Weight-Loss Surgeries also Decrease Mortality
Over the previous two decades, gastric bypass surgery has is the surgery that surely decreases fatness and associated conditions. The surgery helps in loss of weight by reducing the size of the stomach with the help of a gastric band or by eradicating part of it.
Long-term studies have not only revealed the operation helps in weight loss but also helps in revival from diabetes, improvement in the cardiovascular system and a decrease in mortality.
The researchers at Stanford University studied the genetic data of 51 patients prior to undergo the weight loss operation. It was found that majority of them were women who were about 49 years old and with an average body mass index (BMI) of 44.3.
The outcome of the surgery was major weight loss, with the average patient loosing 71% of their excess weight.
Study co-author John M. Morton, MD, Chief of Bariatric Surgery at Stanford University Medical Center, said, "Obesity has an adverse effect on health, causes premature aging and reduces life expectancy".
The aim of this research was to observe the effect of surgical weight loss on telomere length in 51 persons who went through laparoscopic gastric bypass.
John M. Morton, MD, of Stanford University Medical Center in Stanford, Calif, told that telomeres are replications at the ending of each chromosome. The universal thought is that the shorter the telomere, the greater the increase in aging.
