Name given to the presence of deformities in the form of pouches that develop in the walls of the colon or large intestine, commonly as a consequence of chronic constipation. The symptoms generally include pain and inflammation in the lower half of the abdomen, usually accompanied by constipation, and can be confused with colitis symptoms. These deformities can present severe complications, including inflammation, hemorrhage, and even perforation of the intestine walls, which can call for hospital use and surgery.
