Osteoporosis: Symptoms, Causes & How to Manage It

Everything you need to know about protecting your bones, slowing bone loss, and living well with osteoporosis — backed by evidence-based guidance.

When Linda, 58, tripped over her dog’s leash and fractured her wrist in two places, her orthopedic surgeon delivered an unexpected verdict: the break wasn’t just from the fall — her bones had become dangerously fragile. A follow-up bone density scan confirmed what Linda had no idea was happening inside her body. She had osteoporosis.

Linda’s story is far from unusual. According to the National Institutes of Health (NIH), approximately 10 million Americans have osteoporosis, and another 44 million have low bone density — putting them at significantly higher risk of fractures. Yet because osteoporosis develops silently, without pain or obvious symptoms, most people don’t realize they have it until a bone breaks.

If you’re over 35 — especially if you’re a woman approaching or past menopause — understanding osteoporosis isn’t optional. It’s essential. In this guide, you’ll learn what osteoporosis really is, what causes it, how to recognize warning signs early, and what evidence-based steps you can take to protect your bones starting today.

What Is Osteoporosis? Understanding the Basics

Osteoporosis is a chronic bone disease in which the density and quality of bone are reduced. The word itself comes from Greek and Latin roots meaning "porous bones" — and that’s exactly what happens. Healthy bone looks like a dense honeycomb under a microscope. With osteoporosis, the holes in that honeycomb grow larger, making bones lighter, less dense, and far more prone to fracturing.

Your skeleton is a living organ. Specialized cells called osteoblasts constantly build new bone, while osteoclasts break down old bone — a process called bone remodeling. In young adulthood, bone formation outpaces bone loss. Most people reach peak bone mass around age 30. After that, the balance gradually shifts, and bone loss begins to outpace bone formation.

When that imbalance becomes severe enough, osteoporosis develops. The bones most commonly affected are the hip, spine (vertebrae), and wrist — the three sites most vulnerable to fractures from even minor falls or, in severe cases, everyday activities like bending or lifting a grocery bag.

According to the CDC, osteoporosis is responsible for more than 2 million bone fractures every year in the United States. Hip fractures are particularly serious: the National Osteoporosis Foundation reports that roughly 20% of seniors who suffer a hip fracture die within one year due to complications. Osteoporosis is not just a quality-of-life issue — it’s a life-threatening condition.

Signs and Symptoms: How Osteoporosis Shows Up

One of the most challenging aspects of osteoporosis is that it earns its reputation as a "silent disease." In most cases, there are no symptoms in the early stages. You won’t feel your bones thinning. By the time a fracture occurs, the disease has often been progressing for years — sometimes decades.

That said, there are warning signs you should never ignore:

• Back pain — often caused by a fractured or collapsed vertebra in the spine
• Loss of height over time — even a half-inch reduction can signal vertebral compression fractures
• A stooped or hunched posture (called kyphosis or "dowager’s hump") — caused by spinal compression
• Fractures that occur more easily than expected — breaking a bone from a fall that wouldn’t normally cause one
• Receding gums — jawbone density loss may be an early indicator, according to research from the NIH
• Weakened grip strength — studies suggest grip strength correlates with overall bone density

A landmark study published in the Journal of Bone and Mineral Research found that vertebral fractures — the most common osteoporotic fracture — go undiagnosed in up to 70% of cases because they often produce only mild or vague back pain. Many people assume they’ve simply strained a muscle.

If you’ve noticed any of these signs, or if you’re in a higher-risk group (more on that below), talk to your doctor about a bone density test called a DEXA scan (dual-energy X-ray absorptiometry). It’s quick, painless, and considered the gold standard for diagnosing osteoporosis.

Causes and Risk Factors: Who Is Most Vulnerable

Osteoporosis doesn’t have a single cause. It develops from a combination of factors — some you can control, and some you can’t. Understanding both categories helps you focus your energy where it matters most.

