Why are African Americans at increased risk for chronic kidney disease?

African Americans and other ethnic groups are at increased risk for chronic kidney disease (CKD). Diabetes, the leading cause of CKD, is more common in these groups. Also, high blood pressure, the second leading cause of CKD, appears more often in African Americans than in other ethnic groups. Many experts believe these groups may have an inherited tendency to develop these diseases. When combined with other things such as being overweight, this tendency may lead to disease. Staying at a normal weight and getting enough exercise are very important for these groups to help prevent diabetes and high blood pressure.
