In both Crohn's disease and ulcerative colitis the basic maintenance medication are the 5-ASA products. Corticosteroids are used in medium to severe cases, however long-term corticosteroid use is not recommended. If corticosteroids are of no help, immunosuppressive medication may be needed.
Most medications used for IBD do not have side effects that affect your ability to exercise. Corticosteroids are an exception. They cause fluid retention and, in large doses, cause visible muscle loss. They also may slow down the healing process of overuse injuries.
For professional athletes, it may be important to know that according to the 2005 Prohibited List by the World Anti-Doping Agency, all glucocorticosteroids are prohibited when administered orally, rectally, intravenously or intramuscularly. The use of, for example, oral glucocorticosteroids or enemas requires a Therapeutic Use Exemption approval and the use of local glucocorticosteroids, such as inhalers or eye drops, requires an Abbreviated Use Exemption approval. In other words, in case the treatment of your illness requires corticosteroids, you can get a special approval. Most other medicines used for IBD are not prohibited, but you should always consult your doctor and coach to avoid unexpected situations.<?xml:namespace prefix = o />
