Bioelectrical Impedance Analysis

Research has repeatedly shown us that body composition has a direct impact on the state of your health. Excess body fat is a risk factor for a number of issues, including diabetes, heart disease, and more. Bioelectrical impedance analysis (BIA) is a functional assessment that detects body composition imbalance in the early stages. As a result, there is a higher chance for successful intervention and treatment.

Bio-Impedance Overview

Bioelectrical impedance analysis measures the rate at which low-level electrical current travels though the body. Once the data is gathered, fat-free body mass is calculated. Next, your body fat percentage is determined by your height, weight, and gender.

How does bio-impedance work?

During your appointment, two electrodes will be placed on your right hand and foot. A painless, low-level electrical current is sent through the body. BIA uses resistance and reactance to determine your body composition. Let’s take a look at both of these factors.


Fat, muscle, bone, and water all present varying levels of resistance when an electrical current is passed through the body. For example, water is highly conductive, and it makes up a large percentage of the body. Therefore, the more water in the body, the less the resistance. Conversely, fat contains very little water. As a result, there is much higher resistance compared to body water or muscle mass.

Just as an interstate with more lanes allows traffic to flow faster, more water in the body allows electrical current to flow more easily. If there is less water in the body, the electrical current will take longer to travel.


Additionally, there is another type of resistance referred to as reactance. Every cell in the body is protected by a membrane that shields the inside of the cell from the outside environment.

Impedance is simply the vector sum of resistance and reactance. Our BIA equipment uses this information to determine your body composition.

Is bioelectrical impedance analysis safe?

BIA devices are considered safe for most individuals. However, those with implantable cardioverter defibrillators (ICDs) and pacemakers should not undergo this assessment.
