Ozempic Bone Loss: What Women Over 40 Should Know

The prospect of Ozempic bone loss sounds scary, but if you’ve been considering or are taking semaglutide, don’t let that concern on its own knock you off-kilter. Bone loss is an understandable concern for women in perimenopause and menopause, since it naturally speeds up during this stage of life. 

But so far, research on semaglutide suggests that it’s more likely weight loss—not semaglutide itself—that may lower bone mineral density. And the impact may be modest. So, while bone loss is important to keep in mind when you’re taking a medication that produces weight loss, the risk can be manageable with the right information, tools, and lifestyle changes. 

Let’s look at what the research shows when it comes to GLP-1 bone density, how it affects women in midlife, and who’s most at risk. We’ll also go over the elements of a concrete plan to protect your bones while you’re taking a GLP-1.

And in case you missed it: Midi clinicians can help you figure out a weight management plan that keeps your whole health, including bone health, at the forefront, helping you reach your goal in a safe and sustainable way.

Does Ozempic Cause Bone Loss? What the Research Says

The question “Does semaglutide cause bone loss?” is still being studied, but so far, it seems that the weight loss that results from taking the medication is mainly responsible for bone density changes, rather than the medication itself. (Semaglutide medications include GLP-1 agonists Ozempic, which is approved to treat type 2 diabetes, and Wegovy, which is approved to treat obesity, among other conditions. Studies have focused on different doses and forms.) 

In one small 2024 study, adults at increased fracture risk who took semaglutide for a year had lower bone mineral density at the hip and lumbar spine than those taking a placebo. But they also lost significantly more weight than the placebo group, and the researchers suggested that the increased bone loss among those taking semaglutide may have been due to the weight loss.

Meanwhile, a retrospective study from 2026 showed that people taking semaglutide (or tirzepatide, another weight loss medication) lost slightly more hip bone density than people who weren’t taking the drug—an amount that was only marginally statistically significant. 

But a different 2024 study provides an encouraging clue about how to protect your bones while losing weight: Researchers studying liraglutide (another GLP-1 medication) found that people who combined the medication with supervised exercise didn’t lose bone density, despite their weight loss. Those who took liraglutide without exercise, on the other hand, experienced modest decreases in bone density at the hip and spine.

Why Significant Weight Loss Affects Bone Density

When you lose a lot of weight, your body responds—and that includes your skeleton. Bones respond to mechanical load, so when there’s less weight to carry, there’s also less of a signal to build new bone and maintain it. 

This impact is crucial to understanding the connection between semaglutide medications like Wegovy or Ozempic and bone density. Reassuringly, a 2015 meta-analysis of weight loss studies (in this case, weight loss from dieting, not from medications) found that while hip bone density decreased slightly, the change was small and did not outweigh the significant overall health benefits of weight loss. It’s still important, though, to be aware of this effect.

Another factor in your skeleton’s health: You often lose lean muscle mass when you lose weight, and this affects your bones in several ways. Having less muscle mass means less density-building load on your bones, and weaker muscles put you at higher risk of falls. Reduced appetite from GLP-1 medications may play an indirect role, too: When you’re eating less, you may not get enough protein, calcium, and vitamin D—all of which your bones need to stay strong.

This impact isn’t just seen with GLP-1s. People who undergo bariatric surgery or lose substantial weight through intense dieting can also experience a lessening of bone density.

Why This Matters More for Women in Perimenopause and Menopause

Bone loss is a particular concern for women in perimenopause and menopause. Estrogen plays a protective role in bone health, and when it declines during the menopause transition, two things happen: The loss of bone increases, and the formation of new bone is inhibited. The result is lower bone density. 

When you consider that midlife women make up a significant group of people taking GLP-1s, it’s clear that bone health deserves particular attention alongside other menopause changes, including muscle loss, sleep disruption, and changing body composition. 

Can Ozempic Cause Osteoporosis? Who Is Most at Risk

If you’re wondering, “Does Ozempic cause osteoporosis?,” you’re not alone. So far, the research points to “No, it doesn’t”—instead, the weight loss itself is what potentially leads to a loss of bone density, which is the main characteristic of osteoporosis.

