Children and adolescents are the flowers of our country, the future of our nation, and the jewel in the palm of every parent’s hand. We take care of their growth, but inevitably, we care too much about our children, which leads to one or another problems, such as the hypertension in children and adolescents that we are going to talk about today. In the clinic, there were several children who came to the clinic with complaints of dizziness and headache, because they were children, sometimes it is easy to ignore the blood pressure problems, and there were several small patients with systolic blood pressure as high as 150 mmHg. Let’s get to know. First, what is hypertension in children? Hypertension in children, like hypertension in adults, is divided into primary and secondary. Primary hypertension in children is mostly manifested as mild to moderate elevation of blood pressure, usually without self-perception, no obvious clinical symptoms, and not easily detected unless regular physical examination. Its causative risk factor is mainly obesity. Left ventricular hypertrophy is the most prominent target organ damage in children with essential hypertension, accounting for 10%-40% of hypertension in children. If a child’s blood pressure is found to be significantly elevated, it may be secondary childhood hypertension; renal hypertension is the first cause of secondary hypertension, accounting for about 80% of secondary hypertension. How is it diagnosed? Blood pressure measurement in children is different from that of adults. Children must use a suitable cuff to maintain accurate values, and the physiological blood pressure values of children change gradually with age, and children’s blood pressure is lower than that of adults. Children are growing and developing, and their organ functions are not yet fully developed, so medication should be used with caution. Third, what is the goal of blood pressure reduction? Generally speaking, the blood pressure of children under 10 years old is 80+(2Xage) for high pressure and 2/3 of high pressure. 100/60 mmHg for 10 years old, for example. Therefore, age should be considered when measuring blood pressure in children. Fourth, how to treat it? In children with primary hypertension or hypertension without target organ damage, the systolic blood pressure should be controlled at 95 mmHg. In children with secondary hypertension or with target organ damage, the blood pressure should be controlled at 90 mmHg systolic. We advocate “treating the disease before it happens”, which means emphasizing lifestyle changes. 1. Reduce weight and control diet. Today’s material life is abundant, children and adolescents generally eat too much, too much nutrition; plus now children generally like to eat desserts, Western food, these contain high calorie food is easy to make children fat, obesity is also a risk factor for hypertension, so for overweight children, less snacks, eat more fresh vegetables and fruits, blood pressure can be improved. It is very important to develop good habits. 2, more exercise. Children can do some activities outdoors such as hide-and-seek, to improve body metabolism, weight loss are beneficial, if the child is secondary hypertension, we need to identify the cause for the cause of treatment. In short, children should have a scientific and reasonable diet, but also more exercise, so as to grow up healthy and strong.
