Orthostatic hypotension is a condition in which a person experiences a sudden drop in blood pressure when they stand up from a sitting or lying down position. This can cause dizziness, lightheadedness, and even fainting. It is caused by a decrease in blood flow to the brain when the person stands up, resulting in a decrease in blood pressure. Treatment for orthostatic hypotension may include lifestyle changes such as increasing salt and water intake, avoiding alcohol and caffeine, and exercising regularly. Medications may also be prescribed to help regulate blood pressure.
