What is Hypertension
Hypertension, or high blood pressure, has no noticeable symptoms. That’s why it is commonly referred to as a “silent killer,” Untreated high blood pressure can lead to a greater risk for stroke, heart attack, or other heart damage. Normal blood pressure is less than 120 (systolic) over 80 (diastolic) —often written as 120/80 mm Hg (read 120 over 80 millimeters of mercury). Your doctor should measure your blood pressure during each visit. If your doctor finds that your blood pressure is consistently higher after several visits, you may be diagnosed with hypertension.
The odds are good that most people will have high blood pressure in their lifetime. In fact, more than 74 million American adults have high blood pressure.1 Approximately 90% of people with normal blood pressure at age 55 are at risk for developing high blood pressure as they get older.2 However, it’s important to know that even though high blood pressure is quite common, it is still a dangerous condition that should be monitored closely by a doctor.
If you have recently been diagnosed with hypertension (high blood pressure), there are positive steps you can take. There are many lifestyle changes and treatment options available to help lower blood pressure.
During a regular physical exam, a doctor or other healthcare provider uses asphygmomanometer (blood pressure cuff) to check blood pressure. This common device should be familiar to you: it consists of a cuff that fastens around the upper arm and is attached to a bulb. The doctor inflates the cuff by squeezing the bulb. The doctor then releases the air from the cuff and listens with a stethoscope for the first heartbeat that can be heard. As the pressure drops, the point where the first sound is heard represents systolic blood pressure. The point where the heartbeat fades and disappears is diastolic blood pressure.
Your doctor may also check for hypertensive retinopathy, which is damage to the blood vessels in the eyes caused by high blood pressure. Since high blood pressure puts people at risk for stroke and kidney failure, the exam will also cover all of the major organs such as the brain, lungs, and kidneys, to check for damage. Depending on the results of these tests, more tests (eg, urinalysis, blood tests, and ECG) may be necessary.
If high blood pressure is well controlled, most serious complications may be avoidable. However, for people with very high, uncontrolled blood pressure, serious problems could develop. Talking to your doctor and taking steps now to lower blood pressure are the best ways to prevent more serious problems from developing.
High Blood Pressure Risk factors
Age and Sex. The risk of developing high blood pressure increases as you age. Most cases of high blood pressure are diagnosed in men, until the age of 45. From age 45 to 54, men and women are equally at risk for high blood pressure. After the age of 54, women are actually more likely to have high blood pressure than men.
Family History. People with relatives who have high blood pressure are more likely to develop high blood pressure.
Ethnicity. People of African American and Native American ethnicity have very high rates of high blood pressure, and the situation appears to be a growing problem. Compared with Caucasians, African Americans develop hypertension earlier in life, and their average blood pressures are much higher. Hispanics have a higher ratio of diabetes and obesity compared with Caucasians, and have additional risk factors for developing hypertension.
Diet. People who regularly eat foods that are high in salt are more susceptible to high blood pressure.
Obesity. People who are overweight are at risk for many illnesses, including high blood pressure.
Stress. Studies have shown that people with heightened anxiety, intense anger, and suppressed expression of anger were more at risk of developing high blood pressure.
People with high blood pressure usually experience no symptoms unless their blood pressure is extremely high, or if they have had high blood pressure for a long time. In these cases, damage may occur in major organs, such as the heart, brain, and kidneys, as well as in the small blood vessels in the eyes. It’s important to remember that if left untreated, high blood pressure may lead to serious complications.
