Overview
Diverticulitis is a common digestive disease particularly found in the colon (the large intestine).[1] Diverticulitis develops from diverticulosis, which involves the formation of pouches (diverticula) on the outside of the colon. Diverticulitis results if one of these diverticula becomes inflamed or infected.[2] The colon can become infected with craters of food stuck inside, which causes abdominal pain.

History and Symptoms
When taking a medical history, the doctor may ask about bowel habits, pain, other symptoms, diet, and medications. The physical exam usually involves a digital rectal exam. To perform this test, the doctor inserts a gloved, lubricated finger into the rectum to detect tenderness, blockage, or blood. The doctor may check stool for signs of bleeding and test blood for signs of infection.
Physical Examination
Diverticulitis diagnosis depends on taking a proper history and doing physical examination. The known diagnostic criteria for diverticulitis includes abdominal tenderness especially in the left lower quadrant, leukocytosis and CT scan findings helps in disease confirmation. Fever is common in diverticulitis patients. Abdominal examination will reveal tenderness, decreased bowel sounds and palpable mass may be felt. In some patients, genitourinary signs of cystitis would occur due to bladder irritation.[3]
