What is BMI

BMI is the most widely used measurement for obesity. The BMI approximates body mass using a mathematical ratio of weight and height [(weight in kg ÷ height in meters2) or (weight in pounds ÷ height in inches2 x 703)].
A BMI of 30 or more is regarded by most health agencies as the threshold for obesity. A BMI of 40 or more generally qualifies as morbid obesity. However, note that BMI measurements in body-builders and athletes may not be accurate determinants of obesity because the BMI does not distinguish between muscle and fat.

Federal Guidelines for Healthy Weight

  • Underweight. Your BMI is less than 18.5.
  • Ideal Weight for Your Height. Your BMI is between 18.5 and 24.9.
  • Overweight. Your BMI is between 25 and 29.9.
  • Obese. Your BMI is 30 or greater.
Important Lap-Band® System Safety Information

The Lap-Band System is indicated for weight reduction for patients with obesity, with a Body Mass Index (BMI) of at least 40 kg/m2 or a BMI of at least 30 kg/m2 with one or more obesity-related comorbid conditions. It is indicated for use only in adult patients who have failed more conservative weight reduction alternatives, such as supervised diet, exercise and behavior modification programs. Patients who elect to have this surgery must make the commitment to accept significant changes in their eating habits for the rest of their lives.

The Lap-Band System is not recommended for non-adult patients, patients with conditions that may make them poor surgical candidates or increase the risk of poor results, who are unwilling or unable to comply with the required dietary restrictions, or who currently are or may be pregnant.

The Lap-Band System is a long-term implant. Explant and replacement surgery may be required. Patients who become pregnant or severely ill, or who require more extensive nutrition may require deflation of their bands. Anti-inflammatory agents, such as aspirin, should be used with caution and may contribute to an increased risk of band erosion.

Placement of the Lap-Band System is major surgery and, as with any surgery, death can occur. Possible complications include the risks associated with the medications and methods used during surgery, the risks associated with any surgical procedure, and the patient’s ability to tolerate a foreign object implanted in the body. Most common related adverse events include: Band slippage, pouch dilation, stoma obstruction, gastroesophageal reflux, esophageal dilation, cholelithiasis, incisional infection, abdominal pain, gastroenteritis, or nausea and vomiting may occur. Reoperation may be required. Rapid weight loss may result in complications that may require additional surgery. Deflation of the band may alleviate excessively rapid weight loss or esophageal dilation.
