Body mass index (BMI) is the medical standard for measuring the presence and degree of obesity, and is a ratio between an individual's height and weight. It is calculated by dividing one's weight in kilograms by the square of one's height in meters (kg/m2). Learn more about BMI.
Severely obese patients have a BMI of 35 to 39.9, and suffer from one or more obesity-related diseases, such as high blood pressure, high cholesterol, sleep apnea, or Type 2 diabetes. Morbidly obese patients have a BMI of 40 or greater. This means they are 100 pounds or more above their ideal body weight, and are at extremely high risk for developing one or more obesity-related diseases. Learn more about obesity.

Drexel bariatric surgeons offer two weight-loss surgery options (i.e., Roux-en-Y Gastric Bypass and Vertical Sleeve Gastrectomy. These procedures are performed using the laparoscopic or open technique, depending on the patient's individual needs.
Roux-en-Y Gastric Bypass
Roux-en-Y gastric bypass surgery provides a combination of restriction and malabsorption. During the procedure the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel full sooner and eat less food; bypassing a portion of the small intestine means the patient's body absorbs fewer calories. This is still the most common type of weight-loss surgery performed in the United States.
Weight loss is realized through the combination of limited portion sizes, reduced caloric intake, and altered digestion.
Vertical Sleeve Gastrectomy
Vertical sleeve gastrectomy is a restrictive bariatric surgery procedure that reduces the size of the stomach (by approximately 85%), without bypassing the intestines or causing any gastrointestinal malabsorption. During this procedure, the surgeon creates a small sleeve-shaped stomach, which will typically hold between 50 to 150 ml (about the size of a banana). The remaining portion of the stomach is removed. The vertical sleeve gastrectomy is a restrictive procedure, which is usually indicated as a safe option for individuals with a BMI greater than 55, but is equally effective for morbidly obese patients with a BMI lower than 55.
Weight loss occurs because it reduces the amount of food – and calories – that can be eaten, and provides a prolonged sense of fullness after eating.
