Monitoring of nutritional status in patients with chronic kidney disease

It is important that your nutritional status is checked regularly, particularly in later stages of chronic kidney disease (predialysis stage 4 to 5, and dialysis), when the risk for protein-energy-malnutrition and for fluid overload increases.

Assessment tools for the monitoring of nutritional status

You can quantify some basic measurements by yourself: body weight and body mass index (BMI). However, their validity concerning your nutritional status is limited, because they don´t give information about the composition of your body tissues. For example, if you suffer from fluid overload, your body weight and BMI will increase, but at the same time you can be malnourished and suffer from muscle degradation. Thus, body weight and BMI are essential measurements to get an approximate hint about your nutritional status, and they can be measured easily. Particularly in dialysis, daily measurements of body weight are crucial to monitor the fluid load of your body.

Monitoring

To get more precise information about your nutritional status, your doctor may perform some additional measurements.
