The upper number (numerator) in the reading indicates the systolic pressure, whereas the lower number (denominator) represents the diastolic pressure. Though a blood pressure level of 120/80 mmHg is considered optimal, having a systolic pressure between 91 and 119 mmHg and diastolic blood pressure between 61 and 79 mmHg is considered normal.
- If it is not associated with any symptoms, such as weakness, dizziness, or fatigue, it would not be considered hypotension and will usually be left untreated.
- The doctor may monitor you only if you have other medical conditions, such as heart problems, or are taking medications that cause low blood pressure.
