Getting sick before surgery can be frustrating, especially if you've spent weeks preparing for your procedure.
Many patients wonder whether a cold, sore throat, fever, or other illness means their surgery will be canceled. The answer depends on the type of illness, your symptoms, and the surgery you're having.
If you become sick before surgery, the most important step is to let your healthcare team know as soon as possible. They can help determine the safest plan.
Quick Summary
- Contact your surgeon or surgical facility if you become sick before surgery.
- Do not assume your surgery will automatically be canceled.
- Fever, flu, COVID-19, or worsening respiratory symptoms may require your team to reassess your surgery.
- Mild symptoms do not always prevent surgery.
- Early communication helps avoid last-minute surprises.
Why Does Being Sick Matter?
Even a minor illness can affect anesthesia or recovery.
Your healthcare team wants to make sure:
- Your lungs are healthy enough for anesthesia.
- Your infection will not increase surgical risks.
- Your body is ready to recover after surgery.
Sometimes delaying surgery is the safest option—but many illnesses do not automatically mean cancellation.
Which Symptoms Should I Report?
Call your surgical team if you develop:
- Fever
- Chills
- Persistent cough
- Shortness of breath
- Flu-like symptoms
- COVID-19
- Vomiting or diarrhea
- A new infection
- A rash near the surgical site
It is always better to ask than to guess.
What About a Mild Cold?
Many patients have mild congestion or a runny nose before surgery.
Depending on your symptoms and overall health, surgery may still be able to proceed.
Your anesthesia team and surgeon will determine whether it is safe.
Should I Wait Until Surgery Day?
No.
If you become sick several days before surgery, contact your healthcare team as soon as possible.
Early communication gives them time to evaluate your situation and discuss next steps.
Can My Surgery Be Rescheduled?
Sometimes.
If your illness could increase the risks of anesthesia or surgery, your healthcare team may recommend waiting until you've recovered.
Although disappointing, delaying surgery can sometimes be the safest decision.
How Can I Reduce My Risk of Getting Sick?
In the days leading up to surgery:
- Wash your hands frequently.
- Avoid close contact with people who are ill.
- Get enough rest.
- Stay hydrated.
- Follow your Prepare for Surgery Checklist to stay organized and reduce last-minute stress.
