[Specific weight loss in hyper- and hypothyroidism (author's transl)].
By means of a new method of extremely precise weight measurement (buoyancy scale) it is possible to measure the continuous weight loss of the human body. This weight loss is made up of three components, viz. the weight difference between produced CO2 and consumed O2, water loss through the lungs and transpiration through the skin. In relation to body weight it is called "specific weight loss." This parameter was measured in healthy human subjects and found to be within a relatively narrow range (16.42 plus or minus 2.55 mg/min/kp body weight). In four patients with hypothyroidism the values were very low (5.5 to 8.5 mg/min/kp). An increased specific weight loss was found in patients with hyperthyroidism (38 to 102 mg/min/kp in clinically severe cases). The applicability of this method to examination of thyroid function is discussed. It is compared to the classical method of basal metabolic rate measurement and its advantages are enumerated.
