IBD Raises Asthma Risk

NOVEMBER 01, 2005

The results of a large study showed that asthma is more prevalent in individuals with inflammatory bowel disease (IBD), such as ulcerative colitis and Crohn's disease. In the first study to uncover an association with asthma, the researchers looked at 8072 patients with IBD and compared them with a control group matched by age, sex, and geography.

As reported in Gastroenterology (September 2005), the researchers learned that patients with ulcerative colitis were 1.5 to 1.7 times more prone to have asthma, compared with the control group, and patients with Crohn's disease had a 1.3 to 1.4 times greater risk.
