Usually, pressing the stomach will hurt may be due to gastric ulcer, chronic gastritis, cholecystitis and so on. 1. Gastric ulcer: When the gastric mucosa is broken for some reason, ulcers are likely to occur in this area, i.e. gastric ulcer. When pressed, the stomach will increase internal pressure due to the increase in external pressure, resulting in stomach pain at the site of gastric ulcer. 2. Chronic gastritis: Patients with chronic gastritis will have excessive secretion of gastric acid. When pressing the stomach, the gastric mucosa will come into contact with gastric acid, which will lead to pain. 3. Cholecystitis: If there is a bacterial infection, germs will go backward from the biliary tract to the gallbladder, resulting in poor bile flow and cholecystitis. Since the gallbladder and stomach belong to the same sensory nerve innervation, when pressing the stomach it may cause cholecystitis to attack and radioactive pain to appear around it, thus leading to the symptom of stomach pain. Pressing on the stomach pain may also be associated with other causes. It should be noted that if the patient has the above situation, it is recommended to go to the hospital in time to clarify the cause of the disease under the guidance of a professional physician.
