When the kidneys are not functioning properly, the capacity to excrete sodium and water decreases, resulting in edema and high blood pressure. Hemodialysis is the method of removing waste from the blood to maintain a balance of electrodes in the body, and removing excess water by using a dialyzer (artificial kidney).

After a patient completes hemodialysis, the InBody may be used to check the extracellular water ratio (ECW/TBW) to ensure that the body water level has returned to a balanced state. Dialysis patients tend to show a significantly high ECW ratio when compared to a healthy person. This ratio drops significantly to a normal level after dialysis. InBody provides quantitative information about total body water, extracellular water, intracellular water, and the ECW ratio.

It has recently been reported that a higher ECW ratio of peritoneal dialysis and hemodialysis patients to residual renal function, inflammation, and malnutrition. This implies that body water balance monitoring of peritoneal dialysis patients is significant.


Diabetes is a metabolic disease that indicates insufficient insulin secretion or failure of insulin control. Blood glucose is used and stored in the muscles. A diabetic patient losing muscle mass is likely to have adverse effects on glycemic control. As leg muscles decrease, insulin resistance and risk of cardiovascular disease increase. Monitoring leg muscle mass is usually conducted by taking images of the thigh muscle area with a CT. While CT scans may expose patients to radiation, the InBody provides quantitative values of muscle mass in a much safer and convenient way.

The InBody is useful in monitoring muscle mass, especially in the legs, to maintain healthy glycemic control and to detect increases in ECW ratio, which could be due to deteriorating renal function.


Quantitative nutritional assessment is crucial as malnutrition is known to increase the risk of complications and mortality on patients. The InBody allows the monitoring of quantitative change in body composition against body weight during patient recovery.


Muscle mass data, provided by InBody, can be used for a wide range of applications. Fitness clubs, for example, can monitor changes in body fat and muscle. The effects of aerobic and strength exercises can be verified through objective data. Segmental muscle mass data is also highly useful in orthopedics and rehabilitation therapy. Therefore, it is significant to use the InBody Test to monitor the segmental muscle mass, in addition to rehabilitation therapy.

Liver Disease

The InBody Test may also be useful for cirrhosis patients with failing liver function, whose healthy liver tissues turn fibrotic due to chronic inflammation. In terms of body composition, the patients may suffer from ascites, the swelling of both legs due to body water retention. InBody can be used as an indicator for monitoring the ascites level and progress of hepatics disease through the monitoring of the patients ECW ratio.
