If the systolic and diastolic readings fall into different categories, the higher value should be taken for classification. For example if your reading was 161/98 you would be classified as having moderate hypertension. If your reading classifies you with any level of hypertension i.e. mild through to very severe, you should ask your doctor or pharmacist to assess you professionally at least once a year. Low blood pressure (Hypotension) and high blood pressure (Hypertension) can only be diagnosed by a qualified healthcare professional, such as a doctor or pharmacist.
If you have any concerns or questions, please contact your doctor or pharmacist.
