Diabetes and CKD

• Diabetes is a disease in which you have too much sugar in your

blood

• Over time, high blod sugar can damage small blood vessels in your

kidneys and cause CKD

CHRONIC KIDNEY DISEASE

High blood pressure and CKD

• High blood pressure means your heart is working too hard.
• Blood flows through your arteries, veins, and blood vessels with too much

force.

• This can damage the vessels in your kidneys and cause CKD
