People living with HIV face a substantially elevated risk for osteoporosis and bone fractures compared to those without HIV, a consequence of how the virus directly affects bone cells, immune function, and how HIV medications work in the body. Understanding this connection is crucial because osteoporosis, known as the silent disease, often shows no symptoms until a fracture occurs. The good news: targeted prevention strategies and bone health screening can significantly reduce this risk. How Does HIV Directly Damage Bone? Your bones are constantly renewing themselves through a process called bone remodeling, where old bone is removed and replaced with new bone. This keeps your skeleton strong and prevents brittle bone buildup. With osteoporosis, this balance shifts dangerously—more bone is lost than replaced, making bones thinner, weaker, and prone to breaking. HIV disrupts this delicate balance in multiple ways. The virus can directly infect the cells responsible for removing old bone, and it also increases the activity of these bone-removing cells while signaling the body to produce more of them. This leads to accelerated bone loss. Even when HIV treatment successfully reduces the virus to undetectable levels, viral proteins remain in the body and continue to interfere with bone formation. "There are a number of ways that having HIV contributes to changes in the bone," explains Dr. Anjali Sharma, a professor and researcher with a focus on HIV in women at the Albert Einstein College of Medicine. Additionally, HIV disrupts the immune system in ways that don't fully resolve with treatment, creating chronic low-level inflammation that further damages bone-removing cells. What Role Do HIV Medications Play in Bone Loss? While antiretroviral therapy (ART) has been transformative for people with HIV, allowing them to live longer, healthier lives, these medications come with bone-related side effects. When someone starts ART for the first time, the immune system rapidly rebuilds itself to restore function. This process triggers increased inflammation throughout the body for approximately one year, during which bone loss accelerates as more bone is removed than formed. The impact varies by medication. Some HIV drugs cause more bone loss than others, but the good news is that switching to newer formulations with fewer bone-related side effects has been shown to improve bone density. This means discussing medication options with your healthcare provider is an important conversation for anyone with HIV concerned about bone health. What Other Factors Increase Bone Loss Risk in People With HIV? Beyond the virus and medications themselves, several other factors compound bone loss risk in people living with HIV. These include: - Medical Conditions: Chronic liver or kidney disease and early-onset menopause (before age 45) are more common in people with HIV and significantly increase osteoporosis risk - Lifestyle Factors: Smoking and alcohol use have been linked with osteoporosis and may be more prevalent in people with HIV - Age: Older age is a risk factor for everyone, but people with HIV may develop osteoporosis at younger ages than those without HIV, making age-related bone loss especially concerning Ways to Protect Your Bones When Living With HIV - Calcium Intake: Ensure you're getting adequate dietary calcium to keep bones strong. Older adults require higher amounts of dietary calcium because the body's ability to absorb it decreases with age - Vitamin D Supplementation: Vitamin D plays critical roles in bone health by helping the body absorb calcium from food, supporting skeletal renewal and mineralization, and keeping muscles strong to reduce fall risk. People with low vitamin D levels should take supplements alongside calcium to ensure adequate intake - Quit Smoking and Limit Alcohol: Both smoking and excessive alcohol use accelerate bone loss and harm overall health, making cessation and moderation essential for bone protection - Weight-Bearing Exercise: Regular weight-bearing exercises like running or dancing stress bones and muscles, causing them to strengthen in response. Exercise helps build and maintain bone and muscle strength while improving balance to prevent falls - Hormone Therapy: For women after menopause or transgender women, estrogen-based hormone therapy has been shown to improve bone mineral density - Fall Prevention: Since osteoporosis is more common in people with HIV, preventing falls becomes critical. Remove trip hazards at home, ensure good lighting, keep eyeglasses properly fitted, and wear comfortable flat shoes Who Should Get Bone Density Screening and When? Because people living with HIV face higher osteoporosis and fracture risk, specific screening recommendations exist. The standard screening tool is a dual energy X-ray absorptiometry (DEXA) scan, which measures bone mineral density and helps predict fracture risk. A DEXA scan is recommended for all women with HIV after menopause and for everyone with HIV starting at age 50. However, people with HIV who take certain medications like steroids, have a history of fracture, or have conditions putting them at high risk for osteoporosis should have screening at an earlier age. Discussing your individual risk factors and screening timeline with your healthcare provider ensures you catch bone loss before it becomes dangerous. The key takeaway: living with HIV means taking bone health seriously, but with proper screening, medication management, and lifestyle strategies focused on calcium, vitamin D, exercise, and fall prevention, you can significantly reduce your fracture risk and maintain strong bones throughout your life.
