When Crohn's disease or ulcerative colitis symptoms worsen, many people freeze on one question: do I call the GI nurse line, go to urgent care, or head to the emergency room? There is no perfect flowchart for every body, but a clear decision tree reduces panic and helps you act sooner when it matters. This article is educational and aligned with common Crohn's & Colitis Foundation (CCF) patient education themes. It is not a substitute for emergency medical care.
Start with your clinic's after-hours plan
Before a crisis, save your gastroenterology office number, after-hours nurse line, and any portal instructions in your phone. Many IBD centers prefer a nurse triage call for flares that are uncomfortable but not immediately life-threatening. The nurse can advise whether same-day clinic, labs, steroids, imaging, or the ER is appropriate for your history.
- Keep a one-page medication list and diagnosis card in your wallet or phone notes
- Know whether you have fistulas, strictures, ostomy, recent surgery, or immunosuppression
- Track stool frequency, blood, fever, pain location, and food or fluid intake for 24 hours
Call the GI nurse line first when
Use the nurse line or portal for flares that feel familiar, are escalating over hours to a day or two, and do not include the emergency red flags below. Examples include more frequent stools than your baseline, mild to moderate abdominal pain you can still walk with, limited rectal bleeding that is not pouring, fatigue without fainting, and questions about holding or adjusting medicines. The nurse may arrange urgent clinic, stool studies, bloodwork, or a short steroid bridge if your clinician agrees.
Pair this with our practical flare plan in the first 48 hours of a flare: rest, hydration, simplified meals your team has approved, and clear notes for the call.
Consider urgent care when
Urgent care can help with problems that need same-day evaluation but are not classic IBD emergencies, such as a urinary infection, a minor injury, dehydration that still allows you to drink, or fever without severe abdominal findings. If you are immunosuppressed, tell staff immediately. Urgent care is not ideal for heavy GI bleeding, severe abdominal pain with rigidity, or suspected bowel obstruction. When in doubt, call your GI nurse line on the way so they can redirect you.
Go to the ER when
Emergency evaluation is for symptoms that can threaten organs, blood volume, or the bowel itself. Seek ER care for:
- Heavy rectal bleeding, black stools with dizziness, or bleeding that soaks multiple pads in a short time
- Severe abdominal pain with vomiting, inability to pass stool or gas, or a rigid, tender belly
- High fever with shaking chills while on biologics, steroids, or immunosuppressants
- Fainting, confusion, chest pain, shortness of breath, or inability to keep any fluids down
- New severe swelling or pain in one leg, or sudden severe headache with neurologic changes

What to bring and say in the ER
State that you have IBD, name your medications (including last biologic or steroid dose), and list surgeries or complications. Ask the team to contact your gastroenterologist. Bring prior discharge summaries if you have them. Do not stop prescribed IBD medicines unless a clinician tells you to.
After the visit
Whether you used the nurse line, urgent care, or the ER, schedule follow-up with your IBD clinician. Update your flare log, note what helped, and review whether your maintenance plan needs adjustment. Education resources from CCF and your care team work best together; neither replaces the other in a true emergency.
