You can eat some bananas appropriately the day before the gastroenteroscopy.
The day before the gastroenteroscopy is not able to eat as usual, because there is a certain limitation of eating because the bowel preparation before the examination needs to be done and the gastrointestinal tract needs to be emptied so that the surface of the gastrointestinal tract can be clearly observed in order to get the accurate examination results.
Eating should be minimized the day before the examination, and some easily digestible foods can be consumed, such as bananas and millet porridge. Banana can promote gastrointestinal peristalsis, and contains fiber, minerals, etc., which helps promote defecation and clean the intestines. Millet porridge is rich in nutrients and contains many micronutrients, which can replenish the carbohydrates needed by the human body and can help to clear the intestinal tract of hangover.
It is recommended that bowel preparation be done under the guidance of a doctor to avoid adverse effects.
