Bone Health After 50: What Keeps Your Skeleton Strong
Bone is the tissue people think about least and worry about most, usually in that order and usually too late. It causes no trouble for decades, gives no warning, and then a neighbour breaks a wrist on a flat pavement and the subject arrives all at once. Last Monday we touched on bone as part of the wider menopausal picture and said we would come back to it. This is that article.
This one covers bone itself: what it is, what changes, and what genuinely influences it. Questions about medication, scans or your individual fracture risk belong with your GP, and are worth asking.
Why Bone Rarely Comes Up Until It Has To
In clinic, nobody books an appointment about their bones. They book about a hip, a back, a shoulder, or because walking has quietly got harder. Bone comes up sideways, and usually as a worry rather than a fact:
A mother or an aunt who broke a hip, and the question of whether the same thing is waiting
A fall in the garden that was laughed off at the time and thought about a good deal afterwards
A friend of the same age who has just been told their bone density is low
A general sense of having become more breakable, with nothing specific to point at
It is worth saying plainly: none of this requires a diagnosis to be relevant to you. The useful work happens well before anyone measures anything, which is the whole reason for writing about it now.
What Bone Actually Is
The picture most of us carry is of the skeleton as scaffolding: solid, finished, holding everything else up.
Bone is nothing of the sort. It is living tissue with its own blood supply and its own repair system, and it is taken apart and rebuilt continuously for as long as you are alive.
That process is called bone remodelling. Small patches of old bone are broken down, and new bone is laid down in their place. It happens quietly, everywhere in the skeleton, all the time, which is the single most useful thing to understand about bone, because it means the skeleton is still responding to what you ask of it.
What Changes After Fifty
Bone is laid down faster than it is removed through childhood and early adulthood, and bone mass reaches its highest point — peak bone mass — somewhere around the late twenties.
After that the balance gradually shifts. A little more bone is removed than replaced, and density slowly falls. This is normal and it happens to everyone, and it is not evidence of having done anything wrong.
The rate is what varies, and it is influenced by family history, hormonal change, activity, diet, smoking and alcohol, and certain long-term conditions and medications.
For women, the years around the menopause are the steepest part of that curve. Oestrogen holds breakdown and rebuilding in balance, and as levels fall, rebuilding no longer quite keeps pace . The point we made in Menopause and Your Joints, Muscles and Bones: What Changes and Why last week.
Men lose bone too, more gradually and usually later. This is not a women's issue with men looking on.
Why Bone Responds to Being Used
Bone adapts to what is asked of it. When a bone is loaded, the cells that build bone are prompted to lay down more material in the place the load was felt. When nothing is asked of it, bone is quietly thinned out, which is why prolonged bed rest and long periods of inactivity cost density so quickly.
The practical consequence is that the kind of activity matters, not only the amount.
Carrying Your Own Weight
Walking, stairs, dancing, standing work in the garden. Anything where your legs are supporting your body rather than something else doing it for you.
This is why swimming and cycling, both genuinely good for you and both worth keeping, do very little for bone. The water or the bicycle takes your weight, and the signal never arrives. If they are the whole of your activity, it is worth adding something upright alongside them.
A Degree of Impact
Brisk walking on firm ground, coming down a step, heel drops at the worktop. Small, repeated jolts through the leg are a clear signal to bone, and they are easy to build into a day.
Muscle Working Hard
Carrying shopping, lifting a watering can, standing up out of a low chair. Muscle pulls on bone at the point where it attaches, and a muscle working against real resistance pulls hard.
This is also where the two halves of the picture meet, because the same work that loads bone builds the muscle that protects it.
What Bone Needs From Your Diet
Loading tells the body to build. Diet supplies the materials, and three things matter most.
Calcium is what the structure is made from, and most people can meet their needs through food, dairy, tinned fish with the bones in, tofu, green leafy vegetables, fortified plant milks.
Vitamin D is what allows that calcium to be absorbed. In the UK, sunlight is not a reliable source through the autumn and winter, and national guidance is that most adults should consider a daily supplement across those months.
Protein is the one that gets overlooked. Bone is not pure mineral: it has a protein framework that the mineral sits on, and the muscle pulling on bone needs protein too. Research consistently shows that older adults eating too little protein lose both muscle and bone more quickly.
Bone Strength Is Only Half of a Fracture
Whether a bone breaks depends on how strong it is, and equally on whether you fall in the first place and how you land.
Strong legs and steady balance keep people upright. They also allow a stumble to be caught and recovered rather than followed all the way down. Both improve with practice, at any age, and both decline quickly when they are not used.
What most often gets in the way is not motivation. It is a hip that objects to a longer walk, a stiff back after an hour in the garden, or a knee that has quietly shortened how far someone goes. Nobody decides to load their skeleton less; it happens gradually, one small adjustment at a time, and the loss of loading follows the loss of confidence rather than causing it.
That is a solvable problem rather than a fact of ageing. Osteopathy is well placed to work out what is actually driving a particular joint's symptoms and to get movement back, which is the necessary first step before any of the loading advice above becomes realistic. Where the issue is strength or balance rather than pain, Clinical Exercise & Rehabilitation and Reformer Pilates both build those in a controlled and progressive way, and you can see the full range on our services page.
What This Means in Practice
Three things are worth taking away.
Nothing about declining bone density is felt. There is no pain, no stiffness and no early symptom, which is why it stays off the list until something breaks and puts it there. If you have risk factors or a family history of osteoporosis, that is a reason to raise it with your GP now rather than later.
Bone remodelling continues for life, so the tissue is still listening at fifty, at seventy and beyond. That is an argument for starting now rather than filing it under things to think about later.
And loading is the intervention, alongside eating enough of the right things. Thursday's article sets out exactly how to do that at home, with a chair, a wall and the bottom stair. For how strength and balance work together in this, Why You Need Both Strength and Mobility is a useful companion piece.
Apollo Insight
Bone is unusual in that most people are still in good time to do something about it, and nothing tells them so.
Nothing about losing density is felt, so there is no moment that prompts action. A sore knee books its own appointment; bone never does. Which means the people best placed to benefit from all of the above are precisely the people with no particular reason to go looking for it.
In clinic the conversation almost always starts from something else — a hip that has shortened the usual walk, a back that objects to an afternoon in the garden. That is a perfectly good place to start, because the thing that most often costs people bone is not a diagnosis. It is a slow, unremarked reduction in what they do, one small adjustment at a time, usually because something aches and nobody looked at it.
