How Effective Is Weight-Loss Surgery?
Obesity is a medical condition in which a person accumulates excessive weight and it starts to adversely affect the health of the individual. There are several methods to estimate the extent of obesity. The most widely accepted methods are Body Mass Index (BMI) and waist-hip ratio.
The BMI of an individual can be obtained by measuring the ratio of an individual’s weight and height. If the result is more than 30, the individual is considered as obese. The ration can get as high as 45, this comes under ‘morbidly obese’ category. Any individual having BMI greater than 40 is considered as suitable candidate for weight loss surgery. If an individual’s BMI falls in the range of 30 to 40, with one or more morbid conditions, then they can also be considered for weight reduction surgery. Weight loss surgeries are a group of surgical methods that involves altering the digestive system of the individual.
The most important question remains regarding the effectiveness of these procedures. The answer is very effective and long lasting. The weight loss surgeries aims to reduce the overall weight of the individual. Instead of extracting out fat from the fat zones of the body, it makes permanent changes to the entire body.
Let’s understand how these surgical procedures works and remain effective even after the completion of the surgery.
There are several methods of performing weight loss surgery. In some of these methods, such as gastric sleeve, the stomach is reduced up to 25 percent of it original size. This reduced stomach size provides lesser room for storage of food, which causes the person to eat less and thus it limits the amount of food one can eat. In long run, the individual consumes lesser amount and thus, their weight remains in check.
Another most effective weight loss surgery procedure is gastric bypass surgery. It is also known as Roux-en-Y method. In this procedure, the stomach is reduced up to 15 percent of its original volume and also the small intestine is cut and bypassed to smaller stomach pouch. The remaining stomach is left to produce digestive juice which meet with the partially digested food in the small intestine. The smaller stomach pouch ensures lesser intake of food and smaller small intestine ensures lesser absorption of nutrients by the body.
Each of these weight loss surgery procedure remains effective up to a lifetime. These are performed extensively by laparoscopic approach in this age. It is becoming a magic solution for the people struggling with obesity for a long time.
