Does the caffeine in Coke Zero work as a diuretic?

Question

I've had a few over the last week or so and I have been peeing constantly. I suspect that I may be pregnant but I'm not sure if the increase in urinary frequency is related to the caffeine or the possible pregnancy.

Any thoughts?

Answer 1

I don't think caffeine works as a diuretic. If I'm not mistaken it tends to make you retain water.

Answer 2

The caffeine in coffee is a mild diuretic, but moderate consumption of coffee has no greater effect than that seen with plain water.
