Composition Scan

The gold standard in measuring fat mass and lean muscle distribution.

What is a DEXA body composition scan?

DEXA, which stands for Dual X-ray Absorptiometry, is one of the most accurate methods for analysing the amount and distribution of body fat, bone and lean muscle mass. 

If your goal is to change your body composition (like muscle-to-fat ratio), a DEXA scan can help. It offers more insight than what you see on regular scales. It shows not just weight changes but also how much fat you’re losing or gaining compared to your muscle mass.

DEXA can detect dangerous deep visceral fat

Most of the fat on our body is subcutaneous fat, stored under the skin surface. 

Visceral fat is hidden, stored deep inside your body around internal organs including the heart, liver and intestines. Visceral fat can be harmful to your health as it produces chemicals and hormones and can trigger inflammation. Having too much visceral belly fat has been shown to increase your risk of a number of chronic health conditions including heart disease, dementia, type 2 diabetes, liver disease and some types of cancer.

Unlike subcutaneous fat, you cannot see or feel visceral fat. DEXA is one of the most reliable methods for measuring hidden visceral fat.

Whilst radiation levels are very low, DEXA scans and X-rays are not recommended for pregnant women as significant body composition changes during pregnancy remove the usefulness of the results.
