Blood pressure at 140/110mmHg for a long period of time is considered high blood pressure, which needs to be treated according to the cause of the disease and take antihypertensive drugs as prescribed by the doctor. If it is a transient increase in blood pressure, it can be left untreated for the time being, and the blood pressure can be measured regularly. Hypertension can be categorized into primary hypertension and secondary hypertension. Primary hypertension is mostly related to family genetics, irregular living and dietary habits. 140/110mmHg is classified as Grade 3 hypertension and requires oral antihypertensive medication under the guidance of a physician. If the blood pressure cannot be controlled smoothly, multiple antihypertensive drugs can be used in combination as prescribed by the doctor. A low-salt, low-fat diet is also needed in daily life. Secondary hypertension is often secondary to other diseases and requires further examination to clarify the cause. Common diseases include pheochromocytoma, nephrotic syndrome, renal artery stenosis and so on. The cause of the disease must be targeted to take drugs or surgical treatment, generally after the control of the primary disease, the blood pressure can be returned to normal in most cases. If you find elevated blood pressure, you need to go to the hospital, follow the doctor’s instructions for medication, you can not just use drugs.
