What is normal blood pressure for teenagers?

Clinically, there is a disease that can cause high blood pressure in adolescents. We know that adolescents are in a period of growth, during which their bodies develop rapidly and their blood pressure is generally normal. However, some children always find that their blood pressure is too high when they are nervous or go to the hospital. This situation should be paid attention to, and attention should be paid to daily psychological construction. So, what is the normal blood pressure for teenagers?

1. Disease characteristics

Adolescent hypertension has the following characteristics:

1. The systolic blood pressure (commonly known as high pressure) is high while the diastolic blood pressure (commonly known as low pressure) is not high. The high pressure can reach 140-150 mmHg, and the low pressure does not exceed 85-90 mmHg.

2. Normally, there is no discomfort. Only after excessive fatigue or strenuous exercise do you feel some discomfort, such as dizziness, chest tightness, etc. Because the symptoms are not obvious, they are often ignored by teenagers, parents and medical staff.

3. Part of the cause is related to the drastic changes in neuroendocrine system during puberty, accelerated development of internal organs, and the inability of blood vessels to keep up with the development of the heart. After puberty, blood pressure will gradually return to normal levels.

To prevent hypertension in adolescence, first of all, we must educate teenagers to actively participate in physical examinations organized by the school and understand their blood pressure so that they can discover it in time, further confirm the diagnosis, find out the cause and treat it in time; secondly, we must implement the general principles of preventing hypertension, such as paying attention to the combination of work and rest, avoiding excessive fatigue; keeping emotions stable to avoid blood pressure fluctuations due to emotional fluctuations; exercising appropriately, doing more exercises that are beneficial to heart health, such as swimming, running, etc.; not smoking, not drinking, and maintaining good behavioral habits. Dietary issues should also be adjusted.

2. Causes

The main cause of adolescent hypertension is that the body's organ systems develop rapidly during adolescence, and the heart also develops. The heart's contractility is greatly improved, but at this time, blood vessel development often lags behind the heart, leading to increased blood pressure. In addition, during puberty, the development of endocrine glands is enhanced, hormone secretion increases, the excitability of the nervous system increases, and the autonomic nervous regulation function is unbalanced, which can also cause high blood pressure. At the same time, in specific environments such as reviewing for exams, adolescents are under high mental stress, which causes dysfunction of the cerebral cortex and loss of normal regulation of the subcortical vasomotor center, leading to increased tension in the arterioles and increased peripheral circulatory resistance, which also increases blood pressure.
