Preparing for Surgery: A Complete Patient Guide

1. Understand Why You Need Surgery

Before agreeing to an operation, make sure you understand why your doctor has recommended it.

Ask your surgeon:

• What condition is being treated?
• Why is surgery being recommended?
• Are there non-surgical treatment options?
• What will happen if I delay treatment?
• What type of surgery is planned?
• What are the expected benefits?
• What are the possible risks?
• How long might recovery take?

You do not need to remember everything discussed during the consultation. Consider writing down your questions beforehand and taking notes during the discussion.

Understanding the purpose of surgery can help you make an informed decision and prepare realistically for recovery.

2. Tell Your Doctor About Your Medical History

Your surgical team needs a complete picture of your health.

Tell your doctor if you have or have previously had:

• Diabetes
• High blood pressure
• Heart disease
• Asthma or other breathing problems
• Kidney or liver disease
• Previous complications with anaesthesia
• Bleeding or clotting problems
• Allergies
• Previous surgeries
• Any recent illness or infection

Also tell your healthcare team if you are pregnant or think you may be pregnant.

Do not assume that a condition is too minor to mention. Even seemingly unrelated health information can be relevant when planning anaesthesia or surgery.

3. Make a Complete List of Your Medicines

One of the most important parts of surgical preparation is providing your doctor with an accurate list of everything you take.

This includes:

• Prescription medicines
• Over-the-counter medicines
• Painkillers
• Vitamins
• Herbal products
• Dietary supplements
• Medicines taken occasionally

Some medicines may need to be continued, while others may need to be temporarily adjusted or stopped before surgery. This depends on the medicine, your health, and the type of procedure.

Never stop a prescribed medicine on your own. Follow the specific instructions provided by your surgeon or anaesthetist.

The NHS recommends that patients know and share information about all medicines, vitamins, and herbal supplements they take as part of preoperative preparation.

4. Complete the Recommended Preoperative Tests

Depending on your age, health, type of surgery, and anaesthesia, your doctor may recommend certain investigations before the operation.

These may include:

• Blood tests
• Urine tests
• ECG
• Chest imaging
• Ultrasound
• CT or MRI
• Other specialised tests

Not every patient requires every test.

The purpose is to give your healthcare team relevant information about your health and identify issues that may need attention before surgery. Preoperative tests are selected according to the operation and the type of anaesthetic being used.

If you already have recent medical reports, scans, prescriptions, or test results, ask whether you should bring them to your appointment.

5. Meet the Anaesthesia Team

Many patients are more worried about anaesthesia than the operation itself.

Before surgery, an anaesthetist may review your medical history, medicines, allergies, previous anaesthesia experiences, and other factors that could affect your care.

Depending on the procedure, you may receive:

• General anaesthesia
• Regional anaesthesia
• Local anaesthesia
• Sedation

The appropriate option depends on your surgery and individual health needs.

This is a good opportunity to ask questions such as:

• What type of anaesthesia will I receive?
• How will I be monitored?
• When can I eat and drink again?
• What should I expect immediately after anaesthesia?

Being open with the anaesthesia team is important. Mention any previous difficulty with anaesthesia, allergies, breathing problems, or other concerns.

6. Follow Fasting Instructions Carefully

Your doctor or hospital will tell you when you need to stop eating and drinking before surgery.

The instructions can vary depending on the procedure and type of anaesthesia, so do not assume that the same fasting rules apply to every surgery.

If you have been instructed to fast, follow the timing provided by your medical team exactly. This may include restrictions on food, drinks, chewing gum, sweets, or other items.

Fasting is important because having food or liquid in the stomach during anaesthesia can increase the risk of vomiting and aspiration.

If you have diabetes or take medicines that affect blood sugar, tell your surgical team in advance so they can provide appropriate instructions.

7. Take Care of Your General Health

If you have several days or weeks before planned surgery, use that time to take care of your general health as advised by your doctor.

