Hello doctor! I went to the military entrance examination, my blood pressure was 150, but when I got home, I measured 120, but I regularly measure it but my blood pressure is always stable at 120. So the doctor asked me if it was because I was stressed or because I was sick. what reason? I hope the doctor can help me. I would like to thank the doctor more!

Hello, grandchild! Listening to her description, we thought of the pathology "White Coat Hypertension". What it is specifically: In a nutshell, white coat hypertension occurs when the blood pressure measured in the hospital or clinic is always high (140/90 mmHg or higher). But when you go home, your blood pressure returns to normal and does not affect your health. This phenomenon mainly comes from psychological anxiety, nervousness when going to the doctor, causing the heart to beat faster and increase the pressure on the blood vessel walls. In many cases, systolic blood pressure can be up to 30 mmHg higher than it actually is. We have met many cases like you... By instructing to monitor your blood pressure at home or wearing a 24-hour blood pressure monitor, the diagnosis will be more accurate. Thereby will have the best advice for your child's disease.
To be sure that your child does not have high blood pressure, he or she should visit and consult a Cardiologist at the Vinmec Health System hospitals nationwide.
