Hypertension
Which is more dangerous, low blood pressure or high blood pressure?
Blood pressure is a crucial indicator for maintaining human life. Both low blood pressure and high blood pressure can pose significant risks to the body. High blood pressure can lead to arteriosclerosis, and prolonged high blood pressure can cause cardiovascular and cerebrovascular diseases, with severe cases leading to cerebral ischemia and myocardial infarction. Low blood pressure affects the blood supply to vital organs and also brings negative factors to the body. Extremely low blood pressure can also endanger human life. Therefore, whether it is low blood pressure or high blood pressure, it should be correctly treated and improved under the guidance of a doctor to ensure the health of the body.
Symptoms of hypertension
Hypertension is a common and frequently occurring disease clinically. Mild hypertension often has no clinical symptoms and is usually detected during physical examinations when measuring blood pressure reveals an increase. In cases of severe hypertension, individuals with long-term high blood pressure may experience dizziness, a feeling of pressure in the head, and headaches. In serious cases, symptoms can include tinnitus and palpitations, requiring the use of effective antihypertensive medications for management. If patients with hypertension do not use medications to manage their condition, long-term high blood pressure can cause significant harm to the body, leading to cardiovascular and cerebrovascular diseases, hypertension-induced heart disease, and stroke. (Please use medications under the guidance of a doctor.)
The difference between hypertensive crisis and hypertensive encephalopathy
Both hypertensive encephalopathy and hypertensive crisis involve a rapid increase in blood pressure, symptoms of headache, restlessness, nausea and vomiting, palpitations, shortness of breath, and blurred vision, with systolic pressure increasing to 200 mmHg and diastolic pressure to 120 mmHg, typically presenting similar clinical blood pressure readings. The main difference between the two is that hypertensive encephalopathy is based on excessively high blood pressure in patients with severe hypertension. Furthermore, hypertensive encephalopathy can lead to clinical signs of cerebral edema and increased intracranial pressure, whereas hypertensive crisis occurs when blood pressure suddenly rises over a short period, causing symptoms due to excessive secretion of catecholamines driven by increased sympathetic nervous excitement.
