How do I improve bone density?
Weight-bearing exercise (walking, jogging, dancing), resistance training, calcium 700 mg/day and vitamin D 10 mcg/day support bone density. If your FRAX score is high, your GP may prescribe bisphosphonates.
Medically reviewed · Louis Maxwell, HCPC PH128483 Updated 11 September 2026Can you have osteoarthritis and osteoporosis at the same time?
Yes — they are different conditions but often coexist, especially in post-menopausal women. Osteoarthritis affects joint cartilage; osteoporosis weakens bones. Dual management focuses on calcium (700–1,200 mg/day), vitamin D, weight-bearing exercise, strength training and DEXA screening when appropriate.Medically reviewed by Maxwell

1. Osteoporosis vs osteoarthritis: what is the difference?
Osteoarthritis is a joint disease: cartilage thins, bones rub, pain and stiffness follow. Osteoporosis is a bone disease: bones lose density and become fragile, raising fracture risk — often silently until a fall.
2. Symptoms and risk factors
Osteoporosis is often called a "silent" condition because there are usually no symptoms until a fracture happens — most commonly in the wrist, hip or spine. Gradual loss of height, a stooped or curved upper back, and unexplained back pain from a spinal compression fracture can be later warning signs.
Key risk factors include being female and post-menopausal, a family history of hip fracture, low body weight, smoking, high alcohol intake, long-term oral steroid use, early menopause, and reduced mobility from another condition. Some inflammatory arthritis conditions also raise risk independently of steroid use.
3. Why arthritis and weak bones often occur together
Pain reduces activity, and inactivity weakens bones. Steroid medications used in inflammatory arthritis directly reduce bone density. Post-menopausal oestrogen loss accelerates both conditions. Sarcopenia and low body weight magnify the risk.
4. Calcium, vitamin D, magnesium: the mineral strategy
- Calcium: 700–1,200 mg/day from dairy, fortified milks, sardines, leafy greens.
- Vitamin D: 10 µg/day October–March (NHS), or 25 µg/day if deficient.
- Magnesium: 300 mg/day (men), 270 mg/day (women) from nuts, seeds, wholegrains.
- Vitamin K2: emerging evidence; sources include fermented dairy, eggs.
5. Load-bearing exercise for bone and joint health
Bones respond to load. Walking, dancing, tai chi, stair climbing and progressive resistance training all stimulate bone formation. Aim for 30 minutes of weight-bearing activity most days plus 2 strength sessions weekly. Avoid high-impact loading on inflamed or already-damaged joints.
6. Screening, testing and when medication is needed
A DEXA scan measures bone mineral density. NICE recommends scanning post-menopausal women with risk factors, anyone on long-term steroids, and those with a fragility fracture. Treatment (bisphosphonates, denosumab, HRT) is considered when T-score is below -2.5 or after a fragility fracture.
7. Can bone density loss be reversed?
Bone loss can be slowed, partially rebuilt and fracture risk substantially reduced through the right combination of nutrition, weight-bearing exercise and, where clinically indicated, medication. Full reversal to youthful bone density isn't generally realistic, which is why earlier action — ideally before or around menopause — gives the best long-term outcome.
8. Bone health, falls and frailty: the bigger picture
Osteoporosis rarely causes a fall by itself — its real danger is turning a minor stumble into a serious fracture. That's why bone density is best managed alongside muscle strength and falls prevention, not in isolation.

Frequently asked questions
What is the difference between osteoporosis and osteoarthritis?
Osteoporosis weakens bones, raising fracture risk. Osteoarthritis wears the cartilage in joints, causing pain and stiffness. Both can co-exist but have different causes and treatments.
Can I have both at the same time?
Yes — and many post-menopausal women do. Hormonal change, reduced activity from joint pain, and shared risk factors mean dual diagnosis is common.
How much calcium do I need?
UK adults need 700 mg/day, rising to 1,200 mg/day for post-menopausal women and adults with osteoporosis. Sources include dairy, fortified plant milks, sardines, leafy greens and beans.
Is weight-bearing exercise safe with arthritis?
Yes, when prescribed correctly. Walking, dancing, stair climbing and graded resistance training stimulate bone without damaging joints. Avoid high-impact loading on already-painful joints.
When should I get a bone density scan?
NICE recommends DEXA scans for post-menopausal women under 65 with risk factors (low BMI, family history, fragility fracture, long-term steroids), and all women over 65.
Do I need bone medication?
Bisphosphonates and other treatments are recommended when DEXA T-score is below -2.5, or with a prior fragility fracture. Your GP or specialist will assess fracture risk using FRAX.
What are the symptoms of osteoporosis?
Osteoporosis is often called a "silent" condition because it typically has no symptoms until a fracture occurs — most commonly in the wrist, hip or spine. Loss of height over time, a stooped posture, or back pain from a spinal compression fracture can be later warning signs.
What are the main risk factors for osteoporosis?
Being female and post-menopausal, family history of fracture, low body weight, smoking, high alcohol intake, long-term steroid use, and conditions that reduce mobility all raise risk. Early menopause and some inflammatory arthritis conditions also increase risk independently.
How does osteoporosis connect to falls and frailty?
Osteoporosis itself does not cause falls, but it turns a minor fall into a serious fracture. That is why bone density, muscle strength and falls prevention are usually managed together in older adults — see our falls prevention and frailty guides below.
Can osteoporosis be reversed?
Bone density loss can be slowed, partially rebuilt, and fracture risk substantially reduced with the right combination of nutrition, weight-bearing exercise and, where indicated, medication — but full reversal to youthful bone density is not generally realistic. Early action gives the best results.
