A person with a blood pressure of 130/105 mmHg in an 18 year old boy after correct multiple measurements is not dangerous if there are no clinical symptoms, but it is a cause for concern. In patients with elevated blood pressure in youth, the first step should be to clarify whether the elevated blood pressure is primary or secondary, and secondary hypertension should be ruled out by adrenal ultrasound, catecholamine, thyroid hormone, and aldosterone hormone tests. After secondary hypertension is ruled out, young patients with elevated blood pressure are considered to have irregular diets, late nights, prolonged mental stress, obesity, smoking, and other factors. It is suggested that patients should have a low-salt and low-fat diet, ensure regular sleep, relax the mind, quit smoking and limiting alcohol, reduce weight and other treatments. If the blood pressure still continues to rise and does not fall, it is suggested to further visit the cardiology clinic and use medication under the guidance of the doctor.
