The causes of stomach problems are drug and alcohol stimulation, stress effects, H. pylori infection, bad emotions and daily living habits. Taking too much drugs that hurt the stomach can lead to serious damage to the gastric mucosa, alcohol can easily stimulate the stomach with nausea, vomiting and regurgitation, which can also cause gastric mucosal congestion or even gastric perforation, and stress caused by severe traumatic stimulation or surgery can also lead to gastric disease. Unhygienic diet and cross-infection can lead to the appearance of H. pylori, which causes inflammation by repeated infection in the gastric sinus, causing the loss of the protective mucosa of the stomach and eventually stomach discomfort. In addition, excessive mental stress, prolonged emotional depression, poor dietary habits, overeating, and a preference for cold, raw and stimulating foods can also lead to serious gastric disorders.
