Why would that be? I'm no biologist but I'm quite sure the CO2 won't make it all the way to the bladder, when drinking plain carbonated water.

A lot of carbonated water gives me gas, especially when not eating enough. But I am not sure it is an issue. People have various gas levels, it just goes in and out.

And this gas escapes through your urethra?

I always considered drinking a lot of sparkling water an antipattern. I think this is connected with microbiome or people who I knew and who abused the sparkling water. I'm refraining myself from such activities because of the same reason (gas) but I also am sick (SIBO or another inflammation, have to hit diet hard)
