A member asked:

I have a appointment tomorrow for a checkup kidney, liver, bmi, bp etc. 8 hours fasting is preferred for that, so i can't drink water also or only can't eat?

A doctor has provided 1 answer

NPO: Actually, it is better to drink water. If you are dehydrated it may be harder to draw blood for tests. You should avoid eating though.
