Authors: Eldo E. Frezza, MD, MBA, FACS, Amber Moreland, MSII


Morbid obesity is one of the most common causes of morbidity and mortality in the United States. In the next 20 years, 40% of the population will be obese with a body mass index (BMI) greater than 30. Operations for morbid obesity (BMI >35), such as Roux-en-Y gastric bypass (RYGBP), are becoming more popular.
