Sudden rise of blood pressure may be caused by drug effects, mood fluctuations, disease effects and other reasons. If there is no history of hypertension in the past, the blood pressure suddenly rises, which may be caused by emotional overexcitement and sympathetic excitement. It is not a big problem if you can restore to normal by yourself. If the increase is particularly obvious, and the measurement at different times is higher than the normal value after repeated times, it is necessary to consider the use of antihypertensive drugs. If the blood pressure rises after taking some glucocorticoids, non steroidal anti-inflammatory drugs and other drugs, it may be caused by drug action. But pheochromocytoma, Cushing's syndrome, primary aldosteronism, renal artery stenosis, etc. can also lead to a sudden increase in blood pressure.
