Should I have surgery for obesity?

Posted by The RichMan Monday 10 August 2009

Introduction:

If you are obese and lifestyle changes and taking medicines have not helped you lose enough weight, surgery may be an option. However, all weight loss surgeries have risks, and it is important for you and your health professional to discuss the risks and benefits and decide what is best for your situation. Consider the following when making your decision:

* Although guidelines vary, surgery is generally considered when your body mass index (BMI) is 40 or higher and you also have a life-threatening or disabling condition related to your weight. The following conditions may also be required, or are at least considered:
o You have been obese for at least 5 years.
o You do not abuse alcohol.
o You do not have untreated depression or another major psychiatric disorder.
o You are between 18 and 65 years of age.

* Depending on the type of surgery, most people lose from about 30% to 80% of their excess weight (the weight above what is considered healthy).

* Some of the weight lost may be regained.

* Some types of surgery may put you at risk for nutritional deficiencies.

* People who are obese have a higher risk of complications from surgery.


Medical Information:

What is obesity?

Obesity is a complex disease in which having too much body fat puts you at risk for health problems. Obesity is measured by body mass index (BMI). A BMI of 30 or more is considered obese.
What are the risks of obesity?

Being obese increases your risk for many health problems, including heart disease, high blood pressure, type 2 diabetes, and joint problems. Losing even 5% to 10% of your body weight may help reduce your risk. This would mean, for example, losing 25lb if you weigh 250lb. 1 Weight loss reduces blood pressure and cholesterol levels and helps reduce blood sugar levels in people who have type 2 diabetes.

How is the surgery done?

Surgery for obesity can be done by making a large incision in the abdomen (an open procedure) or by making several small incisions and using small instruments and a camera to guide the surgery (laparoscopic method). Laparoscopic surgery for obesity reduces recovery time and postsurgery complications.

Your Information:

Your choices are:
* Have surgery.
* Do not have surgery and instead use medicine and lifestyle changes.
* Do not have surgery and make only lifestyle changes.

The decision about whether to have surgery takes into account your personal feelings and the medical facts.

Deciding about surgery for obesity

General reasons to have surgery:
* Depending on the type of surgery, you may lose from about 30% to 80% of your excess weight (the weight above what is considered healthy).
* You have a body mass index (BMI) of 40 or higher or a BMI of 35 or higher and a health problem, such as diabetes.
* You have tried diet, activity, and medicines and have lost little or no weight.
* Losing weight will reduce related health problems such as high blood pressure, type 2 diabetes, high cholesterol, coronary artery disease, and sleep apnea.

Are there other reasons that you might want to have surgery?

General reasons not to have surgery:
* You have an ongoing problem with alcohol.
* You have untreated depression or another major psychiatric disorder.
* You are younger than 18 or older than 65.
* Risks common to all surgery for weight loss include infection of the abdominal cavity, a blood clot in the lung (pulmonary embolism), gallstones, and nutritional deficiencies that can result in anemia or osteoporosis.
* There is a risk of death. Fewer than 3 in 200 (1.5%) die after surgery for weight loss.
* Surgery is expensive if insurance does not cover it.
* You will have to make big changes in how you eat, including eating different foods than you are used to and having smaller portion sizes.
* Rapid weight loss may cause an excess of flabby skin, which may require more surgery to remove it.
