Chronic fatigue syndrome shares risk markers with IBS

Chronic fatigue syndrome (CFS) and irritable bowel syndromes (IBS) share the same predisposing markers, but triggering markers differ, a new study by UK researchers has found.

Researchers matched 4,400 patients with any fatigue syndrome to two groups of patients: those attending for IBS and those attending for any other reason.

Infections were specific risk markers for both syndromes. Viral infections increased the risk of a fatigue syndrome by 2.3 times compared to patients attending for any other reason, and gastroenteritis increased the risk of IBS by 1.5 times compared to a fatigue syndrome.
