What Happens at a Pre-Op Appointment Before Surgery

A pre-op appointment is a medical visit before your surgery where your doctor checks that you're healthy enough for the procedure and reviews what to expect.

The appointment usually happens one to two weeks before your scheduled surgery, though timing varies depending on the type of procedure and your medical history. During this visit, your surgical team — typically your surgeon, an anesthesiologist or nurse anesthetist, and nursing staff — will examine you, review your medical records, and make sure you understand the risks and what happens on surgery day. They're checking that no new health problems have developed since you were scheduled, that your current medications won't interfere with surgery, and that you're mentally and physically ready to proceed.

This is also your chance to ask questions and raise any concerns. If something doesn't feel right or you've developed new symptoms, tell your doctor now rather than waiting until you're in the operating room. The pre-op appointment is designed to catch problems early and give you time to prepare.

Key Takeaways

• Your pre-op appointment usually happens one to two weeks before surgery and includes a physical exam, blood work, and a review of your medical history.
• You'll meet with your surgeon and the anesthesiologist (or their team) to discuss the procedure, anesthesia options, and any risks specific to you.
• Bring a list of all medications and supplements you take, including over-the-counter drugs and herbal products, because some must be stopped before surgery.
• You'll receive written instructions about fasting, when to stop taking certain medications, what to wear, and what to bring on surgery day.
• If you develop a fever, infection, or new health problem between your pre-op appointment and surgery, contact your surgeon's office immediately.

What the doctor will check during your visit

Your surgeon will review why you're having surgery, what the procedure involves, and what results you can realistically expect. They'll examine the area being operated on and ask about your symptoms and how they've affected your daily life. This is a good time to ask about scarring, recovery time, and whether you'll need follow-up procedures.

The anesthesiologist or nurse anesthetist will ask detailed questions about your medical history, including past surgeries, allergies, and any bad reactions to anesthesia you or your family members have had. They'll want to know about sleep apnea, heart problems, lung disease, or any condition that affects how your body handles anesthesia. They'll also ask about alcohol use, because heavy drinking can change how anesthesia works. Be honest — this information is confidential and directly affects your safety.

A nurse will take your blood pressure, temperature, heart rate, and oxygen level. You may have blood work done (usually a complete blood count and metabolic panel) and possibly an EKG or chest X-ray, depending on your age, the type of surgery, and your health history. These tests catch problems like anemia, infection, or heart rhythm issues that could complicate surgery.

Medications and supplements to discuss

Bring a complete list of everything you take — prescription medications, over-the-counter drugs, vitamins, and herbal supplements. Some medications thin your blood (like aspirin, ibuprofen, or warfarin) and must be stopped days or weeks before surgery to prevent excessive bleeding. Others, like blood pressure or heart medications, may need to be continued right up to surgery or adjusted. Your surgeon will tell you exactly which to stop and when.

Don't stop taking any medication on your own before your pre-op appointment. Even if you've read online that you should stop something, wait for your doctor's instruction — stopping the wrong medication can be more dangerous than the surgery itself. If you're unsure whether something counts as a medication (some people don't think of vitamins or herbal products that way), mention it anyway.

Pre-op instructions you'll receive in writing

Before you leave, you'll get a printed sheet with specific instructions for surgery day. These typically include when to stop eating and drinking (usually midnight the night before, but this varies), what time to arrive at the surgical facility, what to wear, and what to bring. Follow these instructions exactly — eating or drinking when you're supposed to fast can cause serious complications with anesthesia.

The instructions will also tell you which medications to take the morning of surgery and which to skip. Some people need to take their blood pressure or heart medication with a small sip of water; others need to skip everything. You'll be told whether to shower the night before or morning of surgery, and whether to use a special antimicrobial soap. You'll learn what to do with jewelry, glasses, contact lenses, dentures, or hearing aids — some facilities let you keep them until you're in the pre-op area, others don't.

