1. When should I take the medication? Many patients are accustomed to taking their medication after waking up in the morning, as often recommended by doctors or in past guidelines. However, many patients have an early morning blood pressure “morning spike”, which occurs between 5 and 6 am. Some patients also have high blood pressure at night. Therefore, these patients should take antihypertensive drugs after dinner and before bed. 2, to pay attention to, don’t overdo it. In recent years experts have spoken every day and guidelines have repeatedly said that to effectively prevent stroke, it is necessary to keep blood pressure falling steadily for 24 hours. This is true in theory. But something went wrong in practice. Some elderly people, after retirement, attach great importance to health care and take their blood pressure frequently every day, even once every two hours, and even get up at night to do so. When the blood pressure fluctuates, they get nervous. Go to the doctor, some doctors prescribe a bottle of fast-acting blood pressure drugs, such as Captopril. Some of the old couple have high blood pressure, every hour to test each other’s blood pressure, the more you test the more nervous, the more nervous the higher, a bottle of 100 tablets of Captopril less than a week to contain an empty. This is a kind of “blood pressure anxiety”. The number of types of antihypertensive drugs is increasing, the dose is increasing, because after using 3-5 kinds of antihypertensive drugs, the blood pressure still fluctuates, so in the previous period was misled to over-treatment, received the renal function pulse sympathetic nerve radiofrequency ablation, after the operation blood pressure fluctuations continue. I have persuaded many elderly hypertensive patients to change their self-measurement behavior. I suggested “pay attention, don’t overdo it!” Blood pressure not only stabilized quickly, but the type and dose of blood pressure-lowering medication needed was dramatically reduced. If you want to know whether your blood pressure is falling smoothly 24 hours a day, you can do a 24-hour ambulatory blood pressure monitoring when necessary, rather than taking your own blood pressure too often at home. 5. Is a perennial blood pressure of 90/60 mmHg, or even sometimes 80/50 mmHg, low blood pressure? Do I need to treat it? If you can maintain this blood pressure level all year round, it is normal. It is not hypotension. People with this level of blood pressure are at a much lower risk of stroke. No medication is needed and no treatment is required. Sometimes these patients have symptoms of weakness, dizziness, palpitations …… that are easily attributed to “low blood pressure”, but in reality have little to do with blood pressure and are most likely related to lack of sleep and anxiety/depression.
