Crohn's Disease and its 10 Manifestations

8. Arthritis

Another common extraintestinal symptom of Crohn's disease is arthritis. Some studies suggest that arthritis affects nearly 30 percent of people with Crohn's disease. It is difficult for doctors to properly link arthritis to inflammatory bowel diseases. Generally, because the arthritis is a complication of inflammation in the gastrointestinal tract, it is less severe than other forms of arthritis. The joints do not suffer odd damage or destructive changes, and the symptoms generally improve following treatment for the underlying condition.
