Orthostatic hypotension, also known as postural hypotension, is a form of low blood pressure in which a person's blood pressure falls significantly when suddenly standing up or stretching. Clinically, it is defined as a fall in systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg when a person assumes a standing position.

People with orthostatic hypotension can experience dizziness, lightheadedness, and fainting. Orthostatic hypotension can be triggered by a number of factors, including medications, dehydration, and certain medical conditions. It is often treated by identifying and addressing the underlying cause, as well as by making lifestyle changes such as drinking more fluids and avoiding standing up too quickly.
