For decades, potassium restriction has been a cornerstone of dietary management in patients with chronic kidney disease (CKD), but is it always necessary? Here to answer that exact question is Dr. Deborah Clegg.

Dr. Clegg is the Vice President for Research and a Professor in the Department of Internal Medicine at Texas Tech University Health Sciences Center in El Paso.
