Blood pressure refers to the lateral pressure per unit area of the blood in the blood vessel, that is, the pressure. It is customary to use millimeters of mercury (mmHg) as the unit. The heart has periods of contraction and relaxation. When the heart contracts, the left ventricle pumps blood out to the aorta. The aortic pressure produces high blood pressure, also known as systolic pressure. Next, the heart relaxes and blood flows into the right atrium. At this time, the pressure is lowest, which is called low blood pressure or diastolic blood pressure. Under normal circumstances, the human body has normal blood pressure. However, due to the influence of external factors and the increase in age, the blood pressure cannot be avoided. So what is high blood pressure?
What is high blood pressure? Blood pressure is the pressure of blood circulation on the arterial walls of the body. Hypertension refers to high blood pressure. That is, too high blood pressure will put too much pressure on the blood vessel wall. High blood pressure is a serious condition that increases the risk of heart, brain, kidney disease and other diseases. A major cause of premature death immediately. If the blood pressure is measured on two different days, and the systolic blood pressure is ≥140 mmHg (mmHg) on both days and/or the diastolic blood pressure is ≥90 mmHg on both days, it can be diagnosed as hypertension. In the past, only medical instruments could be used to measure blood pressure, but now some high-end smart watches can be used for blood pressure monitoring. Moreover, the data monitored by the smart watch is not different from the data measured on the medical device.
What are the risk factors for high blood pressure? The risk factors that can be changed are: unhealthy diet (excessive salt intake, eating foods rich in saturated and trans fats, low intake of fruits and vegetables), lack of physical activity, smoking, drinking, and being overweight or obese. Unchangeable risk factors include: family history of hypertension, age 65 or older, diabetes or kidney disease and other coexisting diseases.
What are the common symptoms of hypertension? Hypertension is called the "silent killer." Most people with high blood pressure do not realize they have this problem because they may have no warning signs or symptoms. Therefore, it is important to measure blood pressure regularly. If there are symptoms, it may be the following symptoms: morning headache, nosebleeds, irregular heartbeat, vision changes, and tinnitus. Severe high blood pressure can cause fatigue, nausea, vomiting, confusion, anxiety, chest pain, and muscle tremors.
Blood pressure measurement by health professionals is the only way to diagnose hypertension. Measuring blood pressure is quick and painless. Although individuals can also use automated equipment to self-test their blood pressure, it is important for health professionals to assess the risks and related conditions.
What are the possible complications of not controlling high blood pressure? Other complications of high blood pressure include the potential for serious damage to the heart. Excessive pressure can cause arteriosclerosis, reducing blood and oxygen flow to the heart. Increased pressure and decreased blood flow can cause: Chest pain is also called angina. If the blood supply to the heart is blocked and the cardiomyocytes die due to lack of oxygen, heart disease will occur. The longer the blood flow is blocked, the greater the damage to the heart.
Heart failure occurs when the heart cannot deliver enough blood and oxygen to other vital organs of the body.
Arrhythmia can cause sudden death. High blood pressure can also cause the arteries that supply blood and oxygen to the brain to rupture or block, triggering a stroke. In addition, high blood pressure can cause kidney damage, leading to kidney failure.
How to reduce the burden of high blood pressure? Lowering high blood pressure can prevent heart attacks, strokes, kidney damage, and other health problems.
How to prevent Reduce salt intake, eat more fruits and vegetables, exercise regularly, do not use tobacco, reduce alcohol consumption, limit the intake of high-saturated fat foods, and eliminate/reduce trans fats in the diet.
manage Reduce and control stress, check blood pressure regularly, treat high blood pressure, and manage other diseases.
Blood pressure monitoring function of smart watch Some high-end smart watches on the market basically have a blood pressure monitoring function. Wearers can monitor their blood pressure through the blood pressure monitoring function of the smart watch, and the blood pressure data will be displayed directly on the screen. At the same time, it will appear on the corresponding APP. The blood pressure monitoring function is realized mainly by its powerful sensor. Sensors are the basis for its basic monitoring functions. No matter if it is a major manufacturer, such as Apple, Huawei, Samsung, or Xiaomi. It is also a small factory Veepoo, Huami and other brands. Using smart watches for blood pressure monitoring, smart watches can automatically send information to your private doctor for review, which is another matter. At this time, the smart watch can just play the role of its information storage.
