Symptoms

Early in chronic kidney disease, you might have no signs or symptoms. As chronic kidney disease progresses to end-stage renal disease, signs and symptoms might include:

• Nausea
• Vomiting
• Loss of appetite
• Fatigue and weakness
• Changes in how much you urinate
• Chest pain, if fluid builds up around the lining of the heart
• Shortness of breath, if fluid builds up in the lungs
• Swelling of feet and ankles
• High blood pressure (hypertension) that's difficult to control
• Headaches
• Difficulty sleeping
• Decreased mental sharpness
• Muscle twitches and cramps
• Persistent itching
• Metallic taste

Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. Because your kidneys can make up for lost function, signs and symptoms might not appear until irreversible damage has occurred.

When to seek care

Make an appointment with your health care provider if you have signs or symptoms of kidney disease.

If you have a medical condition that increases your risk of kidney disease, your care provider is likely to monitor your kidney function with urine and blood tests and your blood pressure during regular office visits. Ask your provider whether these tests are necessary for you.
