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.
- 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.
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)
- Cancer
- Depression
- 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.

| TREATMENT | WEIGHT LOSS (% OF PATIENTS) |
| Diet and Exercise* | 2% to 5% |
| Medication** | 0% |
| Bariatric Surgery*** | Bariatric Surgery*** 50% to 70% |
* 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).
There are several different bariatric surgery procedures, but the two general ways in which they work are restriction and malabsorption:
- Restriction limits the amount of food you can eat. Whether it is a gastric banding device around the stomach or a surgically-created, smaller stomach pouch, restriction ensures that the patient feels satisfied with less food.
- Malabsorption limits the number of calories and nutrients your body can absorb. During malabsorptive procedures, the surgeon reroutes the small intestine so that fewer calories and nutrients are absorbed.
Commonly performed bariatric procedures include:
- Gastric bypass
- Gastric banding
- Sleeve gastrectomy
- Biliopancreatic diversion with duodenal switch
Only you and your surgeon can decide if surgery is right for you.
To lose weight, your body must burn more calories than you eat and/or drink. A diet plan should be based on your health and lifestyle needs, and would include reducing the number of calories you take in. If you are considering this option, speak with your primary care physician about nutritional guidelines, and keep in mind that many bariatric programs also offer medically supervised weight loss programs.
Frequent and regular physical activity is beneficial to most anyone—whether they are pre- or postsurgery. Generally, an exercise program includes cardiovascular exercise such as walking, swimming, or cycling, strength training using resistance bands, weights, or machines, and stretching. Speak with your primary care physician before beginning any physical activity.
