The first time a patient is found to have high blood pressure, it is best to be hospitalized. Because hypertension is divided into two main categories, one is primary hypertension and the other is secondary hypertension, the purpose of hospitalization is mainly to check if there is any possibility of secondary hypertension. If secondary hypertension is ruled out, then it is primary. Secondary hypertension is caused by diseases of the adrenal glands or renal arteries, including primary aldosteronism, and other endocrine diseases. In this case, it is necessary to treat the cause of the disease, and only after the cause of the disease is resolved will the hypertension improve. Primary hypertension is mainly treated with oral medication, and the choice and dosage of oral medication is adjusted according to the blood pressure to achieve the purpose of stabilizing the blood pressure. It is best to be hospitalized so that the condition can be better observed, judged and treated.
