Anne Marie, First of all, no it is not normal to be constipated for 1-2 weeks. Second of all, if you cannot keep water down, you need to see your surgeon IMMEDIATELY. It would explain for the most part your constipation, you are probably dehydrated. You also probably have a stricture, which needs to be stretched through a simple procedure called endoscopy. It's normal to vomit occasionally during the first 2-3 months post-op, because you are re-learning how much you can eat, how to chew things really thoroughly, and you will overdo at times until you get used to your new tummy. But vomiting everytime you eat is indicative of a stricture, especially if you can't even keep liquids down. Call your doctor immediately and tell him you will not wait. Good luck.
