"For certain patients there are reasons why if they don't have the operation, lose a significant amount of weight, fix their diabetes, improve their cardiac condition, or improve their lung condition.. these patients may reasonably expect to die anywhere in the next 1, 2, 5, 10 years."
Two studies published in the New England Journal of Medicine found a significant long term benefit to bariatric surgery for the morbidly obese: a reduced risk of death. The first study by the University of Utah examined gastric bypass surgery according to data collected on nearly 16,000 severely obese people, half of which had undergone the surgery between 1984 and 2002. The results of the study found surgery patients were 40% less likely to die from any cause during the 7 year follow period. Additionally, patients were 92% less likely to die from diabetes, 59% less likely to die from coronary artery disease, and 60% less likely to die from cancer.
The second study by Gothenburg University in Sweden, observed 4,000 obese volunteers with half undergoing a type of bariatric surgery and the other half undergoing conventional obesity treatment. Ten years following the treatment, the bariatric surgery group had lost more weight and had a 24% reduced risk of death compared to the conventional treatment group. For patients suffering from morbid obesity, choosing to have surgery should be a careful consideration but one that should not be overlooked.
