Calculate your Body Mass Index (BMI)

Your weight (kg) Your height (m) BMI    From 20 to 25 : normal weight    From 25 to 30 : over weight    From 30 to 35 : obesity    From 35 to 50 : hyperobesity    Over 50 : superobesity

Body Mass Index is a ratio based on your weight and your height which will help determine whether you have medical risk factors  (diabetes, arterial hypertension, cardiovascular disease, osteoarthritis) related to overweight.

If your Body Mass Index is superior to 28 and lower than 40 you can consider the placement of an intra gastric balloon.
