Bioelectrical Impedance Analysis (BIA)

Bioelectrical Impedance Analysis (BIA) is a quick and painless test that estimates your body composition — how much fat, muscle, and water your body contains — by sending a tiny, harmless electrical signal through your body. It takes just a few minutes and involves standing on a special scale or holding sensors while the machine calculates your results.

Bioelectrical Impedance Analysis is a non-invasive method for estimating body composition that measures the impedance (resistance and reactance) of body tissues to a low-level alternating electrical current. Because lean tissue containing water and electrolytes conducts electricity well while fat tissue acts as an insulator, BIA uses predictive equations incorporating height, weight, age, and sex to derive estimates of total body water, fat-free mass, and fat mass.

BIA provides a more complete picture of your health than weight alone, helping Dr Joseph Wang and the Accord Medical team track whether your weight loss is coming from fat rather than muscle — a critical distinction for designing effective, personalised treatment plans.
