Body Mass Index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. Please see related content at right for link to calculate your BMI.
Obesity is defined as a person who has a Body Mass Index (BMI) greater than or equal to 30. Obesity is divided into three classifications according to the persons BMI:
- Class I - BMI 30.0 to 34.9.
- Class II - BMI 35.0 to 39.9.
- Class III - BMI 40 and above.
Obesity is a chronic condition that develops from an interaction of genetics and the environment. Because of these multiple factors, weight loss surgery is not considered to be the first or only treatment for obesity. Treatment requires comprehensive medical and behavioral management. Weight loss and weight control programs use multiple interventions and strategies, including individualized dietary therapy, physical activity, life-style/behavior therapy and surgery. Weight loss surgery is reserved for a limited number of adults whose obesity is:
- Class II and efforts at combined therapies of diet, exercise, and behavioral management have failed and other medical condition(s) existing simultaneously and usually independently of the severe obesity (co-morbidities).
- Class III and efforts at combined therapies of diet, exercise, and behavioral management have failed and are at high risk for obesity-associated co-morbidity or death (mortality).
Weight loss surgery is intended to provide weight loss sufficient to reduce mortality risk and improve medical conditions when less invasive methods of weight loss have failed.
Weight loss surgery is not an alternative to a diet and exercise management program. An integrated program such as HealthPartners’ Weight Loss Surgery phone course must be in place to provide guidance on diet, physical activity, and behavioral and social support both prior to and after the surgery. Weight loss surgery is a weight loss intervention option for well-informed, motivated individuals with an acceptable operative risk.
Descriptions of bariatric surgery procedures:
Roux-en-Y Gastric Bypass (RYGBP) 43644, 43846
The RYGBP achieves weight loss by gastric restriction and malabsorption. Reduction of the stomach to a small gastric pouch (30 cc) results in feelings of satiety following even small meals. This small pouch is connected to a segment of the jejunum, bypassing the duodenum and very proximal small intestine, thereby reducing absorption. RYGBP procedures can be open or laparoscopic.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS) 43845
BPD achieves weight loss by gastric restriction and malabsorption. The stomach is partially resected, but the remaining capacity is generous compared to that achieved with RYGBP. As such, members eat relatively normal-sized meals and do not need to restrict intake radically, since the most proximal areas of the small intestine (i.e., the duodenum and jejunum) are bypassed, and substantial malabsorption occurs. The partial BPD with duodenal switch is a variant of the BPD procedure. It involves resection of the greater curvature of the stomach, preservation of the pyloric sphincter, and transection of the duodenum above the ampulla of Vater with a duodeno-ileal anastamosis and a lower ileo-ileal anastamosis. BPD/DS procedures can be open or laparoscopic.
Adjustable Gastric Banding (AGB) 43770-43774; 43886-43888; S2083
AGB achieves weight loss by gastric restriction only. A band creating a gastric pouch with a capacity of approximately 15 to 30 cc’s encircles the uppermost portion of the stomach. The band is an inflatable doughnut-shaped balloon, the diameter of which can be adjusted in the clinic by adding or removing saline via a port that is positioned beneath the skin. The bands are adjustable, allowing the size of the gastric outlet to be modified as needed, depending on the rate of a member’s weight loss. ABG procedures are laparoscopic only.
Sleeve Gastrectomy 43775
Sleeve gastrectomy is a 70%-80% greater curvature gastrectomy (sleeve resection of the stomach) with continuity of the gastric lesser curve being maintained while simultaneously reducing stomach volume. It may be the first step in a two-stage procedure when performing RYGBP. Sleeve gastrectomy procedures can be open or laparoscopic.
Vertical Gastric Banding (VGB) 43842
VBG achieves weight loss by gastric restriction only. The upper part of the stomach is stapled, creating a narrow gastric inlet or pouch that remains connected with the remainder of the stomach. In addition, a non-adjustable band is placed around this new inlet in an attempt to prevent future enlargement of the stoma (opening). As a result, members experience a sense of fullness after eating small meals. Weight loss from this procedure results entirely from eating less.
Transoral gastroplasty (TG) is a minimally invasive, incisionless, reversible weight-loss procedure in which the stomach size is restricted with staples or sutures by using endoscopic surgical tools guided through the mouth and esophagus into the stomach. Two examples of this procedure that are proposed for revisions of standard weight loss surgery are Stomaphyx and the ROSE procedure (restorative obesity surgery – endoluminal).
