Menopause and Long-Term Health: What Happens to Bones, Heart and Body Composition
Hot flushes end. Most last a few years, some longer, and eventually the thermostat settles. What does not end is what happens to bone, to arteries and to where the body stores fat. Those changes begin during the transition, continue quietly for decades, and are the reason menopause matters medically long after the symptoms have faded.
This is the part that tends to get skipped, partly because there is nothing to feel. Bone loss is silent until a fracture. Rising cholesterol is silent until it is measured. Both are more treatable than either would be twenty years later, which makes the years around the final period an unusually valuable window.
For the symptoms themselves — flushes, sleep, dryness, mood — see our separate guide to menopause symptom relief. This one is about the long game.
🦴 Bone: the five years that matter most
Oestrogen restrains the cells that break bone down. When it falls, those cells outpace the cells that build bone, and the balance tips.
| Period | Rate of bone loss |
|---|---|
| Before menopause | Around 0.5 percent per year after the mid-thirties |
| The year before to four years after the last period | Up to 2 percent per year at the spine |
| Later postmenopause | Around 1 percent per year, continuing indefinitely |
Across the decade spanning menopause, women lose roughly 10 to 20 percent of bone mass. That loss is not recovered later, which is why prevention during the transition is worth more than treatment afterwards.
📏 Reading a bone density scan. A DEXA scan gives a T-score, comparing bone density with a healthy young adult. Above −1.0 is normal. Between −1.0 and −2.5 is osteopenia, meaning reduced density but not disease. At or below −2.5 is osteoporosis. Each point lower roughly doubles fracture risk. A separate tool, FRAX, combines density with age, weight, smoking, steroid use and family history to give a ten-year fracture probability, and that number rather than the T-score alone is what usually decides whether to treat.
Scanning is generally offered to all women at 65, earlier where there are risk factors: early menopause before 45, a parent who fractured a hip, a body weight under about 58 kg, smoking, more than two alcoholic drinks a day, long-term steroid use, rheumatoid arthritis, coeliac disease or an overactive thyroid. Any fracture from a minor fall after 50 counts as a fragility fracture and warrants assessment regardless of age.
🥛 The foundation: calcium, vitamin D and load
- Calcium, 1000 to 1200 mg daily
- Preferably from food. Dairy, tinned fish with bones, fortified plant milks, tofu, leafy greens and almonds. Supplements are for filling a genuine gap, not for adding on top of an adequate diet; taking more than needed does not build more bone and has been linked in some analyses to cardiovascular concern.
- Vitamin D, 800 to 1000 IU daily
- Without it calcium is poorly absorbed. Deficiency is common at higher latitudes and in anyone who covers up or stays indoors, and it is worth measuring rather than guessing.
- Weight-bearing and resistance exercise
- Bone responds to load, so walking, stair climbing, dancing and jumping stimulate it while swimming and cycling do not. Resistance training two or three times a week is the most effective single measure and also protects muscle.
- Balance training
- Underrated and arguably the most important. Hips break because people fall. Tai chi, single-leg work and anything that challenges stability reduce falls measurably.
- Protein, 1.0 to 1.2 g per kg of body weight
- Bone is a protein scaffold with mineral in it, and muscle protects bone. Older women frequently eat well below this.
- Stopping smoking
- Smoking accelerates bone loss directly and brings menopause forward by one to two years.
💊 Medication for bone, and how each is used
Treatment is considered at a T-score of −2.5 or below, after a fragility fracture, or where FRAX puts ten-year risk above the local threshold. In our women's health category the relevant options are a bisphosphonate and a SERM.
