Diverticulosis and diverticulitis. In diverticulosis, which is common in older people, small sacs form on the wall of the large intestine. Although they usually cause no symptoms, occasionally there is pain in the lower side of the abdomen. Treatment includes a diet high in fiber and liquids. Diverticulitis develops after the sacs become inflamed and causes a fever.
Treatment consists of bed rest and antibiotics.
Sometimes symptoms such as pain, diarrhea, constipation, bloating, and gas are caused by a functional disorder such as irritable bowel syndrome. In these disorders there are no signs of disease and yet the intestinal tract still fails to work properly. A functional disorder may cause discomfort, but it is unlikely to lead to a serious disease. A doctor may prescribe medication to relieve symptoms. Because diet and stress are thought to trigger functional disorders, the same guidelines that help to keep your system running smoothly should help control the symptoms.
