Bone density falls fastest in the years around menopause, because falling estrogen lets bone break down faster than the body rebuilds it. Cleveland Clinic states that women can lose up to 20% of their bone density within five years of starting menopause. The loss is silent, so a DEXA scan is the only way to see where you stand. Repeating the scan and comparing results is how you see where you are heading. This guide covers what happens, who should be scanned, how to read the numbers, and which steps have evidence behind them.
TL;DR
- Estrogen protects bone. When it drops at menopause, bone loss speeds up, by as much as 20% in the first five years or so, according to Cleveland Clinic.
- Screening with a DEXA scan is recommended for women 65 and older, and for postmenopausal women under 65 with risk factors, per the USPSTF.
- A T-score of -1.0 or higher is normal, -1.1 to -2.4 is osteopenia, and -2.5 or lower is osteoporosis.
- Calcium, vitamin D, protein and weight-bearing exercise support bone, but medication may be needed if you are at high fracture risk. Talk with your doctor.
- One scan is a snapshot. Comparing the same site across scans shows your direction.

What happens to bone after menopause
Bone is living tissue. Old bone is constantly broken down and replaced with new bone. Through most of adult life the two processes stay roughly in balance. Estrogen is a big part of that balance. Dr. Pelin Batur of Cleveland Clinic describes estrogen as having a very protective role until menopause, helping with bone development and with keeping bone density up. When estrogen falls, women go through a rapid drop in density.
The Endocrine Society calls menopause the most common cause of osteoporosis. It explains that estrogen slows the natural breakdown of bone, so losing it speeds up bone loss significantly. Dr. Louise Collins of Stony Brook Medicine adds that catching bone loss early gives women more options to slow it down.
How much bone you can lose
The figure you will see most often is up to 20%. The Endocrine Society says that much bone loss can occur across the menopause transition and the postmenopausal years. Cleveland Clinic places it within about five years of the start of menopause. These are upper estimates, not a promise for every woman. Your own loss depends on your starting bone mass, genetics, body weight, medications, activity and other factors.
That spread is exactly why measuring matters. Two women of the same age can have very different trajectories, and an average tells you little about yours.
Bone loss, osteopenia, osteoporosis and fractures
Lower bone density is not a disease on its own, but it is the road toward one. NIH News in Health explains that osteopenia means bone density lower than normal but less severe than osteoporosis. It can be an early warning sign, and it can still raise fracture risk.
The stakes are real. The Endocrine Society states that one in two postmenopausal women will have osteoporosis, and that most will suffer a fracture in their lifetime. Stony Brook Medicine, citing the Bone Health & Osteoporosis Foundation, notes that about one in two women over 50 will break a bone because of osteoporosis.
The Endocrine Society also advises that any fracture after menopause should be considered an osteoporotic fracture and treated aggressively. If you have broken a bone after menopause, mention it to your doctor and ask whether bone density testing and treatment are appropriate.
For a wider look at low bone density and fracture risk, this guide on low bone density and fracture risk is a good companion read.
When to get a DEXA scan after menopause
DEXA (also written DXA) is the standard bone density test. It uses very low-dose X-rays to measure bone mineral density, most often at the hip and lumbar spine. The USPSTF recommends osteoporosis screening for:
- Women 65 years or older (Grade B).
- Postmenopausal women younger than 65 who have one or more risk factors, as estimated by clinical risk assessment (Grade B).
It names central DXA at the total hip, femoral neck or lumbar spine as the most commonly used screening test.
Risk factors that can justify scanning earlier
NIH News in Health says a doctor may suggest earlier testing if you have had falls, have conditions such as thyroid problems or rheumatoid arthritis, or take drugs such as corticosteroids. Cleveland Clinic adds a previous fracture, low body weight (under 127 pounds), a history of smoking, a family history of osteoporosis, diabetes, and long-term steroid use.
If any of these apply and you are under 65, ask your doctor about a baseline scan. Having one early gives every later scan something to be compared against.
How often to repeat it
There is no single schedule. iMedic reports that people with normal bone density may wait 10 to 15 years before rescanning. Those with osteopenia typically repeat every 1 to 5 years depending on risk, and people on osteoporosis treatment often have follow-up scans every 1 to 2 years to check response. Your doctor sets the interval for your situation.
How to read your DEXA results
Your report is usually a few pages of tables, charts and abbreviations. The number most people look for is the T-score, which compares your bone density with that of a healthy young adult. Medical News Today gives the ranges:
| T-score | What it means |
|---|---|
| -1.0 or higher | Normal bone density |
| -1.1 to -2.4 | Osteopenia (low bone density) |
| -2.5 or lower | Osteoporosis |
Two details from iMedic help you read the report. For diagnosis, the lowest T-score at any measured site is typically used. And each 1.0 drop in T-score approximately doubles fracture risk, so small-looking differences carry meaning.
The T-score is a diagnosis tool. For watching change over time, doctors compare the same site on successive scans. Comparing your spine on one scan with your hip on the next tells you nothing. That is the reason to keep every report and line them up site by site.
Why tracking across scans matters
Medical News Today notes that a doctor may schedule another DEXA scan in a few years to look for changes and to monitor how well treatment works. Reports from different clinics use different layouts, and PDFs end up buried in email or patient portals. After two or three scans, most people cannot easily see their own trend.
What we have learned from reading scan reports
We built DEXA.report because the most useful thing about a DEXA scan is not one number but the line between several of them. A single T-score tells you where you are. Two or three scans tell you whether you are holding steady, slipping or responding to a change you made.
In our experience the barrier is rarely the science. It is that reports arrive as dense PDFs, in different formats from different clinics, and nobody has the time to retype figures into a spreadsheet. So you upload the PDF from any clinic and we turn it into a dashboard with trends, body region breakdowns and side-by-side scan comparisons, with plain-language summaries that explain what you are looking at.
We also think health data should stay yours. Your data is stored in the EU and accessible only to you. That is a design decision, not an add-on. We want you to walk into your next appointment knowing your own numbers and ready to ask better questions.

