Preparing for Surgery: A Checklist

Hearing that you need surgery can stir up a mix of relief, worry and a long list of unanswered questions. That is completely normal. The good news is that much of what shapes a smooth operation and recovery happens before you ever reach the operating room. Preparation gives you a sense of control, and research consistently links well-prepared patients with fewer complications and more comfortable recoveries.

Why preparation matters

Surgery places temporary stress on the body. Anesthesia, tissue healing and reduced activity all ask your heart, lungs, immune system and metabolism to work harder. Studies of enhanced recovery programs have found that patients who are informed, well nourished, and physically ready tend to leave the hospital sooner and report less pain and anxiety. Preparation will not remove every risk, but it can meaningfully tilt the odds in your favor.

Preparation affects everyone having a procedure, whether it is minor and outpatient or a major operation requiring a hospital stay. Older adults, people with chronic conditions such as diabetes, heart disease or lung disease, and those who smoke have the most to gain from careful planning.

Weeks before: understand the plan

Start by making sure you truly understand what is being done and why. Good questions are not a burden to your care team; they are part of informed consent.

  • What is the exact procedure, and what are the alternatives, including not operating?
  • What are the common risks and the expected benefits for someone in my situation?
  • What type of anesthesia will be used, and who will be managing it?
  • How long is the typical recovery, and what limits will I have on work, driving and lifting?
  • Who do I call if I have a concern before or after the procedure?

Review medications and your health history

Bring a complete list of everything you take: prescriptions, over-the-counter medicines, vitamins and herbal supplements. Some products affect bleeding, blood pressure, blood sugar or how anesthesia works. Blood thinners, anti-inflammatory pain relievers, certain diabetes medicines and supplements such as fish oil or ginkgo are common examples that may need to be adjusted.

Never stop or change a prescription on your own. Ask your surgeon or physician exactly which medicines to continue, which to pause, and when to restart them. Also mention any allergies, past reactions to anesthesia, and any personal or family history of bleeding or clotting problems.

Preparation will not remove every risk, but it can meaningfully tilt the odds in your favor.

Get your body ready

Evidence supports a few simple steps. Quitting smoking, ideally several weeks before surgery, lowers the risk of wound and breathing problems. Limiting alcohol, eating balanced meals with enough protein, and staying gently active can support healing. If you have diabetes, good blood sugar control helps reduce infection risk. Walking regularly or doing prescribed exercises before surgery, sometimes called prehabilitation, may speed return to normal activity afterward.

The day-before and day-of checklist

  • Follow fasting instructions exactly. Eating or drinking when told not to can force a delay or cancellation.
  • Shower as directed and remove nail polish, jewelry, contact lenses and piercings.
  • Pack your ID, insurance information, medication list and comfortable loose clothing.
  • Arrange a responsible adult to drive you home and stay with you for the first 24 hours.
  • Confirm your arrival time and the facility location.
  • Sign and review consent paperwork, and bring any advance directive you have.

Set up your home for recovery

Your recovery begins the moment surgery ends, so prepare your space ahead of time. Stock easy meals, place frequently used items at waist height, and set up a comfortable resting area with extra pillows. Remove trip hazards such as loose rugs, and consider a shower chair or grab bars if mobility will be limited. Fill any prescriptions in advance and ask how to manage pain safely, including how to take medicines on schedule and what side effects to expect.

Finally, look after your emotional health. Nervousness is common. Talking with loved ones, practicing slow breathing, and asking your team to walk you through what the day will look like can all ease anxiety.
