Dear Ask The Doctor: Why do i get dizzy when i stand up after sitting for an extended period. Dear John: The dizziness you are experiencing after standing up after sitting for an extended period is due to postural hypotension. Getting up to quickly after prolonged sitting down causes the blood pressure to drop suddenly transiently decreasing blood flow to theupper part of the body. Your doctor will do a simple test to determine whether you have postural hypotension or not. If there is a difference of more than 20 mmHg in blood pressure reading wile lying down and standing up, a diagnosis of postural hypotension is made. Your doctor may need to rule out other cardiac conditions such as rhythms abnormalities that may present with similar symptoms. |
