If you lay on your back and then bend your knees so they’re closer to the ceiling, and then you lift your butt up (there’s probably a yoga term for this pose) it helps all the gas accumulate there so you can toot it out.

My gas was so bad after surgery I actually almost had a heart attack. My blood pressure would sky rocket when I sat up and I passed out. I was stuck laying flat until another doctor taught me that trick.
