Osteoporosis in Older Adults: What They Can and Can't Do
Osteoporosis in older adults: the exercises to avoid (not just high-impact), bone-building foods, DEXA testing, and how to take bone medication safely.

ElderHearth offers general information, not medical advice. Bone-density testing, exercise limits, and medication choices are individual. Always work with your parent's doctor, and ideally a physical therapist, before changing exercise or any medication.
Because osteoporosis in older adults has no symptoms until a bone breaks, it is easy to treat it as nothing until the day it becomes everything: a fractured hip or spine that changes a parent's independence overnight. This guide covers what a parent with osteoporosis can and can't do, from the exercise that builds bone to the movements that quietly raise fracture risk, plus the foods, the testing, and the medication that actually works. It comes with a twist most families never hear: the danger is not only high-impact activity. Some of the everyday "healthy" movements, bending forward to touch the toes, sit-ups, certain yoga poses, can crack a fragile spine, so safe movement in later life takes a little knowing.
The short version: an older adult with osteoporosis should stay active with weight-bearing and strengthening exercise and good balance work, get enough calcium, vitamin D, and protein, and, above all, fall-proof the home, because a fracture takes a fall meeting a fragile bone. What they should avoid is high-impact pounding and, importantly, loaded forward bending and twisting of the spine. If a doctor prescribes a bone medication like a bisphosphonate, taking it correctly, upright and on an empty stomach, matters as much as taking it at all.
What osteoporosis in older adults is, and why it's silent
Osteoporosis means bones have lost density and become fragile, so they break far more easily, sometimes from a minor fall or bump. The danger is that you cannot feel it happening. There is usually no pain or warning until a bone fractures, which is why finding it early, before the fall that tests those bones, matters so much. A broken hip in later life is not a small event: it often marks the end of independent living, which is exactly why the quiet, preventable steps in this guide carry so much weight.
Who should get a bone density (DEXA) test
Osteoporosis is diagnosed with a DEXA scan, a quick, painless X-ray of bone density. The U.S. Preventive Services Task Force recommends:
- Women: start screening at age 65 (earlier if there are added risk factors).
- Men: no formal screening guideline, but it is reasonable to ask the doctor about testing around age 70, or after any low-impact fracture.
If your parent has broken a bone from a minor fall, ask about a DEXA scan regardless of age.
What a T-score means
A DEXA result is reported as a T-score, which compares your parent's bone density to a healthy young adult:
| T-score | What it means |
|---|---|
| -1.0 or above | Normal bone density |
| Between -1.0 and -2.5 | Osteopenia (low bone mass) |
| -2.5 or lower | Osteoporosis |
Knowing the number turns a vague worry into a clear plan, and it is what a doctor uses, along with the FRAX fracture-risk tool, to decide whether medication is worth it.
What exercise can an older adult with osteoporosis do, and what should they avoid?
Exercise is one of the best things for fragile bones, but osteoporosis is the condition where the wrong exercise can do harm, so this is worth getting right. The goal is threefold: build bone, build the muscle and balance that prevent falls, and protect the spine while doing it.
What helps:
- Weight-bearing activity like walking, which signals bone to stay strong.
- Strength or resistance training a couple of times a week, one of the most effective ways to maintain bone and muscle.
- Balance and posture work like tai chi, which lowers fall risk, the real trigger of most fractures.
- Back-strengthening (extension) exercises, done gently, which support an upright posture and the spine.
What to avoid, and the part that surprises people: beyond high-impact pounding (jumping, running on hard surfaces), a parent with osteoporosis, especially anyone who has already had a spine fracture, should avoid loaded forward bending and twisting of the spine. Most spinal fractures happen in a forward-bent position, so the movements to skip include sit-ups and crunches, toe-touches, and the deep forward folds and twists in some yoga and Pilates routines, particularly while holding a weight. The safer swap is to keep the spine tall: strengthen the core with movements that do not curl it forward, and bend at the hips and knees, not the waist, when lifting. Because the right line between helpful and harmful depends on how fragile the bones are, a few sessions with a physical therapist are genuinely worth it here.
What foods build bone, and what should an older adult limit?
Diet is the daily foundation, and for bone it comes down to three nutrients: calcium, vitamin D (which lets the body absorb calcium), and enough protein.
| Bone-building | Best to limit |
|---|---|
| Dairy, or fortified plant milks and juices | Excess alcohol (more than about two drinks a day) |
| Leafy greens, broccoli, canned fish with soft bones | Very high sodium, which pulls calcium out in urine |
| Beans, nuts, tofu, fortified cereals | Heavy caffeine in large amounts |
| Enough protein at each meal (bone is not just minerals) | Smoking, which directly weakens bone |
The Bone Health and Osteoporosis Foundation recommends that adults 50 and older get roughly 1,000 to 1,200 mg of calcium and 800 to 1,000 IU of vitamin D a day, counting food and supplements together, though the right amount is individual and worth confirming with the doctor. Food first is the usual advice; very high-dose calcium supplements are not better and can carry their own risks, so more is not the goal, enough is.
