Blood pressure 90-130 has reached the diagnostic criteria for hypertension, which is still serious and requires vigilance and timely hospitalization to avoid delays. Blood pressure 90-130 should refer to diastolic blood pressure of 90mmHg and systolic blood pressure of 130mmHg, which is within the normal range of systolic blood pressure, while the diastolic blood pressure just reaches the standard of hypertension, which can be diagnosed as hypertension. The diagnostic criteria for hypertension are systolic blood pressure greater than or equal to 140mmHg, and/or diastolic blood pressure greater than or equal to 90mmHg. The main danger of hypertension, besides clinical symptoms such as headache and dizziness, is damage to target organs. To the heart, it may lead to hypertensive heart disease, ventricular hypertrophy or even heart failure; to the blood vessels, it may lead to hardening of blood vessels and reduction of elasticity; to the brain, it may lead to cerebral ischemia or cerebral hemorrhage; to the kidneys, it may lead to glomerulosclerosis and so on. Therefore, the treatment of hypertension must be started as early as possible to avoid damage to target organs. Blood pressure of 130/90mmHg can be controlled without antihypertensive drugs by improving lifestyle, such as low-salt and low-fat diet, quitting smoking and restricting alcohol, strengthening exercise, controlling body weight, and maintaining a calm state of mind. At the same time, closely monitor the blood pressure, if you can not control, timely consultation, under the guidance of the doctor drug treatment.
