Gastrointestinal bleeding patients’ dietary contraindications are as follows: 1, prohibit alcohol: alcohol produces direct stimulation of the gastric mucosa, easily inducing gastrointestinal bleeding, aggravating cirrhosis, worsening the primary disease and making bleeding difficult to cure; 2, quit smoking: cigarettes contain nicotine, which can produce some stimulation of the gastrointestinal tract and easily induce bleeding; 3, prohibit stimulating foods, such as ginger, garlic, vinegar, onion, seafood, fried foods, which are not conducive to healing of gastrointestinal bleeding. Avoid drinking carbonated beverages such as cola and Sprite, which may lead to symptoms such as burping and flatulence, which are not conducive to the control of bleeding; 4. Strict fasting is required during gastrointestinal hemorrhage, and a full liquid diet, such as rice soup and milk, is consumed after the bleeding stops, and gradually transitions to a semi-liquid diet, such as thin rice and noodles, and then transitions to soft rice and rice, and eventually resumes a normal diet as the condition improves.
