can dehydration cause dizziness when standing up
The most common causes of dizziness when standing up are orthostatic hypotension, anemia, and dehydration. Orthostatic hypotension refers to a drop in blood pressure when standing. This condition is usually temporary; however, when it becomes chronic, medications to increase blood pressure are available. In addition, anemia can commonly cause dizziness, lightheadedness, and heart palpitations when a person stands up.
