WHAT IS STOMACH ULCER?

Ulcers are sores on the lining of your stomach or small intestine. They occur when the protective mucus that lines the stomach becomes ineffective. The stomach produces a strong acid to help digest food and protect against microbes. To protect the tissues of the body from this acid, it also secretes a thick layer of mucus. If the mucus layer is worn away and stops functioning effectively, the acid can damage the stomach tissue, causing an ulcer. Stomach ulcers are relatively easy to cure, but they can cause significant problems if left untreated.
