Postmenopause: This is the name given to the period of time after a woman has not bled for an entire year (the rest of your life after going through menopause). During this stage, menopausal symptoms, such as hot flashes, may ease for many women. Menopause is signalled by 12 months since last menstruation. Common symptoms include hot flashes and vaginal dryness. There may also be sleep disturbances. The combination of these symptoms can cause anxiety or depression. Menopause is a natural process with treatments that focus on symptomatic relief. Vaginal dryness is treated with topical lubricants or oestrogen. Medications can reduce the severity and frequency of hot flushes. In special circumstances, oral hormone therapy may be used. Some women can experience menopause early, either as a result of a surgical intervention (such as removal of the ovaries) or damage to the ovaries (such as from chemotherapy). Menopause that occurs before the age of 45, regardless of the cause, is called early menopause. Menopause that occurs at 40 or younger is considered premature menopause.
