Hiccups! in Post-op Gastric Bypass Posted January 3, 2017 · Report reply On 1/1/2017 at 7:32 PM, aswain said: I had Gastric Bypass on Weds and I am like you. Every time I start to get up I start to hiccup. It isn't because I'm drinking or eating too much.Its very painful because I just had the surgery. Same here. I had my surgery Thursday and I was immediately hiccuping, which was painful to say the least - since I was still on no liquids it was due to the gas in my system. My answer was to get up out of bed or the chair and go walk. Even if just to the end of the hall. It was persistent for the entire first night and then went away slowly over time. I used to make fun of my sister who hiccups when she eats finger foods. Well, I wasn't laughing Thursday night.
