Definition and Importance of Blood Pressure
Blood pressure is defined as the pressure of blood against the walls of blood vessels. It is expressed by two numbers: the systolic pressure, which is the higher number, indicating the pressure when the heart beats; and the diastolic pressure, which is the lower number, reflecting the pressure when the heart rests between beats. Normal blood pressure is typically around 120/80 mmHg. Its importance is highlighted by its role in maintaining essential bodily functions, including oxygen delivery and nutrient transport to organs and tissues. Elevated blood pressure levels can strain the heart and damage blood vessels, leading to various cardiovascular diseases.
How Blood Pressure is Measured
Blood pressure is measured using a device known as a sphygmomanometer, which can be manual or digital. The measurement is taken around the upper arm. For accurate results, certain protocols should be followed: the person should be seated comfortably for at least five minutes, with their back supported and feet resting on the floor. It is essential to measure blood pressure multiple times to get a consistent reading, as variables like stress and time of day can influence results. The healthcare provider will then interpret the numbers to determine if the levels are normal, elevated, or indicative of hypertension.
Consequences of Unmanaged Hypertension
Unmanaged hypertension can lead to severe health complications over time. The risks include:
- Heart Disease: High blood pressure can cause the heart muscle to thicken, risking heart failure.
- Stroke: Increased pressure in the blood vessels can lead to clogging or bursting, resulting in a stroke.
- Kidney Damage: Hypertension can damage the blood vessels in the kidneys, affecting their ability to filter blood effectively.
- Vision Loss: Damage to the blood vessels in the eyes may lead to vision impairment or blindness.
