Adults registering 140 mmHg or higher are considered to have high blood pressure but doctors are vague about what constitutes low blood pressure. Some say it could be considered low if the systolic pressure is below 100 mmHg. Most patients who are believed to have low blood pressure have a serious challenge in getting their blood pressure to rise. Typically, medical examiners do not regard this as a problem.
Updated:May 4,2015. To know if you have high or low blood pressure, you need to know what a healthy blood pressure level is. Optimal blood pressure is less than 120/80 mm Hg (systolic pressure is 120 AND diastolic pressure is less than 80).Within certain limits, the lower your blood pressure reading is, the better.s long as no symptoms are present, low blood pressure is not a problem. However, if your blood pressure is normally higher or if you are experiencing any of the symptoms listed above, your low pressure may have an underlying cause.
