Hypertension is a common cardiovascular disease that seriously endangers human health. At present, 200 million people are suffering from this disease nationwide, and the rising trend is obvious. However, the awareness of the disease is “three low” status, that is, only 40.5% of patients know they have hypertension (low awareness rate), only 24.7% of them receive treatment (low medication rate), only 6.1% of patients adhere to the treatment of blood pressure standards (low control rate). It is better to see a doctor than to prevent a disease, and everything is based on prevention, and this is especially true for the prevention and treatment of hypertension. The theme of this year’s World Hypertension Day is salt and hypertension: two silent killers. Hypertension can be prevented by eating a healthier diet that is low in salt, low in fat and rich in fiber and consuming fresh fruit. It is especially important for people with a family history of hypertension to take care of a healthy lifestyle in advance to prevent hypertension from being triggered by improper lifestyle habits. For the majority of hypertensive patients, especially to do “eight attention”: one to reduce salt intake, salt intake should be less than 5 grams per day; two to ensure a reasonable diet, limit fat intake, eat more fresh fruits and vegetables; three to effectively control weight; four to quit smoking; five to limit alcohol; six to increase physical activity, can be used jogging, fast walking, swimming, bicycling and other forms of physical activity. Sixth, we should increase physical activity, which can take the form of jogging, brisk walking, swimming, cycling, etc., and each activity is generally appropriate for 30 to 60 minutes; seventh, we should pay attention to the combination of work and rest, and maintain a relaxed mood; eighth, if the blood pressure is well controlled through 3 to 6 months of non-pharmaceutical treatment, it can be maintained. If it is ineffective, then start applying antihypertensive medication, not because of young or no obvious symptoms. The medication for hypertension should vary from person to person depending on the condition. With antihypertensive drugs generally start with small doses and gradually increase the dose. When a drug alone is not effective, it is advocated to use a combination of drugs to reduce adverse reactions, enhance synergistic effects and better protect target organs. In general, blood pressure should be controlled to <140/90 mmHg, and to <130/80 mmHg or lower for those with diabetes and chronic kidney disease. Medications have certain side effects, so use them under the guidance of a physician and do not reduce or stop them easily. As the saying goes, "less salt, less fat and more exercise, quit smoking and limit alcohol to reduce stress, take medication on time is the key, and follow the doctor's orders is the guarantee".
