Inflammatory Bowel Disease - Ulcerative Colitis
After you swallow food, it moves through your esophagus and into your stomach. Chemicals in your stomach break down the food into a liquid form. The processed liquid travels from your stomach to your small intestine. Your small intestine breaks down the liquid even further so that your body can absorb the nutrients from the food you ate. The remaining waste products from the small intestine travel to the large intestine.
Your large intestine, also called the large bowel or colon, is a tube that is about 5 feet long and 3 or 4 inches around. The lower GI tract is divided into sections, including the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anal canal, and anus. The appendix is located on the cecum, but it does not serve a purpose in the digestive process.
The first part of the colon absorbs water and nutrients from the waste products that come from the small intestine. As the colon absorbs water from the waste product, the product becomes more solid and forms a stool. The large intestine moves the stool into the sigmoid colon, where it may be stored before being traveling to the rectum.
The cause of ulcerative colitis is unknown. Researchers suspect that in select people, the immune system overreacts to normal bacteria in the intestine and causes inflammation. Further, researchers suspect that bacterial or viral diseases may contribute to the development of ulcerative colitis.
Am I at Risk
Because the cause of ulcerative colitis is unknown, specific risk factors are difficult to identify. It appears that ulcerative colitis may have an inherited component in select families. It appears to occur more frequently in people of Jewish ancestry and less commonly in African Americans. You should tell your doctor about your possible risk factors and discuss your concerns.
