What to do if…
you had recent abdominal surgery and new bloating with vomiting begins

Short answer

Treat new bloating with vomiting after recent abdominal surgery as urgent: contact your surgical ward/team now, or go to A&E if you can’t reach them quickly or you’re getting worse.

Do not do these things

  • Do not “wait it out” if vomiting and abdominal swelling are new, persistent, or worsening after discharge.
  • Do not keep eating, and do not force drinks “to stay strong” if you can’t keep them down.
  • Do not take extra doses of painkillers or anti-sickness medicines to avoid seeking care. Keep taking medicines exactly as prescribed, but don’t add extra doses/new OTC medicines without checking your discharge instructions or speaking to a clinician.
  • Do not drive yourself to hospital if you feel faint, weak, drowsy, or are actively vomiting.

What to do now

  1. Stop eating now. Avoid drinking large amounts. If your mouth is dry, take tiny sips just to moisten your mouth and stop if vomiting continues.
  2. Check your discharge paperwork immediately for:
    • the number for your ward / surgical assessment unit / on-call team, and
    • the “when to seek urgent help” section (many leaflets list painful bloated abdomen and nausea/vomiting as reasons to seek urgent advice).
  3. Call your surgical ward/team first using the number on your discharge letter. Say clearly:
    “Recent abdominal surgery; new bloating/distension and vomiting.”
  4. If you can’t reach a clinician quickly, go to A&E. If you’re unsure whether you need A&E, call NHS 111—but if you’re deteriorating, don’t wait for a call-back.
  5. Call 999 now (or ask someone to call) if any of these are happening:
    • severe or worsening abdominal pain, a hard/tender abdomen, or pain that won’t settle
    • you’re repeatedly vomiting or bringing up green (bile)
    • fever/rigors, new confusion, fainting, or you look/feel seriously unwell
    • trouble breathing or chest pain
    • vomiting blood / “coffee-ground” material, or black tarry stools
  6. Get ready to leave for urgent assessment. Put by the door:
    • your discharge letter and any operation paperwork
    • a list (or photo) of all medicines taken since discharge (including painkillers, anti-sickness meds, laxatives)
    • your allergies and emergency contact
    • if you have a stoma, note any major changes in output
  7. While waiting, write down: when vomiting started, how often, whether you can keep any fluids down, pain level, last time you passed wind/stool, temperature if you can check, and how much you’ve urinated.

What can wait

  • You do not need to work out the cause (obstruction vs ileus vs infection vs medication effects) right now.
  • You do not need to decide about diet changes, laxatives, or home remedies until you’ve been assessed.
  • You do not need to decide about complaints, blame, or “whether this should have happened.”

Important reassurance

It’s understandable to panic: vomiting plus new abdominal swelling after surgery feels alarming. Seeking urgent help is a reasonable, safety-first response, and many surgical discharge leaflets advise contacting the ward/team (or A&E) for these symptoms after discharge.

Scope note

These are first steps only to keep you safe and get you assessed. Treatment depends on the type of surgery, timing, and your exam/tests, so the priority is urgent medical review.

Important note

This guide is general information, not a diagnosis. After abdominal surgery, new bloating with vomiting can represent a complication that needs prompt assessment. If you feel you’re deteriorating or can’t get prompt advice, seek emergency care.
