Post Gastric Bypass Surgery Question

Okay, here is something that I haven't thought to ever ask my dietitian after my gastric bypass surgery .... Can I eat raw oysters? I used to enjoy them every once in a while before my weight loss surgery but have not had them in the 2 years since! I thought about it for the first time while I was in Key West enjoying fresh seafood and saw it on the menu. I am going to ask but until then if any one has had any experience with this please leave me a comment!!!
