I am a little disappointed in this recent post from CNN. It really is only giving a narrow view of the subject. It is suggesting that bariatric surgery does not affect the mortality rate, but when you actually read the article, it indicates it is a fairly narrow study. It only included about 850 older US male veterans over a period of 6.5 years. There is really no indication if there were other risks factors common to the group that would have skewed the results, nor is there any indication of the make-up of the control group. Significantly, the article says “older veterans” which would indicate we are talking about a narrow part of the society.
Personally I think it is rather irresponsible of CNN to essentially “dismiss” the potential benefits of bariatric surgery, especially for those that get the procedure earlier on in life (and are US male veterans).
