ELI5: What determines whether gas comes out your mouth or your butt?
gpt
It depends on where the air is released or generated in the metabolic process. If you drink a carbonated beverage, there's a lot of gas dissolved in the soda so you're more likely to burp it out. Other foods create gas as a metabolic by-product and that usually stays trapped in the digestive tract to produce flatulence. If gas is produced in the stomach, you are likely to belch it and if it is produced in the intestines, you would fart it.
