Hypertension is clinically divided into primary hypertension and secondary hypertension.

Primary hypertension is characterized by elevated blood pressure without other symptoms, and the current clinical diagnostic methods cannot determine the cause of the blood pressure rise, which is referred to as primary hypertension.

Secondary hypertension occurs as a result of other diseases, with the most common being hyperthyroidism, glomerulonephritis, arteritis, atherosclerosis, and other diseases causing high blood pressure.

After the onset of hypertension, effective antihypertensive drugs must be used for treatment. Hypertension is not to be feared, but the damage it causes to the body is.

(Specific medications should be used under the guidance of a physician)

Is high diastolic pressure considered high blood pressure?

If the diastolic blood pressure exceeds 90 mmHg, hypertension should also be considered. Patients with a high diastolic blood pressure who do not actively undergo hypotensive treatment can suffer long-term damage to target organs such as the heart, brain, and kidneys, as well as severe hypertensive complications. For patients with high diastolic blood pressure, it is also necessary to adopt effective lifestyle adjustments and choose clinically frontline antihypertensive drugs for long-term treatment. Only by effectively controlling elevated diastolic pressure in the long term can severe target organ damage and hypertensive complications be avoided, thus improving the clinical prognosis for patients with hypertension.

What is the blood pressure for gestational hypertension?

Pregnancy-induced hypertension refers to a series of pathophysiological changes caused by elevated blood pressure in women during pregnancy. It is a severe complication of pregnancy that can have serious effects on both the mother and the fetus. The diagnostic standard for hypertension during pregnancy is the same as in non-pregnant periods, that is, a blood pressure greater than 140/90mmHg can be diagnosed as pregnancy-induced hypertension. However, pregnancy-induced hypertension can be classified based on whether it is combined with other conditions, as well as the severity of the condition. Depending on the severity, pregnancy-induced hypertension can be divided into categories such as gestational hypertension, pre-eclampsia, eclampsia, chronic hypertension, and chronic hypertension with superimposed pre-eclampsia. These classifications are mainly based on the severity of the condition, and it is essential to treat pregnancy-induced hypertension with standardized care.

The difference between hypertensive nephropathy and renal hypertension

Hypertensive nephropathy and hypertension due to kidney disease need to be differentiated, as this affects the treatment approach and prognosis assessment differently. Hypertensive nephropathy refers to patients with long-term high blood pressure, which causes arteriosclerosis of small vessels leading to renal pathology. Often, there is also arteriosclerosis in other organs, such as the retinal arteries, which can be confirmed through funduscopic examination. On the other hand, hypertension due to kidney disease occurs when a patient has kidney disease first followed by hypertension, where the causes and types of kidney diseases vary and can frequently lead to hypertension. The difference between the two lies in the sequence of occurrence. Hypertensive nephropathy is characterized by initial high blood pressure and commonly associated with arteriosclerosis in other vessels, which can be preliminarily identified through funduscopic examination. In cases of hypertension due to kidney disease, the patient has other kidney disorders first, followed by hypertension. If a patient's 24-hour urine protein quantification exceeds 2g, it is likely due to kidney disease rather than hypertensive nephropathy. If differentiation remains challenging, kidney biopsy can be performed for further differentiation.

Is it called hypertension if the diastolic blood pressure is high?

High diastolic pressure, which is an increase in diastolic pressure, is also considered hypertension when the diastolic pressure exceeds 90mmHg. If you have hypertension, it is essential to have a formal medical examination at a hospital, such as blood tests for lipids and glucose to check for diabetes and hyperlipidemia. Blood tests are also done to evaluate liver and kidney functions, to see if there are any kidney diseases causing the increase in blood pressure. Additionally, under the guidance of a doctor, conduct ambulatory blood pressure monitoring to observe the overall situation of blood pressure increase within 24 hours. Based on the results of the blood tests and ambulatory blood pressure monitoring, determine whether antihypertensive medication is needed and which type of medication to use.

How to lower high blood pressure

Patients with hypertension need to adopt a comprehensive approach to reduce their blood pressure, primarily comprising two aspects: On one hand, they should regulate their lifestyle for treatment purposes, which includes maintaining a long-term low-salt and low-oil diet, consuming more vegetables and fruits, regularly engaging in physical exercises and labor, keeping a healthy weight level, avoiding fatigue, not staying up late at night, and maintaining a good emotional state. On the other hand, suitable antihypertensive medications should be chosen based on the specific conditions of the patients and used long-term. If necessary, a combination of antihypertensive drugs may be required. Effective control of blood pressure can only be achieved by combining lifestyle adjustments with medication.
