What is a low blood pressure reading? A low blood pressure reading is having a level that is 90/60mmHg, or lower. Only one of the numbers has to be lower than it should be to count as low blood pressure. In other words: if the top number is 90 or less (regardless of the botton number) this may be low blood pressure.
Low blood pressure means that your blood pressure is lower than normal. Another name for low blood pressure is hypotension (say hy-poh-TEN-shun). In most healthy adults, low blood pressure does not cause problems or symptoms. In fact, it may be normal for you. For example, people who exercise regularly often have lower blood pressure than people who are not as fit. But if your blood pressure drops suddenly or causes symptoms like dizziness or fainting, it is too low. It can cause shock.