Some bone-health definitions to know:

• Osteopenia: bone density that is lower than normal 
• Osteoporosis: bone density that’s so low that bones become fragile and your risk of fracture is increased 

Bone density is assessed via a test called a DEXA scan, which uses low-dose X-rays to measure how much calcium and other minerals are present. 

Some factors that could raise your risk for osteopenia and osteoporosis, besides low bone density, include:

• being postmenopausal 
• having a low body weight (less than 127 pounds) or losing a lot of weight  
• having a family history of osteoporosis 
• smoking
• having poor nutrition, vitamin D deficiency, or an eating disorder 
• using steroids long term 
• heavily consuming alcohol (more than 2 drinks daily)
• hyperthyroidism (overactive thyroid—having low TSH)

Signs Your Bones May Need Attention on a GLP-1

Bone loss is often silent, so the first sign is often a fracture—which is why risk assessment is so important before that happens. If you have risk factors of osteoporosis, ask your clinician whether you should consider bone-density testing before or during GLP-1 treatment.

Even though osteoporosis typically doesn’t have obvious symptoms, there are some warning signs of possible bone loss that you should bring to your clinician’s attention:

• A fracture resulting from a minor fall: This can be a sign that your bones are compromised or weakened.
• Loss of height: A new stoop or shrinkage can be evidence of bone loss.
• New back pain: Unexplained pain in this area can have many causes, but it can also be a sign of a vertebral fracture.
• Noticeable muscle and strength loss: Losing muscle along with weight can be a concern for bone health, while persistent or unexplained pain deserves evaluation.

And when your weight loss is significant and you have other risk factors for osteoporosis, you and your clinician should keep a focus on protecting your bones.

How to Protect Your Bones While Taking Ozempic or Wegovy

If you’re concerned about the relationship between Ozempic or Wegovy and bone density, you can take several steps to protect yourself:

• Prioritize protein: Getting enough protein is essential for preserving muscle and bone during weight loss. During active weight loss, experts suggest aiming for about 1.2 to 1.6 grams (g) of protein per kilogram of body weight per day. (Midi clinicians generally recommend 1.6 g while on a GLP-1 medication). If your appetite is low, try eating the protein-heavy part of your meal first to make sure to get it in.
• Make strength training a habit: Strength training and weight-bearing exercise can help preserve your bones during weight loss. In research, people who combined exercise with a GLP-1 maintained bone density, despite greater weight loss. If you’re new to strength training, start with manageable resistance or weights, and gradually increase the load as you get stronger. 
• Get enough calcium and vitamin D: These nutrients are essential for bone health. Food sources are best, so reach for options like dairy products, fortified plant milks, tofu, and canned salmon or sardines with bones. If you’re not getting enough through food, speak with your clinician about adding a supplement. Midi clinicians generally recommend that women get 1,000 to 1,200 milligrams (mg) of calcium per day and 1,000 to 2,000 mg of vitamin D per day via food and, if needed, supplements (such as Midi’s GLP-1 Support, which helps replenish nutrients for women on GLP-1s). 

Where Hormone Therapy and DEXA Monitoring Fit In

Hormone replacement therapy (HRT, now commonly referred to as menopause hormone therapy, or MHT) can be an option for preventing bone loss in some women. In fact, for many women, it may complement a GLP-1.

Whether HRT is right for you depends on many factors, including your age, time since menopause, symptoms you’re experiencing, and personal and family health history. A menopause-informed clinician, like one at Midi, can help you decide whether it’s a good option for you.

DEXA monitoring may be appropriate for some women as well. Your clinician may recommend a DEXA scan based on your age and risk factors, and they can tailor your health plan according to the results. If more monitoring is needed, your clinician can determine when you should be tested again.

Midi clinicians specialize in integrating GLP-1 therapy with comprehensive menopause care, evaluating every facet of your health. Rather than treating bone health as an afterthought, clinicians incorporate proactive bone protection directly into your personalized Care Plan.

