Obesity: A Disease

Obesity is emerging as a health epidemic around the world. According to the centres 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 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. 

Causes of Obesity

Obesity could be a combination of the following:

• The genes you inherited from your parents
• How well your body turns food into energy
• Your eating and exercising habits
• Your surroundings
• Psychological factors

Consequences of Obesity

• If you are obese, severely obese, or morbidly obese, you may have:

Major health risks

• Shorter Life Expectancy
• Compared to people of normal weight, obese people have a 50% to 100% increased risk of dying prematurely
• Obese people have more risk for:
  - Diabetes (type 2)
  - Joint problems (e.g., arthritis)
  - High blood pressure
  - Heart disease
  - Gallbladder problems
  - Certain types of cancer (breast, uterine, colon)
  - Digestive disorders (e.g., gastroesophageal reflux disease, or GORD)
  - Breathing difficulties (e.g., sleep apnea, asthma)
  - Psychological problems such as depression
  - Problems with fertility and pregnancy
  - Urinary Incontinence

Risks to psychological and social well-being

• Negative self-image
• Social isolation
• Discrimination

Difficulties with day-to-day living

• Normal tasks become harder when you are obese, as movement is more difficult
• You tend to tire more quickly and you find yourself short of breath
• Public transport seats, telephone booths, and cars may be too small for you
• You may find it difficult to maintain personal hygiene

Treatment Options

Non-Surgical Treatment

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*.

Surgical Treatment

Over the years, weight-loss surgery has proven to be a successful method for the treatment of
morbid obesity#.  Surgical options have continued to evolve and is pleased to be able to offer
patients the BioEnterics® LAP-BAND® System surgery. This procedure is the least traumatic
and the only adjustable and reversible obesity surgery available in the United States. The
LAP-BAND System provides a unique tool that can help you achieve and maintain significant
weight loss, improve your health, and enhance your quality of life.
