- ✓Getting up to urinate at night
Later signs
- ✓Persistent leg swelling
- ✓Poor appetite, nausea, a metallic taste
- ✓Itching and dry skin
- ✓Shortness of breath from fluid
Red flags — act now
Very little or no urine, blood in urine, severe flank pain, or sudden breathlessness need urgent medical attention.
Frequently Asked Questions
Where is kidney pain felt?
Usually in the back, just below the ribs, on one or both sides — but many kidney diseases cause no pain at all.
Does foamy urine always mean kidney disease?
Not always, but persistent foam can signal protein in urine and should be checked.
