Body water
Note:
People with a high body fat value very often have a body water value below that of the
WHO guidelines. Sportsmen and women with little body fat and high muscle mass often
exhibit values above these guidelines. In infants, water makes up 75 % of body weight.
This proportion then drops to 65 % by the end of the growth period and in old age is near-
er 55 %. (Source: Schmidt, Thews, Physiologie des Menschen [Human physiology], 25th
edition, Springer-Verlag in Berlin and Heidelberg, 1993).
The measured values will only give indications of possible irregularities in the water and
fat values of your body. The precision of the measurement depends on various influenc-
ing factors. If you notice deviations from the standard values, please ask your doctor for
a differential diagnostic examination.
Evaluating Body Mass Index for adults:
Compare the value determined with the categories quoted below which correspond to
those used by WHO, 2000.
• BMI below 18.5:
Warning, this patient weighs too little. There could be a tendency to anorexia. An in-
crease in weight is recommended to improve well-being and performance. If in doubt,
consult a specialist.
• BMI between 18.5 and 24.9:
The patient is of a normal weight. He can stay as he his.
• BMI between 25 and 30 (pre-obese):
The patient is slightly to moderately overweight. He should cut his weight if he is
already ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
• BMI over 30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all
under strain. A consistent diet, plenty of movement and behavioural training are all
recommended. If in doubt, consult a specialist.
6. Cleaning
Clean the surface and the housing as required using a domestic cleaning agent or commer-
cially-available disinfectant. Follow the manufacturer’s instructions.
Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for
cleaning. Such substances can damage the high-quality surfaces.
Women 50 – 55%
Men 60 – 65%
Children 65 – 75%
