What to do if…
you have new abdominal bloating and vomiting after recent surgery
Short answer
New abdominal bloating or swelling with vomiting after abdominal surgery can be a possible serious complication. Call your surgeon’s on-call line now, and go to the emergency department if you cannot reach them promptly or symptoms are worsening.
Do not do these things
- Do not keep eating while vomiting is continuing.
- Do not force large amounts of fluid if it makes you vomit again.
- Do not take extra opioid pain medicine to try to get through it.
- Do not take anti-nausea medicine in higher-than-prescribed doses to avoid being assessed.
- Do not start laxatives, enemas, or home remedies unless a clinician who knows your surgery tells you to.
- Do not drive yourself if you feel weak, dizzy, faint, drowsy, confused, or are actively vomiting.
What to do now
- Stop eating for now. If your mouth is dry, take tiny sips only to moisten your mouth, and stop if vomiting continues.
- Call your surgeon’s on-call number immediately. It is often on your discharge papers, patient portal, prescription paperwork, or hospital discharge instructions.
- Start the call with: “I had recent abdominal surgery. I now have new abdominal bloating or distension and vomiting.”
- If you cannot reach a clinician promptly, go to the emergency department now. Vomiting with new abdominal distension after surgery can need urgent assessment.
- Call 911 now if you have severe or worsening abdominal pain, a hard or very tender abdomen, fainting, confusion, chest pain, trouble breathing, vomiting blood, black coffee-ground vomit, black tarry stool, or you feel too unwell to travel safely.
- Tell the clinician or emergency team whether you can pass gas or stool, when you last had a bowel movement, whether vomit is green, how many times you have vomited, whether you can keep tiny sips down, and whether you are urinating much less than usual.
- Bring or show your discharge instructions, operative report if you have it, medication list, allergies, surgeon’s name, hospital name, and photos of medication bottles. Include opioids, stool softeners, laxatives, and anti-nausea medicines.
- If you have a stoma, tell them whether the output has stopped, sharply increased, changed colour, or changed from your usual pattern.
What can wait
- You do not need to decide whether this is normal recovery, ileus, bowel obstruction, constipation, gas pain, infection, or a medication effect right now.
- You do not need to decide on diet changes, laxatives, enemas, or home treatment before you are assessed.
- You do not need to sort out paperwork, insurance details, follow-up scheduling, or non-urgent messages before getting medical help.
Important reassurance
It is reasonable to feel alarmed. After abdominal surgery, new distension with vomiting is a pattern clinicians usually want to assess quickly, and getting checked is the safer choice even if the cause turns out to be treatable.
Scope note
These are first steps only. The right next care depends on your surgery type, timing, exam, medications, and any tests, so later decisions may need your surgical team or emergency clinicians.
Important note
This is general information, not medical advice, a diagnosis, or a substitute for professional medical care. If symptoms are worsening, you cannot keep fluids down, or you cannot reach your surgical team promptly, seek emergency care.
