Do not eat cold, greasy, fried, hard or hot foods, or foods that are too stimulating, such as chili, ginger, coffee, strong tea, alcohol, cigarettes or Coca-Cola. Patients should chew food slowly and not overeat to prevent rebleeding in the digestive tract. For patients with severe bleeding during the acute attack, they should abstain from eating and drinking, which means that patients should not eat or drink anything, so as to control the bleeding of the gastrointestinal tract, avoid mechanical and chemical stimulation, and allow the gastrointestinal tract to recover. For the recovery period when bleeding stops, patients should eat a liquid or semi-liquid diet, give a diet with less residue and no stimulation, and eat more vegetable puree, fruit puree, steamed meatballs, and steamed fish balls, honey, etc. This has a certain protective effect on the patient’s gastrointestinal tract and prevents rebleeding.
