[Effects of overweight and obesity on symptoms, overall condition and quality of life in patients with fibromyalgia syndrome].

Compared with normal-weight FMS patients, overweight/obesity patients have higher levels of perceived stress, lower sleep efficiency, and more severe fibromyalgia symptoms, as well as a low quality of life characterized by decreased physiological function. It is important for overweight/obesity FMS patients to control BMI actively in order to improve sleep efficiency, psychological state, physical functioning, and the overall condition.
