First, the primary hypertension medication is not reasonable. This includes two factors: first, the blood pressure is unstable due to irregular medication. Theoretically, patients should take their medication before the peak of blood pressure, but it is impossible for patients to get up every day at 5 o’clock in the morning to take their medication. Many patients often remember to take their medication only after they have finished breakfast, cleaned up the dishes and sent their children to school, by which time the peak blood pressure has often passed and the medication does not work as it should. The second is that the patient is taking short-acting antihypertensive drugs and does not take them in a timely manner as required or misses them. For blood pressure to be stable, it is best to take long-acting drugs. Take long-acting drugs in the time required to take is not very strict, a little earlier and a little later is not a big problem. Secondly, when hypertensive patients suffer from other diseases, they can also make their blood pressure fluctuate. For example, during an attack of cholecystitis can make the blood pressure unstable, acute anxiety attacks …… Third, doctors diagnose secondary hypertension based only on large fluctuations in blood pressure. Many doctors do not realize that primary hypertension accounts for 95% of cases and secondary hypertension only accounts for a minority. However, most doctors only pay attention to primary hypertension. Fourth, hypertension can cause many other diseases that can lead to unstable blood pressure during the onset of these diseases. For example, a patient with hypertension in a stable stage will certainly experience fluctuations in blood pressure when coronary artery disease or angina attacks. If a patient sees a doctor in this situation, the doctor will have to find out what is causing the blood pressure fluctuation and treat it at the root. Blood pressure fluctuations caused by other diseases, the increase in blood pressure is only a symptom and should not be confused, so it is easy to misunderstand if only the symptoms are treated without treating the root cause.
