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.

Causes of pregnancy-induced hypertension

There are many reasons that can lead to the occurrence of hypertensive disorders during pregnancy. Normally, due to reasons related to the mother herself or being under the age of 18 or over 35, the risk of developing hypertensive disorders during pregnancy may increase. Additionally, dietary and environmental influences such as a high-salt diet, excessive fatigue, and mental stress can lead to the development of pregnancy-induced hypertension. In some cases, after the development of pregnancy-induced hypertension, it may trigger diseases in other organ systems, leading to severe issues with the placenta, causing complications such as placental abruption, hypoalbuminemia, and cerebrovascular accidents.

Causes of high blood pressure

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)

How is hypertensive nephropathy treated?

Long-term hypertension can lead to abnormal kidney structure and function, also known as hypertensive nephropathy. Once hypertensive nephropathy is diagnosed, comprehensive treatment measures are often adopted, including both pharmacological and non-pharmacological treatments. In terms of non-pharmacological treatment, patients should maintain a low-salt diet in their daily life, focusing on a light diet, with a daily salt intake of about 4 grams. Regarding pharmacological treatment, the main goal is to control the patient's blood pressure and reduce urinary protein. Medications that can be used include angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists. Any of these medications can be chosen and used long-term to control blood pressure, protect kidney function, and reduce urinary protein. (Medications should be used under the guidance of a physician, and self-medication should be avoided.)

How to treat hypertensive encephalopathy

The treatment goal for hypertensive encephalopathy is mainly to rapidly reduce blood pressure to a reasonable range. Typically, intravenous antihypertensive drugs are administered to decrease blood pressure by 20%-25% within the first hour, followed by oral antihypertensives or continued intravenous treatment to further reduce it to a more reasonable level. Hypertensive encephalopathy often accompanies cerebral edema, and patients may experience increased intracranial pressure. At this point, it is necessary to administer dehydrating agents such as mannitol to treat the cerebral edema. If the patient experiences seizures, which can cause an increase in blood pressure or difficulty in reducing blood pressure, sedative anticonvulsant drugs must be administered to control the seizures. If the patient shows signs of heart failure, diuretic treatment should be initiated. Additionally, high concentration oxygen therapy under high pressure should be administered, which can be delivered through nasal cannula. If nasal oxygen therapy is ineffective, non-invasive ventilation or even intubation with invasive ventilation may be used to provide high concentration positive pressure oxygen therapy.

Can high blood pressure be hereditary?

Hypertension has a certain level of heritability, and research indicates that if parents have hypertension, their children’s risk of developing this condition significantly increases. Of course, genetic factors are only one of the reasons for the development of hypertension. The presence of genetic factors does not necessarily lead to hypertension; postnatal environmental factors are also very important. Maintaining good lifestyle habits over time, including healthy dietary habits, regular physical exercise, reasonable weight control, and a positive mindset can help prevent hypertension. Moreover, even without a family history of hypertension, poor lifestyle habits can still lead to the development of the condition.
