Summary
The severe overweight is attributable in particular to increased retention of extracellular water caused by the cardiac insufficiency. Treatment with diuretic medication, for example, might reduce water retention, the progress of which can be monitored using the seca mBCA.
The patient has a very high BMI which is not attributable to an elevated fat mass, however, but to elevated extracellular water retention as a consequence of cardiac insufficiency, which needs to be reduced.