🔹 Alendronate
Fosamax (Alendronate 10/35/70 mg) binds to bone surfaces and switches off the cells that resorb it. It reduces vertebral and hip fractures by roughly 40 to 50 percent. How it is taken matters more than with almost any other tablet:
- 📅 70 mg once weekly, the same day each week, or 10 mg daily
- 🌅 First thing in the morning, on an empty stomach, with a full glass of plain water. Not coffee, not juice, not mineral water
- 🧍 Stay upright and eat nothing for 30 minutes. Lying down risks the tablet lodging in the oesophagus and causing ulceration, which is the main reason people stop
- ⏳ Calcium, iron and antacids wait at least two hours, because they block absorption completely
- 🦷 A dental check before starting is sensible, because of the rare risk of osteonecrosis of the jaw, which is far more common with intravenous treatment in cancer than with tablets for osteoporosis
- 📆 A drug holiday is considered after five years in lower-risk women, since the drug persists in bone and continuing indefinitely raises the small risk of atypical thigh fractures
🔹 Raloxifene
Evista (Raloxifene 60 mg) is a selective oestrogen receptor modulator: it acts like oestrogen on bone and against oestrogen in breast tissue. It reduces spinal fractures and also reduces the risk of oestrogen-receptor-positive breast cancer, which makes it a considered choice for a woman with both concerns.
Its limitations are specific. It does not reduce hip fractures. It makes hot flushes worse, so it suits women past that stage. And it raises the risk of venous thrombosis, so it is avoided in anyone with a clot history or prolonged immobility.
⚖️ Where hormone therapy fits for bone. Oestrogen prevents bone loss effectively and reduces fractures, and for a woman under 60 who is taking it for symptoms anyway, bone protection comes free. What changed over the last two decades is that it is no longer started purely for bone in older women, where a bisphosphonate does the same job without the other considerations. Timing is the whole argument.
❤️ The heart: the risk curve changes direction
Before menopause, women have substantially less coronary disease than men of the same age. Within a decade afterwards the gap closes. Some of that is ageing, and a measurable part is the loss of oestrogen, which affects the vessel lining, lipid handling and blood pressure regulation.
| What changes | Direction |
|---|---|
| LDL cholesterol | Rises, often sharply in the year around the final period |
| HDL cholesterol | Stays similar in quantity but becomes less protective in function |
| Triglycerides | Rise |
| Blood pressure | Rises, and hypertension becomes more common than in men of the same age |
| Insulin sensitivity | Falls, raising type 2 diabetes risk |
| Visceral fat | Increases, independently of total weight |
The practical conclusion is short: this is the moment to have lipids, blood pressure and glucose measured, and to treat what is found. A woman who reaches 55 with untreated high blood pressure and an LDL that rose unnoticed at 50 has lost five years of prevention.
⏰ The timing hypothesis, in one paragraph. The trial results that frightened a generation away from hormone therapy came largely from women who started it in their late sixties, an average of twelve years after menopause, when arteries already had plaque. Analyses by age since show a different picture in women who start under 60 or within ten years of their last period: cardiovascular effects are neutral or favourable in that group. Oestrogen appears to protect healthy vessels and destabilise diseased ones. It is not a reason to take hormone therapy for the heart, and it is a reason not to assume it damages it.
📏 Body composition: it is not what most people think
Women gain on average about half a kilogram a year through midlife. Careful studies attribute most of that to ageing and reduced activity rather than to menopause itself.
What menopause reliably changes is not how much fat there is but where it sits. Fat storage shifts from hips and thighs to the abdomen, and specifically to visceral fat around the organs. That matters because visceral fat is metabolically active: it drives insulin resistance, inflammation and the lipid changes above. A woman whose weight has not changed at all can have a measurably worse metabolic profile than five years earlier.
Alongside it, muscle mass falls at around 1 percent a year, which lowers resting energy use and makes the same diet gain weight. The two measures that address both:
- 💪 Resistance training two or three times a week — the only intervention that reverses muscle loss, and it protects bone at the same time
- 🥩 Enough protein, spread through the day rather than concentrated in the evening
- 📐 Measure the waist, not just the scale. Above 80 cm indicates raised risk and above 88 cm high risk, regardless of what the weight says
😴 Two things that get missed after menopause
- Sleep apnoea
- Risk rises substantially after menopause, partly from the loss of progesterone, which stimulates breathing. It is badly underdiagnosed in women because it presents as fatigue, insomnia and low mood rather than loud snoring. Anyone exhausted despite adequate time in bed, with morning headache or witnessed pauses in breathing, deserves assessment.
