Regardless of whether it is secondary hypertension or essential hypertension, clinical treatment is not based on the type to determine the severity of hypertension, but should be decided based on the patient’s specific level of blood pressure fluctuation, elevated blood pressure, and the presence of underlying diseases and target organ damage. Generally speaking, hypertension with higher blood pressure values, greater fluctuations, and the presence of underlying diseases and target organ damage is more serious. Whether it is secondary hypertension or primary hypertension, the severity is relatively high when there is a continuous rise in blood pressure, large fluctuations in blood pressure, and a combination of underlying diseases such as diabetes. If left untreated, it may lead to complications such as cerebral hemorrhage and coronary heart disease, and may cause damage to various organs of the body, such as the kidneys and liver, increasing the severity of the condition. The two types of hypertension differ in their causes and treatments. Primary hypertension, whose cause is more difficult to determine, is usually treated with medication to lower blood pressure and reduce complications; secondary hypertension, whose cause is clearer, requires treatment of the primary disease to regulate blood pressure, and if the primary lesion cannot be removed, antihypertensive medications are also used in conjunction with the treatment. If patients have elevated blood pressure, they should go to the hospital in time for an examination to clarify the specific level of blood pressure and to find out the cause of the disease, so that targeted treatment can be carried out as soon as possible.