What supports bone density after menopause
No single habit replaces the rest. The evidence points to a combination: nutrition, the right kind of movement, avoiding things that harm bone, and medical treatment when risk is high.
Calcium and vitamin D
Needs go up after menopause. Mayo Clinic lists the recommended dietary allowance for calcium as 1,000 mg a day for adults 19 to 50 and 1,200 mg for women 51 and older. For vitamin D it is 600 IU a day up to age 70 and 800 IU after that. Johns Hopkins Medicine gives the same step-up after menopause.
Food sources named by Mayo Clinic include dairy, turnip greens, salmon, sardines, tuna and soy products for calcium, and oily fish and fortified foods for vitamin D. The Endocrine Society explains why vitamin D matters: without enough of it, your body will not absorb the calcium you eat.
What about supplements?
This is where guidance has shifted. University Hospitals notes that the USPSTF no longer recommends calcium and vitamin D supplements for fracture prevention in older adults, while the nutrients themselves remain vital. The VITAL trial, covered by the San Francisco Chronicle, found that 2,000 IU of vitamin D daily did not significantly reduce fractures in healthy middle-aged and older adults. The same article gives upper safety limits of about 2,200 mg of calcium and 4,000 IU of vitamin D a day. Ask your doctor whether your diet is covering your needs before you add supplements.
Weight-bearing and resistance exercise
NIH News in Health recommends enough calcium, vitamin D and protein plus weight-bearing exercise such as strength training, walking, hiking, jogging, tennis or dancing. It quotes Dr. Rao, who calls regular weight-bearing and resistance exercise probably the secret to maintaining bone health. If you already have osteoporosis or fractures, ask your doctor or a physical therapist which exercises are safe for you before starting.
Habits that cost bone
Smoking and heavy alcohol use are widely listed as bone risks, and smoking history is one of the factors Cleveland Clinic gives for earlier testing. Falls matter just as much as density. The North American Menopause Society says fall prevention is especially important for older women and those with reduced mobility.
Hormone therapy and other medication
A 2025 systematic review in PMC found that hormone replacement therapy produced greater bone density gains than exercise alone in postmenopausal women. Adding exercise to HRT gave the largest improvement: 0.8% more at the femoral neck and 2.7% more at the lumbar spine than exercise alone. It also found that density declined after HRT was stopped. Hormone therapy has its own risks and benefits, so the decision belongs with your doctor.
Cleveland Clinic reports that about 5% to 15% of women still lose bone on hormone therapy, and that bisphosphonates are much more effective than hormones at preventing fractures. If your scan shows osteoporosis or high fracture risk, ask your doctor which medication fits you.
Can you reverse bone loss?
Honest answer: it depends on what you mean by reverse. The North American Menopause Society’s 2021 position statement says that for women at high risk, especially perimenopausal women with low bone density and other risk factors, estrogen or other therapies are available to prevent bone loss. It describes the main goal of treating osteoporosis as preventing new fractures, using a mix of lifestyle measures, drugs that increase bone density, and fall-reduction strategies.
The practical reading: lifestyle measures are a foundation, and they work best alongside the treatment plan your doctor builds if your risk is high. Many women aim first to hold their numbers steady, and a series of scans is how you confirm that is happening.
Turning your scans into a trend
Here is a simple routine that makes scans useful.
- Get a baseline. If you are postmenopausal and have risk factors, ask your doctor about a first scan.
- Keep every PDF. Ask for the full report, not just the summary letter.
- Use the same site and, where you can, the same clinic or machine type. Comparisons are most meaningful at the same site, such as the lumbar spine or femoral neck.
- Record what changed between scans. Medication starts, new exercise, weight changes and falls all belong in the story.
- Bring the trend to appointments. A chart of your own results makes the conversation with your doctor more specific.

FAQ
How much bone density do you lose after menopause?
Estimates say up to 20% over the menopause transition and the following years, with Cleveland Clinic placing it within about five years of menopause starting. It varies a lot from woman to woman. A DEXA scan shows your own number.
Is a DEXA scan recommended after menopause?
The USPSTF recommends screening for women 65 and older, and for postmenopausal women under 65 who have risk factors for osteoporosis. Risk factors include a previous fracture, low body weight, smoking history, family history and certain medications. Your doctor can tell you whether you should be scanned earlier.
How can I improve bone density after menopause?
Get enough calcium, vitamin D and protein, and do weight-bearing and resistance exercise regularly. If your risk of fracture is high, medication such as hormone therapy or bisphosphonates may also be recommended. Discuss which approach fits your health history with your doctor.
How often should I repeat a bone density scan?
It depends on your results. Normal bone density may mean waiting many years, osteopenia often means rescanning every 1 to 5 years, and people on treatment commonly rescan every 1 to 2 years. Your doctor will set the schedule.
