The essentials
This symptom is caused by the hormonal shifts your body is going through. Understanding what's happening helps you better cope with what you're feeling.
The cause
Oestrogen keeps bone breakdown and bone building in balance. When your oestrogen falls in menopause, bone is broken down faster than it is replaced. That loss is fastest in the first years after your final period. You feel nothing while it happens, which is exactly why osteoporosis is so often noticed late.
What helps
Strength training and weight-bearing exercise, enough calcium from food, adequate vitamin D, not smoking and going easy on alcohol. If you are at higher risk, a bone density scan (DEXA) gives you clarity. A care provider who knows menopause can help you decide whether follow-up or treatment is needed.
Honest and transparent
The most frequently asked questions
Two terms for stages of the same process, and the difference matters. Osteopenia means your bone density is lower than normal but has not yet reached the threshold for osteoporosis. Osteoporosis is the advanced stage, where bone has become so porous that it breaks easily. Both are measured with the same scan, so one score tells you where you stand.
Usually you don't, and that is what makes it tricky. Osteoporosis causes no pain and no symptoms for years. It often comes to light only when a bone breaks after a minor fall, or when you gradually lose height and your posture becomes more stooped. That is why it helps to know whether you are at higher risk before anything breaks.
It comes down to oestrogen. Your bone renews itself throughout life: old bone is broken down and new bone takes its place. Oestrogen keeps that process balanced. When oestrogen falls in menopause, the balance tips towards breakdown, and this is fastest in the first years after your final period.
Not every woman needs one, which is reassuring. A DEXA scan is most useful if you carry extra risk: an early menopause, a parent who broke a hip or spine, long-term steroid use, a low body weight, or a previous fracture from a minor knock. In Belgium the scan is reimbursed under set conditions: women over 65 with osteoporosis in the family, and at any age with risk factors such as an early menopause, long-term steroid use, a previous fracture or rheumatoid arthritis. Reimbursement applies at most once every five years. Your GP can judge with you whether it is worth doing now.
They are the foundation, but they don't do the work alone. Calcium is the building block of bone and vitamin D helps you absorb it. Fall short on either and your bones lack raw material. Even so, calcium protects your bones best combined with exercise, and sometimes with further treatment. Food first, a supplement where needed, in consultation with a doctor.
Yes, and it is an honest answer women aren't always given. Hormone therapy slows the bone loss that starts at menopause and lowers the risk of fractures. Guidelines regard it as a valid option to prevent osteoporosis, particularly in women under 60 or within ten years of menopause. Whether it suits you depends on your full picture, and that is a conversation to have with a care provider.
Osteoporosis is the symptom you cannot feel. No pain, no fatigue, no sign that anything is changing. Your bones grow quietly weaker, year on year, and most women only find out when something breaks. Menopause is when that loss accelerates most. Below you will read why it happens, who is at higher risk, how it is detected and what actually keeps your bones strong.
A symptom you cannot feel
Most menopause symptoms announce themselves: hot flushes, broken sleep, a foggy head. Osteoporosis does not. It develops silently and shows itself late. Often the first clue is a fracture after a fall that would once have caused nothing at all, a wrist or a hip that gives way after a stumble.
Unlike joint complaints or muscle pain, which also become more common in menopause, osteoporosis brings no nagging ache to warn you. That is exactly why it pays to think ahead. Worldwide, around one in three women over fifty will have a fracture caused by osteoporosis.1 That is not a reason to worry, but a reason to know where you stand.
Why your bones lose density now
Bone looks solid and unchanging, but it renews itself throughout your life. Old bone cells are constantly broken down and replaced by new ones. As long as the two stay balanced, your bone stays strong.
Oestrogen plays a key role here: it slows the breakdown. When your oestrogen level starts to fall in menopause, that brake comes off. Breakdown outpaces building, and your bone density drops.
The loss is greatest in the first years after your final period. In that window, women can lose up to a fifth of their bone mass.1 After that it slows again. Those early years are the window where there is most to protect.
Who is at higher risk?
Osteoporosis does not affect every woman equally. Some factors raise the risk, and most are ones you can go through with your GP.
An early menopause, before forty, means your bones spend longer without the protection of oestrogen. A hip or spine fracture in a parent points to an inherited susceptibility. Long-term steroid use (corticosteroids) speeds up bone loss, as do smoking and heavy drinking. A low body weight or a slight build matters too: less bone to start with.
Recognise yourself in one or more of these? That is not a diagnosis, but it is a good reason to start the conversation before anything goes wrong.
Losing height and a stooped back
There is one signal you can notice: your height. As vertebrae gradually compress, you become a few centimetres shorter and your back curves forward. This often happens without sharp pain, gradually over the years.
Do take note of sudden, severe back pain with no clear cause, or back pain that worsens when you stand or walk. That can point to a vertebral fracture and deserves a check with your doctor. If you fall and break something from a limited impact, have your bone density checked too, whatever your age.
How osteoporosis is detected
Because you feel nothing, a measurement is the only way to be sure. That is done with a bone density scan, the DEXA scan (bone densitometry). It is a short, painless scan with a very low radiation dose that measures the density of your bones, usually at the hip and lower spine.
You receive the result as a T-score. According to the World Health Organization, osteoporosis is defined by a T-score of -2.5 or lower. Between normal and that threshold sits osteopenia: reduced bone density that warrants attention but is not yet osteoporosis.
In Belgium, reimbursement comes with set conditions. It applies to women over 65 with osteoporosis in the family, and at any age or sex where specific risk factors are present: an early menopause, long-term steroid use, a previous fracture or rheumatoid arthritis. The scan is then reimbursed at most once every five years. Your GP weighs up whether you meet the criteria and whether it is worth doing now. In doubt? Ask. Clarity beats waiting until something breaks.
What you can do yourself
You don't prevent osteoporosis with a single measure, but with habits that support your bone from several sides. They work best when you start early, in the years around menopause.
- Train your muscles and load your bones. Bone grows stronger from force and from impact. Strength training, brisk walking, climbing stairs or jumping prompt your bones to reinforce themselves.
- Get enough calcium from food. Dairy, green vegetables, nuts and calcium-rich water supply the building blocks. Food comes first, a supplement only where it is needed.
- Mind your vitamin D. Vitamin D helps you absorb calcium. In our latitudes your skin makes too little of it in winter, so a supplement is often sensible.
- Stop smoking and go easy on alcohol. Both speed up bone loss. Cutting back pays off at any age.
You don't have to do this perfectly. Consistency matters more than intensity.
Does hormone therapy protect your bones?
Here the answer can be clear: yes. Hormone therapy slows the accelerated bone loss of menopause and lowers the risk of fractures. Both Belgian and international guidelines recognise this.2,3,4,5,6
For women under 60, or within ten years of their final period, hormone therapy counts as a valid option to prevent osteoporosis, especially when you also have other menopause symptoms. Whether it suits you depends on your personal situation and history.
There are also medicines that act specifically on bone, such as bisphosphonates. They count as a full alternative to hormone therapy. Which treatment fits best depends on your bone density, your fracture risk and your history. That is something you decide together with a doctor.
Where to find help
If you want to know whether your bones need attention, you don't have to work that out alone.
Your GP (huisarts) is a good first stop. They go through your risk factors, request a bone density scan if needed, and refer you to a gynaecologist or a doctor who specialises in bone health. Some Belgian hospitals also run a dedicated osteoporosis or menopause clinic.
