A new JAMA study suggests that being overweight can add to the life span instead of decreasing it. Dr. Atul Madan says that this study contradicts years of research on the life-threatening cost of obesity, and that patients can still consider LAP-BAND® surgery as a means of adding to their life expectancy.
Los Angeles, California (PRWEB) March 18, 2013
A study published this year by the Journal of the American Medical Association (JAMA) in February of 2013 seems to suggest that people should not worry about adding on a few pounds. This sparked a news wave intent on affirming the idea that a little bit of obesity can be good, rather than bad. While it is popular to overturn years of research by the effects of one popular study, bariatric surgeon Dr. Madan says that this one-study approach can be dangerous. Many studies have shown clear evidence that obesity reduces life expectancy, especially when linked with serious health issues such as diabetes. Along with Dr. Scott Atlas of Forbes magazine in February of 2013, Dr. Madan discourages the idea that being overweight is good for health.
What is true about the JAMA study, says Dr. Madan, is that BMI is not always an accurate predictor of being overweight or even obese. However, he adds, the meta-analysis study was done by researching compiled data of other studies, rather than a controlled or double-blind trial conducted independently on patients. Meta-analysis studies are useful as far as seeing trends, but can be subject to biases of the researchers. Also, the study specifically notes that only one BMI associated with being overweight (between 25 to 29) showed a slight improvement in numbers over those of normal weight.
Out of the 97 studies analyzed, the research was conclusive that those with grades 2 and 3 obesity (with BMI exceeding 35) were certainly subject to less life expectancy. Being overweight, commented Dr. Madan, is quite different from being obese. In any case, the research only showed a 6% improvement for those with BMI's between 25 and 30 - hardly more than a normal margin of error. Other possibilities were posed by writers in the same JAMA journal, including the idea that extra weight encourages a more aggressive treatment of high cholesterol and other risk factors, and that BMI does not always indicate levels of fat, or sugar in the bloodstream.
One difference between being 'overweight' and 'obese' is the lack of co-morbidities, or health issues that seriously affect life expectancy. One of the reasons why the lap-band procedure, or gastric banding, is approved by the Food and Drug Administration is because obesity brings with it a host of factors that crowd out healthy living. Forbes writer, Dr. Scott Atlas, quotes from a long list of health issues linked strongly with obesity: heart disease, stroke, renal disease, gallbladder cancer, hip arthritis, and infertility. Many studies, he says, have indicated that obesity can reduce length of life between 8 to 10 years. "According to the OECD, for every 15 kilograms of excess weight, the risk of death increases by about 30%." In fact, said one Harvard study, four years could be added on average for those who kicked the obesity habit by 2020.
Another Harvard Gazette article pointed out the strong link between obesity and diabetes, saying that a BMI of 25 reduces the risk of contracting diabetes by 90%. Dr. Madan agrees with nutrition Associate Professor of the Beth Israel Deaconess Medical Center: "We know exactly what to do to treat this disease: cut calories.” The problem is that cutting calories doesn't produce results quickly enough to make health changes necessary for those whose BMI's have reached dangerous levels. Also, many candidates for lap band surgery, with a BMI of 35 or over, have tried many diet and exercise programs without noticeable results. Dr. Madan says that lap band is one of the best methods for diet restriction available, allowing patients to quickly lose weight, which serves as an inspiration to further lifestyle change.
Dr. Madan has written 175 articles, and was the first in Memphis to perform a laparoscopic gastric bypass. To date, he has performed over, and was first to offer an incision-less treatment for post-operative weight gain. As the former Chief of Laparoendoscopic and Bariatric Surgery Division at the University of Miami, Dr. Atul Madan may well be considered an expert in his field. Dr. Madan won the 2007 SAGES Young Investigator Award, was honored by the American Medical Association Physican's Recognition Award, among others. Dr. Madan's patient reviews are consistently high, and he received the 2011 and 2012 Patients' Choice Award.
