Introduction
Gastrointestinal endoscopy generally refers to both colonoscopy and gastroscopy. Two days before a colonoscopy, you should consume low-fiber foods such as noodles and millet porridge. This helps keep the bowel clean and improves the accuracy of the colonoscopy. For gastroscopy, two days prior to the examination, you should eat easily digestible foods to avoid burdening the stomach and affecting test results. Suitable options include steamed buns, noodles, and rice.
Gastrointestinal endoscopy generally refers to both colonoscopy and gastroscopy. Two days prior to the procedure, it is recommended to consume low-fiber foods to ensure a clean digestive tract, which facilitates better visualization during the examination.
Colonoscopy is a method used to examine the intestines, primarily involving insertion of the scope through the anus into the rectum and then advancing into the large intestine to observe the condition of the colon and rectum. For two days before the colonoscopy, patients should eat low-fiber foods such as noodles or millet porridge. After eating on the evening before the procedure, complete fasting is required to maintain a clean bowel, thereby improving the accuracy of the examination.
Gastroscopy involves inserting a thin, flexible tube through the mouth into the throat to examine the esophagus, stomach, and duodenum, and is the preferred diagnostic method for upper gastrointestinal disorders. Two days before the procedure, patients should consume easily digestible foods to avoid placing excessive burden on the stomach, which could affect the results. Foods such as steamed buns, noodles, and rice are suitable. Additionally, strict fasting must be observed for at least eight hours before the examination to prevent food retention in the stomach, which could interfere with visualization and potentially cause discomfort or vomiting during the procedure.
