These patients in particular need an advocate, and I wanted to be that individual in their lives.”

About Kidney Disease

In the United States, more than 37 million adults are estimated to have kidney disease, also known as chronic kidney disease (CKD)—and approximately 90 percent don’t know they have it. About 1 in 3 adults in the U.S. are at risk for kidney disease. Risk factors for kidney disease include: diabeteshigh blood pressureheart diseaseobesity, and family history. People of Black or African American, Hispanic or Latino, American Indian or Alaska Native, Asian American, or Native Hawaiian or Other Pacific Islander descent are at increased risk for developing the disease. Black or African American people are about four times as likely as White people to have kidney failure. Hispanics experience kidney failure at about double the rate of White people.
