    ### Instruction:
    What are the treatments for Orthostatic Hypotension ?
    ### Response:
    When orthostatic hypotension is caused by hypovolemia due to medications, the disorder may be reversed by adjusting the dosage or by discontinuing the medication. When the condition is caused by prolonged bed rest, improvement may occur by sitting up with increasing frequency each day.
