Hello again. I was curious about your surgeon so I googled him and it seems he just started doing SADI, which is a single anastomisis Duodenal switch. It has similarities in the name to the traditional duodenal switch, so people sometimes make the mistake of thinking they are the same surgeries, but they aren't. Just to be sure, it is essential that you find out precisely which procedure was done. You can ask if he did a standard DS with two anastomoses, or a new, still experimental procedure called SIPS or SADI, which has a single anastomosis. You can read about this procedure before you talk with him.
This is important for your diet and supplements after surgery. The dietary recommendations are different for the new procedure. If he did a SADI, you have a shortened alimentary tract of 300 cm but ALL of it is common channel. This means you will not eat like the traditional DSers. For example, someone with SADI would not be able to freely eat fats, or as many calories. Your vitamin supplementation will be different as well. If he says he operated with a SADI procedure and not a traditional DS procedure, ask him why, and then ask for guidance about how to eat and what to eat. Also, ask him if you should watch out for bile reflux, which can't happen with a traditional DS.
It may be that he did a traditional DS, but with a new surgeon we don't know, it raises some questions. We are seeing confusion about these procedures and some people who weren't educated about the differences when they chose the surgery.
Come back here and tell us what you learned, because we will be thinking about you. We will help you regardless of what he says.
