Inflammatory bowel disease (IBD) is an umbrella term used to describe disorders that involve chronic inflammation of your digestive tract. ypes of IBD include:
Both ulcerative colitis and Crohn's disease usually are characterized by diarrhea, rectal bleeding, abdominal pain, fatigue and weight loss.
IBD can be debilitating and sometimes leads to life-threatening complications.
Inflammatory bowel disease symptoms vary, depending on the severity of inflammation and where it occurs. Symptoms may range from mild to severe. You are likely to have periods of active illness followed by periods of remission.
Signs and symptoms that are common to both Crohn's disease and ulcerative colitis include:
See your doctor if you experience a persistent change in your bowel habits or if you have any of the signs and symptoms of inflammatory bowel disease. Although inflammatory bowel disease usually isn't fatal, it's a serious disease that, in some cases, may cause life-threatening complications.
The exact cause of inflammatory bowel disease remains unknown. Previously, diet and stress were suspected, but now doctors know that these factors may aggravate but aren't the cause of IBD.
One possible cause is an immune system malfunction. When your immune system tries to fight off an invading virus or bacterium, an abnormal immune response causes the immune system to attack the cells in the digestive tract, too. Heredity also seems to play a role in that IBD is more common in people who have family members with the disease. However, most people with IBD don't have this family history.
Cigarette smoking. Cigarette smoking is the most important controllable risk factor for developing Crohn's disease.
Smoking may help prevent ulcerative colitis. However, its harm to overall health outweighs any benefit, and quitting smoking can improve the general health of your digestive tract, as well as provide many other health benefits.
Ulcerative colitis and Crohn's disease have some complications in common and others that are specific to each condition. Complications found in both conditions may include:
