How to Prepare for Surgery: A Practical Guide for First-Time Patients

Being told you need surgery, even when it’s planned, even when it’s straightforward brings a certain kind of anxiety with it. There’s the procedure itself to think about. The anaesthesia. What to eat beforehand, what to bring, what happens after. And underneath all of that, a general feeling of not quite knowing what you’re supposed to be doing in the days leading up to it.

That uncertainty is normal. Most first-time surgical patients feel it. And a lot of it comes down to simply not having been through this before, not knowing what the process looks like from the patient’s side.

This guide is about changing that. A practical, straightforward walkthrough of what to expect and how to prepare, so you go into surgery feeling informed rather than anxious.

Start With Your Pre-Operative Consultation

Everything begins here. Before any surgery, you’ll have a pre-operative assessment, sometimes called a pre-op, where the surgical and anaesthesia team reviews your health, confirms the plan, and identifies anything that needs attention before the procedure.

This is the time to be completely open about your medical history. Current medications, supplements, allergies, previous surgeries, existing health conditions- all of it. Nothing is too minor to mention. Something that seems irrelevant, like a herbal supplement you’ve been taking, can have a real impact on anaesthesia or bleeding. Your team needs the full picture.

It’s also the time to ask questions. Write them down before you go in, because sitting in a consultation room, things you meant to ask have a way of slipping away. No question is too basic. Understanding what’s happening to your body is entirely reasonable, and any surgical team worth their salt will take the time to answer properly.

Medications What to Continue and What to Stop

This is one of the most important practical details to sort out well in advance.

Some medications need to be paused before surgery. Blood thinners aspirin, warfarin, clopidogrel, are common ones, as they affect how the blood clots during and after the procedure. Certain diabetes medications, particularly metformin, are often paused around the time of surgery too. Herbal supplements like fish oil, ginger, and ginkgo can also affect bleeding.

Other medications need to continue right up to the day of surgery, some blood pressure medications and seizure medications fall into this category.

The key point is this: don’t make any decisions about medications on your own. Your surgical team will give you specific instructions about what to stop, what to continue, and when. Follow those instructions precisely, and if anything is unclear, call and ask before the day arrives.

Fasting Before Surgery Why It Matters

Almost every surgical patient is told not to eat or drink before their procedure. The standard guideline is nothing to eat for at least six to eight hours beforehand, and nothing to drink, including water for at least two hours before. The exact timing your team gives you may differ slightly, and their instructions take precedence.

The reason for this isn’t arbitrary. When anaesthesia is administered, the body’s normal reflexes including the gag reflex, are temporarily suppressed. If there’s food or liquid in the stomach, there’s a risk of it being inhaled into the lungs during the procedure. This is called aspiration, and it’s a serious complication. Fasting eliminates that risk.

It can feel uncomfortable, especially if the procedure is scheduled later in the day. But it’s non-negotiable and if you’ve eaten when you weren’t supposed to, tell your team before the procedure begins rather than staying quiet about it.

The Week Before Surgery

A few things worth doing in the days leading up to the procedure:

Avoid alcohol for at least 48 hours beforehand, ideally longer. Alcohol affects how the body responds to anaesthesia and can increase bleeding risk.

Don’t smoke in the days before surgery if possible. Smoking affects lung function and the body’s ability to heal afterward. Even a few days without smoking makes a measurable difference to recovery.

Stay hydrated and eat well in the days before your fast begins. Going into surgery in a good nutritional state helps recovery. This isn’t the time to crash diet or skip meals.

Get your home ready for recovery. Think practically about what you’ll need when you come back. If you’re going to be limited in movement for a few days, consider where you’ll rest, what you’ll eat, and whether you’ll need help with daily tasks. Having this arranged in advance takes significant pressure off the recovery period.

Arrange transport. You will not be able to drive yourself home after surgery. Even if the procedure is minor and you feel fine afterward, the effects of anaesthesia mean driving isn’t safe for at least 24 hours. Make sure someone is coming to take you home and ideally, staying with you for the first night.

What to Bring on the Day

Keep it simple. Most hospitals and clinics have lockers or limited storage, so overpacking isn’t helpful. What you’ll typically need:

• Your identification and any insurance or hospital documents
• A list of your current medications
• Comfortable, loose-fitting clothing easy to put on and take off, particularly if the surgical site is in an area that tight clothing would press against
• Personal hygiene basics if you’re staying overnight
• A phone and charger
• Any items that genuinely help you feel calm a book, earphones, something familiar

Leave valuables at home. Jewellery, watches, and piercings generally need to be removed before surgery anyway.

On the Day of Surgery

Arrive at the time you’ve been given not earlier than necessary, but certainly not late. The surgical team works to a schedule, and delays at the start create a ripple effect.

You’ll go through a check-in process where your identity, procedure, and consent are confirmed. The anaesthetist will speak with you before the procedure. This is another opportunity to flag anything you haven’t already mentioned allergies, concerns about anaesthesia, anything that’s come up since your pre-op.

It’s completely normal to feel nervous. Tell the team how you’re feeling. They’ve seen it many times, and there’s no expectation that patients walk in entirely calm. Small things explaining what’s happening at each step, answering questions, a quiet and reassuring tone, make a real difference, and any good surgical team will provide that.

What Happens After The Recovery Room

When the procedure is done, you’ll be moved to a recovery area where nursing staff monitor you as the anaesthesia wears off. This is a quiet, controlled environment. You may feel groggy, disoriented, or emotional, all of this is entirely normal as the anaesthesia clears.

Pain is managed from the start, you won’t be left uncomfortable while waiting for medication to kick in. Let the staff know how you’re feeling, including how your pain levels are, so they can respond accordingly.

Once you’re stable and alert enough, you’ll be moved to a ward if staying overnight, or prepared for discharge if it’s a day procedure.

Going Home and the Early Recovery Period

Discharge instructions matter. Read them carefully or have someone with you who can take notes if you’re still feeling the effects of anaesthesia when you’re being discharged.

You’ll typically be told:

• When you can eat and drink normally again
• What medications to take and when
• What to watch for in terms of warning signs fever, increasing pain, redness around the wound, unusual discharge
• When to come back for a follow-up
• How long to avoid driving, heavy lifting, and strenuous activity

The first 24 to 48 hours after surgery are usually the most uncomfortable. Rest properly during this period the temptation to push through and get back to normal quickly is understandable, but recovery that’s rushed often takes longer overall.

Signs That Need Prompt Attention After Surgery

Most post-operative discomfort is expected and manageable. But certain signs mean you should contact your surgical team or go to the emergency department without delay:

• Fever above 38.5°C
• Increasing rather than decreasing pain at the surgical site
• Redness, swelling, or discharge from the wound
• Difficulty breathing or chest pain
• Unusual swelling in the legs
• Vomiting that won’t settle

These don’t necessarily mean something has gone seriously wrong, but they need to be assessed rather than waited out at home.

Final Thoughts

Surgery is a significant event, but it doesn’t have to feel overwhelming. The more you understand about what’s coming, what to do beforehand, what to expect on the day, and what recovery looks like, the more in control you’ll feel going in.

Preparation isn’t just practical. It genuinely affects outcomes. Patients who go into surgery well-rested, properly fasted, with medications managed correctly and a clear recovery plan at home, tend to recover more smoothly than those who haven’t had the chance to prepare properly.

Our team takes the time to walk every patient through the process before their procedure, answering questions, addressing concerns, and making sure nothing important is left unclear. If you’ve been scheduled for surgery and have questions about what to do in the lead-up, don’t hesitate to reach out or come in. Going in prepared makes the whole experience easier for everyone.