- Genitourinary symptoms
- Unlike hot flushes, vaginal dryness and urinary symptoms are progressive. They do not resolve with time; they worsen. Low-dose vaginal oestrogen such as Vagifem (Vaginal Estradiol 25 mcg) acts locally with minimal systemic absorption and can be continued long term. Treating early is easier than treating atrophy that has been established for a decade.
Worth ruling out too: an underactive thyroid produces fatigue, weight gain, low mood and cold intolerance that overlap almost completely with menopause, and it becomes more common with age. A single blood test separates them.
🚨 Symptoms that need investigation, not reassurance
- 🚩 Any vaginal bleeding after twelve months without a period. This is never dismissed as menopause. It needs assessment to exclude endometrial cancer, which is highly curable when caught early
- Losing more than 4 cm of height, or new upper back curvature, which suggests vertebral fractures that were never diagnosed
- A fracture from a minor fall after the age of 50
- Sudden severe back pain without injury
- Chest pain, breathlessness on exertion or unusual fatigue — heart disease in women presents less typically than in men and is diagnosed later as a result
- A breast lump, skin change or nipple discharge
- Persistent bloating, early fullness or pelvic pain, which are the vague symptoms of ovarian cancer
- Menopause before 45, which needs its own assessment and usually needs hormone replacement until the average age of menopause for bone and cardiovascular protection
❓ Frequently asked questions
How much bone do women lose after menopause?
Roughly 10 to 20 percent of bone mass across the decade spanning menopause, with the fastest loss of up to 2 percent a year at the spine in the year before and four years after the final period. That loss is not regained later.
What does a T-score of minus 2 mean?
That is osteopenia: reduced bone density but not osteoporosis, which starts at minus 2.5. Each whole point lower roughly doubles fracture risk. Whether to treat usually depends on a FRAX ten-year risk calculation rather than the T-score alone.
When should I have a bone density scan?
Generally at 65, or earlier with risk factors such as menopause before 45, a parent who fractured a hip, low body weight, smoking, long-term steroids or rheumatoid arthritis. Any fracture from a minor fall after 50 warrants a scan at any age.
How do I take alendronate correctly?
Seventy milligrams once weekly, first thing in the morning on an empty stomach with a full glass of plain water, then stay upright and eat nothing for 30 minutes. Calcium, iron and antacids wait at least two hours. Lying down risks oesophageal ulceration.
How much calcium and vitamin D do I need?
Around 1000 to 1200 mg of calcium daily, preferably from food, and 800 to 1000 IU of vitamin D. Supplements fill a genuine gap; taking more calcium than needed does not build extra bone.
Which exercise protects bone?
Weight-bearing activity such as walking, stairs, dancing and jumping, plus resistance training two or three times a week. Swimming and cycling do not load bone. Balance work matters as much, because hips break as a result of falls.
Does menopause cause weight gain?
Mostly no. The half kilogram a year women gain through midlife is largely ageing and reduced activity. What menopause changes is where fat is stored, shifting from hips and thighs to visceral fat around the organs, which drives insulin resistance and lipid changes even at unchanged weight.
Does menopause raise cholesterol?
Yes. LDL and triglycerides rise, often sharply around the final period, HDL becomes less protective in function, and blood pressure and insulin resistance increase. This is the point at which lipids, blood pressure and glucose are worth measuring.
Is hormone therapy bad for the heart?
The alarming trial results came mainly from women starting it in their late sixties, long after menopause. In women who start under 60 or within ten years of their last period, cardiovascular effects are neutral or favourable. It is not taken for heart protection, but the blanket fear is not supported.
I bled once, two years after my last period. Does it matter?
Yes, always. Any bleeding after twelve months without a period needs assessment to exclude endometrial cancer, which is highly curable when found early. It is never attributed to menopause without investigation.
