How do you treat low blood pressure?

-sometimes, when i get up after lying down, i feel a little light headed, and cant see. im also young. and i was searching on Y!A and it could be a sign of low blood pressure. and i heard this is common in teens, esp females.



i also heard that dehydration is a cause for this. is there any way to treat it (besides drinking more water?)If you BP is below 90/60 and you suffer from dizziness, faintness and actual fainting spells you have a low BP problem.



A higher salt intake will usually raise your BP.
