A evaluation revealed in March 2017 within the journal Intestine and Liver discovered that 4 to 78 p.c of individuals with IBS additionally had SIBO.

There’s additionally proof that folks with IBS are likely to endure from temper problems akin to despair or nervousness. “There’s a excessive overlap between the 2,” says Jeffrey Baumgardner, MD, a gastroenterologist in Santa Rosa, California. “A major variety of folks with IBS even have a historical past of some sort of abuse — emotional, bodily, or sexual.”
Dr. Baumgardner additionally thinks that IBS has one thing to do with how folks course of stress, although analysis hasn’t proven why but.
