Three examples of colon disease are colitis, diverticulosis and colon polyps, according to MedlinePlus. The colon is also known as the large intestine. The colon is the part of the intestine that makes and stores fecal waste.
Colitis is the overall name for inflammatory bowel diseases. Crohn's disease and ulcerative colitis are two similar but distinctly different diseases within the colitis diagnosis. Crohn's disease affects the entire colon and sometimes the small intestines as well, according to MUSC Digestive Disease Center. Ulcers develop within the intestines with Crohn's disease, and bowel obstruction is one complication of the disease. Ulcerative colitis affects the superficial portion of the colon lining. Symptoms of colitis include rectal bleeding, abdominal pain and severe diarrhea.
Diverticulosis involves the development of small, sac-like structures in colon. Diverticulosis is an age-related disease. By age 60, one-third of people may develop the condition, states an article reported by Harvard Medical School. The number increases to two-thirds by age 85. Symptoms of diverticulosis include abdominal cramps and bleeding.
Colon polyps are extra growths of tissue in the large intestine. Age and family history are the most significant risk factors, lists MedlinePlus. The greatest danger that colon polyps pose is the possibility of development of cancer.
