I've noticed others have experienced these weird hiccup-y/burp things after surgery. Not uncomfortable but they are totally new to my body and I can't figure out if its my stomach spasming, gas being expelled or something else....

It could be a couple of different things. I burped A LOT the first few days after surgery. There was gas in me that needed to come out, and that's how it chose to come.

Now that I'm a few weeks out and eating real food, I still burp sometimes. It's usually an indicator that I'm eating too fast or too much. Sometimes it's a weird hiccup instead. I've gotten them far less since I slowed down my eating drastically.

Your new stomach is adjusting, and your body is adjusting to it. Gurgles, burps, and hiccups are all going to be normal.

I am 3 months post op as of July 7, 2016. I had hiccups during the first couple of months several times a day which was totally out of the ordinary for me. I have read that many people that have had the sleeve surgery have had this issue also. I still have hiccups on occasion but it is improved tremendously.
