Hypertension can be categorized into two types, primary hypertension and secondary hypertension, and different types of hypertension have different causes. Primary hypertension is often caused by an inappropriate lifestyle, while secondary hypertension is due to the progression of underlying disease or failure to get good control. Causes of primary hypertension include family history of hypertension, obesity, smoking, high-fat and high-salt diet, prolonged exposure to mental stress (e.g., high work pressure, prolonged overtime work), and oral administration of certain medications (e.g., birth control pills, adrenocorticotropic hormones). Treatment is based on lifestyle changes and antihypertensive medication, such as smoking cessation, alcohol cessation, low-salt and low-fat diet, and appropriate weight reduction, etc. Oral antihypertensive medication, such as valsartan, nifedipine, etc., can be taken under the guidance of a doctor. 2. Secondary hypertension: when chronic kidney disease (such as chronic glomerulonephritis, nephrotic syndrome), endocrine diseases (such as pheochromocytoma, primary aldosteronism, Cushing’s syndrome) and other diseases progress or fail to get good control, can cause high blood pressure, called secondary hypertension. The key to treatment is to treat the cause, and the specific cause of hypertension needs to be clarified. There are many different reasons for elevated blood pressure, so if you have hypertension, you should consult the cardiologist to determine the cause and follow the doctor’s instructions.
