Results of Weight Loss SurgeryAccording to recent research, data from a wide range of studies into the weight reduction effects of bariatric surgery indicates that the majority of patients experienced effective weight loss together with improvement in diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea. Details of Study Into Results of Bariatric SurgeriesHenry Buchwald, M.D., Ph.D., of the University of Minnesota, Minneapolis, and colleagues conducted a review of 136 studies published between 1990 and 2003, which included 22,094 patients who underwent bariatric surgery, to determine the impact of bariatric surgery on weight loss, operative mortality outcome, and four obesity related disorders (diabetes, hyperlipidemia, hypertension and obstructive sleep apnea). The bariatric surgery procedures included gastric banding, gastric bypass, gastroplasty, biliopancreatic diversion or duodenal switch, and others (such as jejunoileal bypass, a bypass of a section of the small intestine). Nineteen percent of patients were men and 72.6 percent were women, with an average age of 39 years. The average body mass index for 16,944 patients was 46.9 before surgery. Average Post-Operative Weight ReductionThe researchers found that the average percentage of excess weight loss was:
Death Rates For Bariatric SurgeryDeath due to surgery within 30 days of the procedure was 0.1 percent for purely restrictive procedures (gastric banding and gastroplasty), 0.5 percent for gastric bypass, and 1.1 percent for biliopancreatic diversion or duodenal switch. Effect of Surgery on Obesity Related Health ConditionsDiabetes was completely resolved in 76.8 percent and resolved or improved in 86 percent of patients. Hyperlipidemia (i.e., elevated levels of cholesterol and triglycerides in the blood), improved in 70 percent or more of patients. Hypertension was resolved in 61.7 percent, and resolved or improved in 78.5 percent of patients. Obstructive sleep apnea was resolved or improved in 83.6 percent of patients. Incidence of ObesityResearch indicates that an estimated 1.7 billion people worldwide are overweight or obese. "Overweight" is defined as having a body mass index (BMI) of 25 or higher, while "obesity" is defined as a BMI of 30 or higher. "Morbid obesity" is BMI 40 or higher, and "Malignant obesity" is BMI 50+. Health Consequences of ObesityBeing obese is associated with a greater risk for type 2 diabetes, hypertension, heart disease, stroke and asthma. The loss of life expectancy due to morbid obesity is significant: in comparison with a normal-weight individual, a 25-year-old morbidly obese man has a 22 percent reduction in expected remaining lifespan, representing an approximately loss of 12 years of life. For treating obesity long term, diet therapy has been found to be relatively ineffective. ------------------------------------------------ Gastric Bypass Bariatric Information |
