Guest guest Posted January 13, 2011 Report Share Posted January 13, 2011 I read the article form the link: The control group - I am not clear as for how they were selected: Where they obese people who had lost wt in non-Sx mean or they were still obese with no intervention for the obesity? If I understand - the control group are obese with no intervention - if that's the case, then - no news under the sun: Obesity is still a risk for CA and CADs ect. as oppose to what the study want to claim that gastric bypass is the answer for CA as well as CADs and other co morbidities. But if the control group lost wt in non-surgical means then should we have EVERY obese client go for Sx? There is something very odd about this, at least from as far as my understanding of the study goes. Did I miss something? misunderstood?

The surgical treatment for obesity was already known to reduce heart disease and diabetes. The incidence of two of the most common tumors, breast and colon, were reduced by 85 percent and 70 percent respectively, said Dr. Nicolas Christou of McGill University in Toronto . Christou and his colleagues compared 1,035 patients who had bariatric surgery between 1986 and 2002 with 5,746 carefully matched obese patients who did not have the surgery; 81 percent of the surgery patients had a gastric bypass. Neither patients nor controls had previously been diagnosed with cancer. Those who underwent the surgery lost an average of 67 percent of their excess body weight. In the ensuing five years, the team observed 21 cancer cases in the surgery group (2 percent), compared with 487 cases (8.5 percent) in the control group, Christou said at a Washington meeting of the American Society of Metabolic & Bariatric Surgeons. Combined with earlier evidence, he said, " the data is pretty convincing " that weight loss reduces the incidence of cancer.
