Diverticulosis is the formation of numerous tiny, small pockets and multiple pouches in the digestive tract which are not inflamed. These pockets are called diverticula. However, when the pockets or pouches become inflamed, the condition becomes diverticulitis. Diverticula  usually develops at the weak points of either the large or small intestine walls. However, most of it forms in the large intestine, and the most common is the sigmoid colon . Persons with this condition are usually asymptomatic. However, when there are symptoms, the following occur:
- Lower abdominal cramping
More serious cases are characterized by abscess, perforation, fistula, and obstruction. Treatments range from the use of antibiotics to hospitalization and/or surgery.
