What is Obesity Surgery
Obesity is defined as an “Excessive fat accumulation in the body to the extent that health and well being are adversely affected”.
- People are considered obese when their body mass index (BMI) exceeds 27.5 kg/m2.
- As per BMI index it is a stage prior to morbid obesity.
- Overweight, obesity and morbid obesity are the fifth leading health risk for global deaths. At least 2.8 million adults die each year as a result of being overweight or obese.
- In addition, according to WHO, 44% of the diabetics, 23% of the ischaemic heart disease and between 7% and 41% of certain cancer are attributable to overweight and obesity.
What is Obesity/weight loss surgery?
- Obesity can be treated both medically and surgically. Medical treatments for obesity are quite time taking and difficult as the amount of weight loss is small and patients gain back most of the weight within no time.
- Surgeries designed to deal with weight loss in patients who are severely overweight and obese are called obesity and weight loss surgeries.
- However, controlled diet regimen and healthy lifestyle should be followed for best results of obesity and weight loss surgeries.
Types of Obesity Surgery
There are several types of restrictive, malabsorptive and combined procedures that can lead to sustained weight loss. Each one has its own benefits and risks. The top three procedures are:
- Gastric Banding A band is placed around the upper part of stomach to create a small pouch to hold food. The band limits the amount of food that the person eats by giving a feeling of fullness after eating small portions of food.
- Gastric Bypass It is a procedure which is both restrictive and malabsorptive. In this procedure a small pouch is created by using specially designed staplers.
- Sleeve Gastrectomy This is a restrictive procedure in which the stomach is stapled in such a way so as to create a long narrow sleeve.
