There is plenty of data on RNY around. It has a longer history than any other wt loss surgery, hence more post ops, and more health data. Supplementation and tracking nutrient levels with labs is mandatory to prevent many potential issued due to deficiencies. My surgeon's nurse waws asked this same question about life longevity on Tuesday night. She stated that data indicates life span IS INCREASED with RNY post ops if surgery is done before age 60. After 60, data does not indicate a prolonged life, nor a shortened life. Better health is a common result from lower wt, as long as you follow the surgical protocol, especially about protein intake, hydration, vitamins and calcium citrate. BTW your calcium citrate is absorbed best with vitamin D levels of 80-90, which most likely will only be attained by using the 50K IU dry D3--multiple days each week, but most likely not daily. Why not attend a seminar by a couple of surgeons and pose this question to them? Higher D levels have shown to decrease chances getting several cancers by 50% as another example of health benefits of following protocol. DAVE