Non-modifiable risk factors include:

• Age — bone loss accelerates after age 50, especially in women after menopause
• Sex — women are four times more likely to develop osteoporosis than men, according to the NIH
• Family history — if a parent or sibling had osteoporosis or a hip fracture, your risk increases significantly
• Body frame — small-boned, slender individuals tend to have less bone mass to draw from as they age
• Ethnicity — white and Asian women face the highest risk, though osteoporosis affects all racial groups

Modifiable risk factors — things you can change — include:

• Low calcium and vitamin D intake — both are essential for bone formation; the NIH recommends 1,000–1,200 mg of calcium and 600–800 IU of vitamin D daily for adults over 50
• Physical inactivity — sedentary lifestyles accelerate bone loss
• Smoking — tobacco use directly interferes with the body’s ability to absorb calcium
• Excessive alcohol consumption — more than two drinks per day reduces bone formation
• Long-term use of corticosteroids — medications like prednisone are among the most common drug-related causes of bone loss
• Hormonal imbalances — low estrogen in women (especially after menopause) and low testosterone in men both accelerate bone loss
• Eating disorders or malnutrition — chronic nutrient deficiencies deplete bone reserves

It’s also worth noting that certain chronic conditions — including rheumatoid arthritis, celiac disease, inflammatory bowel disease, and chronic kidney disease — can increase your osteoporosis risk. If you’re managing any of these conditions, ask your doctor whether your bone health needs closer monitoring. You can learn more about how chronic kidney disease may affect your bone health in our article on Chronic Kidney Disease: Symptoms, Causes & Management.

Evidence-Based Treatment Options: What You Can Actually Do

The good news is that osteoporosis is manageable — and in many cases, preventable. Whether you’ve already been diagnosed or you’re working to protect your bone health proactively, here’s what the evidence supports.

1. Optimize Your Calcium and Vitamin D Intake

Calcium is the primary building block of bone. Vitamin D is what allows your body to absorb and use calcium effectively. Without adequate vitamin D, your body absorbs as little as 10-15% of the calcium you consume, according to the NIH.

The best dietary sources of calcium include dairy products (milk, yogurt, cheese), fortified plant milks, leafy greens like kale and bok choy, canned sardines and salmon (with bones), and tofu made with calcium sulfate. For vitamin D, focus on fatty fish, egg yolks, fortified foods, and sensible sun exposure. Many adults over 50 benefit from supplementation — but talk to your doctor before starting, as excess calcium supplementation has been linked to kidney stones and, in some research, cardiovascular concerns.

2. Prioritize Weight-Bearing and Resistance Exercise

Exercise is one of the most powerful tools for bone health — but not all exercise is equal. Weight-bearing activities, where your bones support your body weight, stimulate bone formation. The American College of Sports Medicine recommends a combination of weight-bearing aerobic exercise (walking, hiking, dancing, stair climbing) and resistance training (lifting weights, resistance bands) for adults at risk of osteoporosis.

Research published by the Mayo Clinic confirms that regular resistance training can increase bone density in the spine and hip — even in adults over 60. Aim for at least 30 minutes of weight-bearing activity most days of the week, plus two to three resistance training sessions per week.

Balance exercises like tai chi and yoga also reduce fall risk — a critical priority when your bones are fragile. Studies suggest tai chi can reduce fall rates by up to 47% in older adults.

3. Quit Smoking and Limit Alcohol

If you smoke, quitting is one of the most impactful things you can do for your bone health — and every other aspect of your health. According to the American Academy of Orthopaedic Surgeons, smokers have significantly lower bone density than nonsmokers, and fractures in smokers heal more slowly. Limiting alcohol to no more than one drink per day for women and two for men also helps preserve bone density over time.

4. Explore Medication Options With Your Doctor

For people with diagnosed osteoporosis or very low bone density, lifestyle changes alone may not be enough. Several FDA-approved medications can slow bone loss or even build new bone:

• Bisphosphonates (alendronate, risedronate, zoledronic acid) — the most commonly prescribed class; they slow bone breakdown and reduce fracture risk by 30-50%, according to clinical trial data reviewed by the NIH
• Denosumab (Prolia) — a biologic injection given every six months that inhibits bone breakdown
• Teriparatide or abaloparatide — anabolic (bone-building) agents for people with very high fracture risk
• Hormone therapy — estrogen replacement can preserve bone density in menopausal women, though the risks and benefits must be carefully weighed with your doctor
• Romosozumab (Evenity) — a newer dual-action drug approved by the FDA that both builds bone and reduces breakdown, reserved for high-risk patients

The right treatment depends on your bone density scores, fracture history, overall health, and individual risk profile. This is a decision best made in close partnership with your physician or an endocrinologist who specializes in metabolic bone disease.

Maintaining overall health is also part of bone care — and habits like consistent sleep and managing chronic stress play a meaningful supporting role. Learn how daily habits for healthy aging after 40 can help you build a lifestyle that supports your bones and your overall wellbeing.

