Dehydration

How do you know if you are dehydrated, what are the signs to know when you need to go to hospital ? I'm alright now just wanted to know.

Being thirsty, not peeing, dry mouth, headache, dizziness, nausea, fatigue, dry skin...

When you would need to go to the hospital is really a judgment call, and is a call best made by your surgeon. Someone who is just mildly dehydrated doesn't need emergency care at all.  If you are dehydrated enough that you aren't producing urine, that definitely requires immediate medical attention.

im going thru a symptom of dehydration right now, when i stand up i get dizzy and things start to go black, for the past 3 days ive been having a really hard time drinkin enough water, but eating some popsicals today is helping, i still dont want to drink but the dizzyness is going away

All of the symptoms mentioned above, and the color of your pee. If it is brown, instead of a nice yellow color, then you are dehydrated.
