Introduction
The normal blood pressure range is defined as systolic pressure between 90–139 mmHg and diastolic pressure between 60–89 mmHg. We further classify the above blood pressure ranges into optimal blood pressure, which is systolic <120 mmHg and diastolic <80 mmHg, and high-normal blood pressure, which is systolic 120–139 mmHg and diastolic 80–89 mmHg.
The normal blood pressure range is related to various factors such as genetics, age, lifestyle habits, mental state, and environmental influences, with diet playing a particularly important role. So what exactly is the normal blood pressure range?
Normal Blood Pressure Range
The normal blood pressure range is defined as systolic pressure between 90–139 mmHg and diastolic pressure between 60–89 mmHg. Blood pressure can be categorized into ideal levels and high-normal levels. Ideal blood pressure is when systolic pressure is below 120 mmHg and diastolic pressure is below 80 mmHg. High-normal blood pressure refers to systolic pressure ranging from 120 to 139 mmHg and diastolic pressure from 60 to 89 mmHg. Individuals in the high-normal category should remain vigilant, improve their lifestyle habits, regularly monitor their blood pressure, and take preventive measures to avoid progression to hypertension. The diagnostic criteria for hypertension are as follows: Stage 1 hypertension is diagnosed when systolic pressure ranges from 140–159 mmHg and diastolic pressure from 90–99 mmHg. Therefore, a blood pressure reading of 147/97 mmHg falls within the range of Stage 1 hypertension.
Hypertension can lead to severe functional impairments in certain organs. For example, it may cause cardiac hypertrophy, enlargement of the heart, and even heart failure or myocardial infarction. It can also result in cerebral artery hardening, narrowing, or blockage, potentially leading to hemorrhage, stroke, or even death. Hardening of the renal arteries and glomerular arterioles may lead to loss of kidney function and ultimately renal failure.
Low blood pressure primarily affects the body by causing inadequate perfusion to vital organs. Insufficient myocardial perfusion can lead to myocardial ischemia and angina. Reduced cerebral perfusion may cause dizziness, visual disturbances, and in severe cases, unilateral limb dysfunction or speech difficulties. We hope this information has been helpful. Wishing you good health and a happy life!
