Hi Diane,
Thanks for the warm welcome. I am happy to answer any questions members have about both the sleeve and the RNY bypass.
To answer your question, the feel of restriction and the sensation of being full differs greatly between the two procedures. My sleeve was 8 years out prior to revision and I still had plenty of restriction. I still ate very small portions although the amount had increased from the 2 to 3 oz to possibly 5 or 6 oz. No more or I would get sick to my stomach. The RNY has much less restriction. I honestly haven't experienced it much-but to be honest- I am not eating dense protein yet and I have been promised I will feel it then. That remains to be seen.
Like I mentioned, the sensation of being full is very different as well. I could easily feel when I met my limit. My nose would start to run if I really pushed the limit. No doubt it was time to stop eating. The bypass makes you be mindful about what you are eating to ensure you don't eat too much. The signs are more subtle. I have identified that I first start to have gas in the form of a quiet belch to know I am full. If I miss that cue I will start to hiccup. One bite too much and you know it by the slimy foamies that ensue right after that. You will also feel a slight pressure under your sternum when you have pushed your max.
I am only 4 weeks post op so learning about my newborn tummy still. Things may change over time but this is what I have noticed thus far.
