What is Peptic Ulcer?
A peptic ulcer is a sore that develops on the lining of the stomach or the upper part of the small intestine, a region known as the duodenum. Ulcers occur when the lining in these regions breaks, exposing the underlying tissues to stomach acids and enzymes. They are a very common condition, affecting approximately 10 percent of all Americans at some point in their lives. Although stress and diet are sometimes thought of as contributing to the development of ulcers, research suggests that this is not the case. So what causes ulcers?
