What is Sigmoid Colon Diverticulitis?

To understand Sigmoid Colon Diverticulitis, it is extremely important to know what is diverticula.

Diverticula are small bulging pouches that tend to form in the lining of the digestive tract. These diverticula are mostly formed in the lower part of the large intestine which is also called as colon. The colon is divided into four categories which are the ascending colon, the descending colon, the transverse colon, and the sigmoid colon. Generally, diverticula can form in any of these parts of colons but they are usually formed in the sigmoid colon. Diverticula as a single entity is usually harmless until they become infected and result in a pathological condition called as diverticulitis.

An infected diverticula in the sigmoid colon is referred to as Sigmoid Colon Diverticulitis. Sigmoid Colon Diverticulitis can result in severe abdominal pain, fever, nausea, and substantial change in the bowel patterns. Mild forms of Sigmoid Colon Diverticulitis can be treated just with rest, dietary changes and antibiotics but advanced or severe forms of Sigmoid Colon Diverticulitis need to be treated with surgery.
