Our bones really are the foundation of our bodies. They hold us up, protect our organs, and help us move. But just like muscles, bones can get weaker over time, leading to Osteoporosis. That’s why it’s important to know about bone density and a special test called a DEXA scan.
Let’s dive into what these mean and how they can help keep you healthy.
What Is Bone Density?
Think of your bones like a sponge. Some sponges are thick and strong, while others are thin and fragile. Bone density is a measure of how thick and strong your bones are. When you’re younger, your bones are usually strong and packed with minerals like calcium. But as you get older, bones can lose some of that strength. This makes them more likely to break. Low bone density is linked to a condition called osteoporosis, which simply means bones are weak and break more easily. The tricky part? You usually can’t feel your bones getting weaker. That’s why testing is so important.
What Is a DEXA Scan?
A DEXA scan (Dual-Energy X-ray Absorptiometry) is a safe, quick, and painless test that measures bone density. This machine gently scans your body using very low levels of X-rays, typically focusing on your lower spine and hips—areas where fractures are more serious. These tests only take about 10 minutes to complete and can give your care team all kinds of information about your bone health.
You might not notice that your bones are getting weaker, but the truth is, bone loss often happens quietly, without symptoms. Many people don’t know their bones are weak until they break a bone from something small—like tripping on a rug. A DEXA scan can tell you your bone strength before a fracture happens. It’s like getting a sneak peek into your bone health. This way, you and your doctor can make a plan to protect your bones.
Who Should Get a DEXA Scan?
Doctors often recommend bone density testing for:
-
Women over 65 and men over 70
-
Adults who have broken a bone after age 50
-
People with certain health conditions, like arthritis or thyroid disease
-
Those who take medicines that may weaken bones, such as steroids
-
People with family history of osteoporosis
Even if you’re younger, your doctor might suggest a scan if you have risk factors.
How Can a DEXA Scan Help You?
A DEXA scan gives you a score that shows how strong your bones are. Your doctor can use this score to:
-
Spot early bone loss – Catching weak bones early means you can take action.
-
Prevent fractures – With the right treatment, you may avoid painful and dangerous breaks.
-
Track progress – If you’re already on medicine or making lifestyle changes, scans can show if it’s working.
If your DEXA scan shows weak bones, don’t worry—there are many ways to help strengthen them. Even if your bones are healthy now, these steps can keep them that way:
-
Eat calcium-rich foods like milk, yogurt, cheese, and leafy greens.
-
Get vitamin D, which helps your body absorb calcium. Sunlight, fish, and fortified foods are good sources.
-
Exercise regularly, especially weight-bearing activities like walking, jogging, or dancing.
-
Avoid smoking and limit alcohol, since both can weaken bones.
-
Take medicine if needed, as prescribed by your doctor.
The Bottom Line
Your bones may be out of sight, but they should never be out of mind. A DEXA scan is a simple, safe, and powerful tool to check on your bone health. Knowing your bone density can help prevent serious problems down the road, like painful fractures. Think of it this way: you wouldn’t wait until your car engine breaks down to check the oil. In the same way, checking your bone density before problems start can keep you moving strong for years to come.
