Most patients with asymptomatic hypertension have primary hypertension, but secondary hypertension is not excluded and requires relevant tests for differential diagnosis.
Hypertension can occur without any clinical manifestations, simply as an increase in blood pressure levels. Both primary and secondary hypertension can have similar manifestations, and it is not possible to determine between primary and secondary hypertension by the increase in blood pressure levels.
Most cases of primary hypertension do not have a clear cause and may be related to a variety of factors such as environmental and genetic factors. Secondary hypertension is more common in kidney disease, renal vascular disease, adrenal gland and other diseases. These diseases usually have an insidious onset and may only manifest as elevated blood pressure without other symptoms.
Patients with elevated blood pressure should monitor their blood pressure and take appropriate treatments under the guidance of their physicians. If necessary, relevant examinations should be conducted to clarify the cause of hypertension and actively treat it.
