Kidney Swelling (Edema) Treatment
Swelling in the feet, ankles or face can have many causes — the kidneys are an important one to check properly.

When does swelling point to the kidneys?
When kidneys cannot clear enough salt and water, or when protein is leaking into urine, fluid collects in the tissues — typically the feet and ankles by evening, or around the eyes in the morning. But swelling is not always the kidneys: the heart, liver, veins and some medicines can cause it too, so the right tests matter. A proper work-up — creatinine, eGFR, urine protein and a careful history — reveals the true cause instead of guessing.
Symptoms to watch for
- Swollen feet or ankles, worse by evening
- Puffiness around the eyes in the morning
- Tight rings or shoes
- Sudden weight gain from fluid
- Reduced or foamy urine
- Breathlessness lying flat — seek care promptly
When to consult a kidney doctor
Swelling that persists or recurs, or comes with foamy urine, high BP or breathlessness, should be evaluated without delay. Rapidly increasing swelling with breathlessness needs urgent care.
