Why is Maintenance Therapy Needed in IBD?
The term "maintenance therapy" refers to the various kinds of treatment (usually medical) given to patients to enable them to maintain their health in a disease-free, or limited-disease, state. If you have been diagnosed with Crohn's disease or ulcerative colitis, the first goal of treatment is for you to get better (a stage in the illness known as going into "remission"). The next challenge is to keep you in remission. The treatments used for this second step are referred to as "maintenance therapies."
