Menopause and Bone Health: When to Get a DEXA Scan

Menopause marks a turning point for bone health. In the years immediately following menopause, women can lose up to 20 percent of their bone density. This rapid bone loss dramatically increases the risk of osteoporosis and fractures — but a DEXA scan can detect the problem early, when treatment is most effective.

Why Menopause Accelerates Bone Loss

Estrogen plays a critical role in maintaining bone strength. It helps regulate the balance between bone-building cells (osteoblasts) and bone-removing cells (osteoclasts). When estrogen levels drop during menopause, this balance shifts, and bone is broken down faster than it is rebuilt.

According to the National Osteoporosis Foundation, the average woman loses 10 percent of her bone mass in the first five years after menopause. For some women, the loss is even greater.

This bone loss is silent — you cannot feel it happening. The first sign is often a fracture, which is why screening with DEXA is so important.

When Should You Get a DEXA Scan

The U.S. Preventive Services Task Force recommends DEXA screening for all women age 65 and older. However, if you have risk factors for osteoporosis, you may need screening earlier — sometimes right at the time of menopause.

Consider a DEXA scan before age 65 if you have:

• Early menopause (before age 45)
• A family history of osteoporosis or hip fracture
• Low body weight (under 127 pounds)
• A history of smoking
• Excessive alcohol use
• Long-term use of corticosteroids (prednisone, etc.)
• A history of fracture as an adult
• Rheumatoid arthritis or other inflammatory conditions

Your doctor can use a risk assessment tool called FRAX to estimate your 10-year fracture probability and determine when to start screening.

What DEXA Measures

A DEXA scan measures bone mineral density (BMD) at your hip and spine — the two areas most vulnerable to osteoporotic fractures. The results are reported as a T-score, which compares your bone density to that of a healthy 30-year-old.

• T-score of -1.0 or higher — Normal bone density
• T-score between -1.0 and -2.5 — Osteopenia (low bone density)
• T-score of -2.5 or lower — Osteoporosis

If you have osteopenia, lifestyle changes and possibly medication can prevent further bone loss. If you have osteoporosis, treatment is essential to reduce your fracture risk.

What You Can Do to Protect Your Bones

Whether your DEXA results are normal or concerning, there are steps every woman can take to maintain bone health through menopause and beyond:

Calcium and vitamin D — The National Institutes of Health recommends 1,200 mg of calcium and 600 to 800 IU of vitamin D daily for women over 50.

Weight-bearing exercise — Walking, jogging, dancing, and strength training stimulate bone formation.

Avoid smoking and limit alcohol — Both accelerate bone loss.

Fall prevention — Remove tripping hazards at home, check your vision, and review medications that cause dizziness.

Medications — If you have osteoporosis, your doctor may prescribe bisphosphonates or other medications that slow bone breakdown.

How Often Should You Repeat a DEXA

If your initial DEXA shows normal bone density, your doctor will likely recommend repeating the scan every two to three years. If you have osteopenia or osteoporosis, more frequent monitoring (every one to two years) may be appropriate to track treatment effectiveness.
