African Americans and Kidney Disease: Making the Connection

Kidney disease affects more than six million African American adults- one out of every six. Over time, kidney disease can lead to kidney failure. African

Americans are nearly four times more likely to develop kidney failure than Caucasians.

The body has two kidneys, which filter extra water and waste from blood to make urine.
They also help control blood pressure and make hormones the body needs to stay healthy.
Kidney disease prevents the kidneys from filtering blood as they should, which can cause
waste to build up in the body, leading to serious health problems.

The two main causes of kidney disease and kidney failure are diabetes and high blood
pressure – health conditions that are more common among African Americans than
whites. In fact, eight out of 10 new cases of kidney failure among African Americans are
due to diabetes or high blood pressure. Yet African Americans are less likely to know
that these conditions are connected to kidney disease. Heart disease and a family history
of kidney failure can also increase the risk of kidney disease.

Research funded by the National Institute of Diabetes and Digestive and Kidney Diseases
(NIDDK) at the National Institutes of Health uncovered an inherited trait that is more
common in African Americans. People with this trait who also have kidney disease are
twice as likely to develop kidney failure and tend to lose kidney function more quickly
than those without the trait.

What You Can Do?

“During National Kidney Month in March – and throughout the year – the NIDDK
encourages African Americans to make the connection between kidney disease and
diabetes, high blood pressure, family history and heart disease,” said Dr. Griffin P.
Rodgers, NIDDK director. “If you have a greater chance of developing kidney disease,
get tested – and remember to talk with others about kidney health.”

Getting Tested

Because early kidney disease has no signs or symptoms, getting tested is the only way to
know if you have the disease. Doctors test for kidney disease with a urine test that checks
for albumin, a type of protein in your urine, and a blood test that shows how well your
kidneys are filtering.

Getting tested can lead to earlier treatment, which can help you avoid or delay kidney
failure. If you have diabetes, high blood pressure, heart disease – or a mother, father,
sister or brother with kidney failure – don’t wait to get tested.

Reaching Out

Talk with family members to find out if there is a history of kidney disease, diabetes,
high blood pressure or heart disease in your family and share this information with your
health care provider. The NIDDK’s Family Reunion Health Guide has tips for talking
with relatives at family reunion gatherings or one-on-one.

You can also help others make the kidney connection by reaching out to members of your
faith community. The Kidney Sundays toolkit shows you how to raise awareness within
your faith community about the risks for kidney disease and the importance of getting

Staying Healthy

To take care of your kidneys and overall health, try to partake in regular physical activity and eat a healthy diet that includes plenty of fruit, vegetables, whole grains and low-fat
foods. Cut back on salt, limit how much alcohol you drink and if you smoke, take steps to

Also, remember to take any diabetes, high blood pressure or heart medicines as your
health care provider advises. Check your blood pressure and blood sugar levels regularly
to make sure they are in the appropriate range.

Knowing what can increase your chances of developing kidney disease can help you
prevent the disease or detect it early, so you can get treatment and avoid complications.
