Weight Loss surgery, also known as Bariatric Surgery, is a procedure aimed at allowing patients of obesity to lose weight effectively and permanently. It can only be performed in extreme cases where the patient’s weight poses a clear health risk and the excess weight is at a point where it cannot be lost through natural ways. The Body Mass Index (BMI) formula is used to determine whether a patient is obese or not. Weight Loss surgery is performed in patients with a BMI of 35 or above, while in some cases this threshold is reduced to 30 if the patient has chronic illnesses such as diabetes.
The calculation of the patient’s Body Mass Index is done by dividing the patient’s weight by their squared height. A patient with a height of 1.78 meters and a weight of 90 kilograms will calculate their BMI as:
The type of surgery required may vary depending on the patient’s condition. Different types of Weight Loss surgery include restrictive surgery, in which the volume of the stomach is reduced, malabsorptive surgery, which aims to limit the amount of nutrient absorption, and combined surgery in which both methods are used in combination.
WHY IT’S DONE
Being obese can lead to many health problems such as heart disease, diabetes and some types of cancer. Staying at a healthy body mass index will significantly reduce the risk of such health problems. Studies show that weight loss expectancy of patients can be as great as 80 percent after Weight Loss surgery, while this number is a mere 7-10 percent in patients who choose dieting as opposed to surgery as their treatment method.
