Ask a question


A stomach disease is any disorder of this organ, which plays a major role in the digestion of food. Among the most common diseases are inflammation of the stomach lining (gastritis) that can be acute but more often chronic, a stomach ulcer which is a highly localized destruction of the stomach wall which can cause a perforation, and also different kinds of gastric cancer. The main symptom of stomach disease is a pronounced pain in the epigastric region, in the central and upper part of the abdomen. Frequently, too much stomach acid causes pain after eating with a feeling of acid reflux. The stomach can be studied through an endoscopic examination called a gastroscopy.