Treating osteoporosis in older adults, and the right way to take the medication
Beyond calcium, vitamin D, and exercise, doctors can prescribe medication when fracture risk is high. Bisphosphonates are the usual first-line treatment, and they work:
- They reduce spinal fractures by roughly 40 to 60 percent (depending on the drug) and hip fractures by roughly 40 percent (up to about half in those at highest risk).
- They come as a weekly or monthly pill, or a once-a-year IV infusion.
- A common approach is about five years of oral treatment (or three years of the yearly IV), then a reassessment, sometimes a "drug holiday," with the doctor.
Two serious side effects, osteonecrosis of the jaw and atypical femur fractures, get a lot of attention but are exceedingly rare, and the femur-fracture risk mainly rises with use beyond about five years. For the vast majority at real fracture risk, the benefit far outweighs it.
There is a practical part families miss. Oral bisphosphonates (like alendronate) can irritate or ulcerate the esophagus if taken incorrectly, so how they are taken matters:
- Take it first thing in the morning on an empty stomach, with a full glass of plain water (not coffee, juice, or mineral water).
- Stay upright, sitting or standing, for at least 30 to 60 minutes afterward, and do not eat, drink anything else, or take other pills during that window.
For an older parent, this is a spot where a caregiver's help keeps a good medication from causing a painful problem. Keep it on the medication list with the instructions attached.
How can I help a parent with osteoporosis?
- Fall-proof the home first. This is the single highest-value move, because a fracture is a fragile bone meeting a fall. Grab bars, lighting, removing loose rugs, and clear paths do more than almost anything: see fall prevention for seniors, and know what to do if a parent falls.
- Get the exercise right, not just more. Encourage walking, strength, and balance work, and gently steer away from toe-touches, sit-ups, and deep spinal bends. A physical therapy referral is worth asking for.
- Handle the medication carefully. If your parent takes an oral bisphosphonate, help them take it upright, on an empty stomach, with plain water, and confirm they are getting enough calcium and vitamin D.
- Keep the food simple and bone-friendly, with calcium, vitamin D, and protein at meals, and watch heavy alcohol and smoking.
- Track the testing. Make sure a due DEXA scan happens, and bring the T-score and medication plan to appointments.
Osteoporosis rarely travels alone. The same care overlaps with arthritis and the wider work of bone and joint health, so a plan that covers movement, nutrition, and fall safety protects a parent on several fronts at once.
What an older adult with osteoporosis can and can't do
| Can do | Should avoid |
|---|---|
| Walk, do resistance training, tai chi for balance | High-impact jumping or running on hard surfaces |
| Strengthen the core keeping the spine tall | Sit-ups, toe-touches, and loaded forward bending |
| Bend at the hips and knees to lift | Twisting and bending the spine under load |
| Get enough calcium, vitamin D, and protein | Heavy alcohol, smoking, and mega-dose calcium |
| Take a bisphosphonate upright, on an empty stomach | Lying down soon after an oral bisphosphonate |
| Fall-proof the home as the top priority | Treating fall risk as separate from bone health |
Frequently Asked Questions
What exercises should you avoid with osteoporosis? Avoid high-impact activities (jumping, running on hard surfaces) and, importantly, movements that bend or twist the spine forward under load, such as sit-ups, crunches, toe-touches, and deep forward folds or twists in some yoga and Pilates routines. Most spinal fractures occur in a forward-bent position. Safer choices keep the spine tall: walking, resistance training, balance work, and gentle back-strengthening. A physical therapist can tailor this to how fragile the bones are.
What is a normal bone density T-score? A T-score of -1.0 or above is normal. Between -1.0 and -2.5 is osteopenia (low bone mass), and -2.5 or lower is osteoporosis.
Who should get a bone density test? Women should start at age 65 (earlier with risk factors). Men can ask about testing around 70. Anyone who breaks a bone from a minor fall should be tested regardless of age.
How do you take alendronate or other bisphosphonates safely? Take it first thing in the morning on an empty stomach, with a full glass of plain water, then stay upright (sitting or standing) for at least 30 to 60 minutes without eating, drinking anything else, or taking other pills. This prevents the esophagus irritation these drugs can cause when taken incorrectly.
How well does osteoporosis treatment work? First-line bisphosphonates reduce spinal fractures by roughly 40 to 60 percent depending on the drug, and hip fractures by about 40 percent (up to roughly half in the highest-risk patients), taken as a pill or a yearly infusion.
A last word
Osteoporosis in older adults is the rare health problem you can often stay ahead of, because nearly everything that protects a parent is within reach: test for it, then keep them moving in the ways that build bone while steering clear of the forward bends that break it, feed the bones well, take any medication correctly, and above all fall-proof the home so strong-enough bones are never put to a hard test. Get those pieces right and osteoporosis usually stays what it should be, a manageable background condition rather than the fracture that ends aging safely at home.
