Ulcers are sores or lesions in your stomach or the upper part of your small intestines. Ulcers develop when the acids that digest foods damage the stomach or intestinal walls. Connected to a variety of causes like stress, diet, and lifestyle, scientists now know that many ulcers are caused by a type of bacteria called Helicobacter pylori, or H. pylori. Left untreated, most ulcers will continue to get worse, so it's important to receive a proper diagnosis and make the dietary and lifestyle changes that will allow you to heal fully.
