African American Women And High Blood Pressure
(BlackDoctor.org) — High blood pressure happens when blood can’t flow easily
through your blood vessels. This puts pressure on your vessels, which damages
the vessels and strains your heart. As a result, blood doesn’t flow as well to
your organs, and you can have a heart attack, stroke, or kidney failure.
High blood pressure has no symptoms. See your doctor once a year to have your
blood pressure checked.
One out of three Americans has high blood pressure. African American women of
all ages develop high blood pressure more often than non-Hispanic white women.
Some things increase your chances of having high blood pressure: increasing age
(middle aged or older), diabetes, obesity (or being overweight), alcohol use,
eating too much salt, a family history of high blood pressure, and not
Making some lifestyle changes can help prevent or control high blood
• If you are overweight, lose weight. Losing just 10 pounds
can lower your blood pressure.
• Get moving. Aim for 30 minutes of exercise a day, most
days of the week. Try taking the stairs instead of the elevator. Or, walk during
breaks at work.
• Eat right. Eat lots of fruits, vegetables, and whole
grains. Choose low-fat dairy products. Eat less salt.
• Don’t smoke. If you smoke, try to quit.
• If you drink alcohol, have no more than one drink per day.
How Being Black Affects Your Blood Pressure
If you’re black, pay special attention to your blood pressure — even if you
think you’re healthy.
That’s because high blood pressure (hypertension) affects certain groups of
people differently than others. And for black people in the United States, high
blood pressure often occurs earlier in life, is more severe and has more
Find out why you may be at greater risk of high blood pressure if you’re
black and what steps you can take to protect yourself.
Why being black increases your risk of high blood pressure
If you’re black and living in the United States, you’re more likely than a
person of another race to develop hypertension, and to develop it earlier in
your life. And once you have the disease, you’re more likely to have severe
complications, such as stroke, kidney failure and heart disease. In addition,
blacks often don’t get treatment until their blood pressure has been high for so
long that vital organs have already started to suffer damage.
Researchers are still studying precisely why some blacks are at greater risk.
The issue essentially boils down to the age-old nature vs. nurture debate.
- Genetic susceptibility (nature). Genetics
has historically been blamed for a higher rate of hypertension among blacks.
That thinking has been supported by evidence that blacks as a group respond
differently to certain blood pressure medications and are more sensitive to the
blood pressure raising effects of sodium. Newer data, however, indicate that
blacks living traditional lifestyles in rural African countries experience few
blood pressure problems. This may point the finger, instead, at environmental
- Environment (nurture). Worldwide, the
rate of hypertension among blacks is not unusually high compared with that of
whites. In the United States, though, about 41 percent of blacks have
hypertension, compared with 27 percent of whites. Some researchers suggest that
difference is the result of socioeconomic disparities between blacks and whites.
Blacks have a higher rate of obesity, may eat a diet high in sodium and low in
potassium, and may experience more socioeconomic stress because of societal
prejudices. All of those are linked with high blood pressure.
A healthy lifestyle is important regardless of skin color
For researchers, resolving these issues is important because doing so can
help improve the prevention and treatment of high blood pressure among blacks in
general. While researchers continue to grapple with these issues, you can take
steps today to care for yourself and your family members.
No matter what your skin color, certain unhealthy lifestyle habits can
increase your risk of developing high blood pressure or interfere with your
efforts to lower your blood pressure when it’s too high. You can minimize your
lifestyle-related risks by following these guidelines:
- Maintain a healthy weight.
- Exercise regularly.
- Eat a healthy diet.
- Reduce sodium in your diet.
- Limit alcohol consumption.
- Avoid tobacco products and secondhand smoke.
- Cope with stress in a positive way.
In addition, talk to your doctor about how often you should get your blood
pressure checked. Although most healthy adults need a check-up only every two
years, if you’re black, you may need to have your blood pressure checked more
frequently — perhaps annually — since you’re at a higher risk.
Following these kinds of healthy habits can also benefit black youngsters
because of the increased risk of hypertension they face. If you’re concerned
about your child’s health, talk to his or her pediatrician about age-specific
blood pressure goals.
Treating high blood pressure when you’re black
Anyone can develop dangerous complications from high blood pressure. But if
you’re black, these complications tend to be more severe and are more likely to
result in death.
- Heart attack
- Kidney disease
Treating your high blood pressure effectively can help reduce your chance of
these complications. Living a healthy lifestyle is the cornerstone of treating
high blood pressure. But many people also must take blood pressure medications
Your doctor may recommend that you first try a thiazide-type diuretic — the
same general recommendation as for white people starting medication treatment.
Your doctor may also suggest taking a calcium antagonist (calcium channel
blocker), either by itself or along with a diuretic.
If you have severe high blood pressure or complications, you might need
The goal is to reduce your blood pressure to at least 140/90 millimeters of
mercury (mm Hg. Getting it even lower is better for your health.
Taking charge pays off in the long run
Although you may be more likely to develop high blood pressure and face a
greater risk of complications than your white counterparts, don’t get
The good news is that if you follow a healthy lifestyle and stick with your
treatment regimen, your blood pressure is likely to respond well. And you’ll
reap the same rewards for controlling your blood pressure that anyone would — a
longer and healthier life.
