The most effective measures to nourish the stomach and intestines need to be based on specific gastrointestinal problems. Gastrointestinal problems can be categorized into functional and organic. Functional problems are mainly treated with conditioning; organic problems need to be considered for medication (e.g., omeprazole, mesalazine) or even surgical treatment. 1. Functional problems: regulation includes dietary structure, eating habits, exercise, emotions, work and rest, defecation habits, etc. Dietary structure: meat and vegetables, avoid spicy and stimulating food. Eating should be chewed slowly, avoid overeating. Exercise: Moderate aerobic exercise helps to recover gastrointestinal function and also improves physical fitness. It can also improve the mood: anxiety, depression and other emotions can reduce the digestive ability; rest and relaxation: good rest and relaxation habits can help the recovery of gastrointestinal peristaltic rhythm; defecation habits: adhere to regular defecation, which can help the intestinal tract to empty and reduce the absorption of toxic substances in the feces. 2. Organic problems: such as gastritis, gastric ulcer need to consider omeprazole, domperidone and other drugs; ulcerative colitis, Crohn’s disease, etc. need to consider the mesalazine, luzosulfapyridine and other drugs; gastrointestinal polyps and tumors need to be considered for surgical treatment. For the measures to support the stomach and intestines, it is recommended to visit the doctor to give treatment according to the individual situation, and the drugs are taken in accordance with the doctor’s instructions.
