Frequent stomach pain may be caused by improper diet, indigestion, gastritis, gastric ulcer and so on. 1. Improper diet: when patients consume spicy, stimulating, greasy, too cold, too hot and other foods, it will stimulate the gastrointestinal mucosa, causing damage to the gastrointestinal mucosa, leading to the occurrence of stomach pain symptoms. 2. Dyspepsia: When patients suffer from dyspepsia, the food in the gastrointestinal tract undergoes abnormal fermentation and produces a large amount of gas, which can cause bloating and pain in the stomach. 3. Gastritis: When gastritis occurs in patients, the gastric mucosa is damaged, and when the gastric mucosa is stimulated, spasms will occur, triggering the symptoms of stomach pain. 4. Gastric ulcer: when the patient has gastric ulcer, the gastric acid secretion is too much, the ulcer surface is stimulated by the gastric acid to produce pain, and the pain often occurs after meals. When stomach pain occurs, it is best to go to the hospital in time for examination. If the above diseases occur, please follow the doctor’s advice for treatment.
