What is a Dexa Scan?

Dexa Scan data will help us define your overall health. It goes a long way beyond the simple calculating of your body weight. A Dexa Scan is a simple noninvasive process requiring about half an hour of your time here at Advance Surgical. It gives you an accurate interpretation of how much muscle and fat you have and where you are carrying it. It will also work out your bone density and give an assessment of your metabolic rate.

Muscles and fat

Your Dexa Scan is very accurate and a good foundation to see how healthy you are. If you are considering weight loss surgery, the Dexa Scan allows us to assess your muscle mass prior to the procedure and this can be monitored post operatively to assist you in muscle maintenance. We know that if some patients are not careful they can lose significant amounts of muscle with weight loss procedures.

If you’re not looking for weight loss, but simply wanted to get reliable information on your overall health, then our dietitians and exercise physiologists will be ready to give you a detailed summary of your scan results and how to make changes going forward.

Using X-Rays?

Yes, the Dexa Scan uses the X-Ray technology, but the amount of rays is the equivalent of 2 days of background radiation, and much lower level than a typical chest X-Ray. Dexa Scans are an approved medical procedure and can be safely used to obtain a detailed overview of your muscle mass and fat distribution as well as accurate bone density.

Why do we want to know all this?

At Advance Surgical, we believe that healthy living goes way beyond the dry numbers of our BMI and our body weight. More detailed information about the amount of muscle mass we have, helps us understand our metabolism and allows us to look at our health in a more responsible way. Finding out about the potential risks of carrying too much fat in the wrong place is an invaluable step towards an improved overall health. So if you want to get clear about your body, come and see us for a Dexa Scan, at Advance Surgical.
