Menopause is a normal change in a woman’s life and marks the end of the fertile years. It occurs when the ovary ceases to produce the hormones estrogen and progesterone. Menopause is diagnosed after a woman has had no menses for 12 months consecutively. This often happens between late 40s to early 50s. Though menopause happens naturally with age, it can also stem from other factors; such as, surgery, treatment of a disease, or an illness. In these cases it can be called induced menopause, surgical menopause, or primary ovarian insufficiency, depending on the cause.
