Abstract
Obesity is the second leading cause of sudden deaths. Morbid obesity is defined as being 100 Ibs or more over the ideal body weight or having a Body Mass index (BMI) of 40 or greater. According to the American Society for Bariatric Surgery, morbid obesity is a serious disease and must be treated as such The incidence of obesity is steadily rising, and it has been estimated that 40% of the population will be obese by the year 2025 if the current trend continues An alarming indicator of the health crisis related to the epidemic of obesity is that 15% of children and adolescents are obese (BMI 95th percentile on the Centers for Disease Controls and Prevention standard charts), and over 20% are at risk (BMI 85 percentile) The major symptoms of obesity are excessive weight gain and the presence of large amounts of fatty tissue. Obesity can also give rise to several secondary conditions, including: arthritis and other orthopedic problems, ,adult-onset asthma, high cholesterol levels ,gallstones, high blood pressure, menstrual irregularities ,decreased fertility, and pregnancy complications, that can be incapacitating, emotional and social problems In recent years there has been renewed interest in the surgical treatment of morbid obesity hi concomitance with the epidemic of obesity, and application of the laparoscopic techniques to the field of bariatric surgery as well. Bariatric surgery proved effective in providing weight loss of large magnitude, correction of comorbidities and excellent short-term and long-term outcomes, decreasing overall mortality and providing a marked survival advantage Procedures of weight reduction are classified by the mechanism through which they achieve this reduction: malabsorptive, restrictive and combined malabsorptive and restrictive The types of bariatric procedures performed including Roux-en-Y gastric bypass, Laparoscopic Adjustable Gastric Banding (LAGB), laparoscopic sleeve gastrectomy (LSG) and bilio pancreatic bypass/duodenal switch (BPB/DS).
