Endoscopic examinations, such as gastroscopy (gastroscopy) or the colonoscopy (colonoscopy) are essential for making an accurate diagnosis. The success of the examination and the patient’s comfort depend to a large extent on proper preparation and post-procedure recovery. The Endomedix Gastroenterology Centre Their expert advice helps to ensure that the process runs smoothly.
Lifestyle before the test: Diet and fluid intake
The aim in every case is to ensure that the mucous membrane is clear, so that the doctor can spot even the smallest abnormalities.

- Meals: Before the test 6–8 hours You must no longer eat solid food.
- Liquid: Before the procedure 2–4 hours You should also stop drinking water and tea.
2. Colonoscopy (examination of the large bowel)
- 3–4 days beforehand: A low-fibre diet. Avoid seeds (poppy seeds, sesame seeds), fruit skins (tomatoes, grapes) and wholemeal bread and pastries.
- 1 day before: You should now only consume clear, transparent liquids (strained stock, water, weak tea). This is also when you should take the laxative solution.
- Important: Avoid red or dark blue drinks, as they can give the appearance of bleeding in the bowel!
Taking Medication: What Should We Bear in Mind?
Certain medicines may affect the course or risks of the test:
- Anticoagulants: Only the treating doctor may decide whether to discontinue or substitute these (e.g. LMWH injections)!

- Diabetes: If you are fasting, you should discuss your insulin or tablet doses with your diabetologist.
