Re: dizziness what should I do
You may have high bloodpressure problem. When rising from the bed, push up slowly to a sitting position with legs dangling off the bed. Sit there for 2 minutes, raise feet up and down on toes, stand up and stand for 3 minutes, then take off and do whatever you had planned. Pumping legs up and own helps to pump blood back to the head.
At night when you are at rest blood pools in the legs and when you get up fast the blood has not had time to reach the head again.
To determine whether this is your problem, take bloodpressure before getting out of bed and again after standing for 3 minutes. If bloodpressure drops significantly, then this is most likely the cause.
Same thing happens when rising from a chair too fast after sitting for a while.
Best to see doctor for proper diagnosis.
