Swelling (Edema)
Swelling in the feet, ankles or face can have many causes — the kidneys are an important one to check properly.
Medically reviewed by the RIIMS nephrology team · Last updated: June 2026
When does swelling point to the kidneys?
When kidneys cannot remove enough salt and water, or when protein is leaking into urine, fluid collects in the tissues — typically feet and ankles by evening, or around the eyes in the morning. Heart, liver and vein problems can also cause swelling, so the right tests matter: kidney function, urine protein, and a careful history.
Symptoms to watch for
- Swollen feet or ankles, worse by evening
- Puffiness around eyes in the morning
- Tight rings or shoes
- Sudden weight gain
- Reduced or foamy urine
- Breathlessness when lying flat (seek care promptly)
When to consult a kidney doctor
Swelling that persists, recurs, or comes with foamy urine, high BP or breathlessness should be evaluated without delay.
