What Are the Biggest Mistakes to Avoid on Surgery Day?

After weeks of preparing for surgery, the day finally arrives. While your surgical team will guide you through the process, there are a few common mistakes that can delay your procedure, increase stress, or even cause your surgery to be postponed.

The good news is that most of these mistakes are easy to avoid with a little planning.

Quick Summary

The biggest surgery day mistakes include:

Eating or Drinking After Your Fasting Time

One of the most common reasons surgeries are delayed or canceled is accidentally eating or drinking after your instructed cutoff time.

Even coffee, gum, candy, or a small sip of water may not be allowed depending on your instructions.

If you're unsure about your fasting instructions, it's safest to call your surgical team before eating or drinking anything.

Arriving Late

Most patients are asked to arrive one to two hours before their scheduled procedure.

This extra time allows your care team to:

Running late can create unnecessary stress and, in some cases, require your surgery to be rescheduled.

Plan extra travel time and leave earlier than you think you'll need.

Wearing Makeup, Jewelry, or Nail Polish

Many surgery centers ask patients to remove:

These instructions aren't simply for appearance—they help your care team monitor you safely during surgery and reduce the risk of complications.

If your surgical team gives you instructions that differ from general recommendations, always follow their guidance.

Taking the Wrong Medications

Some medications should be continued before surgery, while others need to be stopped days beforehand.

Taking—or skipping—the wrong medication can affect bleeding, blood pressure, blood sugar, or anesthesia.

If you're unsure what to take, contact your surgeon's office rather than guessing.

Not Having a Ride Home

Bringing Valuables

Leave valuables at home whenever possible, including:

Bring only what you'll actually need for your procedure.

Ignoring Your Surgical Team's Instructions

Every surgery is different.

General advice can be helpful, but your surgeon's instructions should always take priority.

If something you've read online conflicts with what your surgical team has told you, follow their instructions or contact them for clarification.
