Do i qualify for weight loss surgeryExperience matters - Northwest Weight Loss Surgery has the most experience in offered Weight Loss Surgery to people with a BMI of 30 to 35. Dr. Michaelson was the only weight loss surgeon in the country invited to speak to the FDA regarding criteria changes.  

"As a surgeon, I see patients every day who have been obese for years and have tried several diet and exercise programs without success," Dr. Michaelson said in the press release. "These patients frequently feel judged by their weight, as obesity is often viewed as a lack of will power, which it is not. Obesity is a disease, which requires medical treatment, but unfortunately, diet and exercise alone do not work for everyone."

The guidelines established by the FDA (U.S. Food and Drug Administration) for weight loss surgery are as follows:

Since obese people are clearly at an increased risk for multiple, potentially life threatening medical conditions, there is universal agreement that substantial, long-lasting weight loss should be the treatment goal for obesity. We know that the majority of obesity related medical conditions will resolve or significantly improve with substantial, sustained weight loss. This can be most effectively treated through surgery, including gastric sleeve or lap band, and followed through with a long-term support system. 

A clinical description of the degree of obesity helps determine if a person is a candidate for weight loss surgery. Obesity is defined by a Body Mass Index (BMI) greater than 30. Body mass index is calculated by a person's weight in kilograms divided by their height in meters squared (BMI = weight/height2 or kg/m2). This can also be calculated by a person's weight in pounds divided by their height in inches squared multiplied by a correction factor (lbs/inches2 X 703). 

The FDA guidelines state that a person with a BMI of 35 to 40 with weight related health problems OR a person with a BMI greater than 40 is a candidate for surgical treatment for obesity. Typically insurance plans that allow for weight loss surgery  will follow these guidelines.

18 - 24 Normal Weight
25 - 30 Overweight
30 - 35 Obesity, Class 1
35 - 40 Severe Obesity, Class 2
40+ Morbid Obesity, Class 3

The BMI is a formula that uses weight and height to estimate health risk. If your BMI is between 18 and 24.9, you're considered in a healthy weight range for your height. If your BMI is between 25 and 29.9, you're considered overweight. And, if the figure is 30 or greater, you're considered obese. The following table shows examples of healthy weight, overweight and obese weight ranges for several heights. 

5 feet 2 inches
(62 inches)
101 to 136 pounds 137 to 163 pounds 164 pounds or more
5 feet 6 inches
(66 inches)
115 to 154 pounds 155 to 185 pounds 186 pounds or more
5 feet 10 inches
(70 inches)
129 to 173 pounds 174 to 208 pounds 209 pounds or more
6 feet 2 inches
(74 inches)
144 to 194 pounds 195 to 233 pounds 234 pounds or more

A threefold approach can help determine whether you need to lose weight for medical reasons. These include body mass index, waist measurement and personal medical history.

Waist Measurement

If you carry most of your fat around your waist or upper body, you may be referred to as apple-shaped. If you carry most of your fat around your hips and thighs or lower body, you may be referred to as pear-shaped. When it comes to your health, it's better to have the shape of a pear than the shape of an apple. If you have an apple shape - a potbelly or spare tire - you carry more fat in and around your abdominal organs. Abdominal fat increases your risk of many of the serious conditions associated with obesity. Women's waist circumference measurements should be less than 35 inches. Men's should be less than 40 inches. These are rough cutoffs, but in general, the smaller the waist measurement the better.

Medical History

You may benefit from weight loss surgery if you have other health conditions such as high blood pressure and diabetes. Also, if you have a family history of obesity, cardiovascular disease, diabetes, high blood pressure or sleep apnea, you may have an increased risk of developing weight-related complications.

Evaluation Process at Our Bariatric Clinic in Everett WA

An experienced team of medical professionals including a doctor, dietician, bariatric surgeon and psychologist will evaluate your overall health and determine whether weight loss surgery is a good option for you. They will factor in your current BMI along with eating habits, exercise regimen, stress levels and history of diet attempts. In addition, we will verify that you don't have other other health conditions that could threaten overall health during your weight loss journey, such as blood clots, heart disease, kidney issues or liver disease. You will also need to undergo lab testing, a full physical exam and a psychological exam. 

A person with a BMI of 30 or greater is considered obese. Weight loss surgeries, such as gastric sleeve or gastric bypass, will considerably improve health and reduce the risk of obesity-related illnesses. 

The decision to have surgical treatment for weight loss requires a careful assessment of the risks and benefits in each individual case. Occasionally, there are people who would benefit from weight loss surgery despite the fact that they do not strictly meet the NIH guidelines; ideally, they are well-informed, motivated, and have acceptable operative risks. They should be able to participate in treatment and long term follow-up.

We rarely decline a person for surgery. Some people, however, with significant psychological or physical problems are not candidates for surgery. Some psychological conditions may jeopardize informed consent and cooperation with long-term follow up. The preoperative psychological evaluation serves the purpose of helping people plan for the emotional changes that occur with massive weight loss. Occasionally, the evaluation will identify untreated depression; in that case we help the person get their depression treated prior to surgery.

Becoming overweight doesn't happen overnight. It happens over time when the energy we take in by eating is not balanced with the energy we burn from physical activity.
