Body Composition Analysis

Why is body composition analysis an effective tool for disease prevention? Early identification of disease onset is imperative for patient care by providing practitioners with tools to develop interventions to improve long-term health outcomes. InBody devices are space-efficient, are easy to incorporate into patient screenings and the data can easily be implemented into patient management software. The InBody test provides a comprehensive printout that serves as an ideal educational tool for engaging patients in understanding health risk management and reduction. In less than 60 seconds, an InBody Test can provide easy-to-understand, accurate, and objective measurements to evaluate a patient’s disease risk. Doctors and nurses can use the InBody to:

  • Monitor muscle, fat, and visceral fat to provide an accurate measure of health risk
  • Assess muscle distribution to determine patient-specific health risks related to disease and frailty
  • Identify fluid imbalances related to specific diseases
  • Track changes for more effective long-term risk identification and reduction


Measure lean mass distribution to identify risk of frailty
Due to the rising prevalence of sedentary, inactive lifestyles, patients are more likely to become frail or suffer from injuries leading to reduced mobility. Evaluate lean mass distribution and identify imbalances to prevent or treat sarcopenia and improve physical function.

Chronic inactivity and poor diet have deleterious effects on body composition, eventually impacting physical function and quality of life. Sedentary lifestyles cause degenerative loss of muscle mass, increasing risk of falls and mobility issues as a patient ages. The InBody measures lean body mass in each segment of the body separately, allowing identification of insufficient development or muscular imbalances. These objective measures of lean mass distribution and development provide practitioners with information to identify increased risk of frailty and develop targeted recommendations for maintaining functional mobility.


Monitor Excess Fat Mass

MUSCLE-FAT AND VISCERAL FAT ANALYSISDoctors rely on the use of BMI to assess health risk. Assess muscle and fat composition separately to evaluate to nutrition status and examine the patient’s current health risks.

Measuring body composition allows the practitioner to break body weight down into separate compartments of muscle and fat mass, both independent contributors to functional status, insulin sensitivity, and health risk. Identifying patients who have low muscle mass or a combination of low muscle and high fat mass (sarcopenic obesity) can help provide earlier interventions for reducing cardiometabolic risk.

Excess fat mass can also be easily identified across the whole body, while separate assessment of visceral fat mass can help practitioners further assess patient-specific health risks. By using the Muscle-Fat Analysis and Visceral Fat sections of the InBody Results Sheet, the physician will be able to perform a more specific health risk assessment.


Monitor Fluid Accumulation in each Body Segment

Although disease risk is often associated with inflammation, diagnostic markers of fluid retention SEGMENTAL ECW/TBW WATER ANALYSISand inflammation are time consuming and inconvenient. InBody’s technology is able to precisely track fluid changes across the body to understand the cause of imbalanced fluid levels.

InBody effectively distinguishes water in the intracellular (ICW; within the tissues) and extracellular (ECW; within the blood and interstitial fluids) compartments that make up total body water (TBW). The Edema Index, based on the ratio between ECW and TBW (ECW/TBW), can be used to distinguish fluid imbalances resulting from malnutrition or edema. Managing increases in Edema Index is a priority for improving patient outcomes.

Due to the high water content of muscles, loss of muscle mass causes a reduction in ICW and results in an increased Edema Index. Thus, the Edema Index can be used to identify muscle loss and its link to associated health conditions. Since cardiovascular disease is associated with increased systemic inflammation, progressing fluid imbalances, the Edema Index can be used to identify and monitor long-term fluid retention, which may lead to comorbidities such as renal or cardiac dysfunction. Monitoring the Edema Index can help physicians understand disease-related fluid imbalances more accurately.


Track changes in muscle, fat, and fluid balance to chart progress

BODY COMPOSITION HISTORYGeneral practitioners do not see patients enough to subjectively monitor critical changes to patient health through tools such as BMI or physical assessments. By tracking body composition history, doctors can detect changes that can aid in patient education and earlier detection of disease.

It is often difficult to detect subclinical changes to a patient’s health status, such as muscle loss and inflammation, with a physical exam. These changes are often minimal in early stages of disease and are combined with an increase in fat mass or fluid accumulation, which may mask indications of disease or result in an underestimation the severity of the condition when looking at weight alone. Tracking changes to muscle mass, fat mass, and the Edema Index allows health care providers to educate patients regarding their health risks and set goals to improve body composition and overall health.

Why do Health Professionals Trust InBody?

All InBody professional body composition analyzers rely on four pillars of technology to deliver quick, accurate and precise results. These pillars allow you to trust that the results reflect your patients’ true health from the inside out.


Direct Segmental Measurement BIA (DSM-BIA) allows for muscle mass and fat mass readings in each segment of the body: right arm, left arm, right leg, left leg and trunk. By measuring each segment of the body separately, the InBody is able to provide an in-depth analysis of a patient’s fluid balance for each region. These outputs include intracellular water, extracellular water and ECW/TBW ratio. Objective measures of intracellular and extracellular water can identify edema in a certain limb, while Segmental ECW/TBW can reveal circulation issues that result from a diabetes, renal or heart failure, or other health complications. This allows InBody to create better diagnoses and catch disease progression earlier.


InBody devices use multiple frequencies to measure body water more accurately than physical examinations. These high and low frequencies are able to measure both intra- and extracellular water, producing more precise measurements of body water compartments. Having an accurate measure of the different water compartments can indicate fluid imbalances or water retention stemming from circulation issues and can be used to monitor changes in fluid balance to monitor disease progression.


InBody devices used 8-Point Tactile Electrodes to ensure that measurements always start in the same place, test after test. This technology creates precise and reproducible results, ensuring that the changes to the results over time are comparable and genuine.


InBody devices do not rely on empirical or pre-loaded data. Age, gender and ethnicity do not contribute to an individual’s results, an important factor for general practitioners, an important factor for general practitioners as every patient is unique. By not relying on pre-loaded data, general practitioners can be confident that the data they are obtaining on their patient is reflective of that patient alone. Therefore, any changes that are happening to a patient reflects a genuine change in their body composition.
