About Morbid Obesity

Morbid obesity is a chronic disease, meaning that its symptoms build slowly over an extended period of time. An estimated 5-10 million Americans are considered morbidly obese. Obesity becomes "morbid" when it reaches the point of significantly increasing the risk of one or more obesity-related health conditions or serious diseases (also known as co-morbidities) that can result either in significant physical disability or even death.

Weight loss surgery is major surgery. Its growing use to treat morbid obesity is the result of three factors: Our current knowledge of the significant health risks of morbid obesity; the relatively low risk and complications of the procedures versus not having surgery; and the ineffectiveness of current non-surgical approaches to produce sustained weight loss. This site will provide valuable information about the benefits and risks of weight loss surgery. However, the best way to get a full assessment of your condition is to schedule a consultation to determine if weight loss surgery may be an option for you.

1. Am I Morbidly Obese?

Answering this question may give you the courage you need to take the first step. Below are tools you can use to determine if you are morbidly obese and potentially a candidate for weight loss surgery. There are several medically accepted criteria for defining morbid obesity. You are likely morbidly obese if you are:

1. more than 100 lbs. over your ideal body weight, or
2. have a Body Mass Index (BMI) of over 40, or
3. have a BMI of over 35 and are experiencing severe negative health effects, such as high blood pressure or
4. diabetes, related to being severely overweight
5. unable to achieve a healthy body weight for a sustained period of time, even through medically supervised dieting

2. Causes of Morbid Obesity

The reasons for obesity are multiple and complex. Despite conventional wisdom, it is not simply a result of overeating. Research has shown that in many cases a significant, underlying cause of morbid obesity is genetic. Studies have demonstrated that once the problem is established, efforts such as dieting and exercise programs have a limited ability to provide effective long-term relief.

Science continues to search for answers. But until the disease is better understood, the control of excess weight is something patients must work at for their entire lives. That is why it is very important to understand that all current medical interventions, including weight loss surgery, should not be considered medical cures. Rather they are attempts to reduce the effects of excessive weight and alleviate the serious physical, emotional and social consequences of the disease.

1. Contributing Factors

   The underlying causes of severe obesity are not known. There are many factors that contribute to the development of obesity including genetic, hereditary, environmental, metabolic and eating disorders. There are also certain medical conditions that may result in obesity like intake of steroids and hypothyroidism.

2. Genetic Factors

   Numerous scientific studies have established that your genes play an important role in your tendency to gain excess weight.

   1. The body weight of adopted children shows no correlation with the body weight of their adoptive parents, who feed them and teach them how to eat. Their weight does have an 80 percent correlation with their genetic parents, whom they have never met.
   2. Identical twins, with the same genes, show a much higher similarity of body weights than do fraternal twins, who have different genes.
   3. Certain groups of people, such as the Pima Indian tribe in Arizona, have a very high incidence of severe obesity. They also have significantly higher rates of diabetes and heart disease than other ethnic groups.

   We probably have a number of genes directly related to weight. Just as some genes determine eye color or height, others affect our appetite, our ability to feel full or satisfied, our metabolism, our fat-storing ability, and even our natural activity levels.

3. The Pima Paradox

   The Pima Indians are known in scientific circles as one of the heaviest groups of people in the world. In fact, National Institutes of Health researchers have been studying them for more than 35 years. Some adults weigh more than 500 pounds, and many obese teenagers are suffering from diabetes, the disease most frequently associated with obesity.

   But here's a really interesting fact - a group of Pima Indians living in Sierra Madre, Mexico, does not have a problem with obesity and its related diseases. Why not?

   The leading theory states that after many generations of living in the desert, often confronting famine, the most successful Pima were those with genes that helped them store as much fat as possible during times when food was available. Now those fat-storing genes work against them.

   Though both populations consume a similar number of calories each day, the Mexican Pima still live much like their ancestors did. They put in 23 hours of physical labor each week and eat a traditional diet that's very low in fat. The Arizona Pima live like most other modern Americans, eating a diet consisting of around 40 percent fat and engaging in physical activity for only two hours a week.

   The Pima apparently have a genetic predisposition to gain weight. And the environment in which they live - the environment in which most of us live - makes it nearly impossible for the Arizona Pima to maintain a normal, healthy body weight.

4. Environmental Factors

   Environmental and genetic factors are obviously closely intertwined. If you have a genetic predisposition toward obesity, then the modern American lifestyle and environment may make controlling weight more difficult.

   Fast food, long days sitting at a desk, and suburban neighborhoods that require cars all magnify hereditary factors such as metabolism and efficient fat storage.

   For those suffering from morbid obesity, anything less than a total change in environment usually results in failure to reach and maintain a healthy body weight.

5. Metabolism

   We used to think of weight gain or loss as only a function of calories ingested and then burned. Take in more calories than you burn, gain weight; burn more calories than you ingest, lose weight. But now we know the equation isn't that simple.

   Obesity researchers now talk about a theory called the "set point," a sort of thermostat in the brain that makes people resistant to either weight gain or loss. If you try to override the set point by drastically cutting your calorie intake, your brain responds by lowering metabolism and slowing activity. You then gain back any weight you lost.

6. Eating Disorders and Medical Conditions

   Weight loss surgery is not a cure for eating disorders. And there are medical conditions, such as hypothyroidism, that can also cause weight gain. That's why it's important that you work with your doctor to make sure you do not have a condition that should be treated with medication and counseling.

Health Threats of Morbid Obesity

Morbid obesity brings with it an increased risk for a shorter life expectancy. For individuals whose weight exceeds twice their ideal body weight (that's about 2-6% of the U.S. population), the risk of an early death is doubled compared to non-obese individuals. The risk of death from diabetes or heart attack is five to seven times greater. Even beyond the issue of obesity-related health conditions, weight gain alone can lead to a condition known as "end-stage" obesity where, for the most part, no treatment options are available. Yet an early death is not the only potential consequence. Social, psychological and economic effects of morbid obesity, however unfair, are real and can be especially devastating.

What Is Morbid Obesity?

Obesity becomes "morbid" when it reaches the point of significantly increasing the risk of one or more obesity-related health conditions or serious diseases (also known as co-morbidities) that result either in significant physical disability or even death. As you read about morbid obesity you may also see the term "clinically severe obesity" used. Both are descriptions of the same condition and can be used interchangeably. Morbid obesity is typically defined as being 100 lbs. or more over ideal body weight or having a Body Mass Index of 40 or higher. According to the National Institutes of Health Consensus Report, morbid obesity is a serious disease and must be treated as such. It is a chronic disease, meaning that its symptoms build slowly over an extended period of time.
