<s>[INST] Hi I had a query regarding blood pressure. My mother aged 62 had blood pressure reading of  170/80 in the morning. After a few hours ,when measured again too, the systolic has remained above 140 consistently. The diastolic is between 70 and 80. Does she need medical attention immediately. [/INST] Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern, and would explain that her systolic blood pressure is above the normal limits of blood pressure, but we can not start treatment with the blood pressure values of one day. I recommend to closely monitor her blood pressure different times during the day, for a week (usually in sitting position after 10 minutes of relaxing). If her blood pressure are above 130/90 mm Hg values, a medical check up is necessary by her GP :- a careful physical examination- a resting ECG- a chest x-ray study - lab blood tests (complete blood count, fasting glucose, thyroid hormone levels, kidney and liver function tests, blood electrolytes, etc.), to exclude other possible secondary causes of high blood pressure. If her blood pressure are above these values for most of the time you should discuss with her doctor, the possibility of starting an antihypertensive therapy (a diuretic or an ACE inhibitor/ARB class are recommended). Hope to have been of help! Feel free to ask any other questions, whenever you need! Best regards,  </s>
