Re: low blood pressure
Your blood pressure is low if it's causing symptoms such as dizinness or lightheadedness or you are otherwise feeling unwell. If you are feeling fine, all is well.
Low blood pressure is not defined by any definite numbers. The presence of symptoms of low blood pressure is used instead in the diagnosis. The symptoms of low blood pressure develop when the arteries do not deliver enough oxygen to the brain, organs and bodily tissues. Some people are fine living with 90/50 blood pressure, while others develop symptoms of low blood pressure at higher blood pressure readings.
When in doubt, ask your doctor.
