I have been drinking just water for the past 3 days. But now my urine is dark yellow. Does anyone know why?

Question

Usually it's bright yellow to transparent. I read that the more water you drink, the lighter your urine is. But for some reason when I just went to the restroom (it's about 11:00 p.m here), my urine is darker than normal. Does anyone know why?

Answer 1

it probably just something you ate, it can have that affect. or if you are on medications it can do that.  

Answer 2

It could depend on the food you ate.  Or if you took some vitamins. I drink lots of water and when I take my vitamin it causes that a few hours later

Answer 3

You said that you have been drinking just water; do you mean you just stopped drinking say milk, beer, coke and still drink just the one glass of water on waking ?  Or did you stop drinking beer, milk and coke AND drank MORE WATER than you usually do ?

Try drinking 2 litres plus of water a day - 8 glasses of water.

Answer 4

To my understanding one of the reasons urine is lighter the more water you drink is becausee the water flushes out your kidneys and dilutes the urea (the stuff left over that your body does not need). What the others say is true. If what you ate recently included a lot of nutrients that were digested but not required they would be flushed out of your system. This would color your urine more.

This occurs more often with higher intakes of protein, if it smelled strongly then this is probably why.

It's really nothing to worry about. One's urine does become tea coloured when their kidneys are failing however this is probably not occurring as their would be multiple other symptoms.

Hope this helped =)
