Their cause is still unclear. These conditions cause an immune reaction in which the body detects different parts of the digestive tract, depending on the condition, as foreign. The intestine presents an inflammatory reaction seen in the internal walls as swelling, as well as in ulcers with high risk of bleeding. Symptoms include frequent diarrhea, which might include mucous and fresh blood, weight loss, and anemia. If the conditions continue in their progress, they may result in colon cancer.
It is important to undergo a colonoscopy to obtain tissue samples through biopsies that will provide a specific diagnosis. With the proper treatment, it is possible to regain the function of the colon and remain without symptoms for long periods of time.
