orthostatic hypotension

Orthostatic hypotension is a condition where your blood pressure drops significantly when you stand up from sitting or lying down. This sudden drop can cause dizziness, lightheadedness, or even fainting. It happens because your body struggles to quickly adjust blood flow to maintain stable pressure when you change positions. It's often related to dehydration, prolonged bed rest, or certain medications. While occasional dizziness can be normal, persistent symptoms may need medical attention to determine the underlying cause and possible treatment.
