CKD Causes and Symptoms

?

Diabetes and high blood pressure together are the primary causes for more than two-thirds of cases of CKD in the U.S. These two conditions, especially if uncontrolled, cause damage to blood vessels and kidneys. At first, this damage happens slowly over time, which makes noticing symptoms difficult.

Early detection and a kidney-friendly lifestyle can help keep your kidneys working well and give you the best chance for a longer and healthier life.

Other causes of CKD include sudden injury to kidneys from a severe illness or reaction to certain drugs or chemicals. It’s also possible for CKD to result from a birth defect, inherited disease, autoimmune disease or other conditions.

  • Fatigue 
  • Trouble sleeping 
  • Decreased appetite

What is YOUR GFR?

This is an important question to ask your doctor. Your GFR tells you how well your kidneys are working. A GFR over 60 means your kidneys are filtering well. Under 60? Talk to your doctor. A combination of good healthcare and a commitment to a kidney-friendly lifestyle can prolong your kidney function.
