The point that bone density falls quickly when female hormones decrease in menopause has been covered in a previous article. Yet in the clinic, many people focus on a single bone-density test number and miss the more important question—namely, "what is my likelihood of breaking a bone within the next 10 years." The ultimate goal of osteoporosis management is not to make the test numbers good but to prevent fractures. In this article, let us look at how to assess fracture risk, which is not visible from bone-density measurement alone, and how to prepare fall prevention and treatment.
Why fracture risk matters more than the bone-density number
What really needs to be weighed in osteoporosis management is not the bone-density value itself but the likelihood of a bone breaking in the future. Even with the same T-score on a bone-density test, the actual fracture risk can be much higher for someone who is older, has had a prior fracture, or whose parent suffered a hip fracture.
The Korean Society of Menopause and the North American Menopause Society (NAMS) 2021 position statement clearly place the primary goal of post-menopausal osteoporosis management on the prevention of new fractures. In other words, the criterion when deciding whether to use medication and how far to change lifestyle is not "bone density is low" but the comprehensive judgment of "how high is this person's fracture risk."
So in care, along with bone density, we look at the following factors together.
- Age, timing of menopause, and whether menopause was early
- Past fracture history, especially fractures from minor impact
- A family history of parental hip fracture
- Smoking, heavy drinking, and a thin build (low body mass index)
- Secondary causes such as rheumatoid arthritis and long-term steroid use
If you check these risk factors from the time menopausal symptoms begin, you can prepare before bone density drops greatly. If you are curious about changes around menopause, please also refer together to the article organizing when menopausal symptoms typically begin.
FRAX, a tool to see 10-year fracture risk as a number
To view an individual's fracture risk a bit more objectively, in clinical practice we use an assessment tool called FRAX. FRAX is a calculation tool developed by a World Health Organization (WHO) collaborating center in 2008, which shows the probability of a major osteoporotic fracture and a hip fracture occurring within the next 10 years as a percentage.
FRAX calculates by adding the clinical risk factors mentioned earlier on top of age and sex. The interesting point is that risk can be estimated even without entering a bone-density value, and accuracy rises further if the femoral bone-density value is entered together. So it is especially useful for those in the osteopenia range, where bone density is ambiguously low.
Even if you were told on a bone-density test that "it is not osteoporosis yet," if the fracture risk calculated by FRAX comes out high, active management or treatment may be needed. Looking at the overall risk is the key, more than the diagnostic name on one line of a test.
International guidelines recommend drug treatment when the 10-year major fracture risk calculated by FRAX exceeds a certain threshold. By the criteria of the US National Osteoporosis Foundation (NOF), it advises considering the start of treatment when the major osteoporotic fracture risk is high or the hip fracture risk exceeds a threshold. However, since these criteria are set based on population groups and cost-effectiveness, the actual application is decided by consulting with the medical team according to individual condition.
DXA bone-density test, who should receive it and when
The starting point of fracture risk assessment is accurate bone-density measurement. The most standard method is dual-energy X-ray absorptiometry, that is, measuring the bone density of the lumbar spine and hip bone with DXA. It has a low radiation dose and good reproducibility, so it is also suitable for follow-up observation.
A question often received in the clinic is "when should I get tested?" Generally, a DXA test is recommended in cases such as the following.
| Target | Reason testing is recommended |
|---|---|
| Women aged 65 and over | Age itself is a major fracture risk factor |
| Amenorrhea lasting 6 months or more | A signal of estrogen deficiency regardless of age |
| Imaging findings suspicious for vertebral fracture or osteoporosis | Bone weakening may already have progressed |
| Having started or receiving osteoporosis treatment | Tracking treatment response is needed |
| Having risk factors such as early menopause or long-term steroid use | Early assessment needed even before age 65 |
The test result is expressed as a T-score, and even the same value gains meaning only when interpreted together with the risk factors explained above. If you want to know more about how the bone-density test is used in diagnosis, referring to the article explaining how to diagnose osteoporosis is helpful.
The bone mass built up when young governs your whole life
The most fundamental strategy in osteoporosis prevention is to raise bone density as much as possible when young. Our body's bone mass usually reaches its peak in the late 20s to early 30s and then gradually decreases, and the higher this peak bone mass, the later one enters the risk range even as bone density falls after menopause.
So in the growth period and young adulthood, a balanced diet rich in calcium and vitamin D, and exercise that places sufficient load on the bones, are important. The International Osteoporosis Foundation (IOF) recommends about 1,200 mg of calcium a day for post-menopausal women, along with supplementation to keep blood vitamin D at an appropriate level. For those aged 60 and over, vitamin D supplementation at the level of 800 to 1,000 IU a day is reported to help with muscle strength and bone health.
If dietary management feels daunting, looking together at the article organizing what to eat more after menopause and the article dealing with the meaning of menopause and vitamin D will help you find things to practice at the table. If your usual meals are irregular or you are worried about absorption, you can also be consulted about IV nutrient therapy or tailored supplementation through testing.
Preventing falls is preventing fractures
A considerable number of osteoporotic fractures in old age start from falls. No matter how weak the bones are, if you do not fall it does not lead to a fracture, so fall prevention is a fracture-prevention strategy no less important than medication. In clinical experience, many people are diligent about taking their medication but leave the home environment as it is, whereas the two going together produces a greater effect.
If we organize items worth checking in daily life, they are as follows.
- Applying anti-slip treatment to slippery places such as the bathroom and flooring
- Tidying up tripping hazards such as floor cords, carpet edges, and thresholds
- Wearing comfortable shoes with a low heel and non-slip soles
- Placing sufficient lighting in dark hallways and stairs
- Correcting problems with vision and hearing if present
In addition to this, exercise that builds balance and lower-body strength is a great help. The recommendations of the International Osteoporosis Foundation (IOF) and the menopause society advise doing weight-bearing exercise and strength-strengthening exercise together, and it is also reported that vitamin D supplementation contributes to reducing body sway and fall risk. If you are curious about the link between muscle and bone health, please also read the article dealing with menopause hormone management and muscle/bone health.
Consult about my fracture risk and the timing of testingDrug treatment and hormone management, when are they considered
When it is difficult to lower risk sufficiently with lifestyle management alone, drug treatment is considered. In cases where bone density falls quickly after menopause, the fracture risk seen by FRAX is high, or osteoporosis has already been diagnosed, treatment can be started in consultation with the medical team.
The NAMS 2021 position statement proposes, for those at very high fracture risk, an order of first using a bone-building drug and then continuing with a drug that prevents bone loss. Which drug to use and how much differ depending on the risk level, comorbidities, and the individual's situation, so it is hard to state uniformly. Since there can be individual differences in treatment effect and side effects, regular follow-up observation is needed.
In the comparatively early period around menopause, hormone therapy is sometimes reviewed by considering menopausal symptom control and bone protection together. However, since hormone therapy requires carefully weighing the starting point and indications, we recommend referring to the article dealing with when to start menopausal hormone therapy and how long to continue it and then confirming your condition through menopause screening. The specific management and treatment process after diagnosis will be covered in more detail in the next article.
In summary: we look at the whole risk, not one line of numbers
Menopausal bone health is not determined by a single bone-density number. The key is to assess the whole fracture risk gathered from age, family history, past fractures, and lifestyle, and to prepare stepwise accordingly—diet and exercise, fall prevention, and medication if needed. If amenorrhea is prolonged, or you have early menopause or a family history of fracture, we recommend checking bone density and risk level once without being bound by age.
If you are unsure whether it is the point to be tested, or which management to start with now, let us organize it together through a medical visit.
