Hypotension, also known as low blood pressure, is one of the causes of dizziness, particularly when going from lying down to sitting or standing. “When you get up too quickly from a sitting or lying position and your blood doesn’t travel as quickly up to your head, you can experience a ‘head rush’ feeling,” explains Sherry Ross, MD, ob-gyn and women’s health expert at Providence Saint John’s Health Center in Santa Monica, California.
