Hello. Thank you for your questıon and welcome to HCM. I read your query. As I can understand you are already diagnosed with hıgh blood pressure or hypertension and you are treating it with a beta-blocker. In a patient. without any other risk factors or co-morbidities, target blood pressure figures are under 140/90 mmHg. Once it is diagnosed, hypertension should be fought and kept within the above mentioned range, so it cannot produce further end-organ damages. However, these blood pressure fluctuations are normal, sınce it is a constant target of various hormonal, physıological and psychological changes that happen in the span of one single day. I am not worried about fluctuations. I am worried more about the high figures, even though you are already on hypertension treatment. Therefore, I would be recommend you to be put on a second drug for controlling your blood pressure. I would prefer a drug from the angiotensinogen converting enzyme inhibitor (ACE-I) class. You can further discuss this option with your cardiologist. I hope I was helpful. Wish you a good health. Take care, Dr. Meriton
