Evaluation Of Results; Body Water - Beurer BG 21 Mode D'emploi

– Stand still during the measurement.
– Wait several hours after unusually strenuous activity.
– Wait approx. 15 minutes after getting out of bed so that the water in your body can be distributed.
– Remember that only long-term trends are important. Short-term changes in weight within a few days are usually
caused by a loss of fluid. Body water plays an important role towards our general wellbeing.
The measurement is not reliable for:
– Children under approx. 10 years of age.
– Competitive athletes, bodybuilders.
– Pregnant women.
– Persons with fever, undergoing dialysis, with symptoms of edema or osteoporosis.
– Persons taking cardiovascular medication.
– Persons taking vascodialating or vascoconstricting medications.
– Persons with substantial anatomical deviations in the legs relative to their total height (leg length considerably
shorter or longer than usual).
The measuring principle
This scale works on the principle of B.I.A. (bioelectrical impedance analysis). This involves the calculation of body
content within seconds, using a current that is not noticeable, is completely non-hazardous and does not pose
any risk.
When this measurement of the electrical resistance (impedance) is considered alongside constants and/ or indi-
vidual values (age, height, gender, activity level), the body fat percentage and other variables in the body can be
calculated. Muscle tissue and water conduct electricity well and therefore have a lower resistance. In contrast,
bones and fat tissue have low conductivity as the fat cells and bones are barely able to conduct the current due
to very high levels of resistance.
Please note that the values calculated by the diagnostic scale only represent an approximation of the actual medi-
cal analytical values for the body. Only a specialist doctor can precisely establish the body fat, body water, muscle
percentage and bone structure using medical methods (e.g. computer tomography).

A lower value is often found in athletes. Depending on the type of sports, training intensity and physical constitu-
tion, values may result which are below the recommended values stated.
It should, however, be noted that there could be a danger to health in the case of extremely low values.
