Detailed Explanation of the Definition of Hypertension and Analysis of its Seven Key Contributing Factors

Hypertension and its Contributing Factors:

What is Hypertension? According to the World Health Organization's recommended blood pressure standards: Normal adult systolic blood pressure should be less than or equal to 140 mmHg, and diastolic blood pressure less than or equal to 90 mmHg. Hypertension is defined as systolic blood pressure greater than or equal to 160 mmHg and diastolic blood pressure greater than or equal to 95 mmHg. Blood pressure values ​​between these two ranges, i.e., systolic blood pressure between 141 and 159 mmHg and diastolic blood pressure between 91 and 94 mmHg, are considered borderline hypertension. To diagnose hypertension, multiple blood pressure measurements are necessary; at least two consecutive measurements with an average diastolic blood pressure of 90 mmHg or higher are required for a definitive diagnosis. A single elevated blood pressure reading is insufficient for a diagnosis, but follow-up observation is necessary.

Contributing Factors to Hypertension: Many factors contribute to hypertension. Here are some important factors: Women have a slightly lower rate of hypertension before menopause than men, but after menopause, their risk is not significantly different from men's, and may even be higher.

Personality is closely related to blood pressure. Changes in personality and emotions can cause many subtle changes in the body. For example, hormones that promote vasoconstriction are secreted more vigorously when angry or irritable, leading to increased blood pressure. If this continues for a long time, the risk of developing hypertension will greatly increase.

Hypertension is closely related to genetic factors. If both parents have hypertension, their children have a 46% chance of developing it; if one parent has hypertension, the chance is 28%; if both parents have normal blood pressure, the chance is only 3%.

Weight and blood pressure are highly correlated. Data shows that obese individuals have a 2-3 times higher prevalence of hypertension than those of normal weight.

Smoking accelerates atherosclerosis and causes elevated blood pressure. Studies have shown that about 10 minutes after smoking two cigarettes, increased secretion of adrenaline and noradrenaline leads to a faster heartbeat and elevated systolic and diastolic blood pressure. Furthermore, smokers are not only more prone to hypertension, but the nicotine in tobacco also affects the effectiveness of antihypertensive drugs, hindering the treatment of hypertension.

There is a clear relationship between alcohol consumption and blood pressure. As alcohol consumption increases, both systolic and diastolic blood pressure gradually rise. If this continues long-term, the incidence of hypertension will increase. Furthermore, excessive alcohol consumption also increases the risk of stroke. my country's hypertension prevention and treatment guidelines recommend that men consume no more than 30 ml of alcohol per day, and women no more than 20 ml.

Numerous surveys have shown that dietary structure has a significant impact on the occurrence and development of hypertension and stroke. Excessive sodium intake, excessive alcohol consumption, and excessive fat intake in the diet can all lead to hypertension. Other studies have shown that people who habitually stay up late are more prone to hypertension and even stroke; while those with a regular lifestyle and who go to bed early and wake up early have a lower incidence of hypertension.

With the continuous progress of social civilization, people's pace of life is accelerating, competition is becoming more intense, and pressure from all aspects is increasing. The human body will undergo a series of changes as a result, such as increased secretion of catecholamines, which causes vasoconstriction, increases the burden on the heart, and triggers hypertension.
