Blood pressure of 180 mmHg can be seen in both physiologic and pathologic conditions. Certain physiological factors cause blood pressure 180mmHg, usually can be recovered. However, if a hypertensive patient has a blood pressure of 180mmHg, after active treatment, the blood pressure can usually be controlled at a normal level. Under the influence of physiological factors such as strenuous exercise, emotional excitement and overwork, normal people may have their blood pressure temporarily reach 180mmHg, which can be normalized after rest and self-regulation. If a hypertensive patient’s blood pressure reaches 180mmHg, he or she is in Grade 3 hypertension, which is usually more dangerous. After active treatment, the blood pressure can usually be controlled at a normal level. If the patient also combines risk factors such as advanced age, dyslipidemia, obesity, or target organ damage, as well as diabetes, then recovery is usually not easy. When a hypertensive patient’s blood pressure reaches 180 mmHg, he or she should seek medical attention to clarify the cause of the condition and monitor the blood pressure regularly.
