Early menopause, also known as premature menopause, is when menopause happens before the age of 40. One reason for early menopause is premature ovarian failure.
Different reasons for early menopause include injury to the ovaries by chemotherapy as well as radiation treatments, or surgery of the ovaries.
Complications that are brought about by early menopause include infertility and an expanded risk for osteoporosis.
Other rare causes that may prompt early menopause include medications, chronic illnesses, pituitary and hypothalamic tumors, psychiatric problems, and other moderately uncommon or indistinct conditions.
