Defining Morbid Obesity
Obesity is a serious disease with symptoms that build slowly over an extended period of time. The National Institutes of Health (NIH) define morbid obesity as:
– Being 100 pounds or more above your ideal body weight
– Or, having a Body Mass Index (BMI) of 40 or greater
– Or, having a BMI of 35 or greater and one or more co-morbid condition
The disease of morbid obesity interferes with basic physical functions such as breathing or walking. Long-term implications of the disease include shorter life expectancy, serious health consequences in the form of weight-related conditions such as type 2 diabetes and heart disease, and a lower quality of life with fewer economic and social opportunities.
Obesity is a serious public health issue in the U.S.
– 24 million U.S. adults are living with morbid obesity and may qualify for Bariatric surgery based on NIH guidelines.32
– By 2010, it's projected that there may be 31 million U.S. adults living with morbid obesity and may qualify for Bariatric surgery based on NIH guidelines.32
The presence of obesity increases the risk of a number of medical conditions, including cancer. A co-morbid condition is a health condition related to a primary disease such as obesity.
There are many health conditions related to morbid obesity, but some of the most common are:
– Type 2 diabetes, which can lead to heart disease, kidney failure, blindness, amputation of the feet or legs, and nerve damage
– Heart disease, such as hardening of the arteries, heart attack, and angina
– High blood pressure, which can lead to heart disease, stroke, kidney failure, and vision loss
– High cholesterol, which can lead to heart disease, stroke, and kidney failure
– Obstructive sleep apnea has been associated with high blood pressure
– Acid reflux/GERD, which can lead to esophagitis, Barrett's esophagus, and esophageal cancer (adenocarcinoma)8
– Osteoarthritis and joint pain, which can lead to loss of mobility
– Stress urinary incontinence
– Female reproductive health disorder, which can lead to infertility and sexual dysfunction
An emerging body of literature demonstrating relationships between maternal obesity and structural birth defects, including:
– Increased risk of spina bifida and heart defects
– Decreased risk of gastroschisis
These conditions occur more frequently in people with morbid obesity. Mortality rates from many of these conditions are also higher among people with morbid obesity.
Results of Five-Year Follow-up
(% OF PATIENTS)
Diet and Exercise*
2% to 5%28
50% to 70%28
* Success measured as a loss of 10 percent of initial body weight.
** Weight loss is not maintained once treatment ends.
*** Success measured as a loss of 50 percent of excess body weight (equivalent to loss of approximately 20 to 25 percent of initial body weight).
The above chart compares the long-term effectiveness of three different obesity treatments: diet and exercise, weight loss medications, and bariatric surgery.
– Bariatric surgery clearly has the best weight loss outcome compared to the other two treatments—50 to 70 percent of people were able to lose at least 50 percent of the excess weight and keep it off for five years.
– After five years, only 2 to 5 percent of the people who dieted and exercised had maintained a weight loss of at least 10 percent.
– People who had taken weight loss medications were not able to maintain any weight loss.