Depending on your condition, this may include:

• Eating a balanced diet
• Staying physically active if medically appropriate
• Getting adequate sleep
• Maintaining good blood sugar control
• Taking prescribed medicines correctly
• Avoiding smoking
• Limiting alcohol as advised
• Managing existing medical conditions

Do not begin a new exercise programme, diet, supplement, or medication specifically for surgery without discussing it with your healthcare provider.

Your doctor may also advise you to stop smoking before surgery because smoking can affect healing and respiratory health.

8. Maintain Good Hygiene Before Surgery

Your hospital may provide specific instructions about bathing or showering before surgery.

You may also be asked to remove:

• Jewellery
• Body piercings
• Makeup
• Nail polish
• Contact lenses

These instructions can vary between hospitals and procedures.

For example, the NHS advises patients to remove body piercings, makeup, and nail polish before an operation and notes that some hospitals may ask patients to bathe or shower before surgery.

Follow the instructions given by your hospital rather than relying on general advice found online.

9. Plan for the Day of Surgery

A little practical planning can make the hospital visit less stressful.

Ask the hospital:

• What time should I arrive?
• Where should I report?
• How long might I stay?
• Should I bring previous medical reports?
• What documents are required?
• Can I bring a family member?
• What should I wear?
• What personal items should I bring?

If you are likely to receive general anaesthesia or sedation, arrange transportation and assistance according to your hospital's instructions.

If you are expected to stay overnight, pack only essential items and follow the hospital's guidance about personal belongings.

10. Arrange Help at Home

Recovery does not end when you leave the operating room.

Depending on your procedure, you may temporarily need help with:

• Preparing meals
• Household tasks
• Shopping
• Travelling to follow-up appointments
• Looking after children
• Moving around the house

If your doctor expects you to have restricted activity after surgery, make arrangements before the procedure rather than waiting until you return home.

Planning ahead can allow you to concentrate on recovery instead of worrying about everyday responsibilities.

11. Understand Your Expected Recovery

Ask your surgeon what recovery may look like before the operation.

Important questions include:

• How long will I stay in the hospital?
• When can I walk?
• When can I return to work?
• When can I drive?
• When can I exercise?
• Will I need physiotherapy?
• When will my stitches or dressing be checked?
• What symptoms should make me contact the hospital?

Recovery varies considerably between procedures and patients. Someone undergoing a minor procedure may return to normal activities quickly, while major surgery may require several weeks or longer.

Your surgeon's instructions should take priority over general information.

12. Ask About Pain Management

Pain after surgery is common, but it can usually be managed using an appropriate treatment plan.

Ask your healthcare team:

• What type of pain should I expect?
• Which medicines will I receive?
• How often should I take them?
• Are there side effects I should watch for?
• When should I contact the hospital if pain becomes worse?

Good pain management can make it easier for patients to rest, move safely, and follow their recovery plan.

Do not increase or decrease pain medicines without medical advice.

13. Know the Warning Signs After Surgery

Before leaving the hospital, make sure you know which symptoms require medical attention.

Depending on the type of operation, warning signs may include:

• Difficulty breathing
• Severe or worsening pain
• Heavy bleeding
• High or persistent fever
• Increasing redness or swelling around the wound
• Pus or unusual discharge
• Persistent vomiting
• Confusion or unusual drowsiness
• Sudden weakness or other concerning symptoms

The exact warning signs depend on the operation.

Ask your surgical team for clear instructions about what is normal during recovery and what requires urgent medical evaluation.

14. Understand the Surgical Safety Process

Patients sometimes feel anxious when they see healthcare professionals repeatedly asking the same questions before surgery. These checks are an important part of patient safety.

The WHO Surgical Safety Checklist includes confirmation of the patient's identity, procedure, surgical site, allergies, anaesthesia-related concerns, equipment, and other safety considerations. It also includes a final check before the patient leaves the operating room.

These structured checks are designed to encourage communication among surgeons, anaesthesia professionals, and nursing staff and help ensure important safety steps are not missed.
