What changes quietly: bones, heart and the numbers worth knowing now

At least symptoms give you feedback. This second thing does not hurt, announces nothing and first speaks up fifteen years later.

You get used to symptoms at least in the sense that you know they are there. You do not sleep, you sweat, words go missing. It is unpleasant, but it gives you feedback.

Alongside it, something else is happening. It does not hurt, it announces nothing, and it first speaks up in ten or twenty years. Which is exactly why it goes unaddressed.

Bone: the fastest loss is brief and it is now

Bone is rebuilt throughout life. In that process oestrogen acts as a brake on breakdown. When it falls away, the brake releases.

The timing is the interesting part. The loss is not spread evenly across old age. Studies place the fastest phase starting roughly a year before the final period and lasting about two to three years after it. In that window, bone in the lumbar spine is lost at somewhere around two per cent a year. The pace then slows, but what is lost in that window does not come back.

In practice this means the period when prevention pays off most overlaps with the period when most women have entirely different things on their minds.

Heart: an advantage that does not hold

Until menopause, women have a lower risk of heart and vascular disease than men of the same age. After menopause that gap closes.

Specific numbers shift in the same period. Studies that follow women over time describe total and LDL cholesterol rising through the transition independently of age, blood pressure tending to rise, and fat distribution shifting towards visceral fat around the abdomen, which is the metabolically most active kind.

And one more thing that surprises almost everyone. The leading cause of death in women is cardiovascular disease, not breast cancer. That is not an argument for fear. It is an argument for not meeting your own blood pressure for the first time at sixty.

The numbers worth knowing

This is not a list to have tested all at once. It is a list worth discussing with a doctor.

  • Blood pressure. The cheapest and highest-yield number there is. A home monitor and a week of readings say more than a single measurement in a surgery.
  • Lipid profile. Total cholesterol, LDL, HDL and triglycerides. What is useful is the trend over time, not a one-off value.
  • Fasting glucose, or HbA1c. Insulin resistance builds quietly in this period.
  • Waist circumference. Not an elegant measure, but it says more about visceral fat than the scales do.
  • Vitamin D. At our latitudes deficiency is common and it matters for bone.
  • TSH. The thyroid can imitate a large share of menopause symptoms.
  • Bone density scan (DXA). A caveat here. Not every woman needs one automatically at fifty. It is indicated on the basis of risk factors, and fracture risk is estimated with tools such as FRAX. Whether it is appropriate is a decision for a doctor.

Risk factors worth raising yourself: a hip fracture in your mother, menopause before forty-five, low body weight, smoking, long-term corticosteroid use, a past eating disorder, coeliac disease or another condition that impairs absorption.

What actually makes a difference

  • Strength training. Bone responds to load. Walking is good for the heart, but for bone it is a weak signal. Two or three short resistance sessions a week do work that nothing else substitutes for.
  • Protein. Bone is not only calcium. It is also a collagen matrix and the muscle that pulls on it.
  • Calcium and vitamin D. From food first. Supplements make sense where intake falls short, not blindly.
  • Smoking and alcohol. Both worsen bone and vessels, and with both it adds up.
  • Sleep. It affects blood pressure, appetite and your capacity to train. It is not a separate category, it is the precondition for the rest.
  • Balance. A fracture is usually the result of a fall, not of weak bone alone. Ten minutes on one leg while brushing your teeth is legitimate training.
  • Hormone therapy. For bone the protective effect is well documented. For the heart it is more nuanced and depends mainly on age and on how long it has been since menopause. That is a conversation with a doctor, not a decision made from the internet.

What gets sold and does not work

Collagen drinks as osteoporosis prevention, alkaline diets meant to stop calcium leaching from bone, and detoxes meant to clean out your arteries. For none of them is there evidence that they do what they promise. What they cost over two years would buy dumbbells and an honest annual protein budget.

Longevity is decided in the very period most women spend in symptom-firefighting mode.

This is information, not medical advice. Decisions about tests and treatment belong to a doctor.
