Weight-Loss Surgeries

Bariatric surgery   which is also known as weight loss surgery includes a variety of procedures performed to Obese people. In this, Weight loss is achieved by reducing the size of the Stomach with a gastric band or through removal of a portion of the stomach sleeve referred as Gastrectomy or Bilio-pancreatic  that may duodenal switch or by resecting and re- directing the small intestine to a small stomach pouch and it is termed as, Gastric pouch surgery. Bariatric surgical, includes procedures cause weight loss by restricting the amount of food the stomach can hold, causing  Mal-absorption of nutrients, or by a combination of both gastric restriction and Mal absorption. Bariatric procedures also often cause hormonal changes that may lead other complications as Hyperthyroidism and Insomnia. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery) which is also disadvantageous to mankind as it involves high energy radiations. However, research is emerging that suggests bariatric surgery could be appropriate for those with a BMI of 35 to 40 with no comorbidities or a BMI of 30 to 35 with significant comorbidities.
