So, some people get low blood pressure because they were born that way, in the same way that some people are tall and some people are short, some people have high blood pressure, and some people have low blood pressure, and there’s a big genetic factor in that. Very rarely, people with low blood pressure can have dizziness when they stand up suddenly, and sometimes they can even faint from that. So, low blood pressure is usually not too much of a problem, and in fact, in some cases, it’s good to have low blood pressure. The exception is if it causes dizziness, and then it needs to be treated.
