Drinking milk can nourish your stomach, but you can't drink milk when you have a stomachache. Once you have a stomachache, you should pay more attention to your diet, and you should improve it with a "mild diet" that is non-irritating, low-fiber and easy to digest, and has enough nutrients: you can eat mild and easy-to-digest starchy foods such as porridge. Eat processed soy products such as soymilk, tofu, dried soybeans, and soymilk flowers. Eat vegetables that are low in fiber. Eat fruits that are low in sweetness and fiber Avoid indigestible food groups such as glutinous rice. Avoid stimulating condiments. For snacks, choose soda crackers. It is better not to eat red bean soup or green bean soup. You can eat some drugs to protect the gastric mucosa, such as Tai Gumi, while adding gastric acid inhibiting drugs. But the most important thing is to nourish the stomach in general. Three meals at regular intervals, should not be too full, avoid spicy food. With the protection and enhancement of gastric mucosal defense function of a class of drugs collectively known as gastric mucosal protective agent. Commonly used gastric mucosal protective agents are colloidal sub rafter acid button (such as Deno or Delo), aluminum sulfate, gastric membrane, baobab tablets, Mazurin S, prostaglandins and so on. Dysentery also has the effect of enhancing the gastric mucosal barrier, and there are also some antacids, such as Gastrobiocide and Ledgastrin, which also have the effect of improving the protection of the gastric mucosa. At present, gastric mucosal protective agents have become the main drugs for the treatment of gastric ulcer. Magnesium aluminum carbonate, as a kind of active aluminum agent, is a commonly used mucosal protective agent. It has a unique laminar network lattice structure, deposited on the mucosal surface of the upper gastrointestinal tract to form a protective layer, blocking the damage factor in the gastric lumen; the laminar network lattice can be used as a HCO3-storage pool to enhance the mucus bicarbonate barrier. Magnesium aluminum carbonate can up-regulate the expression of epidermal growth factor (EGF) and its receptor in damaged tissues to promote the repair of epithelial layer, and can also up-regulate the expression of fibroblast growth factor (bFGF) and its receptor to promote the neovascularization of granulation tissue at the bottom of the ulcer, to promote the production of prostaglandins, dilate the gastric mucosal microvessels, and to improve the blood flow of the gastric mucosa. Magnesium aluminum carbonate has an enhanced effect on all levels of the defense and repair system, not only plays the role of the protective layer, but also promotes the repair of damaged tissues, which is a comprehensive gastric mucosal protection agent.
