Primary hypertension (or hypertension as the people refer to it) is a lifelong disease, caused by genetic factors and acquired environment, etc., and is not yet curable. Many patients refuse to take medication or do not take it regularly because they are not uncomfortable or have clinical manifestations. The danger is enormous because long-term elevation of blood pressure or repeated large fluctuations can lead to blood flow disorders and blood vessel rupture in important organs such as heart, brain and kidney, causing malignant events such as myocardial infarction, cerebral infarction and brain hemorrhage. Therefore, in order to reduce or delay the occurrence of various cardiovascular and cerebrovascular complications. Need to do the following: 1, regular monitoring: monitor blood pressure, understand the pattern of blood pressure fluctuations during the day, but also pay attention to the characteristics of seasonal fluctuations in blood pressure, generally in the summer when blood pressure tends to be lower, in the winter when the cold blood pressure may be higher. Should be under the guidance of the doctor to adjust the drug to smoothly control blood pressure. 2. Start with small doses: Generally speaking, you should start taking antihypertensive drugs in small doses and gradually adjust the dosage every 1-2 weeks under the guidance of your doctor according to the changes in your specific condition in order to control your blood pressure smoothly. 3, observe the adverse reactions: Although the overall antihypertensive drugs have few adverse reactions, but if discomfort occurs during the medication, you should seek medical treatment as soon as possible. 4, blood pressure control should be gradual: Be sure to abandon the wrong view that “the faster the blood pressure is lowered, the better”, generally within a few weeks – months to control blood pressure within the individual appropriate “target range”. In the case of hypertensive crisis, the situation is special, but it is important to control blood pressure gradually rather than as quickly as possible. In addition, in addition to regular medication, a proper diet, a good lifestyle (e.g., keeping a good combination of work and rest, adequate sleep, and a relaxed mood), appropriate exercise, quitting smoking and limiting alcohol, and weight control all contribute to blood pressure control.
