I had the loop DS in June 2016. I received all the paperwork for the traditional DS. After doing some research I know the difference between between the 2 but to answer your question I will draw on my own experience. My common channel is 250 most DS are between 100 and 150. I guess I do not mal absorb as much with a longer channel. I still take 2 multi Vitamins 4 Calcium a day. I just got my 6 week labs back and need some Vitamin D and a little Iron. My weight has dropped averaging a lb or more a day. I know there is no long term data on this surgery but I feel good about it and hope I am right that I will not have to be on such a rigiorous Vitamin regimen or other bathroom issues sometimes associated with the traditional DS. As far as food goes I'm not hungry but when I am I try and get Protein first and anything else after.
