If you have noticed more conversations about bone density lately, you are not imagining it. The years around menopause are when many women lose bone faster than at any other time in adult life. The good news is that bone loss is not a mystery, and a lot of what protects your bones is within your control. As an independent publication that sells no hormones and is not a medical provider, our goal here is simply to help you understand the science so you can have a smarter conversation with your own clinician.

Why bone loss speeds up at menopause

Here is the core of why it happens. Estrogen helps keep bone remodeling in balance. Throughout life, your body is constantly breaking down old bone and building new bone. Estrogen acts as a brake on the cells that break bone down (osteoclasts) while supporting the cells that build it (osteoblasts). When estrogen drops at menopause, that brake loosens. Bone gets broken down faster than it is rebuilt, and density falls.

The pace can be surprising. According to the Endocrine Society, women can lose up to about 10 percent of their bone mass in the first five years after menopause. That accelerated stretch is why this stage of life matters so much for long-term bone health, and why menopause is the most common reason women develop osteoporosis.

Osteoporosis means bones have become porous and fragile enough to break easily, sometimes from a minor fall or even routine movement. It usually has no symptoms until a fracture happens, which is why it is often called a silent condition. Hip and spine fractures in particular can seriously affect independence and health later in life, which is what makes prevention worth taking seriously now, not later.

How to protect your bones in menopause

So what actually helps? The evidence points consistently to a few things.

Move in ways that load your bones. Bone responds to stress by getting stronger, so weight-bearing and muscle-strengthening exercise both matter. Mayo Clinic and the Bone Health and Osteoporosis Foundation point to a combination of:

  • Weight-bearing activity such as walking, hiking, dancing, or stair climbing
  • Strength or resistance training a couple of times a week
  • Balance work like yoga or tai chi, which helps prevent the falls that cause fractures

Get enough calcium and vitamin D, ideally from food first. For women over 50, the recommended dietary allowance is about 1,200 mg of calcium per day, and 600 to 800 IU of vitamin D, per the National Institutes of Health. Food sources count: dairy, fortified plant milks, canned fish with bones, leafy greens, and tofu. One nuance worth knowing: the U.S. Preventive Services Task Force found insufficient evidence to recommend routine supplements for fracture prevention in healthy, community-dwelling postmenopausal women, and more is not better. Whether you need a supplement depends on your diet and blood levels, which is a good thing to review with a clinician rather than guess at.

Mind the other levers. Smoking and heavier drinking both work against bone, and being significantly underweight is a risk factor too. If you want a low-pressure starting point, Menova offers a free self-check that can help you organize what to bring up at your next appointment.

When to get a DEXA bone density scan

When does screening like a DEXA scan matter? A DEXA (also written DXA) is a quick, low-radiation scan that measures bone mineral density. The U.S. Preventive Services Task Force and ACOG recommend bone density screening for all women starting at age 65. Screening earlier, in postmenopausal women under 65, is recommended when a formal risk assessment (such as the FRAX tool) suggests elevated fracture risk, for example because of a family history of hip fracture, prior fragility fracture, certain medications like long-term steroids, or low body weight. Your clinician can run that risk assessment and decide whether and when a scan makes sense for you.

Hormone therapy and bone protection

Hormone therapy has a real, but specific, role. Menopausal hormone therapy is FDA-approved for the prevention of postmenopausal osteoporosis, and research shows it reduces bone loss and fracture risk, especially when started within about 10 years of menopause or before age 60. In November 2025, the FDA announced it was revising the labeling on these products, including removing long-standing boxed warnings, citing newer analyses of benefits and risks. That said, hormone therapy is not right for everyone, and it is generally one option among several (including non-hormonal bone medications for higher-risk women). The decision depends on your symptoms, your fracture risk, and your personal and family medical history. The Menopause Society emphasizes that this is an individualized choice to make with a knowledgeable clinician, not a one-size-fits-all answer.

Signs a fracture may already have happened

Bone density is a prediction. A fracture is the event the prediction is about — and the commonest osteoporotic fracture, in the spine, usually causes no obvious moment at all. Most are never diagnosed.

Measure your height. Shoes off, heels and back against a wall, someone else marking the top of your head. Compare it with your peak adult height, usually what you were in your twenties. A loss of a few centimetres is a finding rather than an inevitability, and it is the main clue that a vertebral fracture has occurred. Thresholds differ between services — ask what yours uses.

Other signs worth raising:

  • A new rounding of the upper back, or clothes fitting differently through the body while your weight has not changed
  • Back pain that started suddenly, particularly after something trivial like lifting a bag or a heavy sneeze
  • Any fracture from a fall from standing height after 50 — that is the definition of a fragility fracture and it changes the assessment
  • Sudden severe back pain, which should be assessed promptly
  • Back pain with numbness, weakness, or loss of bladder or bowel control — this is an emergency

Why it matters: one vertebral fracture substantially raises the risk of the next one and of a hip fracture, and it is the strongest single signal that treatment should be discussed. The fuller version is height loss and the fractures nobody notices, and what to do with a scan result is in what to do about a DEXA result.

The bottom line: bone loss around menopause is real and can be fast, but it is also one of the most actionable parts of this transition. Steady movement, good nutrition, knowing your risk, and timely screening go a long way.

Density is only half of it — fracture requires a fall, and balance responds far faster than bone does. See the half of bone health nobody talks about.
