Women after the menopause appear to be more susceptible to sleep related breathing disorders (SBDs). The increased prevalence of SBDs in postmenopausal women may be related to weight gain and the decline in female sex hormones levels. These conditions may cause upper airway obstruction, which can result in sleep disruption. Other sleep disorders, such as insomnia, depression, and fibromyalgia must be ruled out with SBDs in postmenopausal women with sleep difficulties. Once SBD is strongly suspected through medical history and precise physical examinations, polysomnogram is required for confirmatory diagnosis. In addition, other examinations besides polysomnogram should be performed to detect obstructed regions. Treatment of SBD can be classified into surgical method and non-surgical method. Treatment options must be carefully selected by considering the patient's clinical examinations, patient's preference, age and life style.
