Proton Pump Inhibitors and Osteoporosis: What You Need to Know About Fracture Risk
Nov, 18 2025
PPI Fracture Risk Assessment Tool
How This Tool Works
This tool estimates your risk of fractures related to proton pump inhibitor (PPI) use based on scientific evidence. It doesn't replace medical advice but helps you understand your personal risk factors.
Risk is based on factors like duration of use, dosage, age, gender, and other conditions. Results are approximate and should be discussed with your healthcare provider.

Additional Risk Factors
For millions of people, proton pump inhibitors (PPIs) are a daily lifeline-relieving heartburn, healing ulcers, and managing chronic acid reflux. But if you’ve been taking them for years, especially if you’re over 65 or postmenopausal, there’s a quiet question you should ask: Could this medication be weakening my bones?
The answer isn’t simple. PPIs don’t cause osteoporosis overnight. They don’t turn healthy bones brittle in a few months. But over time-especially with high doses and long use-there’s enough evidence to suggest a real, measurable link between these common acid blockers and a higher chance of fractures, particularly in the hip, spine, and wrist. It’s not a guarantee. But it’s a risk you can’t ignore if you’re on PPIs long-term.
How PPIs Work-and Why That Might Hurt Your Bones
PPIs like omeprazole, esomeprazole, and pantoprazole work by shutting down the stomach’s acid pumps. That’s great if you have GERD or an ulcer. But your stomach acid isn’t just there to digest food-it’s also essential for absorbing key minerals, especially calcium.
Most calcium supplements, like calcium carbonate, need stomach acid to dissolve properly. Without enough acid, your body can’t absorb it well. And if your bones aren’t getting enough calcium, they start to lose density. Over time, that’s osteoporosis. It’s not just calcium, either. PPIs may also interfere with magnesium and zinc absorption, both of which play roles in bone strength.
There’s another layer: long-term PPI use raises gastrin levels-a hormone that signals your stomach to make more acid. Higher gastrin may stimulate bone cells called osteoclasts, which break down bone tissue. Some research also suggests changes in histamine signaling could speed up bone loss. The science isn’t settled on every detail, but the pattern is clear: less acid, less mineral absorption, and possible direct effects on bone remodeling.
The Numbers Don’t Lie-But They’re Not Alarmist
Let’s talk numbers. A 2019 meta-analysis in the Journal of Bone and Mineral Research looked at 15 studies involving over 1 million people. It found that long-term PPI users had a 20-30% higher risk of hip and spine fractures compared to non-users. That sounds scary-until you put it in context.
For a healthy 60-year-old woman, the baseline risk of a hip fracture over five years is about 1 in 100. With long-term PPI use, that risk might go up to 1.3 in 100. Still low. But for someone with other risk factors-like being underweight, on steroids, or already diagnosed with osteoporosis-that extra 30% could mean the difference between staying mobile and needing surgery.
And it’s not just about duration-it’s about dose. Studies show that people taking high-dose PPIs (like 2 or more pills a day) have up to a 67% higher risk of hip fractures than those on low doses. One study found that after seven straight years of daily use, the risk of hip fracture jumped nearly fivefold. That’s not common-but it’s real.
Here’s what’s interesting: the same studies didn’t find the same risk with H2 blockers like famotidine or ranitidine. These drugs reduce acid too, but not as completely. That suggests it’s not just acid suppression-it’s the degree of suppression that matters.
Who’s Most at Risk?
Not everyone on PPIs needs to worry. The risk is concentrated in specific groups:
- Women over 65, especially postmenopausal
- People with low body weight (under 57 kg or 125 lbs)
- Those with a prior fracture history
- People taking corticosteroids, like prednisone
- Anyone on PPIs for more than a year at high doses
Men and younger people have lower risk-but it’s not zero. A 2020 study of children found a 22% higher risk of lower-limb fractures in those on PPIs long-term, though the absolute risk was still small. That means if you’re on these drugs for any reason, especially for years, you should know your risk profile.
What the Experts Say-And What They Don’t
The FDA issued a safety warning in 2010 after reviewing seven studies. Six showed a link between PPIs and fractures. One didn’t. The agency concluded the risk was real but modest-and only significant with long-term, high-dose use. They didn’t pull PPIs off the market. They just added a warning to labels.
Some researchers, like Dr. Leslie Targownik, argue that the link might be overstated. People on long-term PPIs often have other health problems-smoking, poor nutrition, kidney disease, or immobility-that also harm bones. Maybe it’s not the drug-it’s the patient’s overall health. That’s a fair point. But even when studies adjust for those factors, the risk still shows up.
