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.
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.
