Hypertension in 13 year olds belongs to children’s hypertension, if there is a mild to moderate elevation of blood pressure, usually without obvious clinical symptoms, and considered to be related to obesity, it can be treated without medication, and lifestyle interventions can usually be given. If the blood pressure remains elevated after lifestyle intervention, or if there is a sudden and significant increase in blood pressure, it is important to consider whether there is a possibility of secondary hypertension. If renal hypertension is to be treated with antihypertensive drugs, the first step is to give a small dose of an antihypertensive drug, such as an angiotensin-converting enzyme inhibitor, commonly used in the clinic, such as Lotensin, or angiotensin receptor antagonists, such as timosartan or valsartan, and calcium antagonists, such as Lovoxil or Baxinotoxin, and such drugs can also be given. If one antihypertensive drug is unsatisfactory, a combination of two or more can be considered, and diuretics can also be used to treat hypertension in children.