5. Fall Prevention: A Critical but Overlooked Priority

Treating bone density is only half the equation. Preventing falls is equally important. Practical steps include removing tripping hazards at home (loose rugs, clutter), installing grab bars in bathrooms, improving lighting, wearing supportive footwear, having regular vision and hearing check-ups, and reviewing medications with your doctor — since some drugs, including sedatives, blood pressure medications, and antidepressants, can increase fall risk.

When to See a Doctor About Osteoporosis

Many people wait until after a fracture to get evaluated. Don’t be one of them. Earlier detection means more options and better outcomes.

Schedule a conversation with your doctor if:

• You are a woman aged 65 or older (the U.S. Preventive Services Task Force recommends routine bone density screening at this age)
• You are a postmenopausal woman under 65 with one or more risk factors
• You are a man over 70, or a man aged 50-69 with significant risk factors
• You’ve had a fracture after a minor injury at any age
• You’ve lost height (more than an inch) or developed a stooped posture
• You’ve been on corticosteroids (like prednisone) for three months or longer
• You have a medical condition known to affect bone density

What to tell your doctor: Come prepared with your family history of fractures, a list of all medications and supplements you take, and any symptoms you’ve noticed (back pain, height loss, etc.).

Tests and screenings to ask about: A DEXA scan measures bone mineral density and provides a T-score, which tells you how your bone density compares to a healthy young adult. A T-score of -2.5 or lower indicates osteoporosis. Your doctor may also order blood tests to assess calcium, vitamin D, and hormonal levels, and may use the FRAX tool — a clinically validated calculator from the World Health Organization — to estimate your 10-year fracture risk.

It’s also worth noting that osteoporosis treatment is not a one-time event. Most medications require long-term monitoring, and some (particularly bisphosphonates) may need to be paused after several years. Staying in regular communication with your healthcare provider is essential.

Frequently Asked Questions About Osteoporosis

Can osteoporosis be reversed?
Osteoporosis cannot be fully "reversed," but bone density can be improved with treatment. Certain anabolic medications like teriparatide and romosozumab have been shown to meaningfully increase bone density over time, and lifestyle changes can slow or halt bone loss. The goal is to reduce fracture risk and preserve quality of life — and that’s absolutely achievable.

Is osteoporosis only a women’s disease?
No — though it’s far more common in women, about 2 million American men have osteoporosis, and another 12 million are at risk, according to the NIH. Men are often undertreated because osteoporosis in men is underdiagnosed. Low testosterone, long-term corticosteroid use, and excessive alcohol are leading causes in men.

How much calcium do I really need, and should I take supplements?
Most adults over 50 need 1,200 mg of calcium per day. Food sources are always preferable to supplements when possible, as whole foods provide additional nutrients and may carry fewer risks. If you can’t meet your calcium needs through diet alone, your doctor may recommend a supplement — typically calcium citrate (better absorbed, especially if you take acid-reducing medications) or calcium carbonate (most common, best taken with food). Always discuss supplement dosing with your healthcare provider.

Does walking help osteoporosis?
Yes — walking is a weight-bearing activity that stimulates bone formation and helps maintain bone density. However, walking alone may not be sufficient for people with significant bone loss. Combining brisk walking with resistance training and balance exercises provides the most comprehensive benefit, according to guidelines from the National Osteoporosis Foundation.

What’s the difference between osteoporosis and osteopenia?
Osteopenia refers to lower-than-normal bone density that hasn’t yet reached the threshold for osteoporosis. It’s essentially an early warning sign. People with osteopenia have a T-score between -1.0 and -2.5. While not all cases of osteopenia progress to osteoporosis, a diagnosis is a clear signal to take bone health seriously through lifestyle changes and, in some cases, medication. Think of it as a valuable window of opportunity.

Conclusion: Your Bones Deserve Attention Now, Not Later

Osteoporosis is one of the most common — and most preventable — chronic conditions affecting Americans over 50. The challenge is that it develops quietly, without obvious symptoms, until a fracture changes everything. The opportunity is that there are real, effective steps you can take right now to protect your bones.

Whether you’re optimizing your calcium and vitamin D intake, adding resistance training to your weekly routine, asking your doctor about a DEXA scan, or managing an existing diagnosis with medication, every action you take is an investment in your independence, mobility, and long-term health.

You don’t have to wait for a broken bone to start caring about your skeleton. The best time to protect your bone health is before a fracture happens — and that time is now.
