What to do if…
you develop facial or hand swelling with reduced or frothy urine

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Ask for an urgent medical assessment now because swelling together with reduced or frothy urine can need prompt checks. Call 999 if you are struggling to breathe, your lips, mouth, tongue or throat suddenly swell, you cannot swallow normally, or you become very drowsy, confused, faint or unresponsive.

Do not do these things

  • Do not wait several days to see whether the combination settles by itself.
  • Do not rapidly drink a large amount of water or impose a strict fluid restriction yourself.
  • Do not take extra water tablets or medicines prescribed for someone else.
  • Do not start new over-the-counter medicines or supplements before checking with a pharmacist or clinician.
  • Do not stop or change prescribed medicines without urgent professional advice.
  • Do not drive yourself if you are breathless, dizzy, drowsy or confused.
  • Do not leave rings, watches or other tight items on a swelling hand.

What to do now

  1. Call 999 if you are struggling to breathe, breathing very fast, choking or gasping, your throat feels tight, your lips, mouth, tongue or throat suddenly swell, your skin or lips turn blue, grey or unusually pale, or you become confused, very drowsy, faint or unresponsive.
  2. If you are pregnant or gave birth within the last few weeks, contact your maternity unit immediately. Mention any sudden facial or hand swelling, severe headache, vision changes, pain below the ribs, vomiting or feeling very unwell.
  3. Otherwise, ask your GP practice for an urgent appointment. If it is closed or cannot direct you promptly, call 111 in England, NHS 24 on 111 in Scotland, or NHS 111 Wales on 111. In Northern Ireland, contact your local GP out-of-hours service when your practice is closed.
  4. Say clearly that you have developed facial or hand swelling together with reduced or frothy urine. Give the approximate time each symptom began and whether it is worsening.
  5. Note when you last passed urine, roughly how much you have passed compared with normal, and whether it looks dark, bloody or persistently frothy. Do not delay contacting medical help to gather this information.
  6. Gather your medicine packets or medication list, including prescription medicines, painkillers, supplements and anything started recently.
  7. Tell the clinician about pregnancy, recent childbirth, kidney, heart or liver problems, diabetes, high blood pressure, a recent infection, vomiting, diarrhoea or surgery.
  8. Remove rings, watches and tight clothing from swollen hands. Ask someone to stay with you or help you travel if you feel unwell.
  9. Follow any fluid limit already set by your medical team. Otherwise, avoid trying to correct the problem by rapidly increasing or severely reducing how much you drink before receiving advice.

What can wait

You do not need to identify the cause, decide whether you have kidney failure, change your long-term diet or create a detailed fluid plan now. Routine appointments, long-term treatment decisions and attempts to measure the exact amount of froth can wait until you have been assessed.

Important reassurance

This combination does not confirm kidney failure or any one condition. Several problems can cause swelling or urine changes, and a clinician can assess you by checking factors such as your blood pressure, medicines, blood and urine.

Scope note

This guide covers immediate first steps only. Later decisions may require assessment by a GP, maternity team, urgent-care clinician, hospital team or kidney specialist.

Important note

This is general health information, not a diagnosis or a substitute for medical advice. Use 999 for a life-threatening emergency and seek urgent professional assessment for the symptoms described here.
