Bariatric Surgery For Treating Obesity

Obesity is a growing health problem in the United States

. As the incidence of obesity increases, so do the health problems associated with it. Obesity leads to 30 to 50 percent more chronic medical problems than heavy smoking or drinking. It contributes to coronary artery disease, cancer (breast, cervix, colon, esophagus, kidneys, pancreas, prostate and uterus), diabetes, hypertension, pancreatitis, gall bladder problems, gout, infertility, liver problems and stroke. When traditional methods such as diet and exercise fail, some obese individuals may resort to bariatric (weight loss) surgery. Presently, bariatric surgery is experiencing explosive growth fueled by the increasing obesity in the United States. Bariatric surgery offers health benefits to many morbidly obese individuals. The National Institutes of Health guideline for bariatric surgery requires a BMI of at least 40 or a BMI of at least 35, together with weight related problems such as diabetes and heart disease.

Gastric bypass is the most common type of bariatric surgery, with Roux-en-Y being the most commonly performed gastric bypass surgery. Roux-en-Y gastric bypass (RYGBP) reduces stomach size so that patients feel full after eating small amounts of food. The RYGBP creates a small stomach pouch which bypasses part of the small intestine called the duodenum and attaches to the middle of the small intestine. Bypassing the duodenum causes fewer calories to be absorbed, but also greatly decreases the amount of iron and calcium absorbed, so dietary supplements must be taken after surgery for the patients lifetime. On average, patients shed 63% of their excess weight with gastric bypass surgery during the first 12 months. Obesity Surgery Los Angeles surgeons perform Roux-en-Y bypass surgery on an open or laparoscopic basis. Laparoscopy allows surgeons to operate using small incisions that cause less trauma to the patients during surgery and a shorter hospital stay. While laparoscopic gastric bypass surgery has become more common than the open surgery, not all bariatric surgery patients are candidates for laparoscopic surgery.

Laparoscopic adjustable gastric banding (LAGB) is the second most popular type of bariatric surgery. In this surgery, a silicone band encircles the upper position of the stomach reducing stomach size. Similar to gastric bypass, patients eat less because they feel full more quickly due to their reduced stomach size. The band is attached to a saline-filled balloon that can be adjusted to further reduce or increase the size of the stomach. On average, patients loose 40% of their excess weight at 12 months with gastric banding.

Two other types of bariatric surgeries are Vertical Sleeve Gastrectomy and Biliopancreatic Diversion with duodenal switch. Vertical Sleeve Gastrectomy removes a portion of the stomach thus reducing stomach size and decreasing the amount of food a patient can consume. In some cases Sleeve Gastrectomy Surgery Los Angeles patients have bypass surgery following the sleeve gastrectomy procedure to increase weight loss. Biliopancreatic diversion with duodenal switch removes a portion of the stomach. This smaller stomach pouch bypasses the duodenum and is then connected to the small intestine. On average, patients loose 63-75% of their excess weight within 12 months of surgery.
