Diverticulosis is a condition when the colon develops weak spots and small bulges occur. These spots are called diverticula and when the diverticula gets inflamed or infected, it is called diverticulitus. Diverticulosis affects about 10-25 percent of people with diverticulosis. 

The cause of diverticulosis is often believed to be a low fiber diet. A low fiber diet makes stool harder to pass through and therefore it causes increased pressure in the colon. This pressure causes the weak spots to bulge forming the diverticula.

There may or may not be symptoms of diverticulosis. Symptoms of diverticulosis may include:

* Abdominal pain on the lower left hand side that can vary from mild to severe.

* Fever and chills

* Rectal bleeding

* Nausea and vomiting

The infection inside the colon can vary from a minor inflammation or a major infection. If it is not treated, complications will arise from diverticulitis and these complications include:

* Abscesses can be formed because of the infected contents of the pouch

* Perforation of the pouch, which will cause intestinal waste to leak into the abdominal cavity

* Peritonitis can occur if the infection spreads to the peritoneal cavity

* Fistulas may occur

* Intestinal obstruction
Depending on the severity of the attack, treatment for diverticulitis can vary from liquid diet will help allow the colon to heal while fruits, vegetables and whole grains are avoided, to hospitalization and possibly surgery. Surgery for diverticulitis consists of partial removal and resectioning of the colon.

Diverticulitis is a condition that can be prevented by following a high fiber diet that includes fruits, vegetables and whole grains. You should aim to have 25 grams of fiber in your diet every day. Popcorn, seeds, and peanuts can get stuck in one of the pouches and should be avoided. Fatty foods should also be avoided and you should make sure that you drink a lot of water. A good exercise program will also be helpful.

If you experience any symptoms of diverticulitus, see your doctor for proper treatment.