Should You Stop Ozempic to Protect Your Bones?

Concerns about bone loss don’t necessarily mean you need to stop using a GLP-1. Semaglutide medications are prescribed for various health benefits, including blood sugar control, reducing heart risks, and lowering the risk of kidney disease. If you stop suddenly or without a clinician’s guidance, those benefits could be reversed. 

Instead, depending on your individual risk factors, your clinician could adjust your treatment plan or suggest specific steps you can take to help protect your bones.

Remember, any changes to your prescription should be made with your clinician. Never just stop the medication on your own without having that important conversation. The solution to your concerns may be easier or more accessible than you think. 

When to Talk With a Clinician About Bone Health on a GLP-1

You want to keep your skeleton as strong as possible, and it makes sense to be proactive about it. In particular, you should bring up the topic with your clinician before you start a GLP-1 if you’re postmenopausal or have other risk factors. And if you fracture a bone, you notice a change in your height, or a DEXA scan shows you have osteopenia, then it’s definitely time for a bone health chat. 

A clinician can assess your fracture risk, order DEXA or vitamin D testing, and tailor your protein and exercise goals specifically to your bone health needs. They can also explore options like HRT or targeted bone medications, when appropriate. Through Midi, you can easily connect with clinicians who specialize in menopause care and GLP-1 weight management, with services that are in network with most major insurance providers.

Bone health is an important part of your overall wellness picture in midlife—the goal is to keep those bones strong, so you can move through your life as active and vibrant as possible. 

Key Takeaways

• GLP-1 medications like Ozempic and Wegovy may affect bone density, but research suggests that weight loss itself, rather than GLP-1 medication alone, may be the cause. And research has shown that bone loss is modest.
• Women in perimenopause and menopause may need to pay particular attention to bone health because declining estrogen already accelerates bone loss during this stage of life.
• Significant weight loss can affect bone through several pathways, including loss of muscle mass and reduced mechanical load on the skeleton. 
• Getting enough protein, calcium, and vitamin D can help protect muscle and bone while you’re taking a GLP-1. Another key factor is doing regular resistance and weight-bearing exercise.
• Concerns about bone loss don’t necessarily mean you need to stop GLP-1 medications. Your clinician can assess your risk, determine whether bone-density testing is appropriate, and help you build bone protection into your treatment plan.

Frequently Asked Questions (FAQs)

Can bone loss from Ozempic be reversed?

Bone density that’s decreased when you’re losing weight may be recoverable to some degree, depending on factors such as your age, menopause status, and overall bone health. Doing resistance and weight-bearing exercise; consuming adequate protein, calcium, and vitamin D; and getting treatment for osteoporosis when appropriate can all help protect and strengthen bones.

Can you rebuild bone density?

Yes, bone is living tissue that is constantly being broken down and rebuilt. How much density can be regained depends on your individual health and the degree of bone loss. Resistance and weight-bearing exercise, adequate nutrition, and medications or hormone therapy when appropriate can help maintain or improve bone density. 

Which vitamin is best for osteopenia?

Vitamin D is particularly important because it helps your body absorb calcium, which is essential for building and maintaining bone. But vitamin D isn’t a stand-alone treatment for osteopenia. Adequate calcium and protein, regular weight-bearing and resistance exercise, and other treatment when indicated are also important for bone health.

Does Ozempic cause bone pain?

Bone pain is not generally considered a typical side effect of Ozempic. Talk with your clinician about new or persistent pain, particularly if you have risk factors of osteoporosis. Unexplained back pain, for example, can have many causes but can sometimes be a sign of a vertebral fracture, so it should be evaluated.

What organ is Ozempic hard on?

Ozempic isn’t generally described as being “hard on” one particular organ. However, semaglutide carries warnings and precautions for certain people involving the pancreas, gallbladder, and kidneys, among others. Talk with your clinician about your individual risks and reach out if you have any concerning symptoms while taking the medication.
