Menopause is when a woman undergoes 12 consecutive months without having regular menstrual periods. It is part of the aging process and indicates that women can no longer have babies. Some women experience early menopause and experience symptoms between 40 to 45 years or before 40. The early menopause symptoms include weight gain, difficulty sleeping, vaginal dryness, a missing period for more than three times in a row, and lighter or heavier menstrual flow than usual regular periods, and many more.
