When Is the Right Time to Get a DEXA Scan?

When we think of bones, we often imagine them as hard, unchanging structures that simply hold our body together. But in reality, our bones are living, dynamic tissues that constantly change throughout our lives. They grow, repair themselves, and unfortunately, can also weaken over time.
One of the best ways to check the health of your bones is through a DEXA scan (Dual-Energy X-ray Absorptiometry). But here’s the big question: When is the right time to get one?
Many people wait until they have a fracture or start experiencing symptoms of bone weakness before even thinking about it. But experts including Dr. Shreya Sharma, the best endocrinologist in Dehradun say that knowing when to get a DEXA scan can help you catch bone loss early and take action before it turns serious.

What is a DEXA Scan?

A DEXA scan is a simple, painless, and quick test that measures your bone mineral density (BMD). Think of it as a “bone strength test.”

    Here’s how it works:
  • You lie down on a table.
  • A special scanning machine passes low-dose X-rays over your body.
  • It measures how much calcium and other minerals are in your bones.
  • The results come in the form of T-scores and Z-scores:
  • T-score compares your bone density to a healthy young adult of the same sex.
  • Z-score compares your bone density to people of your own age, sex, and size.

If your T-score is -1 or above, your bone density is normal.
If it’s between -1 and -2.5, it indicates osteopenia (early bone loss).
Below -2.5, it means osteoporosis — a condition where bones become fragile and more likely to break.

Why Bone Health Matters More Than You Think?

We usually take our bones for granted — until something goes wrong. Bones not only give us shape and strength but also protect vital organs, store minerals like calcium, and work with muscles to help us move.
However, bone loss often happens silently. You may not feel pain or discomfort until a fracture occurs. That’s why early detection through a DEXA scan is so valuable.
According to Dr. Shreya Sharma, being the best Hormone doctor in Dehradun, she sees many patients who could have prevented fractures if they had checked their bone health earlier.

When Should You Get a DEXA Scan?

    There’s no “one-size-fits-all” answer, but here are some general guidelines recommended by bone health experts and endocrinologists.
  • Women Aged 65 and Above:
    Women lose bone mass faster after menopause due to a sharp drop in estrogen levels. Most medical guidelines recommend all women aged 65+ get a DEXA scan — even if they feel healthy.
  • Men Aged 70 and Above:
    Men generally have stronger bones than women, but age-related bone loss still happens. Men aged 70+ should get their bone density checked at least once.
  • Women Under 65 With Risk Factors:
    If you’re younger than 65 but have risk factors (we’ll list them below), you should get tested earlier.
  • Men Aged 50–69 With Risk Factors:
    Similarly, men in this age group with certain health or lifestyle risks should also be tested sooner.
  • Anyone Who Has a Fracture After Age 50:
    Breaking a bone from a simple fall after age 50 can be a red flag for weak bones. A DEXA scan can confirm if osteoporosis is the cause.
  • People With Certain Medical Conditions:
    Certain health issues can speed up bone loss, including:
    Rheumatoid arthritis
    1. Thyroid disorders
    2. Hormonal imbalances
    3. Chronic kidney disease
    4. Gastrointestinal disorders (like celiac disease)
    This is where Endocrinology consultation in Dehradun can help you — an expert can assess whether your condition requires early testing.
  • Early Menopause or Low Testosterone:
    Women who go through menopause before age 45 and men with low testosterone should consider early screening.
  • People With Family History of Osteoporosis:
    If your parents had hip fractures or osteoporosis, your risk increases — and so should your awareness.

Risk Factors That Should Put You on Alert:

Bone loss risk increases with age, but there are other factors to watch for:

  • Family history of osteoporosis
  • Low body weight
  • Smoking
  • Excessive alcohol use
  • Lack of physical activity
  • Poor calcium and vitamin D intake
  • Certain medications
  • Hormonal disorder
  • If you relate to any of these, it’s worth talking to Dr. Shreya Sharma for guidance on whether you need a scan.

Myths About DEXA Scans:

Myth 1: Only old people need a DEXA scan.
Fact: Bone loss can begin much earlier, especially with poor lifestyle habits or medical conditions.

Myth 2: It’s painful and dangerous.
Fact: The scan is painless and uses a very low level of radiation — less than a chest X-ray.

Myth 3: You only need it once.
Fact: Bone health changes over time. You may need follow-up scans every 1–2 years if you’re at risk.

Myth 4: If you feel fine, your bones are fine.
Fact: Osteoporosis is called the “silent disease” because it shows no symptoms until a fracture occurs.

How Often Should You Repeat a DEXA Scan?

If your bone density is normal, you may not need another scan for 5–10 years. If you have osteopenia or osteoporosis, your doctor may recommend repeating it every 1–2 years to monitor changes and treatment effectiveness.

Preparing for Your DEXA Scan:

It’s easy — no fasting or special prep needed. Just:

  • Avoid taking calcium supplements for 24 hours before the test
  • Wear comfortable clothing without zippers or metal buttons

What Happens After the Test?

Your doctor will explain your results and recommend steps if needed. This could include:

  • Diet changes
  • Exercise plans
  • Supplements
  • Medication to strength bones
  • If you’re in Uttarakhand, getting an Endocrinology consultation in Dehradun with Dr. Shreya Sharma can help you get a personalized plan.

How to Keep Your Bones Strong – Even Before a DEXA Scan?

    Whether you’ve had a scan or not, these habits help protect your bones:
  • Eat calcium-rich foods like dairy, green leafy vegetables, and fortified foods.
  • Get enough vitamin D through sunlight and diet.
  • Exercise regularly, focusing on weight-bearing activities like walking, dancing, or light jogging.
  • Avoid smoking and limit alcohol.
  • Maintain a healthy weight — too low or too high can be harmful to bones.

The Role of an Endocrinologist in Bone Health:

An endocrinologist is a hormone specialist, and hormones play a huge role in bone health.

  • If there’s a hormonal imbalance, it can speed up bone loss.
  • Estrogen, testosterone, thyroid hormones, and cortisol all influence bone density.

That’s why consulting the best Hormone doctor in Dehradun Dr. Shreya Sharma can make all the difference. She not only checks your bone density but also investigates underlying hormonal causes and gives you a tailored treatment plan.
Your bones are your lifelong support system. The earlier you detect bone loss, the easier it is to prevent fractures and maintain mobility.
If you’re at risk — whether due to age, family history, medical conditions, or lifestyle — don’t delay. Book a DEXA scan and get an Endocrinology consultation in Dehradun with Dr. Shreya Sharma, the best endocrinologist in Dehradun.
Remember: prevention is always better than cure — and in the case of bone health, it can also mean avoiding years of pain, disability, and loss of independence.
