Gastric problems may be caused by bad habits, dietary factors, medication factors, Helicobacter pylori (Hp) infection and so on. 1. Bad life habits: long-term heavy drinking and smoking. Ethanol is lipophilic, which can lead to gastric mucosal erosion and mucosal bleeding. Tobacco can also damage the gastric mucosa, leading to gastritis. 2. Diet: Eating cold, spicy and irritating food and dry and hard food can lead to gastric mucous membrane damage, gastritis, gastric ulcer and gastric bleeding and other diseases. 3. Drugs: long-term use of non-steroidal anti-inflammatory drugs, such as aspirin, can inhibit the generation of COX-1 (cyclo-oxygenase), resulting in the maintenance of normal regeneration of the mucosa of the prostaglandin E insufficient mucosal repair obstacles to the emergence of gastric erosion and bleeding. 4. Infection of Helicobacter pylori: By virtue of the ammonia and vacuolar toxin it produces, Helicobacter pylori causes cellular damage and promotes the release of inflammatory mediators from epithelial cells, leading to gastritis. If the patient has gastric disease, he should go to the hospital in time and standardize the treatment under the guidance of the doctor.
