Why is Preparation Important?
Proper preparation is crucial to ensure accurate and reliable results from your DEXA scan. Failing to prepare adequately can lead to inaccurate readings, which may hinder your ability to make informed decisions about your fitness and nutrition plan. By following the guidelines outlined in this article, you'll be able to get the most out of your DEXA scan and gain a deeper understanding of your body.
What to Expect During the Scan
The DEXA scan process is quick, easy, and painless. You'll lie down on a comfortable examination table, and the scanner will pass over your body, emitting low-level X-rays. The entire process typically takes around 10-15 minutes, depending on the type of scan and the specific areas being measured. During the scan, you'll be asked to remain still and hold your breath for a few seconds to ensure accurate readings.
Pre-Scan Preparation: Clothing and Accessories
To ensure accurate results, it's essential to wear clothing and accessories that won't interfere with the scan. Please avoid wearing:
- Metallic objects, such as jewelry, glasses, or clothing with metal fasteners
- Clothing with high-density materials, like lead or copper
- Anything with metal threads or wire, including underwire bras
- Shoes or clothing with metal buckles or zippers
Instead, opt for comfortable, loose-fitting clothing made from natural fibers like cotton or linen. Remove any jewelry, glasses, or metal objects before the scan, and avoid wearing anything that may contain metal or high-density materials.
Dietary Preparations
Your diet can impact the accuracy of your DEXA scan results. To ensure the most accurate readings, follow these dietary guidelines:
- Avoid consuming calcium supplements or calcium-rich foods for at least 24 hours before the scan
- Limit your intake of foods high in fiber, such as beans, broccoli, or cabbage, for 24 hours prior to the scan
- Refrain from eating or drinking anything for at least 2 hours before the scan, except for water
Additionally, try to maintain a consistent diet and hydration level in the days leading up to your scan. This will help ensure that your body composition and bone density readings are accurate and representative of your typical state.
Hydration and Medications
Proper hydration is essential for accurate DEXA scan results. Make sure to drink plenty of water in the days leading up to your scan, and avoid excessive caffeine or diuretics, which can affect your hydration levels.
If you're taking any medications, inform your healthcare provider or the DEXA scan technician. Certain medications, such as osteoporosis treatments or hormone replacement therapy, may affect your bone density readings.
Physical Activity and Sleep
Try to maintain your regular physical activity routine in the days leading up to your DEXA scan. Avoid any strenuous exercise or activities that may cause muscle soreness or inflammation, as this can affect your body composition readings.
Aim to get a good night's sleep before your scan, as fatigue can impact your body's hydration levels and overall physiology. Aim for 7-9 hours of sleep to ensure you're well-rested and ready for your scan.
What to Expect After the Scan
After your DEXA scan, you'll receive a comprehensive report outlining your body composition, bone density, and fat mass. Our team of experts will review the results with you, providing personalized recommendations and guidance to help you achieve your fitness goals.
Use your DEXA scan results as a baseline to track your progress over time. By making adjustments to your diet, exercise routine, and lifestyle, you can optimize your body composition, improve your overall health, and achieve the physique you desire.

Frequently Asked Questions
What is a DEXA scan?
A DEXA (Dual-Energy X-ray Absorptiometry) scan is a non-invasive medical test that measures bone density and body composition, including fat mass and lean mass. It's commonly used to diagnose osteoporosis, monitor bone loss, and track changes in body composition over time.
Why do I need a DEXA scan?
You may need a DEXA scan if you're at risk for osteoporosis, have a family history of the condition, or are experiencing symptoms such as back pain or height loss. Additionally, athletes and individuals who want to monitor their body composition for performance or aesthetic purposes may also benefit from a DEXA scan.
How does a DEXA scan work?

What happens after the scan?
After the scan, a healthcare professional will analyze the results and provide you with a detailed report, which may include recommendations for improving your bone density or body composition.
How often should I get a DEXA scan?
The frequency of DEXA scans depends on your individual needs and health status. Typically, scans are recommended every 1-2 years for individuals at risk of osteoporosis, and every 6-12 months for athletes or individuals monitoring their body composition.
What does the scan measure?
A DEXA scan measures bone density, fat mass, lean mass, and percentage body fat. It also provides information on visceral fat, which is fat that accumulates around the organs in the abdominal cavity.
What is the difference between bone density and bone mass?
Bone density refers to the amount of mineral content in your bones, while bone mass refers to the overall amount of bone tissue. A DEXA scan measures both bone density and bone mass.
What is T-score and Z-score?
The T-score compares your bone density to that of a healthy 30-year-old adult, while the Z-score compares your bone density to that of others of the same age, sex, and ethnicity. These scores help healthcare professionals diagnose and monitor osteoporosis.
What is body composition analysis?
Body composition analysis is the measurement of the percentage of fat and lean mass in your body. This information can help you track changes in your physique, monitor progress towards fitness goals, and identify potential health risks.
How accurate is a DEXA scan?
DEXA scans are highly accurate, with a precision error of around 1-2%. However, results may vary depending on the individual's hydration level, body position, and other factors.
Can I get a DEXA scan if I'm pregnant or breastfeeding?
It's generally not recommended to get a DEXA scan during pregnancy or breastfeeding, as the radiation exposure, although low, may pose a risk to the fetus or baby. However, your healthcare provider may recommend a scan in certain circumstances.
Can children get a DEXA scan?
Yes, children can get a DEXA scan, although the procedure and results may vary depending on their age and developmental stage.
How much does a DEXA scan cost?
The cost of a DEXA scan varies depending on the location, provider, and individual's insurance coverage. On average, the cost ranges from $100 to $300.
Is a DEXA scan covered by insurance?
Insurance coverage for DEXA scans varies depending on the individual's policy and provider. Some insurance plans may cover the scan as part of a routine health exam, while others may require a copayment or deductible.
What if I have a metal implant or pacemaker?
If you have a metal implant or pacemaker, inform your healthcare provider before the scan. In some cases, the scan may not be recommended or may require special precautions.
Can I get a DEXA scan if I'm claustrophobic?
If you're claustrophobic, inform your healthcare provider before the scan. In some cases, the scan may be adapted to accommodate your needs, or alternative procedures may be recommended.
