During a gastroscopy a thin tube-like telescope is inserted through your mouth to look for any problems in your oesophagus (gullet), stomach and duodenum (part of the small intestine). Diagnosing such problems is a key step to help you get the relief and treatment you need to start living a full life again.
A referral letter from a consultant or GP is required before booking any diagnostic investigation.
A gastroscopy (or endoscopy) can tell your doctor a lot about the possible causes of any problems you have in the gullet, stomach or small intestine. It’s also a useful and painless way for doctors to check how diagnosed gastrointestinal conditions are progressing.
It can be used to treat conditions such as enlarged veins or bleeding ulcers.
You might be referred for a gastroscopy if you have any of a range of symptoms, many of which will be uncomfortable and affect your enjoyment of life. They can include:
The procedure involves passing a long, thin telescopic tube through your mouth and throat into the gullet and stomach, usually after you’ve been sedated.

Our dedicated team will also give you tailored advice to follow in the run up to your visit.
It’s likely that both a doctor and nurse will be involved in the procedure. They understand that people can get anxious as it approaches. They’ll answer any questions you have and be there for you to provide reassurance.
You’ll remain conscious during the 10 to 30 minute procedure, although you’ll probably have had a mild sedative so you may feel very relaxed. Your clinician might also use a spray to numb your throat. You’ll be able to breathe comfortably as the tube will not be fed through your windpipe.
The doctor will then thread the tube (or endoscope) with a tiny camera on the end into your gullet and stomach. This will allow them to see pictures of what is happening in those areas.
You might feel a bit bloated at times as the clinician will pump gas into your stomach.
The tube might also take a tissue sample (a biopsy) for study in one of our labs.
The clinician will then withdraw the endoscope.
After this, you will be taken to your room or comfortable area where you can rest and recuperate until we feel you’re ready to go home.
If you've had an anaesthetic you’ll need a friend or relative to get you home. You’ll feel drowsy for a few hours and possibly into the next day. You might have sore throat or feel bloated around the stomach.
You might not be able to eat your normal diet for a few days depending on the type of gastroscopy you’ve had. We will advise you accordingly.
If your test was part of a range of diagnostic procedures coordinated by a Spire consultant the results should be ready several days later. We may need to make a follow-up appointment with you to discuss the results.
We take an integrated approach so we can organise any other care that you may need should your test results show something abnormal.
Even once you’ve left hospital, we’re still here for you.
On rare occasions, complications following treatment can occur. If you experience any of these symptoms vomiting blood, breathing difficulties, acute pain in the neck, chest or stomach - please call us straight away.
