Had gastro direhha for 24 hours, now when i go to the toilet to urine it's dark like apple juice, i'm drinking a fair bit of water but still dark ?

? hepatitis: Many causes but also make sure that your liver is ok. When the urine darkens you could have too much bilirubin from your liver/gallbladder in your system. May also want to be checked for hepatitis a, etc. Good luck.

Dehydration: Diarrhea makes your body lose more water than you realize, and you're probably still dehydrated. Just for normal function, drinking at least 8, 8-ounce glasses of water is recommended. With your diarrhea, you need much more than that to catch up! normal urine is a pale yellow color. If no better in a couple of days with rehydration, see your doctor & check urine for bilirubin & other.
