When an ulcer spreads to other nearby organs or tissues it is called a penetrating ulcer. These two types of ulcers are severe and life threatening if they are not treated. Normally, food is broken down into small particles by the acid produced in your stomach. An ulcer occurs when this acid also breaks down the wall of the intestines or stomach. This can happen when the stomach makes too much acid or when the protective mucus lining of the stomach and intestines is reduced.
Ulcers can develop slowly for months or rapidly in a few days.
When an ulcer worsens, it can penetrate into organs such as the pancreas and liver, or into the abdominal wall. Ulcer complications can be emergencies. Your health care provider will ask about your symptoms and do a physical exam, especially of your abdomen. If the ulcer has made a hole all the way through the tissue, it causes bleeding inside the abdomen. If you are bleeding inside, you will be hospitalized and given emergency treatment for blood loss.
