Patients go quiet when I mention gastroscopy. Then comes the question they were already thinking: Do I have to be sedated?
The honest answer is no. And for many of my patients, gastroscopy without sedation turns out to be far less daunting than they expected.
I’m Dr. Prakash Gupta, Consultant Gastroenterologist. Here’s the real picture.
Why We Do a Gastroscopy?
A gastroscopy lets me look directly inside your oesophagus, stomach, and the first part of your small intestine. I use it to investigate:
- Persistent reflux or heartburn
- Unexplained nausea or vomiting
- Difficulty swallowing
- Upper abdominal pain
- Abnormal liver or gut blood results
If you’ve been referred for one, there’s a specific reason. Don’t put it off.
What “Without Sedation” Actually Means
It doesn’t mean without anything.
Your throat is numbed with a local anaesthetic spray before we begin. That’s all. No IV line, no recovery room, no one needed to drive you home.
You stay awake and aware throughout. Most patients find that far less frightening once they actually understand what the procedure involves.
The Procedure, Step by Step
Before you arrive: Fast for at least six hours – nothing to eat or drink.
On arrival: The team reviews your history and medications. The throat spray is applied and given a few minutes to work.
During the procedure:
- You lie on your left side
- A small mouth guard is placed between your teeth
- The endoscopist gently passes a thin flexible tube through your mouth and throat
- Air is introduced to open the stomach walls for a clear view – this creates a full, bloated sensation, but it passes quickly
- The entire examination takes five to ten minutes
The moment most patients brace for is the scope entering the throat. What they feel is pressure, not pain. Breathing steadily through your nose is the single most useful thing you can do – it helps the body relax, and the tube move more easily.
Straight After the Procedure
The throat numbness fades within thirty to sixty minutes.
After that:
- Eat and drink normally
- Drive yourself home
- Return to work the same day
- Hear your results immediately – and actually remember them
That last point matters more than people realise. Sedated patients often retain very little of what’s explained to them post-procedure. You don’t have that problem here. Read more about what to expect from gut investigations.
Who Is This Right For?
Gastroscopy without sedation works well for patients who:
- Have had a gastroscopy before and know what to expect
- Want minimal disruption to their day
- Have no companion available to drive them home
- Prefer to stay alert and hear results in real time
It’s not the right choice for everyone. Patients with significant anxiety, a pronounced gag reflex, or those needing a therapeutic procedure alongside the diagnostic look may genuinely be better off sedated. There’s no shame in that – the goal is the right outcome for you, not a badge for toughing it out.
The Honest Truth About Discomfort
I won’t tell you it’s completely comfortable.
The scope passing through the throat is briefly unpleasant. What I can tell you is that it’s short, and the majority of patients who were nervous beforehand tell me afterwards it was nothing as they feared.
The throat spray does its job. The procedure is faster than most people expect. And unlike sedation, you walk out the door feeling entirely like yourself. Learn more about managing gut symptoms in the lead-up to your investigation.
