Wondering whether you need a bone density scan before 65? Learn who may benefit from earlier osteoporosis screening, important risk factors, and what a DXA scan can tell you about bone health.
Many people assume that a bone density scan is something you only need after turning 65. While age is an important factor in osteoporosis screening, some people may need a bone density test earlier because of their individual risk factors.
A bone density scan, commonly called a DXA or DEXA scan, measures bone mineral density and can help healthcare professionals assess the risk of osteoporosis and fractures.
What Is a Bone Density Scan?
A bone density scan is a quick, noninvasive test that commonly measures bone density at the hip and spine.
The test can help identify:
- Low bone density
- Osteoporosis
- Increased fracture risk
- Changes in bone health over time
It is different from a regular X-ray because it is specifically designed to measure bone mineral density.
Do You Automatically Need One Before 65?
Not necessarily.
For many women, routine osteoporosis screening is recommended beginning at age 65. However, younger postmenopausal women may be candidates for screening when they have risk factors that increase their likelihood of osteoporosis or fractures.
For men, screening recommendations can differ, so discussing individual risk with a healthcare professional is important.
Who May Need a Scan Earlier?
A doctor may consider earlier bone-density testing if you have certain risk factors.
1. A Previous Fracture
A fracture that occurred from a relatively minor fall or accident can sometimes be a warning sign of reduced bone strength.
If you’ve experienced a fracture from an event that would not normally be expected to break a healthy bone, discuss it with your doctor.
2. Low Body Weight
Being significantly underweight can be associated with a higher risk of osteoporosis.
Your healthcare professional can consider your weight along with your age, medical history, medications, and other risk factors.
3. Family History of Osteoporosis or Hip Fracture
Genetics can influence bone health.
A family history of osteoporosis or a hip fracture, particularly in a parent, may increase your risk and may influence whether earlier assessment is appropriate.
4. Certain Medications
Long-term use of some medications can affect bone health.
For example, prolonged treatment with glucocorticoid or steroid medications can increase the risk of bone loss.
If you’re taking these medicines regularly, ask your healthcare professional whether bone-density monitoring is appropriate.
5. Certain Medical Conditions
Some medical conditions can increase the risk of osteoporosis or interfere with normal bone metabolism.
Examples can include certain hormonal disorders, gastrointestinal conditions that affect nutrient absorption, kidney disease, and other chronic conditions.
The decision to screen should be based on your overall medical situation rather than one condition alone.
Menopause Can Also Matter
Bone loss can accelerate around menopause because estrogen levels decline.
For this reason, a woman younger than 65 who has already gone through menopause and has additional osteoporosis risk factors may benefit from discussing earlier screening with her healthcare professional.
Premature or early menopause can also be an important factor to mention to your doctor.
What Happens During a DXA Scan?
A DXA scan is generally quick and painless.
You typically lie on a scanning table while the machine measures bone density, commonly at the hip and lower spine.
The test uses a very small amount of radiation and usually does not require injections or anesthesia.
Your healthcare professional will interpret the results in the context of your age, sex, medical history, and fracture risk.
Can You Improve Bone Health Without a Scan?
A bone-density scan can provide useful information, but healthy bone habits are important regardless.
Get Enough Calcium
Calcium is an important building block for bones.
Good food sources include:
- Milk
- Yogurt
- Cheese
- Fortified foods
- Some leafy green vegetables
- Tofu made with calcium
- Certain fish eaten with edible bones
Your individual calcium requirement depends on factors such as age and sex.
Don’t Forget Vitamin D
Vitamin D helps the body absorb calcium.
Your doctor can advise whether you need dietary changes, supplementation, or testing based on your individual circumstances.
Perform Weight-Bearing and Resistance Exercise
Walking, stair climbing, dancing, resistance exercises, and other weight-bearing activities can support bone and muscle health.
Strengthening the muscles around your hips and legs can also help support mobility and balance.
Avoid Smoking
Smoking is associated with poorer bone health and increased fracture risk.
If you smoke, quitting can benefit your bones as well as your overall health.
Limit Excessive Alcohol
Heavy alcohol consumption can negatively affect bone health and increase the risk of falls and fractures.
Keeping alcohol intake within recommended limits—or avoiding it altogether—is a healthier choice for bone protection.
A Bone Scan Is Not Only About Osteoporosis
One important reason to take bone health seriously is that osteoporosis can develop without obvious symptoms.
Many people don’t know they have significantly reduced bone density until they experience a fracture.
That’s why screening decisions are based on age plus individual risk factors, rather than symptoms alone.
When Should You Talk to Your Doctor?
Consider discussing a bone-density assessment if you are younger than the usual screening age but have risk factors such as a previous low-trauma fracture, low body weight, early menopause, prolonged steroid use, certain medical conditions, or a strong family history of osteoporosis.
Your doctor can determine whether a DXA scan is appropriate and how frequently it should be repeated.
The Bottom Line
You don’t necessarily have to wait until 65 to think about bone health.
For many people, routine screening begins at an older age, but certain risk factors can make earlier bone-density testing appropriate.
The best approach is to look at your complete health picture rather than relying on age alone. Regular exercise, adequate calcium and vitamin D, healthy lifestyle habits, and appropriate medical screening can all play a role in protecting your bones as you age.
