Types of low blood pressure. Doctors often break down low blood pressure (hypotension) into different categories, depending on the causes and other factors. Some types of low blood pressure include: Low blood pressure on standing up (orthostatic, or postural, hypotension).This is a sudden drop in blood pressure when you stand up from a sitting position or if you stand up after lying down. Ordinarily, gravity causes blood to pool in your legs whenever you stand.s a result, the brain lessens the heart rate, decreasing blood pressure even further. This causes more blood to pool in the legs and less blood to reach the brain, leading to lightheadedness and fainting. Low blood pressure due to nervous system damage (multiple system atrophy with orthostatic hypotension).
