Hypertension patients need long-term medication to control the condition, patients can not stop taking medication after the blood pressure is stable, stopping medication will lead to blood pressure rebound, cerebral hemorrhage, heart failure, coronary atherosclerosis, and so on. 1. Blood pressure rebound: stopping the drug will lead to blood pressure rebound, which makes the patient dizziness, headache and other symptoms. 2. Cerebral hemorrhage: stopping the drug will lead to blood pressure fluctuations, blood pressure fluctuations on the blood vessels caused persistent damage to the blood vessels thickening, reduced elasticity, endothelial damage, and even cerebral hemorrhage occurs. 3. Heart failure: after stopping the drug due to increased blood pressure, the heart needs stronger contraction force to supply blood to all organs of the body, resulting in left ventricular hypertrophy, induced hypertensive heart disease, and even heart failure. 4. Atherosclerosis of the coronary arteries of the heart: stopping medication will lead to atherosclerosis of the coronary arteries of the heart, may induce acute coronary syndromes, such as unstable angina pectoris and acute myocardial infarction, and may even jeopardize the life of the patient. Hypertensive patients need to follow long-term medical advice to take medication on time, do not stop taking medication, stop taking medication after the blood pressure fluctuations caused by damage to vital organs is irreversible, hypertensive patients must be controlled within the standard range of blood pressure, so as not to cause adverse effects.
