It's unclear. Some older studies have found a link between psychiatric conditions and IBD conditions like Crohn's disease and ulcerative colitis. But the exact nature of this association remains a controversy. Some researchers question the validity of these findings, while other researchers consider the link to be proven.
More recent research suggests that a depressed mood and an increased anxiety level have a negative effect on the course of IBD. Patients who exhibit symptoms of depression and anxiety report a lower quality of life and may be at increased risk for a relapse. One study showed that patients with Crohn’s disease who received some psychological treatment spent fewer days in the hospital and took fewer sick days.
If You Think You’re Depressed…
While the jury is still out on exactly how mood affects IBD, and if IBD and depression are related, there is no question that identifying and treating depression and anxiety is important to overall health.
Diagnosing depression typically begins by ruling out any physical conditions that could cause the symptoms. The first step includes a check-up with a primary care physician or internist, or a gastroenterologist. A complete history with a focus on the length and severity of any symptoms of depression (described below) will be included. A referral to a mental health specialist may be necessary for proper diagnosis and treatment.
Treatment is highly individualized, and may include a combination of psychotherapy, medications and complementary treatments.
