K65.9: Peritonitis, unspecified

You have an inflammation in your abdomen.

The abdominal organs are located in the abdomen. The abdomen is lined from within with a membrane. The membrane is made up of individual cells. These cells normally release a small amount of fluid into the abdomen. Thanks to this fluid, the organs can move and slide past each other.

The membrane around your abdominal organs has become inflamed. Because of the inflammation, you may have severe pain. You may also need to vomit or have a fever.

The membrane around the abdominal organs may become inflamed for instance when bacteria from the digestive organs or sex organs get into the abdomen. That may occur for instance when the gallbladder or intestines are inflamed. The bacteria can then get into the abdomen through small tears in the wall of the gallbladder or the wall of the intestines.
