According to a recent study, obese men who have weight loss surgery did not have increased survival rates, at least during the first seven years after surgery.
The prior studies have stated that people who have weight loss surgery have higher survival rates after the first two to ten years after surgery. This new study was conducted mostly on old male veterans, and showed different results. It seems that the gains after the surgery are not the same for everyone, and that the benefits in older men do not come as soon as in the case of the young ones.
Studies on Men
The previous studies were conducted mostly on young women. Matthew Maciejewski of the Veterans Affairs Medical Center in Durham, N.C, stated that all the previous studies were conducted on very different patients, and that the methods used were less rigorous. In the past, all the previous studies were associated with reduced mortality, but it seems that things are different. In some of the cases, the organs of the patients were too damaged by the obesity, so that they could not recover even after the weight loss.
Dr. Philip Schauer of Cleveland Clinic’s Bariatric and Metabolic Institute, stated that in some of the cases, it might be too late for these people to undergo treatment. He advised that people should not consider too much getting the surgery, and that they should do it if they have the chance. Prior to this point, all evidence indicated the fact that obesity surgery has numerous health benefits. More than 200,000 such surgeries are performed each year, and the operations cost around $5 billion yearly.
Some of the benefits of the obesity surgery improves the quality of life, causes weight loss, and reduces diabetes symptoms, sleep apnea and blood pressure. These are the main reasons why people undergo the obesity surgery. However, Maciejewski said that he and his colleagues want to see if the effects of the surgery can be seen in the later years as well, after 10 or even more years.
The benefits of surgery
The researchers stated that the surgeries do have some benefits, such as the improvement of quality of life. In comparison to the group of patients who did not have surgery, the ones who had it, lived longer. However, the researchers stated that it cannot be proven that the reason why they lived longer was because of the surgery. It could have been because they were healthier in the first place. The patients had bypass surgery between 2000 and 2006. The bypass surgery makes the stomach smaller, and thus less food enters the small intestine.
Because of that, the body absorbs fewer calories, and the patients start to lose weight. 11 patients died in the first month after surgery, and one of the reasons for that could be that men handle the surgery much more difficult than the women. Men collect all the fat in the belly, and because of that, the doctors might have a more difficult time performing the surgery.
