What is Early and Premature Menopause?

Early menopause happens when periods stop between the ages of 40 and 45, while premature menopause (also called premature ovarian insufficiency) refers to menopause occurring before age 40. It can happen naturally, or as a result of surgery, certain medical treatments like chemotherapy, or underlying medical conditions.

Because it happens earlier than typical, early or premature menopause carries a slightly higher long-term risk of conditions like osteoporosis and heart disease, which is why hormone replacement therapy (HRT) is often specifically recommended until at least the average age of natural menopause, alongside managing any symptoms.
