Many people with hypertension do not monitor their blood pressure because they do not feel any discomfort, but this is actually a great hidden danger. When hypertension occurs, if clinical symptoms such as headache, dizziness and other discomfort appear, it is easy to draw the attention of the patient and his or her family members, who will usually take their own blood pressure or go to the hospital for treatment. However, if the blood pressure is significantly higher without any discomfort symptoms (most of the reasons for the patient usually did not pay attention to, has tolerated), will make many people’s hypertension can not be timely detection and treatment, some patients even to the emergence of heart, brain, kidney and other damage, a measurement of blood pressure is very high, only to know that they have high blood pressure, at this time in fact, hypertension has been “latent “A long time. In addition, there are some people who know they have high blood pressure, because there is no uncomfortable feeling, but also do not want to receive treatment. The harm of high blood pressure will not be reduced because it does not cause discomfort. Long-term high blood pressure can cause the occurrence of heart, brain, and kidney damage in the human body, causing myocardial infarction, stroke, and renal arteriosclerosis. The risk of acute adverse events is greater when blood pressure is too high (generally greater than 180/110 mmHg). Therefore, regardless of discomfort, as long as the diagnosis of hypertension is made, it should be treated regularly under the guidance of a doctor. In addition, it is important for adults (>40 years old) to have their blood pressure measured once or twice a year so that hypertension may be detected and diagnosed early and missed diagnoses can be avoided.
