Blood Pressure Overview!

There are many factors to good health, and your blood pressure is one of them. In the simplest terms, it is the force or pressure that your blood exerts on the walls of your arteries and veins. Without this pressure, your blood would not circulate through your body carrying oxygen and nutrients to your cells while removing carbon dioxide and cellular waste from those same cells. Understanding this process will help you see why this area of ​​health is so important to your overall health. Because as your blood flows, so do you!

Mechanics of blood pressure

It all starts with your heart, which pumps blood from the heart into the arteries of your body. These large arteries narrow into smaller vessels called arterioles. These arterioles then narrow into even smaller vessels called capillaries. At the capillary level, your blood exchanges the oxygen and nutrients it carries in exchange for cellular waste products such as carbon dioxide and toxins. This blood then flows from the capillaries into your veins returning your blood to the heart.

As your heart pumps blood through your lungs, carbon dioxide is exchanged for oxygen. And as your blood is pumped through the liver, the liver removes most of your toxins.

Given this closed pumping system, there are two main factors that can contribute to changes in your blood pressure:

o Heart contraction force – Your heart acts as a pump. As your heart contracts, it pushes blood into its various chambers or into the large arteries that leave the heart. The force of your heart’s contraction will determine the force of the blood as it leaves the heart.

o Resistance to blood flow – When your blood leaves the heart, it will encounter resistance. This resistance can be caused by arteries that have aged and lost some of their elasticity. Or, resistance can come from plaque and other fatty deposits that change the internal shape of arteries and arterioles. Certain nerve impulses can trigger the endothelial cells that line the inside of your blood vessels to release nitric oxide.

Nitric oxide is the main signaling molecule of the cardiovascular system and determines how much the blood vessel will dilate (get bigger) or contract (get smaller). Finally, resistance will appear at the capillary level. If the capillary beds are restricted, the resistance to blood flow will increase. If the capillaries are open and flowing, then resistance to blood flow will be minimized.

As you can see, there are many factors that affect your blood pressure. Although the strength of the heart is one of them, most of the factors affecting this area occur after the blood leaves the heart. Because of this, in 90 to 95 percent of cases of high blood pressure, the cause is unknown. The remaining 5 to 10 percent of cases usually have a known cause, which could be:

o Kidney abnormality.

o A structural abnormality of the aorta, which is the large artery that leaves the heart.

o Narrowing of certain arteries due to a certain disease.

Most of these problems can be corrected. The challenge is to solve the remaining 90 to 95 percent of these cases.

Numbers!

When you go to the doctor’s office or hospital, one of the first things the nurse or health care provider does is take your blood pressure. They wrap a large cuff around the upper arm. They then manually pump air pressure into the cuff causing it to expand which puts pressure on your arm. Eventually the pressure in the cuff is higher than the pressure in the artery of your arm. This then stops the blood flow.

The next step is for the doctor to place the bell of his stethoscope over the artery in your arm and begin to slowly release the pressure in the cuff. They listen to two sounds. When your blood pressure is higher than the pressure in the cuff, then your blood will pulse again through the artery in your arm. This makes a sound and that first sound is called your systolic pressure. When the sound finally goes away, this last sound is called your diastolic pressure.

Your blood pressure is recorded as two numbers such as 110/70 mm Hg (millimeters of mercury). Systolic pressure is the first and higher number. It represents the pressure your heart creates when it contracts to pump blood from your heart to your body.

The second and smaller number is the diastolic pressure. This is the pressure of the blood in your arteries when your heart is refilling just before contracting again. Diastolic pressure is what allows your blood to continue circulating through your body.

The medical community has determined a normal range for both systolic and diastolic pressures. Anything above this normal range is considered either “pre-hypertension” or “hypertension”. The range is as follows:

o Normal blood pressure – anything below 120/80 mm Hg

o Prehypertension – If your systolic blood pressure is 120 to 139, or your diastolic blood pressure is 80 to 89, or both

o High blood pressure (hypertension) – if your systolic pressure is 140 or higher and/or diastolic pressure is 90 or higher

An estimated 72 million Americans have high blood pressure, meaning 1 in 3 adults have this “Silent Killer!” It is called that because there are usually no symptoms. This means that most of those who have high blood pressure do not even know it.

Now you might think that if there are no symptoms, what harm could it be to your body. Here is a list of the potential damage it can do if left unchecked:

o Increased risk of heart disease

o Increased risk of heart attack

o Increased risk of congestive heart failure

o Number one cause of stroke

o Increased risk of kidney failure

o Increased risk of peripheral artery disease

o Increased risk of aortic aneurysm

o Increased possibility of eye damage with vision loss

That’s quite a list of potential life-threatening health problems. You need to pay attention to your blood pressure and find ways to reduce your risk of this silent killer.

If you don’t know your blood pressure numbers, make it a priority to visit your pharmacist, local clinic or doctor’s office within the next seven days and have your systolic and diastolic blood pressure measured by a qualified person. It’s your first step in tackling this potential killer, especially if you want to slow the aging process and improve your overall health and well-being. Until next time, may we both grow old youthfully!
