Most of the weight reduction programs for non-surgical means, are based on some combination of diet, behavior modification and regular exercise. It is estimated that less than 5% of obese people who participate in a weight reduction program strictly for non-surgical means, lose a significant amount of weight and maintain that loss for a period of 5 years. According to the National Institutes of Health in several countries, over 90% of people participating in these programs regain their previous weight, in the course of a year.
For morbidly obese patients it’s even more difficult to maintain weight loss because of poor results with diets. This produces discouragement and low self-esteem of the patient, as they get minimal weight loss and then a rebound effect that makes them gain all lost weight. This effect is characterized in that experience, perhaps the best weight loss and this loss once achieved, with a long-term approach of months, you start to regain weight in a minimum. You cannot get a sustained long-term effect, but fluctuations in body weight at the end, not be effective lead to a loss of self-esteem, depression and high anxiety.
The fact is that morbid obesity is still a complex multifactorial chronic disease. Surgery for weight reduction, compared with other medical treatments, has provided the longest period of weight reduction on a sustained basis in patients who have failed all therapies.
For many patients, the risk of death for not being operated is greater than the risks of possible complications that may occur after these bariatric procedures. It is important to note, that with the advancement in the techniques of stapling and laparoscopic surgery, they have reduced post-surgical complications, very significantly.
