Inflammatory bowel disease

Inflammatory bowel disease takes two forms: ulcerative colitis and Crohn's disease, both of which are more virulent than irritable bowel syndrome (IBS), with which the disease is sometimes confused. After a sufficient period, it is possible to clearly diagnose the disease. Parts of the intestine become inflamed and food may not be absorbed properly. Sometimes the diseased part of the bowel is surgically removed. The causes of the disease are not known, but there may be a genetic predisposition to Crohn's disease. In addition, diet and emotions, such as anxiety and feelings of stress have been weakly linked to the disease.
Inflammatory bowel disease is much less common than IBS, which shares some of the same early symptoms. Inflammatory bowel disease affects women and men equally often.
