The first signs of discomfort associated with menopause are due to fluctuations in the body's hormone levels. Menopause can last from six months to fifteen years, and sometimes even longer. Approximately 60-80% of women will experience "vasomotor disturbances", which manifest themselves primarily as uncomfortable and embarrassing hot flushes and night sweats. These can begin during perimenopause when you are still having regular menstrual periods, and persist throughout menopause itself. Other associated wellness issues may include sweating, fatigue, sleep disturbances, irritability, among others. Most women find this bothersome and disruptive, but don't know how to deal with it.
