Stomach pain when pressed may be caused by chronic gastritis, gastric ulcer, gastric neurosis and other reasons. 1. Chronic gastritis: chronic gastritis may be caused by Helicobacter pylori infection, long-term use of non-steroidal anti-inflammatory drugs and other reasons. Patients will have hidden pain in the upper abdomen, loss of appetite, fullness after meals, acid reflux, nausea and other manifestations. If the patient’s stomach is pressed, it may cause pain. 2. Gastric ulcer: Gastric ulcer is mainly caused by Helicobacter pylori infection. Patients often manifest stomach pain, fullness after meals, loss of appetite and so on. If the patient’s stomach is pressed, it may aggravate the stimulation of the stomach, and the symptoms of pain may easily appear. 3. Gastric neurosis: the etiology of gastric neurosis is still unclear, and it is considered to be caused by psychosomatic disorders, heredity, and abnormal autonomic function. Patients may also have epigastric pain, epigastric burning sensation, abdominal distension and other manifestations. Therefore, patients presenting with gastric neurosis will feel pain when pressure is applied to the stomach. There are many other factors that cause stomach pain when pressed, so patients are advised to consult a doctor in time to get a clear diagnosis and then treat the cause.
