Normal high value blood pressure has a systolic blood pressure of 120 to 139 mmHg and/or a diastolic blood pressure of 80 to 89 mmHg. Adolescent’s blood pressure of 137/65 mmHg belongs to normal high value blood pressure. It may be caused by physiological factors such as high mental stress, or pathologic factors such as hyperthyroidism and kidney disease. Blood pressure can be adjusted through lifestyle changes and medications. 1. Physiological factors: adolescents with high study pressure, mental stress, poor sleep, obesity, etc. may lead to normal high blood pressure. Lifestyle changes, such as low-salt and low-fat diet, regular exercise, weight control, attention to work and rest, reduce mental stress, maintain a good state of mind, etc., should be actively changed to reduce blood pressure to below 120/80mmHg. 2. Hyperthyroidism: the increase of thyroid hormone in the early stage of hyperthyroidism increases the sympathetic excitability, which can cause the blood pressure to be at the normal high value, should consult the doctor in time, and can be applied under the guidance of the doctor to actively control the primary disease such as methimazole and other antithyroid drugs, so as to adjust the blood pressure. 3. Kidney disease: early kidney disease patients due to the activation of renin – angiotensin – aldosterone system, can cause blood pressure in the normal high value, should consult the doctor in time, can be under the guidance of the application of diuretics (such as furosemide, etc.) and other medications to actively treat the primary disease, so as to adjust the blood pressure. It is recommended to go to a regular hospital in time to clarify the cause of high blood pressure, and adjust the blood pressure under the guidance of the doctor.
