More than 6.8 million people worldwide are estimated to be living with inflammatory bowel disease (IBD). IBD is believed to be the result of a malfunctioning immune system, which results in an inappropriate immune response that attacks the lining of the intestines.

There is no cure and no exact cause, though researchers continue to look at how genes, the microbiome and environmental factors play a role in this chronic disease. Dr. Amanda Johnson, a Mayo Clinic gastroenterologist, helps us better understand IBD and whether diet can help.
