Obesity is defined as the accumulation of fat in amounts greater than desired, to an extent that may cause illness or worsen an existing disease.
The most commonly used index for assessing obesity and its severity is the Body Mass Index (BMI). This index is calculated by the ratio between height and weight squared.
General Information
However, BMI is not the whole picture. When assessing the relationship between obesity and illness, one must take into account chronic diseases, age, family history, eating habits, the type of obesity, and more.
With this index, it is possible to determine whether a person is at a normal weight, underweight, overweight, or obese.
The index is calculated as follows: weight (in kilograms) divided by height squared (in meters).
Below is the BMI value table and weight classifications:
Up to 18.5 - Underweight and at risk for malnutrition.
18.5-24.9 Normal weight and relatively low risk of diseases related to obesity.
25-29.9 Overweight.
30-34.9 - Obesity Grade I.
35-39.9 - Obesity Grade II.
40 and above - Obesity Grade III.
Therefore, overweight is a state in which the individual's BMI ranges between 25-29.9
The recommended solution before bariatric surgery is to consult a dietitian, so that they can provide initial support through dietary changes, interpretation of blood tests, guidance on recommended foods, and advice on physical activity to promote real and long-term change.
In extreme cases, additional treatments may help and include medications, endoscopic treatment, or bariatric surgery.
Jenny Vosko, clinical dietitian, expert in gastro-nutrition and diabetes nutrition, has supported patients for over a decade after endoscopic treatments, providing them with knowledge, tools, and methods for healthy and proper eating to enhance the effect of the treatment and help sustain it over time.
