Fibromyalgia and irritable bowel syndrome are both common conditions w
hich account for most of the referrals to physical medicine and rehabi
litation-rheumatology and gastroenterology clinics, and they frequentl
y coexist. In this study, we utilized a previously validated questionn
aire to assess the prevalence of symptoms of bowel dysfunction and irr
itable bowel syndrome, and to survey the range of bowel pattern in 75
patients with fibromyalgia as compared to 50 normal controls. Symptoms
associated with irritable bowel syndrome (p < 0.05) were reported in
41.8% of the fibromyalgia patients and 16% of the normal controls, In
conclusion, we found that patients with fibromyalgia have a high preva
lence of gastrointestinal complaints confirming the results indicating
that fibromyalgia and irritable bowel syndrome frequently coexist, Th
is may suggest a common pathogenic mechanism for both conditions.
