Insomnia is a common symptom of menopause. However, insomnia often shows up years in advance of menopause, while still in the perimenopause phase so the association is not always evident. The fact is, the most common cause of insomnia is hormonal imbalance, so it is no wonder menopause and insomnia go hand in hand.
It has traditionally been thought that menopause and insomnia were linked because of hot flashes and night sweats which can interfere with the ability to sleep. However, it is now thought the connection lies in decreased levels of serotonin in the brain due to dropping estrogen levels in the blood.
A natural and gradual change.
Menopause is the final menstrual period that usually occurs between the ages of 48 to 52. It is not unusual for this to occur earlier or as late as the mid- fifties. Menopause is part of a longer life transition of hormonal change that may start in the early, mid, or late forties and occasionally earlier.
Many use the word menopause to describe the time women experience hormonal fluctuation associated with menstrual changes and hot flashes. This time of adjustment is actually called the Climateric or more commonly perimenopause or mid- life transition. Post menopause occurs 12 months after the last menstrual period.
