Menopause is one of the main causes of low estrogen levels. It begins and ends at a slightly different age for each woman, but it generally occurs between the ages of 45 and 60, with the average age being 51. Estrogen is one of the main female hormones produced by the ovaries; it helps the uterus get ready to receive a fertilized egg. One of the signs that menopause is around the corner is the decreasing levels of estrogen. The average woman’s body will begin to lose estrogen and show symptoms as early as 10 years before the start of menopause. This is typically when it is time to start looking at effective night sweats treatment options.
