The Basics About High Blood Pressure
We have written about high blood pressure here in recent weeks
have noted that it is referred to as the Silent Killer" and will continue to post in the future on both hypertension and diabetes in our mix of topics. But first I want to provide you with a basic background post on high blood pressure so you know exactly what it is
'Normal' Blood Pressure Values
There has been a lot of talk lately about blood pressure. Blood pressure is the force of movement of blood throughout the arterial and vascular circulatory systems. Oxygenated blood sent rushing into the arteries after the left ventricle in the heart contracts. The blood vessels accommodate blood flow to maintain normal blood pressure values. When the vessels become narrow, the amount of blood flow is restricted causing a rise in blood pressure.
Blood pressure readings are measured by two different values, the systolic and diastolic pressures. After the heart contracts, it has forced blood into the arteries at its greatest strength. This is the systolic pressure. As the pressure in the arteries relaxes, the pressure decreases. This is called the resting, or diastolic pressure. When represented in written form, such as 120/80, the top number is the systolic reading, and the lower number is the diastolic. This blood pressure reading, 120/80, is the average measurement of a wide range of readings, representing normal blood pressure values. The value that concerns most is the diastolic, or "resting" reading. When it is consistently higher than 80, hypertension is present. Pressure fluctuates naturally throughout the day with activity, rest, excitement, emotions, stress, etc., this is normal and does not necessarily indicate that anything is wrong.
What's Considered "High" Blood Pressure?
When blood pressure readings are consistently 140/90 or higher, even at periods of rest, hypertension is present. Readings over 160/95 are of concern, because this is considered the danger zone. Hypertension is called the "Silent Killer" because it has no symptoms until the pressure is extremely high. According to the American Heart Association, 68 million Americans have one or more forms of heart or blood vessel disease. There is no cure for hypertension, the medical term for high blood pressure. It must be medically managed with prescribed antihypertensive agents, combined with diet and exercise.
There are quite a few factors that contribute to altering normal blood pressure values creating hypertension. As we age, the arteries are not as elastic and restrict blood flow, also known as "hardening of the arteries" or arteriosclerosis. Other factors are family history of hypertension and heart disease, use of oral contraceptives, alcohol, illegal substances, weight gain, sedentary lifestyle, smoking, stress-related issues, and a high fat, high sodium diet. This list of course, is not all inclusive.
You Can Get Your Blood Pressure Under Control
Have no fear; it is possible to maintain normal blood pressure values if you have hypertension. Regular visits with your physician are of great importance, as well as complying with prescribed medication regimens, regular aerobic exercise, and maintaining a healthier diet. By engaging in regular physical activity, we feel better, because our bodies are more efficient. Aerobic activities such as walking, running, swimming, dancing, and aerobic exercise machines like treadmills, stairmasers, and rowing machines will not only allow you to be more fit physically, mentally, and spiritually, but your blood pressure will be lower as well. Diets low in sodium and high amounts of fat also work to lower blood pressure. Whole grains, fruits, and vegetables are very plentiful and have a variety of uses, providing you with a smorgasbord of healthy food choices..
If you are diagnosed with high blood pressure, you should see your doctor every three or four months until you get it under control. If you cant afford to do do it, you should at least invest in a blood pressure monitor to check it yourself. That way you'll be able to twell if it's getting too high, which if it does, definitely see your doctor. Unless you get your blood pressure under control, it will shorten your life.