The American Gastroenterological Association says the benefits of PPIs usually outweigh the risks-if they’re used correctly. That’s the key: correctly. Most PPI prescriptions are unnecessary. One study found that 60-70% of long-term users didn’t have a clear medical reason to be on them. If you’re taking PPIs because you had heartburn once and never stopped, you’re probably at risk for nothing but side effects.
What You Can Do-Practical Steps
If you’re on PPIs, here’s what to do next:
- Ask your doctor if you still need it. Many people stay on PPIs for years after their original problem is gone. Try to taper off under supervision. Some people can switch to on-demand use-only taking it when symptoms flare.
- If you must stay on it, use the lowest dose possible. A 20mg dose of omeprazole is often enough. Higher doses don’t help more-they just increase risk.
- Switch to calcium citrate. If you’re taking calcium supplements, choose calcium citrate. It doesn’t need stomach acid to absorb. Calcium carbonate is cheaper, but useless if your acid is suppressed.
- Get enough vitamin D. Aim for 800-1000 IU daily. It helps your body use calcium. Many people are deficient, especially in winter.
- Get a bone density test if you’re at risk. If you’re over 65, female, underweight, or have other risk factors, ask your doctor about a DEXA scan. It’s quick, painless, and tells you if your bones are thinning.
- Move your body. Weight-bearing exercise-walking, lifting weights, yoga-strengthens bones. No pill replaces it.
Don’t stop your PPI cold turkey. Sudden withdrawal can cause rebound acid reflux. Work with your doctor to reduce slowly.
The Bigger Picture: Why So Many People Are on PPIs Long-Term
It’s not just doctors. Patients ask for them. Online ads push them. Pharmacies sell them over the counter. And they work-fast. But the problem is, most people don’t realize they’re treating a symptom, not a cure. Heartburn isn’t always GERD. Sometimes it’s diet, stress, or obesity. Changing your lifestyle can be more effective than any pill.
Between 2015 and 2021, long-term PPI prescriptions in Medicare patients dropped by nearly 20%. That’s progress. But nearly half of all prescriptions are still inappropriate. That means millions are taking a drug with known risks, without clear benefit.
The bottom line: PPIs are powerful tools. But like all powerful tools, they’re dangerous when misused. If you’ve been on them for years, it’s time to have a real conversation with your doctor-not just about your stomach, but about your bones.
Do proton pump inhibitors cause osteoporosis?
PPIs don’t directly cause osteoporosis, but long-term use is linked to a higher risk of bone loss and fractures, especially in older adults and those with other risk factors. The mechanism involves reduced calcium absorption due to lower stomach acid, and possibly direct effects on bone cells. It’s a modest increase in risk-not a guarantee-but it’s real enough to warrant caution.
How long do you have to take PPIs before fracture risk increases?
Risk starts to rise after about one year of daily use, but it becomes more significant after three to five years. The highest risk is seen in people taking high doses for seven or more years. Some studies show a nearly fivefold increase in hip fracture risk after seven years of continuous use.
Is calcium citrate better than calcium carbonate if I’m on PPIs?
Yes. Calcium carbonate needs stomach acid to be absorbed, which PPIs reduce. Calcium citrate doesn’t require acid-it’s absorbed just as well whether your stomach is acidic or not. If you’re on long-term PPI therapy, calcium citrate is the preferred supplement.
Should I stop taking PPIs because of bone risk?
Don’t stop abruptly. If you’ve been on PPIs for years without a clear medical reason, talk to your doctor about tapering off. If you have a serious condition like Barrett’s esophagus or recurrent ulcers, the benefits of PPIs likely outweigh the risks. The goal isn’t to avoid PPIs entirely-it’s to use them only when necessary and at the lowest effective dose.
Are there alternatives to PPIs for acid reflux?
Yes. H2 blockers like famotidine or ranitidine are less potent but carry lower fracture risk. Lifestyle changes-losing weight, avoiding late meals, cutting out caffeine and alcohol-can be very effective. For mild cases, elevating the head of your bed and chewing gum after meals can reduce reflux. In some cases, surgery like fundoplication is an option for long-term relief without drugs.
Final Thoughts: Balance, Not Fear
PPIs saved lives. They healed ulcers that once meant hospitalization. They turned chronic heartburn from a daily nightmare into a manageable condition. But medicine isn’t about taking pills forever-it’s about using the right tool for the right time.
If you’re on PPIs, don’t panic. Do check in. Ask your doctor: "Is this still necessary?" "Could I try a lower dose?" "Should I get my bone density checked?"
Your bones don’t shout before they break. They whisper. And if you’ve been on PPIs for years, it’s time to listen.
