Certain blood and stool tests are performed to arrive at a diagnosis. The disorder often remains quiet and easily controlled for long periods of time. Most people with Crohn's disease continue to pursue their goals in life, go to school, marry, have a family, and work with few limitations or inconveniences. Some problems, outside the bowel, can occur. As noted, the disease can occur around the anal canal.
Open sores called fissures can develop, which are often painful.
A fistula can also form. This is a tiny channel that burrows from the rectum to the skin around the anus. In addition, when inflammation persists in the ileum or colon, narrowing and partial obstruction may occur. Surgery is usually required to treat this problem. When Crohn's disease has been present for many years there is an increased risk of cancer.
