Fatigue is one of the most prevalent symptoms occurring in peri- and postmenopausal women. It is strongly associated with reduced quality of life in this population. Studies have shown a strong association between fatigue and menopausal symptoms such as hot flashes, vaginal symptoms, and sexual dysfunction. Because sleep disturbance commonly co-occurs in women with hot flashes as a result of nocturnal hot flashes disrupting sleep, sleep disturbance may explain the association between hot flashes and fatigue in this population. However evidence suggests that fatigue can occur in the absence of sleep disruption, indicating that sleep problems do not exclusively explain the etiology of fatigue in this population.
