<unk>  in the sigmoid colon of a . Some people with<unk>  complain of symptoms such as cramping, bloating, flatulence, and irregular defecation. However, it is unclear if these symptoms are attributable to the underlying<unk>  or to coexistent irritable bowel syndrome. Diverticular disease was found associated with a higher risk of left sided colon cancer. Bleeding Diverticular disease can present with painless rectal bleeding as bright red blood per rectum. Diverticular bleeding is the most common cause of acute lower gastrointestinal bleeding. However, it is estimated that 80% of these cases are self-limiting and require no specific therapy. Diverticulitis Infection of a diverticulum can result in diverticulitis. A recent study found that it happens only about 4% of the time. That contradicts the prevailing thinking that 10% to 25% of people with<unk>  go on to develop diverticulitis. Tears in the colon leading to bleeding or perforations may occur; intestinal obstruction may occur (constipation or diarrhea does not rule this possibility out); and peritonitis, abscess formation, retroperitoneal fibrosis, sepsis, and fistula formation are also possible occurrences. Rarely, an enterolith may form. Infection of a diverticulum often occurs as a result of stool collecting in a diverticulum. It is defined as diverticular disease with signs and symptoms of diverticular inflammation. Clinical features of acute diverticulitis include constant abdominal pain, localized abdominal tenderness in the left lower quadrant of the abdomen, nausea, vomiting, constipation or diarrhea, fever and leukocytosis. Most people with colonic<unk>  are unaware of this structural change. When symptoms do appear in a person over 40 years of age it is important to obtain medical advice and exclude more dangerous conditions such as cancer of the colon or rectum. Segmental colitis associated with<unk>  Segmental colitis associated with<unk>  (SCAD) is a condition characterized by localized inflammation of the colon between diverticula (interdiverticular mucosa) while sparing the diverticular orifices. SCAD may lead to abdominal pain, especially in the left lower quadrant, intermittent rectal bleeding, and chronic diarrhea.
