Weight loss surgery are on the forefront of many individuals' minds these days as weight is a hot topic in the news, magazines and talk shows. There are many different weight loss methods available to individuals who are looking to get rid of those extra pounds. Some may prefer to engage in dieting and exercise while others are interested in pursuing weight loss surgery as an option to lose weight. For those individuals considering weight loss surgery, the following paragraphs will highlight the effectiveness which has been noted in various types of weight loss surgery and briefly detail how these weight loss surgeries enable individuals to lose weight.


Effectiveness of Weight Loss Surgery


The effectiveness of weight loss surgery is something which will vary from individual to individual. There are many factors which affect how an individual will take to the procedure itself. Some of these factors include age of the patient, the patient's weight prior to having the surgery performed, the type of weight loss surgery performed, condition of the patient's health, ability to exercise after the surgery, ability to follow diet and nutrition guidelines and how motivated and determined an individual is to lose the weight and keep it off.


When medical health professionals look to the individual to determine if their weight loss surgery was successful or not and how much of a success it was they will look to see if the patient has achieved a loss of 50% or more their excess body weight. In addition, the patient will have had to keep that weight loss level over the course of 5 years. The studies which have been performed have shown the general effectiveness of weight loss surgeries overall. In general, many patients have shown a weight loss of 30-50% of their excess body weight after only 6 months post-surgery and around 77% at 1 year or so.


Another factor which determines the effectiveness of weight loss surgery in general is the body mass index (BMI) of the individual prior to having the surgery performed. If an individual had a BMI that was not as high, they are more likely to be able to reach their target goal through weight loss surgery.


The effectiveness of weight loss surgery also depends on the type of surgery itself. For vertical banded gastroplasty, studies have shown that individuals can maintain 50% of their excess weight loss after 10 years post-surgery. With regard to malabsorptive procedures, individuals who undergo this form of weight loss surgery may see a range of 74% excess weight loss at one year post-surgery to around 91% at the fifth year after surgery has been performed. For weight loss surgery which is a combination of restrictive and malabsorptive procedures, an individual may experience around 77% excess weight loss at only one year post-procedure. When it comes to the effectiveness of laparoscopic adjustable Gastric Banding, individuals who have this surgery performed may see an excess weight loss at 2 years anywhere from 28-87% as the results vary greatly in different patients.


How Weight Loss Surgery Helps Individuals to Reduce Their Weight


When individuals ask the question regarding how weight loss surgery helps individuals lose weight, the answer is varied. How weight loss occurs due to weight loss surgery depends greatly on the specific surgery which is performed. In order to truly understand how weight loss surgery enables individuals to lose weight, it is important to look at both restrictive and malabsorptive weight loss surgeries individually.


The basis of weight loss with regard to restrictive weight loss surgery methods is that restrictive surgery helps individuals reduce their weight by decreasing the food intake. By surgically taking measures to enable individuals to feel full more quickly, those individuals who have undergone the surgery will not eat as much as their hunger will be satiated in a more expedient manner. In restrictive surgery procedures, the stomach portion is stapled or sectioned into two parts where the food will enter the smaller portion. Since there is only so much room for the food to fit into post-operation, those who eat their meals will eat less, as they will fill up more quickly. Also, the calories which the individual will be taking in after having this surgery performed will be significantly less than before.


It is important to note that an individual will not immediately adjust to their new stomach size. They will need to follow a certain diet and nutritional guidelines once they have had the restrictive surgery performed. In addition, the patient will need to establish new and improved eating habits in order for that individual to see the best results possible. Simply by having this surgery performed does not mean that the individual is free to eat whatever they want and go without exercise. The patient will need to eat right, work out and alter their former eating habits in order to make the new stomach work correctly.


As for the malabsorptive weight loss surgeries, these procedures are ones which alter the digestion of an individual in order to promote weight loss. These procedures, by altering the digestion routine of an individual, will prompt food to be poorly digested and prevent it from being absorbed all the way. Individuals lose weight via these malabsorptive methods and the food is being eliminated in the stool prior to being absorbed into the body. Since the food is not absorbed, neither are much of the calories. These types of procedures are frequently more successful than restrictive procedures and when used in conjunction with restrictive procedures, those individuals see the best results.


Weight loss surgery effectiveness and how it reduces overall weight varies from procedure to procedure and individual to individual. It is important to review effectiveness and weight reduction concepts of each weight loss surgery option prior to settling on a specific one.
