The Obesity Epidemic

According to the Surgeon General’s recent “call to action”, obesity has reached nationwide epidemic proportions. Obesity is defined as an excess of total body fat, a result of imbalance between caloric intake and energy expenditure. In 1999, an estimated 61 percent of U.S. adults were overweight, along with 13 percent of children and adolescents. Obesity among adults has doubled since 1980, while the number of overweight adolescents has tripled. Increases in obesity are associated with dramatic increases in conditions such as type 2 diabetes and asthma. In addition, a recent study reported that obesity causes more deleterious effects on health than either smoking or problem drinking. The increase in chronic health conditions caused by obesity is similar to that seen in 20 years of aging.

Obesity can be a degenerative and debilitating disease. The National Institutes of Health reports that obesity substantially increases the risk of morbidity and mortality from:

• Heart disease
• Diabetes (type 2)
• Stroke
• High blood pressure
• Sleep apnea
• Cancer
• Breathing difficulties
• Joint problems

Among individuals who are diagnosed with type 2 diabetes, 46 percent are obese. Among those with high blood pressure, 38 percent of men and 32 percent of women are obese. Of those diagnosed with high blood cholesterol, 20 percent of men and 25 percent of women are obese. According to the American Obesity Association, obese individuals have a 50 percent to 100 percent increased risk of death compared to individuals of normal weight, with obesity reportedly causing 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.

Measuring Obesity

A measurement used to assess obesity health risks is Body Mass Index (BMI). BMI is calculated by dividing body weight in pounds (lb) by height in inches squared (in²) and multiplying that amount by 704.5. The metric calculation for BMI is kg/m². Although health risks increase at a BMI of 27, significant health problems and increased risk of death are greater as a person’s BMI increases. Obesity is defined as a BMI of at least 30, severe obesity is associated with a BMI of at least 35, and morbid obesity with a BMI of 40 or higher.

Economic Impact of Obesity

The economic impact of obesity in the United States is substantial, estimated at approximately six percent of our national health expenditure. As obesity continues to grow, so do healthcare costs. The American Obesity Association states that obesity-related costs exceed $200 billion per year in the United States alone.

Diet, exercise and pharmaceuticals are the primary non-surgical treatments of obesity. Americans spend more than $33 billion annually on weight-loss products and services. However, these programs have a failure rate of up to 95 percent after five years. Studies indicate that people who complete non-surgical weight loss programs and lose approximately 10 percent of their body weight gain one third of it back within one year and almost all of it back within five years*. There is little evidence to suggest that any non-surgical treatment will achieve significant, but more importantly, sustained weight loss in the severely obese.

Treating Obesity with the LAPBAND® System

Seriously overweight patients who have never been able to keep pounds off with diet pills, special meals or other weight-loss programs now have a safe and effective, minimally invasive weight-loss surgery option that significantly reduces food intake. The LAPBAND System creates an earlier feeling of fullness and limits food consumption. The only adjustable and reversible weight-loss surgery available in the United States, the LAPBAND System, is inserted laparoscopically, without cutting or stapling the stomach, or gastrointestinal rerouting to bypass normal digestion. Since the Food and Drug Administration’s approval of the LAPBAND System in June 2001, interest in and use of gastric banding has been rapidly growing in the United States. To date, more than 150,000 patients worldwide have undergone LAPBAND surgery.
