them. A normal result means the liver isn’t shouting. It doesn’t mean the liver isn’t struggling. What “Raised” Enzymes Actually Mean If your liver function blood test does show elevated enzymes, that’s worth taking seriously – but raised levels alone don’t tell you why. ALT and AST can be elevated in fatty liver, viral hepatitis, alcohol-related liver disease, medication effects, thyroid problems, and even vigorous exercise. Context matters enormously. A mildly raised result brushed off as “nothing to worry about” without further investigation is a missed opportunity. A significantly elevated result that gets traced, investigated, and treated can genuinely change the outcome. What Needs to Come Next A liver function blood test is a starting point, not an endpoint. If your results are abnormal – or if you have risk factors even with normal results – the investigation needs to go further. That typically means: A liver ultrasound, which can detect fatty change, structural abnormalities, and lesions that blood tests simply cannot. Elastography (FibroScan), which measures both the amount of fat in the liver and the degree of scarring – two pieces of information that change clinical decisions entirely. Targeted blood tests, including viral hepatitis screens, autoimmune markers, and iron studies, depending on the clinical picture. The liver function blood test opens the door. These tests tell you what’s actually behind it. Who Should Go Further – Even With Normal Results If any of the following apply to you, a normal liver function blood test is not sufficient reassurance on its own: You have type 2 diabetes or insulin resistance You carry excess weight, particularly around the abdomen You have high triglycerides or metabolic syndrome You drink alcohol regularly, even at moderate levels A family member has been diagnosed with liver disease You’ve had a fatty or enlarged liver noted on a previous scan In these situations, I recommend a full liver assessment regardless of what the blood panel shows. A Final Word Early liver disease is treatable. Cirrhosis is not reversible. The liver function blood test is a valuable tool – but placing too much reassurance in a normal result can create a false sense of safety in exactly the patients who need further investigation most. If you have risk factors, or if something about your health doesn’t add up, don’t stop at the blood test.

Can Fatty Liver Be Reversed? Effective Ways to Improve Liver Health
You have just been told you have fatty liver — and the first thing you want to know is whether this is permanent. I am Dr Arjun Prakash, Consultant Gastroenterologist and Hepatologist. The most common question I hear after a fatty liver diagnosis is simple: Can fatty liver be reversed? For most people who act early, the answer is yes. Why It Often Goes Unnoticed Fatty liver builds up quietly. Fat accumulates within liver cells, gradually making the liver work harder — and in many cases, patients feel nothing unusual at all. No pain, no obvious warning. The diagnosis often arrives through a routine blood test or abdominal scan, which is why an abnormal liver test result should always be taken seriously and followed up properly. Can Fatty Liver Be Reversed? In the early stages, yes. The liver has a strong capacity to heal itself when the right changes are made in time. Once liver fibrosis begins — meaning scar tissue starts to form — reversal becomes harder, though slowing progression and achieving partial recovery is still possible. At the stage of advanced cirrhosis, the goal shifts to careful management rather than reversal. This is why knowing exactly where you stand matters. A liver function test, a liver ultrasound scan, and a FibroScan assessment can map out the current state of your liver — painlessly and quickly. The earlier we look, the more we can do. What Actually Makes a Difference There is no single pill that reverses fatty liver. What works is a combination of consistent, practical changes. Losing weight steadily: For patients carrying excess weight, losing five to ten percent of body weight can meaningfully reduce liver fat. Gradual loss matters here — crash dieting puts additional stress on the liver rather than relieving it. Changing what you eat: A fatty liver disease diet focused on vegetables, whole grains, oily fish, and healthy fats works well. Cutting back on processed foods, added sugars, and refined carbohydrates reduces the daily burden on the liver. A diet that supports liver repair does not need to be complicated — it just needs to be consistent. Reducing alcohol: Even in non-alcoholic fatty liver, alcohol adds unnecessary pressure to an already strained organ. For alcohol-related liver disease, cutting back — or stopping — is the most important step of all. Regular physical activity: Regular moderate exercise, even thirty minutes of walking most days, helps the body burn stored fat, including liver fat. You do not need to do anything extreme. Looking after your gut: The gut and liver are closely connected. An imbalanced gut directly contributes to liver inflammation. Working on how to improve gut health supports liver recovery in ways many patients do not initially expect. A Word on Acting Early Patients sometimes tell me they wish they had come sooner. Early signs of liver disease are subtle, and it is easy to explain away fatigue or mild discomfort. But early-stage fatty liver, identified and addressed promptly, carries a genuinely good prognosis. Waiting until symptoms become more obvious means waiting until the disease has progressed further — and that narrows the options we have available. A Final Word At Harmony Digestive and Liver Wellness, we offer specialist liver assessment, including liver function testing, liver ultrasound, FibroScan-style liver stiffness evaluation, and consultant-led interpretation of your results. If you have been told you have fatty liver, received an abnormal liver blood test result, or are simply concerned about your liver health, please do not wait. Can Fatty Liver Be Reversed? With early assessment, the right lifestyle changes, and expert medical guidance, fatty liver can often be managed effectively before it leads to serious complications. Early assessment can make a significant difference to your long-term outlook — and we are here to guide you through every step of that process. Book a consultation or screening today: Click Here.

