The internationally accepted diagnostic criteria for hypertension are: systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg. Hypertension can be divided into two main categories: primary hypertension and secondary hypertension. Patients with secondary hypertension are less common, and people usually speak of primary hypertension. Hypertension is one of the most common chronic diseases, and its prevalence continues to grow year-round. It is also the most important risk factor for cardiovascular and cerebrovascular diseases, and its high morbidity, disability and mortality rates seriously threaten human health. Currently, there is no cure for hypertension. Existing experience shows that the most effective way to control hypertension is to prevent and control. 1, the so-called “prevention”, that is: improve lifestyle, including smoking and alcohol cessation, salt restriction, more fruits and vegetables, weight loss, reduce mental stress, maintain psychological balance. 2, the so-called “treatment”, that is: the treatment of complications. Clinicians often prescribe different antihypertensive drugs according to the specific situation of the patient. After a period of drug treatment, the patient’s blood pressure will gradually return to normal. At this point, some patients will want to stop using antihypertensive drugs, okay? Simply put: Many people believe that the goal of hypertension treatment is simply to lower blood pressure to below 140/90 mmHg. In fact, this view is incorrect. In addition to lowering blood pressure to normal, we also need to prevent and treat various complications associated with hypertension, such as complications of the heart, brain, kidneys and other important organs. By controlling blood pressure, we can reduce the incidence of cardiovascular and cerebrovascular events, prevent and control kidney function damage, etc. If you do need to stop or change your medication, you should also gradually reduce the dosage and switch smoothly under the guidance of your doctor or pharmacist.