You'll also receive information about what to expect after surgery: how long recovery takes, what pain or discomfort is normal, when you can return to work or exercise, and what signs of infection or complications mean you should call your surgeon. Read this carefully and ask questions if anything is unclear.

What to bring and how to prepare

Bring your insurance card, photo ID, and any paperwork your surgeon's office sent you. Wear comfortable, loose-fitting clothes that are easy to remove — you'll change into a surgical gown, but you want to be able to get dressed quickly afterward. Don't wear makeup, nail polish, or jewelry, because the surgical team needs to see your skin color and monitor your oxygen levels through a pulse oximeter on your finger. Remove contact lenses and wear glasses instead if you need them for vision.

Arrange for someone to drive you home. Even if you feel alert after surgery, anesthesia impairs your judgment and reaction time for hours afterward, and most surgical facilities won't discharge you without a responsible adult to drive. Plan for that person to stay with you for at least the first 24 hours, because you shouldn't operate machinery, make important decisions, or be alone while the anesthesia wears off.

The night before surgery, eat a normal dinner (unless your instructions say otherwise), get a good night's sleep, and shower or bathe. Set an alarm so you have time to get ready without rushing. Eat nothing after midnight unless your surgeon says otherwise — this includes water, gum, mints, and coffee. An empty stomach prevents vomiting during anesthesia, which can be dangerous.

When to contact your surgeon before surgery day

If you develop a fever, cough, sore throat, or signs of infection between your pre-op appointment and surgery, call your surgeon's office right away. A fever or active infection usually means surgery will be postponed, because operating on an infected or ill body increases complications. Don't assume it's minor — let your surgeon decide.

Also call if you have chest pain, shortness of breath, or severe headache; if you start a new medication; if you have an allergic reaction to anything; or if you're injured or have an accident. If you're a woman and you get your period right before surgery, mention it when you call — your surgeon may want to reschedule depending on the type of procedure.

If you have questions about your pre-op instructions or anything you don't understand, call before surgery day rather than showing up confused on the morning of the procedure. Your surgeon's office expects these calls and would rather clarify now than have you make a mistake that delays surgery.

What happens if you don't attend your pre-op appointment

Skipping your pre-op appointment usually means your surgery will be cancelled. Surgical facilities need the medical clearance and anesthesia assessment documented before they can proceed. If you can't make the scheduled appointment, call your surgeon's office immediately to reschedule — don't just miss it and hope they'll fit you in another time.

If you're rescheduling close to your surgery date, ask whether you need a new pre-op appointment or whether your previous one is still valid. Some offices will clear you based on an earlier visit if only a few days have passed and nothing has changed; others require a new appointment. Don't assume — ask.

Frequently Asked Questions

Can I take my regular medications the morning of surgery?

Some yes, some no — it depends on the medication and your surgery. Your pre-op instructions will specify which medications to take with a small sip of water and which to skip. If your instructions aren't clear, call your surgeon's office the day before surgery to confirm. Never guess about this.

What if I'm nervous about anesthesia?

Tell your anesthesiologist at your pre-op appointment. They can explain what type of anesthesia you'll receive, how it works, and what you'll experience. They can also discuss your specific concerns — whether it's fear of not waking up, nausea afterward, or something else — and may adjust your anesthesia plan based on your needs.

Do I need someone to stay with me after surgery?

Yes. Most surgical facilities require a responsible adult to pick you up and stay with you for at least 24 hours because anesthesia affects your judgment and coordination. If you don't have someone available, tell your surgeon's office before surgery day — they may be able to suggest resources or reschedule.

What if I eat or drink before surgery by accident?

Tell your surgical team immediately when you arrive. They may postpone surgery to reduce the risk of vomiting during anesthesia, or they may proceed with extra precautions. Don't hide it — your safety depends on them knowing what's in your stomach.

How long does a pre-op appointment usually take?

Plan for one to two hours. You'll check in, wait to be called, have your vital signs taken, meet with your surgeon and anesthesiologist, have blood work or other tests done, and receive your written instructions. Bring something to read or do while you wait.