FibroScan vs Ultrasound: Understanding the Key Differences
You’ve probably heard both terms mentioned — FibroScan vs Ultrasound — and wondered whether they’re the same thing, or why your doctor might recommend one over the other. It’s a question I get asked a lot in the clinic. I’m Dr Prakash Gupta, Consultant Gastroenterologist and Hepatologist at Harmony Digestive and Liver Wellness. Let me explain the difference in straightforward terms, because it genuinely matters for how we look after your liver. What a Liver Ultrasound Actually Does Most people have had an ultrasound at some point. It’s the same technology used in pregnancy scans — sound waves that bounce off tissue and create an image on screen. The liver gives us a visual overview of the organ. A liver ultrasound is useful for spotting: Obvious fatty changes or an enlarged liver Gallstones and bile duct problems Liver cysts or masses Signs of structural abnormality It’s a good starting point. If you’ve come in with abnormal liver blood tests or unexplained abdominal symptoms, an ultrasound is often the first thing I’ll arrange. But here’s what most patients aren’t told: a standard ultrasound cannot measure scarring inside the liver. It can tell me your liver looks fatty, or slightly enlarged, or a little irregular — but it can’t tell me whether there’s significant fibrosis building up beneath the surface. And that, unfortunately, is often the thing that matters most. What a FibroScan Does Differently FibroScan — the medical term is transient elastography — was developed specifically to fill that gap. It measures how stiff the liver is. Stiffness and scarring go hand in hand: the more fibrosis that has built up over time, the stiffer the liver becomes. The way it works is quite elegant. A small probe sits against your skin, just below the ribs on the right side. It sends a gentle vibration into the liver and measures how quickly that vibration travels through the tissue. A soft, healthy liver slows it down. A stiff, scarred liver lets it pass through faster. The machine converts that into a number — expressed in kilopascals — and that number tells us a great deal about where things stand. Here’s what the experience is actually like for patients: The whole test takes around 10–15 minutes There are no needles and no sedation You just need to avoid eating for 2–3 hours beforehand Results are available straight away Most patients tell me they were surprised by how unremarkable it was So Which One Do You Actually Need? The honest answer is: it depends on what question we’re trying to answer. A liver ultrasound is the right tool when: We want a structural overview of the liver and surrounding organs There’s a concern about gallstones, masses, or obvious fatty changes It’s a first-step investigation for new symptoms or raised blood tests A FibroScan is the right tool when: We need to know how much scarring or fibrosis is actually present We want to stage liver disease and monitor whether it’s progressing The ultrasound has flagged something, and we need to understand it better For many patients, both have a role. An ultrasound might be the first step, and FibroScan follows to stage whatever has been found. If you’re also dealing with digestive symptoms alongside your liver concerns — bloating, discomfort, changes in bowel habit — it’s worth reading about gut inflammation symptoms, because the two are sometimes connected. Why This Distinction Actually Matters Liver disease is, frustratingly, often silent. I see patients in the clinic who feel absolutely fine and are shocked to learn they have significant fibrosis. By the time symptoms show up — fatigue, jaundice, fluid retention — the liver can already be under considerable strain. You may benefit from liver stiffness testing if you have: Fatty liver was identified on a previous ultrasound Raised liver enzymes or abnormal liver blood tests Type 2 diabetes or metabolic syndrome Significant or regular alcohol intake A history of hepatitis B or C Obesity or high cholesterol A family history of liver disease Even if you feel entirely well, any of these risk factors is a good reason to get a clearer picture. Early fibrosis can often be stabilised or reversed. Once liver disease reaches an advanced stage, the options narrow significantly — and that shift can hinge on whether the problem was caught at the right time. Thinking About Getting Assessed? If you’ve been told you have a fatty liver, your liver enzymes have come back raised, or you simply want to understand your liver health properly, a specialist assessment is the right next step.
