OP’s doctor was concerned about them being properly hydrated so I would think that the diuretic effects of caffeine are an issue. Maybe under normal circumstances it isn’t a huge problem but if you are experiencing medical issues that require a lot of hydration then that isn’t doing you any favors. You’ll have to drink more to get the same hydration that you would from water with no diuretic effect. When you aren’t drinking 80 oz and your doctor says you need to do that right now, that’s gonna be a lot of drinking and it’s probably going to be a hard adjustment. So have a pop if you want but that really shouldn’t be the main source of hydration.

schmidtster@lemmy.world 11 months agoI thought they figured out caffeine was a false flag, it is a diuretic, but the amount of water consumed with drinking caffeine far offsets what you lose.

Yes, soda is more hydrating than diuretic, but you’ve gotta look at the practical example rather than the ear data. The amount of caffeine in soda would become a problem if you tried to stay properly hydrated by drinking soda. You’re only supposed to have ~400mg of caffeine in a day, and a can of soda has ~30-50mg on average in 355ml of liquid. 10 cans of soda might be almost enough to get the water you’re supposed to drink, but you’d be pretty much at your daily caffeine limit; any more and you’d be in danger of heart issues, doubly so because of the dehydration, not to mention all the sugar and other crap in 10+ cans of soda…
Obviously these numbers vary by person, but not so much that the caffeine content isn’t a concern for people who drink soda exclusively.
