Signs and symptoms of chronic kidney disease develop over time if kidney damage progresses slowly. Signs and symptoms of kidney disease may include:
- Loss of appetite
- Fatigue and weakness
- Sleep problems
- Changes in urine output
- Decreased mental sharpness
- Muscle twitches and cramps
- Swelling of feet and ankles
- Persistent itching
- Chest pain, if fluid builds up around the lining of the heart
- Shortness of breath, if fluid builds up in the lungs
- High blood pressure (hypertension) that's difficult to control
Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. And because your kidneys are highly adaptable and able to compensate for lost function, signs and symptoms may not appear until irreversible damage has occurred.
When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms of kidney disease.
If you have a medical condition that increases your risk of chronic kidney disease, your doctor is likely to monitor your blood pressure and kidney function with urine and blood tests during regular office visits. Ask your doctor whether these tests are necessary for you.
