Obesity is a major worldwide health problem. Obesity is an invitation for many diseases and is associated with significant morbidity and mortality.
The most widely accepted measure of Obesity is the Body Mass Index (BMI). This number is calculated by dividing a patient's mass (kg) by his/her height (m2). A normal BMI is considered in the range of 18.5-24.9 kg/m2.
Bariatric surgery is currently the only modality that provides a significant, sustained weight loss for morbidly obese patients, where other weight loss treatment, exercise and diet have failed to give result.
