The first 48 hours after surgery can feel like a bit of a blur, especially if you are still shaking off the effects of anaesthesia. Knowing roughly what to expect during this window can make the whole experience feel a lot less overwhelming.
Every procedure is different, and your surgical team will give you specific instructions for your situation. But there are some common patterns most Australians experience in the two days after an operation, covering everything from grogginess and pain to nausea and rest, and understanding them can help you feel more prepared and less anxious about what lies ahead.
Waking Up: The First Few Hours
Once your surgery is finished, you will be moved to a recovery area where nurses keep a close eye on you as the anaesthetic wears off.
Feeling Groggy and Confused
It is completely normal to feel drowsy, slow to think, or a little confused in the first hour or two. This usually settles as the anaesthetic clears from your system, though it can take a little longer after a long or complex operation. Having a support person nearby during this time can be reassuring, since you are likely to feel a little disoriented.
Going Home or Moving to a Ward
If you are having day surgery, you will typically be ready to leave hospital between two and six hours after your procedure, once you have recovered from the anaesthetic and received any medications to take home. If you are staying overnight, you will instead be transferred to a hospital ward.
Things to Avoid in the First 24 Hours
Because anaesthesia can affect your judgement and coordination for longer than you might expect, there are a few important things to hold off on.
- Do not drive a car or operate machinery
- Do not sign important legal or financial documents
- Do not drink alcohol or make major decisions
- Avoid caring for young children alone if possible
These restrictions are not about the surgery itself but about the lingering effects of anaesthesia on your reflexes and decision making, which can persist even once you feel mostly back to normal.
Managing Pain in the First Two Days
Pain is one of the most common concerns patients have, and it is genuinely at its most intense during this early window.
Research indicates that the most intense post-operative pain typically occurs within the first 24 hours and generally starts easing by 48 hours, though this varies depending on the type of surgery you have had, with movements like coughing or standing often triggering more discomfort than resting still.
- Take pain medication as prescribed, ideally before pain becomes severe
- Report pain honestly to nursing staff so it can be managed properly
- Expect some discomfort with movement, such as coughing or standing
Stronger pain relief, such as codeine-based medication, is commonly used in the first 24 hours after surgery, though your care team will tailor this to your specific procedure and needs.
Nausea and Vomiting After Surgery
Feeling queasy after an anaesthetic is extremely common, and it has a name of its own in medicine.
Postoperative nausea and vomiting, often shortened to PONV, is defined as nausea, retching or vomiting occurring within the first 24 to 48 hours after surgery, and it affects a significant proportion of surgical patients, particularly those at higher risk.
Nausea typically peaks within the first six hours and eases considerably by 24 to 48 hours for most people. Sipping water, eating light meals once you feel able to, and taking any prescribed anti-nausea medication can all help it settle. Moving slowly and avoiding sudden changes in position can also reduce how often it flares up.
What Your Body Is Doing Behind the Scenes
Even though you may feel tired or uncomfortable, your body is already hard at work repairing itself in these first two days.
Rest and sleep are especially important during this period, since your body relies on downtime to support wound healing and immune function. It is normal to sleep more than usual, and this is generally a good sign rather than something to worry about, even if it feels unusual compared to your normal routine.
- Stay hydrated with water and clear fluids unless told otherwise
- Follow any movement or activity restrictions from your surgical team
- Keep an eye on your surgical site for unusual redness, swelling or discharge
When to Be Concerned
Most symptoms in the first 48 hours are a normal part of recovery, but some signs are worth flagging to your care team promptly.
It is worth seeking medical advice if nausea is accompanied by severe pain, fever, an inability to keep fluids down, dizziness or signs of infection at the surgical site, rather than assuming these will resolve on their own.
If you are recovering at home, having a responsible adult with you for at least the first 24 hours is generally recommended, both for practical support and to help you notice if something does not seem right. This is especially important overnight, when it can be harder to judge whether a symptom is worth acting on.
Conclusion
The first 48 hours after surgery usually involve grogginess, some pain, and possibly a bout of nausea, all of which tend to ease as time passes. Knowing this pattern in advance can help you feel more settled and less alarmed if you experience any of it yourself.
If anything feels unusual or more severe than expected during your recovery, do not hesitate to contact your surgical team or hospital for guidance.

FAQs
1. Is it normal to feel confused right after surgery?
Yes. Feeling groggy, slow to think or a little confused in the first hour or two after anaesthesia is common and usually settles fairly quickly as the medication clears your system, particularly with support from a friend or family member nearby.
2. How long does pain usually last after surgery?
Pain is typically most intense in the first 24 hours and generally begins easing by 48 hours, though this varies depending on the procedure and how extensive it was. Taking prescribed pain relief on schedule, rather than waiting for pain to build, helps keep it manageable.
3. Is it normal to feel sick after anaesthesia?
Yes. Postoperative nausea and vomiting is common and usually peaks within the first six hours, easing over the following one to two days for most patients, with anti-nausea medication available if needed.
4. When should I be worried about symptoms after surgery?
Contact your care team if you experience severe pain, fever, persistent vomiting, dizziness or signs of infection at the surgical site, rather than waiting to see if it passes on its own.
5. Do I need someone with me after I leave hospital?
Yes, generally. Having a responsible adult with you for the first 24 hours after surgery is commonly recommended for both support and safety while the effects of anaesthesia fully wear off from your system.
