Stomach pain from pressure is associated with chronic gastritis, gastric ulcer, and gastric cancer. When the protective barrier of gastric mucosa is damaged, the gastric mucosa will become painful when it comes into contact with acidic food due to stimulation. Patients with more pronounced pain on compression need to be alert to gastric ulcer, which is more intense and has a certain regularity, mainly about an hour after meals. Some people have pain in the stomach when pressing, and at the same time, they can also feel a swelling. For people whose pain lasts longer, they should promptly undergo gastroscopy to avoid being caused by gastric cancer.
