BMI Evaluation
Under 18.5
The patient is underweight. There might be a tendency to
anorexia. It is advisable that the patient puts on weight to
improve well-being and performance. If in doubt, a medical
specialist should be consulted.
Between 18.5 and
24.9
The patient's weight is normal.
Between 25 and 30
(pre-obesity)
The patient is slightly to moderately overweight and should
lose weight if already suffering from disease (e.g. diabetes,
high blood pressure, gout, disorders of the fat metabolism).
Over 30
The patient urgently needs to lose weight as this is putting a
strain on the metabolism, circulation and skeleton. The
recommendation is for careful adherence to a diet, plenty of
exercise and behavioural training. If in doubt, a medical speci-
alist should be consulted.
