For many women who enter menopause naturally, their menstrual cycle first becomes irregular. On average, it stops completely within about 4 years. Other symptoms that can happen during this time include: 1  Mood swings. 2  Lower sex drive. 3  Hot flashes. 4  Sweating. 5  Racing heart. 6  Headaches. 7  Vaginal dryness and soreness. 8  Painful sex. 9  Trouble sleeping.
The first sign that you are nearing menopause is a change in your menstrual periods. They may become less frequent. And they may be lighter or heavier than you're used to. Menopause symptoms range from mild (or none) to severe. They include: Hot flashes. Sleep disturbances (insomnia). Emotional changes, such as mood swings or irritability. A change in sexual interest or response. Problems with concentration and memory that are linked to sleep loss and fluctuating hormones (not a permanent sign of aging).
