What are the degrees of obesity that exist?
Beyond being only a problem related to aesthetics, to talk about obesity is to make it a focus of multiple disorders seriously harmful to health.
But not only obesity, but also overweight, which is defined as the “abnormal or excessive accumulation of fat harmful to health”, which can bring a whole series serious consequences for the human body, and even fatal .
Deepening a little in that last point, there are studies which indicate that people between 40 and 70 years who register a weight greater than 30% of the ideal, suffer a quite significant increase in mortality; up to 42% in men and 36% in women.
It is necessary to understand that the main reason for obesity and overweight is the presence of an energy imbalance in the relationship between the calories that are consumed and those we spend.
In order to diagnose the disease worldwide, the degrees of obesity of the World Health Organization (WHO) are used. Identifying if someone is overweight is really simple, because for this there is the so-called Body Mass Index (BMI).
It is an indicator which relates the weight and height, for which it is calculated by dividing the weight of a person (in kilograms) by the square of its size (in meters). In this way, every person with a BMI between 25 and 29.9 kg / m2, is considered as someone who is overweight. Above 30 BMI, there is already talk of obesity.
The WHO obesity degrees are the following:
- BMI <18 Insufficient weight BMI 18.5 – 24.9 Normopeso BMI 25 – 26.9 Overweight grade I BMI 27 – 29.9 Overweight grade II (overweight)
- BMI 30 – 34.9 Obese type I (Obesity type I) BMI 35 – 39.9 (Obesity type II) BMI 40 – 49.9 (Type III Obesity / Morbid Obesity)
- BMI> 50 (Type IV Obesity / Superobesity)
It should be noted that the term “morbid obesity” was incorporated in the year 1963, this with the aim of emphasizing those diseases associated with extreme obesity that justify the performance of therapeutic intervention. On the other hand, people are in obesity grade II, III or IV, are candidates for surgical treatment.
