What to Do Before a DEXA Scan
DEXA scans, also known as dual-energy X-ray absorptiometry scans, are a valuable tool for measuring bone density and diagnosing osteoporosis. To ensure the accuracy and reliability of the results, it is essential to prepare properly before undergoing the procedure. Here’s a comprehensive guide on what to do before a DEXA scan.
1. Consult with Your Doctor
Before scheduling a DEXA scan, it is crucial to consult with your doctor. They can provide you with specific instructions based on your medical history and the purpose of the scan. Additionally, your doctor may need to adjust any medications you are currently taking or advise you on how to manage them during the preparation period.
2. Follow Dietary Guidelines
To obtain accurate results, it is important to follow dietary guidelines before your DEXA scan. Avoid consuming calcium-rich foods and supplements for at least 24 hours before the procedure, as they can interfere with the bone density measurements. Your doctor may also advise you to avoid high-protein foods, as they can alter the levels of creatinine in your urine, which is used as a reference for bone density calculations.
3. Stay Hydrated
Hydration is essential before a DEXA scan. Drink plenty of water in the days leading up to the procedure to ensure that your urine is clear. Clear urine is necessary to provide an accurate measurement of creatinine levels, which are used as a reference for bone density calculations.
4. Avoid Caffeine and Alcohol
Caffeine and alcohol can affect your bone density results. It is recommended to avoid consuming caffeine and alcohol for at least 24 hours before the DEXA scan. These substances can interfere with the accuracy of the measurements and may also affect your overall well-being during the procedure.
5. Wear Comfortable Clothing
Choose comfortable, loose-fitting clothing to wear during the DEXA scan. You may be required to change into a hospital gown, so it’s a good idea to bring something that is easy to put on and take off. Additionally, remove any jewelry, metal objects, and electronic devices that may interfere with the X-ray equipment.
6. Inform the Technician of Any Allergies or Medical Conditions
Before the scan begins, inform the technician of any allergies or medical conditions you may have. This information is crucial for their safety and to ensure that the procedure is performed correctly.
7. Prepare for the Scan
On the day of the DEXA scan, arrive at the appointment with a full bladder. A full bladder can help improve the accuracy of the measurements by providing a clearer image of the pelvic area. Follow any additional instructions provided by your doctor or the scanning facility.
By following these guidelines, you can help ensure that your DEXA scan is accurate and reliable. Always consult with your doctor for personalized advice and instructions before undergoing a DEXA scan.
