For a long time, many patients have a misconception in the treatment of hypertension, that is, the use of antihypertensive drug usage as if it were a cold medicine. It is to take the medication when the blood pressure is high and stop when the blood pressure drops. The ideas are certainly varied, some afraid of trouble, some to save money, unknowingly caused a hidden danger – “blood pressure fluctuations”. We know that human blood pressure is constantly changing throughout the day in accordance with environmental changes and changes in our own emotions, the reason we do not feel it is because there is a regulatory center within the nervous system of our body, which can stabilize blood pressure in the right range, that is, to ensure that the blood supply to all parts of the body is adequate, and will not cause discomfort. The occurrence of hypertension indicates a weakening or loss of this regulatory ability within the body, and therefore requires medication to help maintain it. For people with hypertension, early morning fluctuations in high blood pressure are even more frightening because they can cause a greatly increased risk of coronary heart disease and cerebral infarction. A recent British study cited here is more illustrative. An Oxford University clinical observation published recently in the world-renowned medical journal The Lancet found that, in addition to the absolute value of blood pressure, fluctuations in blood pressure are also a valid indicator of brain bleeding, heart failure, angina and other heart and brain diseases. Blood pressure fluctuations are more likely to trigger brain hemorrhage than simple hypertension. Therefore, both medical personnel and patients themselves should pay sufficient attention to fluctuations in blood pressure. Studies have also found that some antihypertensive drugs reduce blood pressure fluctuations while others increase them. Therefore, when choosing medications, you should try to use those that can reduce blood pressure fluctuations; at the same time, it is essential to take medications regularly every day.
