What it means

Premature menopause is when periods stop before about age 45, due to primary ovarian insufficiency, ovary removal, or cancer treatment, causing an early drop in estrogen.

Why it matters for your bones

Losing estrogen decades early means more years of accelerated bone loss, so this is a key moment to ask about bone protection with your doctor.

Premature menopause happens when periods stop before roughly age 45. This can happen on its own, through a condition called primary ovarian insufficiency, or because of surgical removal of the ovaries or cancer treatment. Either way, it means your body loses estrogen much earlier than usual, which is why the situation is treated differently from typical menopause in a woman's early fifties.

The concern is that this early drop in estrogen means decades of extra time exposed to accelerated bone loss, compared to someone whose ovaries kept working into their early fifties. Because of this, major guidelines generally support hormone replacement at least until you reach the average age of natural menopause, unless there's a specific reason that isn't appropriate for you. Bone health is one of the key reasons for this, alongside heart and cognitive health.

Decisions about hormone replacement always belong to you and your prescriber, based on your full health picture. But if you've gone through premature menopause and no one has ever talked with you about protecting your bones, that's worth bringing up at your next appointment. It's described as one of the clearest situations in this field, yet it's often missed.
