Kidney disease is often silent early on, which is why it is easy to miss. Knowing the signs that do appear can help you get tested sooner.
Early signs
- Foamy urine
- Tiredness
- Swelling around the eyes or ankles
- Waking at night to pass urine
Later signs
- Persistent leg swelling
- Poor appetite, nausea or a metallic taste
- Itching
- Shortness of breath from fluid
Red flags
Little or no urine, blood in the urine, severe flank pain, or sudden breathlessness need prompt attention.
Frequently asked questions
Where is kidney pain felt?
In the flank, below the ribs. Chronic kidney disease itself is usually painless.
Does foamy urine always mean kidney disease?
No, but persistent foam should be checked.
