<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi - am a 56 year old male. The low figure on my blood pressure seems high. It varies between 13093 morning reading; 13488 6pm reading before meal. The lower figure seems to be consistently higher. Am fit and dont have salt, dont smoke, dont drink. Please could you advise?  <response>: Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that these values of diastolic blood pressure may indicate the beginning of high blood pressure. I recommend you to closely monitor your blood pressure and perform some tests to exclude other possible causes of secondary high blood pressure: - a chest X-ray study-complete blood count for anemia-kidney and liver function tests-thyroid hormone levels-fasting glucose-blood electrolytes- inflammation tests PCR, ESR. You should discuss with your doctor on the above issues. For the moment there is no need to start antihypertensive therapy. I recommend continue on your healthy lifestyle. Hope you will find this answer helpful! Kind regards,
