March is National Kidney Month — an awareness effort to encourage people who are at risk of chronic kidney disease, often due to diabetes or high blood pressure, to get screened. On the Mayo Clinic Radio podcast, Dr. Ladan Zand, a Mayo Clinic nephrologist, discusses chronic kidney disease and offers tips to keep your kidneys healthy. Also on the podcast, Dr. Valeria Cristiani, a Mayo Clinic pediatrician, discusses fluoride varnish and oral health for children. And Dr. Dawn Davis, a Mayo Clinic dermatologist, explains the importance of sunscreen to protect against sun damage.
