Weight loss surgery may greatly reduce obese people’s risk of premature death, a new study says.
Nearly five years after surgery, the death rate was over one percent for the individuals who had weight loss surgery and four percent for those in the non-surgical group, according to researchers.
The study was led by Christina Persson from the University of Gothenburg in Sweden, who analyzed data from almost 49,000 obese people in Sweden. They were between 18 and 74 years of age.
Over 22,000 people had weight-loss surgery between 2000 and 2011. About 93 percent of the people in the surgery group had the procedure known as gastric bypass. The study compared them with approximately 26,000 people who did not have surgery.
According to the research, the overall death rate was reduced by 57 percent in the surgery group, compared to the non-surgery group. This number remained consistent after researchers adjusted for age and other previous diseases such as diabetes, cancer and heart disease.
Heart disease, cancer, suicide and accidents were the most common causes of death among those who did not have the surgery.
Cancer and heart disease accounted for most of the major difference in mortality rates between obese people who underwent weight-loss surgery and those who did not, says researchers.
Losing weight is not easy for anyone overweight so undergoing weight loss surgery should be recommended by doctors or health care providers. A death rate that is decreased by about 60 percent is amazing and I believe more obese people should consider having gastric bypass surgery to increase his or her survival.
According to the CDC, over one-third of adults in the U.S. are obese, so this is a very serious issue. There is no overnight success or magic pill that will make you lose weight so it really does take hard work and dedication.
The study was set to be presented Thursday at the European Obesity Summit. Findings presented at meetings are usually viewed as preliminary until they have been published in peer-reviewed journals.
