Stomach ulcers, also known as gastric ulcer or peltic ulcer, is a lesion that forms in the lining of the stomach.
Doctors used to believe that stressful lifestyle and poor diet caused ulcers. Later, it was discovered that an off-balance between digestive fluids (hydrochloric acid and pepsin) resulted in ulcers. Today, research shows that most ulcers develop as a result of infection with a spiral-shaped bacterium found in the stomach called Helicobacter pylori (H. pylori). The bacteria can also attach to stomach cells, further weakening the stomach’s defensive mechanisms. For reasons not completely understood, H. pylori can also stimulate the production of acid in the stomach and cause tissue damage and inflammation, which may finally result in an ulcer.
Stomach ulcer causes burning sensations in the abdomen behind the breastbone which can be especially painful when the stomach is empty.
