Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away. Low blood pressure is also known as hypotension. People with a reading of around 90/60, or less are commonly regarded as having low blood pressure. Some people who have low blood pressure experience symptoms as a result of it. There may be an underlying cause that could need treatment.
