Why do you get osteoporosis after menopause?

It’s mainly because of dropping estrogen levels

• Estrogen is a key hormone that helps protect your bones.
• It does this by slowing down the process that breaks down old bone (bone resorption) and helping build new bone. What happens after menopause?
• When you reach menopause, your ovaries make much less estrogen.
• This sudden drop removes that protective effect on your bones.
• As a result, bone breakdown (loss) speeds up, and new bone doesn’t form fast enough to keep up. The numbers show it clearly:
• Women can lose up to 20% of their bone mass in the first 5–7 years after menopause.
• That’s why the risk of osteoporosis (thin, fragile bones that can break easily) goes up sharply after menopause. Why does this matter?
• Weaker bones are more likely to fracture, especially in the spine, hip, and wrist.
• Hip fractures in older women can be very serious, even life-threatening, because they often lead to long recoveries and loss of independence.

Quick summary After menopause, lower estrogen means faster bone loss. This can lead to osteoporosis, making bones thin and fragile. That’s why calcium, vitamin D, and weight-bearing exercise become extra important after menopause.
