Condition Overview

Inflammatory bowel disease (IBD) is a group of autoimmune conditions, including Crohn’s disease, ulcerative colitis and other inflammatory conditions of the colon and small intestine. Altogether, about 1.6 million Americans are affected.

The cause of IBD is not well understood but genetics and diet are factors. The microbiome of the digestive tracts also seems to be involved.

Symptoms include abdominal pain, vomiting, diarrhea, rectal bleeding, severe internal cramps or muscle spasms in the region of the pelvis and weight loss.

Conventional treatment usually involves anti-inflammatory drugs or antibiotics. Extreme cases may require surgery.

IBD is a lifelong condition without a cure, but remission is possible with successful treatment.

Interesting Fact

A 2014 survey of IBD patients found that, of those who were users, a majority reported that marijuana was “‘very helpful’ for relief of abdominal pain, nausea, diarrhea.” Of those who were not marijuana users, half reported an interest in trying it if it was legal in their state.
