Caffeine- elevated diuretic properties
I'm just curious if this happens to anyone else, or if this could be the symptom of a kidney problem...
For over 10 years now, whenever I drink soda, coffee, or tea with caffeine in it, for the next few days, I have to urinate very often. Sometimes it's so bad, I have to go literally every 5 minutes. I didn't realize that caffeine was the culprit until about 3 or 4 years ago. So I lived for years with having frequent, severe urges to go to the bathroom every few minutes (or when it wasn't so bad, every 45 minutes or so). I could rarely go on long car trips or sit through class without having to use the bathroom more than once.
Then a few years ago, I learned in my biology class that caffeine is a mild diuretic... So since then, I've stopped drinking caffeine, and I've improved a lot.
But does anyone know why my kidneys would react so severely to caffeine, when it's supposed to be a "mild" diuretic? Is this just something my body may be sensitive to, or do you think it's an indicator of a kidney problem?
