If you’re looking for the 10 signs that may indicate kidney problems, common warning signs include:
-
Swelling in the feet, ankles, legs, hands, or around the eyes
-
Changes in urination — much more or less urine, frequent urination, or nighttime urination
-
Foamy or unusually bubbly urine, which can sometimes indicate protein in the urine
-
Blood in the urine (pink, red, or cola-colored urine)
-
Persistent fatigue or weakness
-
Nausea or vomiting, especially with advanced kidney dysfunction
-
Loss of appetite or unexplained weight loss
-
Itchy or unusually dry skin
-
Muscle cramps, particularly in the legs
-
Shortness of breath, which can occur when fluid builds up or anemia develops
Important: Chronic kidney disease often causes few or no symptoms in its early stages. These signs aren’t specific to kidney disease, so testing—typically blood creatinine/eGFR and a urine albumin test—is needed to determine whether the kidneys are actually affected.
Seek urgent medical care for blood in the urine with severe pain, very little/no urine, severe shortness of breath, confusion, or rapidly worsening swelling.
