How do the organs get infected with Crohns disease?

Answer 1

Crohn's disease can affect the small and large intestine as well as other organs in the digestive tract. The doctors will tell you after the diagnosis "from mouth to anus and everything in between" Unlike ulcerative colitis, which only affects the inner layer of the bowel, Crohn's disease commonly involves all layers of the intestinal wall.

One thing that causes complications to other internal organs are Fistulas which can connect between two separate organs. Fistulas may connect the intestine and bladder or the intestine and the skin surface, especially around the anus. Although fistulas from the small intestine are common, wide-open holes (perforations) are rare but happen. Occasionally a fistula forms an abscess, or collection of pus, near the intestine and close to another organ. This is a pocket of infection that requires drainage either through a catheter inserted by a radiologist or a special drain that is surgically inserted. The areas around the anus and rectum are often involved in this fashion. In addition to fistulas, cracks or fissures may also develop in the lining of the mucus membrane of the anus.
