Obesity: A Disease
Obesity is emerging as a health epidemic around the world. According to the Center for Disease Control and Prevention, obesity is rapidly spreading across all regions and demographic groups. An estimated 97 million adults in the United States are overweight or obese. That figure represents more than 50% of the American adult population. Of this group, 11 million adults suffer from severe obesity.
Obesity is an excess of total body fat, which results from the caloric intake that exceeds energy usage. A measurement used to assess health risks of obesity is Body Mass Index (BMI).

The American Obesity Association reports that obese individuals have a 50-100% increased risk of death as compared to normal weight individuals, with 300,000 to 587,000 deaths each year. This substantial increase in health risks has made obesity the second leading cause of preventable death in the United States.

Dieting, exercise, and medication have long been regarded as the conventional methods to achieve weight loss. Sometimes, these efforts are successful in the short term. However, for people who are morbidly obese, the results rarely last. For many, this can translate into what’s called the “yo-yo syndrome,” where patients continually gain and lose weight with the possibility of serious psychological and health consequences. Recent research reveals that conventional methods of weight loss generally fail to produce permanent weight loss. Several studies have shown that patients on diets, exercise programs, or medication are able to lose approximately 10% of their body weight but tend to regain two-thirds of it within one year, and almost all of it within five years**. Another study found that less than 5% of patients in weight loss programs were able to maintain their reduced weight after five years*.
Why perform surgery for morbid obesity?
Morbid obesity surgery is not cosmetic surgery. All doctors recognize that once a patient’s weight exceeds a certain range they are more likely to suffer from a wide range of illnesses such as diabetes, sleep apnea, asthma, hypertension, arthritis, varicose veins and skin problems. Their chances of dying at a premature age are also greatly increased. Their employment prospects, mobility, and social acceptance also suffers. Depression is much more common in the morbidly obese. The main aim of this surgery is to bring your weight down to a safer range where most of these associated conditions are reduced in severity and many completely reversed. Along the way, most people find an improvement in their mobility, body image, self-esteem and enjoyment of life.
Gastrointestinal surgery for obesity, also called bariatric surgery, change the normal digestive process. The operations promote weight loss by decreasing absorption of nutrients and thereby reducing the calorie intake.
