Diverticulitis is the inflammation of small, protruding pouches called diverticula which can develop in any part of the gastrointestinal tract. Diverticula commonly develop after the age of 40 and occurs most often in the large intestine. The presence of diverticula in the digestive system is referred to as diverticulosis and may not cause any problems. But when these pouches become infected and inflamed symptoms are experienced.
The sudden onset of severe pain in the lower left sign of the abdomen is a symptom of diverticulitis. Less often, the pain may initially be mild in intensity but worsen over several days. A person may also experience a fluctuation in the intensity of the pain. In addition to abdominal pain, a person will notice a change in bowel habits, such as the onset of constipation or diarrhea. Other signs are nausea, vomiting, fever, and chills. Rarely, bleeding can occur and will be noted in the stool or in the toilet upon defecating.
Diverticula form in the areas of the intestine which are naturally weak and are under pressure. Medical experts believe that one risk factor is age. As we age, the strength and elasticity of the intestinal lining weakens. Though not clearly understood, the experts link a lack of exercise to the development of diverticula. Another risk factor for diverticular disease is low fiber in the diet. Obesity increases the risk of developing diverticulitis and the complication of rectal bleeding.
The cause of inflammation of diverticula is unclear. One thought is that increased pressure in the colon weakens the walls of the diverticula and increasing the risk of an infection. Fecal matter may become get caught in the narrow openings of the diverticula and an infection develops. Any blockage of the narrow opening of a diverticula can reduce the blood supply and cause inflammation.
It is the symptom of abdominal pain during an acute attack of diverticulitis that makes a person seek medical attention. Since abdominal pain is associated with other causes such as appendicitis, irritable bowel syndrome, and colon cancer, several tests are necessary to make the proper diagnosis.
