What causes menopause?
As your body changes from your reproductive years, your egg supply decreases and your body begins to ovulate less often. The natural levels of your female hormones, estrogen and progesterone, can fluctuate up and down to cause changes in your periods and other symptoms such as hot flashes and mood swings. In time, your hormone levels drop so much that your periods stop.
