While shedding pounds improves many aspects of health, it can also reduce bone density, raising the risk of fractures. This is true whether weight loss comes from diet and exercise, prescription medications, or surgery.
Why Bone Loss Happens
During weight loss the body may break down bone faster than it builds new bone. Factors include lower mechanical loading on the skeleton and reduced intake of nutrients essential for bone health.
Medications and Bone Health
GLP‑1 drugs such as semaglutide (Wegovy) and tirzepatide (Zepbound) are effective for weight loss, but research shows people who lose more weight with these agents also tend to lose more bone. The bone loss appears comparable to that seen with non‑surgical weight loss, suggesting the weight reduction itself—not the medication—is the primary driver.
Steps to Safeguard Your Bones
Exercise regularly. Weight‑bearing activities (walking, jogging, dancing) signal the body to maintain bone strength. Experts recommend at least three strength‑training sessions per week combined with 150 minutes of aerobic exercise.
Get enough protein, calcium, and vitamin D. Cutting calories can make it harder to meet these nutrient needs. Work with your healthcare team to determine the right daily amounts for your age, sex, and health status.
Monitor bone health. A dual‑energy X‑ray absorptiometry (DEXA) scan measures bone density and can detect loss before a fracture occurs. Those at higher risk for osteopenia or osteoporosis may be advised to have a DEXA every one to two years, along with tracking muscle mass.
Consider treatment if needed. If osteoporosis develops, medication may be prescribed in addition to exercise and nutrition. Treatment decisions depend on bone density results, fracture risk, and overall health.
When to Seek Medical Advice
Contact your healthcare provider if you experience a fracture, have a condition or take drugs that weaken bone, or notice signs of bone loss. Your doctor can order a DEXA scan, run blood tests for nutrient levels, and create a personalized bone‑health plan.
Overall, protecting bone health should be an integral part of any weight‑loss strategy. By staying active, eating nutrient‑rich foods, and monitoring bone density, you can lose weight safely while keeping your skeleton strong.
