There are many causes of hypertension, which may be caused by primary or secondary factors. Smooth lowering of blood pressure can be carried out by treating the causes, improving life style and taking oral antihypertensive drugs. 1. Primary factors: Some patients may have high blood pressure due to a combination of genetic factors, environmental factors, etc. In this case, it is necessary to improve the lifestyle, such as low-salt and low-fat diet, avoiding mental stress, abstaining from smoking and alcohol, and avoiding staying up late at night, etc. If the blood pressure is still not controlled satisfactorily, it may be necessary to improve the lifestyle. If the blood pressure control is still unsatisfactory, you need to follow the doctor’s instructions to take oral medication for treatment, such as nifedipine extended-release tablets/control tablets, amlodipine tablets, valsartan, candesartan ester tablets and so on. 2. Secondary factors: some patients may have elevated blood pressure due to secondary factors, such as chronic renal insufficiency, aortic narrowing, renal artery stenosis, pheochromocytoma, etc. Aortic narrowing, renal artery stenosis, pheochromocytoma, etc. can be treated by surgery, etc., and after removing the cause of the disease, the blood pressure can be controlled smoothly at the normal level.
