Some still experience burning behind the breastbone. Others describe regurgitation, an unpleasant taste, upper abdominal discomfort, nausea, coughing or disturbed sleep. When acid reflux continues despite omeprazole, the diagnosis and treatment need a structured review. The assessment starts with the symptom pattern and how the medicine is being taken, followed by a decision about whether gastroscopy or reflux testing is likely to alter management. Persistent symptoms can arise from continuing acid reflux, non-acid reflux, a hiatus hernia, oesophageal hypersensitivity, functional heartburn, eosinophilic oesophagitis or an oesophageal motility disorder. Symptoms affecting the chest or throat may also have another cause. Still experiencing reflux symptoms despite omeprazole? I can review the diagnosis, how the medication is being used, previous results and any warning features, then advise whether treatment adjustment, gastroscopy or oesophageal testing is appropriate. What does omeprazole do? Omeprazole is a proton pump inhibitor, commonly shortened to PPI. It suppresses acid production in the stomach and is frequently prescribed for gastro-oesophageal reflux disease, reflux oesophagitis and peptic ulcers. It can be very effective when symptoms are driven by acid exposure in the oesophagus. The response also depends on the dose, timing and accuracy of the underlying diagnosis. Check how you are taking omeprazole I establish when each dose is taken, how regularly it is taken and which symptoms respond. For many patients, omeprazole works best approximately 30 to 60 minutes before a meal, usually breakfast. When prescribed twice daily, the second dose is generally taken before the evening meal. Taking it after food, at bedtime or only when symptoms become severe may reduce its effectiveness. Patients should seek medical advice before changing the dose or stopping treatment, particularly when it was prescribed for severe oesophagitis, an ulcer, Barrett&#8217;s oesophagus or protection against bleeding. Why can reflux symptoms continue despite omeprazole? Continuing acid reflux Clinically significant acid reflux can continue despite treatment, particularly with a hiatus hernia, obesity, impaired function of the lower oesophageal sphincter or more severe GORD. Regurgitation and non-acid reflux Omeprazole suppresses gastric acid. Fluid and food can still move from the stomach into the oesophagus, so regurgitation may continue even when the refluxate is less acidic. Combined pH and impedance monitoring can assess this in selected patients. Reflux hypersensitivity A sensitive oesophagus can generate significant symptoms during reflux episodes that fall within a physiological range. Reflux monitoring may show a close relationship between episodes and symptoms. Functional heartburn Functional heartburn causes recurrent burning despite normal endoscopy and normal acid exposure. Continued escalation of acid suppression is unlikely to provide sustained benefit once objective testing has excluded pathological reflux. Other oesophageal conditions Eosinophilic oesophagitis can cause swallowing difficulty, food sticking and chest discomfort. Achalasia and other motility disorders can cause regurgitation, chest pain and dysphagia. Rumination and supragastric belching may also resemble severe reflux. Symptoms arising elsewhere Chest pain requires careful assessment because cardiac disease can resemble reflux. Upper abdominal pain, nausea and bloating may relate to dyspepsia, gastric or biliary disease. Cough, throat clearing and hoarseness have several possible causes. When should persistent reflux be assessed promptly? Difficulty swallowing or food sticking Pain on swallowing Unintentional weight loss Persistent vomiting Vomiting blood or passing black, tarry stools Iron-deficiency anaemia Persistent loss of appetite Symptoms that are progressively worsening A strong family history of cancer affecting the oesophagus or stomach Severe or unfamiliar chest pain associated with breathlessness, sweating, dizziness or pain extending into the arm, shoulder, back or jaw requires emergency assessment. When is gastroscopy needed for acid reflux? Gastroscopy allows direct examination of the oesophagus, stomach and first part of the small bowel. It may be appropriate when symptoms persist after an adequate course of treatment, return repeatedly when treatment stops, or are accompanied by swallowing difficulty, bleeding, anaemia, vomiting or unexplained weight loss. It can identify oesophagitis, ulceration, a peptic stricture, hiatus hernia and Barrett&#8217;s oesophagus. Biopsies can be taken when eosinophilic oesophagitis or another mucosal condition is being considered. A normal gastroscopy is reassuring. Many patients with GORD have a normal-looking oesophagus, and gastroscopy cannot measure reflux during an ordinary day. Reflux monitoring may still be useful when symptoms remain intrusive. When symptoms persist after a reasonable course of treatment A consultation can establish whether gastroscopy is clinically justified, whether reflux testing would be more informative and whether another diagnosis should be considered. What reflux tests are available? Ambulatory pH monitoring Ambulatory pH monitoring measures acid exposure in the oesophagus during normal daily activities. When GORD has not been objectively established, testing is usually performed off acid suppression under clinical instruction. Combined pH and impedance monitoring This test detects movement of liquid and gas and assesses acidic, weakly acidic and non-acidic reflux. In a patient with previously proven GORD and symptoms despite optimised treatment, testing on therapy may help establish whether ongoing reflux is responsible. Oesophageal manometry High-resolution manometry measures oesophageal contractions and sphincter function. It may be recommended for dysphagia, suspected achalasia, unexplained regurgitation or before certain anti-reflux procedures. Can lifestyle changes help? Useful measures depend on the symptom pattern. They may include weight reduction where appropriate, avoiding meals within two or three hours of bedtime, elevating the head of the bed for night-time reflux, reducing individually identified triggers, moderating alcohol and stopping smoking. I do not routinely advise broad food exclusion without a consistent relationship to symptoms. Extensive restriction can complicate eating while leaving the cause unresolved. Why an online answer cannot diagnose persistent reflux I start with the symptoms that remain: heartburn, regurgitation, chest pain, dysphagia, cough and upper abdominal discomfort each guide the assessment differently. I then review the timing and dose of omeprazole, other medicines, previous investigations and any warning features. Some patients need a correction or adjustment to treatment. Others require gastroscopy, biopsies, reflux monitoring or oesophageal manometry. In a proportion of patients, the assessment shows that reflux is unlikely to account for the continuing symptoms.
