Analysis of Hypertension in Adolescents: Causes, Characteristics, and Scientific Management Guidelines

Prevention of Hypertension in Adolescents: The normal blood pressure of teenagers entering puberty is close to that of adults. If blood pressure is higher than 140/90 mmHg at rest, it can be diagnosed as hypertension, known as adolescent hypertension.

The main cause of adolescent hypertension is the rapid development of various organ systems during puberty, including the heart, which develops rapidly and its contractility increases significantly. However, vascular development often lags behind the heart, leading to elevated blood pressure. Additionally, the increased development of endocrine glands and hormone secretion during puberty, along with increased excitability of the nervous system and an imbalance in autonomic nervous system regulation, can also cause elevated blood pressure. Furthermore, under specific stress conditions such as exam preparation, adolescents may experience high levels of mental tension, leading to dysfunction of the cerebral cortex and loss of normal regulation of the subcortical vasomotor center. This results in increased tension in small arteries and increased peripheral circulatory resistance, which can also cause elevated blood pressure.

Adolescent hypertension is generally a temporary phenomenon during puberty. According to medical experts, most adolescents with adolescent hypertension have good physical development and mostly normal organ function. Normally, there are no significant symptoms, only mild dizziness and weakness appearing during excessive exercise or fatigue. Blood pressure is mainly characterized by a significant increase in systolic pressure, reaching 140-150 mmHg, while diastolic pressure is mostly within the normal range.

Although mild hypertension in adolescence may be asymptomatic for a considerable period, it can slowly damage blood vessels, the heart, kidneys, and brain. Some individuals may experience sudden death due to ruptured blood vessels, blockages, or heart attacks without any apparent discomfort. Studies show that in people in their thirties and forties, under high stress, the rate of fatal heart attacks is more than twice that of non-adolescent individuals. Therefore, hypertension in adolescence should never be taken lightly.

Since hypertension in adolescence is usually temporary, after puberty, the cardiovascular system rapidly matures and reaches equilibrium, and blood pressure returns to normal. Therefore, early use of antihypertensive drugs is generally not recommended; instead, establishing a healthy lifestyle is essential to achieve normal blood pressure. The following points are essential:

(1) Maintain emotional stability and optimism. Anger, sadness, fear, excessive laughter, and arguments can all lead to elevated blood pressure.

(2) Maintain a regular lifestyle and ensure sufficient sleep. Avoid staying up late.

(3) Eat a balanced and scientific diet. Reduce your intake of fatty meats and high-cholesterol foods such as animal fats and fish roe. Increase your consumption of fresh vegetables and fruits, as well as milk, beans, and mushrooms. Limit sodium intake to less than 5 grams per day.

(4) Quit smoking and drinking alcohol, as smoking causes vasoconstriction and increases peripheral vascular resistance.

(5) Engage in regular physical exercise, at least half an hour daily, but avoid strenuous activity.

If symptoms do not improve or blood pressure continues to rise after three months of these measures, further examination is necessary, and antihypertensive medication should be taken under the guidance of a doctor.
