Preoperative fitness screening

Overview

Preoperative fitness screening is a check-up done before surgery to see how well your body can handle the stress of an operation. It helps your healthcare team plan the safest care for you, including any extra support you may need to reduce risks.

Yes, this type of screening is standard for many surgeries, especially for older adults or people with long-term health conditions. It helps make surgery safer.

Anyone who is scheduled for a major operation may have preoperative fitness screening. It is especially important for people with heart or lung conditions, diabetes, or a history of smoking.

Symptoms

Common symptoms

• Shortness of breath with mild activity

Symptoms in children

• Tiring easily during play or exercise

Symptoms in older adults

• Feeling weak or unsteady on your feet

Causes

Main causes

• Preoperative fitness screening is not a disease – it is a check. The findings can be affected by your current fitness level, any medical conditions, and your age.

Risk factors

• Being overweight or obese
• A history of heart disease, stroke, or lung problems
• Smoking or heavy alcohol use
• Not being physically active
• Diabetes or high blood pressure

When to see a doctor

See a doctor urgently if:

• If you have chest pain, shortness of breath, or fainting – call emergency services right away.

Book a routine appointment if:

• As soon as you know you need surgery, ask your doctor if a fitness screening is recommended for you.

Diagnosis

Preoperative fitness screening is not a diagnosis – it is an assessment to estimate your risk. Your healthcare team will review your medical history, do a physical exam, and may perform simple tests.

Tests that may be done

• A walking test (often the six-minute walk test) to measure your endurance
• An electrocardiogram (ECG) to check your heart’s rhythm
• Blood tests to check your general health
• Lung function tests (spirometry) if you have breathing problems

What to expect at your appointment

You will meet with a doctor or nurse who will ask about your health, medicines, and lifestyle. They may ask you to walk for a short time or do other simple exercises. The whole visit usually takes 30 to 60 minutes.

Treatment

The results of the screening help your team decide if you need any extra care before surgery. This can include advice on exercise, nutrition, or medicines to improve your fitness. In some cases, they may advise postponing the operation until you are healthier.

Self-care at home

• Start a gentle exercise program, like walking, as your doctor advises
• Eat a balanced diet with plenty of fruits and vegetables
• If you smoke, try to stop – your healthcare team can help
• Get good sleep and manage stress

Medical treatments

Your doctor may prescribe medicines to control conditions like high blood pressure or diabetes before surgery. No specific drug names are provided. In some cases, you may need to see a specialist for a more detailed heart or lung evaluation. The goal is to lower your risk so the operation is as safe as possible.

When is surgery considered?

If the screening shows you are at high risk, your surgical team may choose a less invasive operation, or they may recommend delaying surgery until your fitness improves. In some urgent cases, the surgery goes ahead with extra monitoring and support.

Living with this condition

After a preoperative screening, you will work with your healthcare team to follow any recommended changes. This may mean adding short walks to your day or taking new medicines. The goal is to be as healthy as possible before your operation.

Lifestyle tips

• Aim for 30 minutes of moderate activity most days, like brisk walking
• Eat a heart-healthy diet low in salt and added sugars
• Stay hydrated and limit alcohol
• Get enough rest and try relaxation techniques

Diet and exercise

A balanced diet with lean protein, whole grains, fruits, and vegetables can help improve your strength and healing. Regular physical activity, even light walking, can boost your stamina and reduce surgery risks.

Mental health and emotional wellbeing

Worry about surgery and screening results is normal. It can help to talk about your feelings with your healthcare team, family, or a counsellor. Many hospitals offer support before surgery to help you feel prepared and calm.

Prevention

Preoperative fitness screening is not something you prevent – it is a tool to catch problems early. But you can improve your fitness before surgery by staying active, eating well, and managing any long‑term health conditions.

Vaccines

Not directly related, but keeping up with recommended vaccines (like flu and pneumonia) can help reduce complications from surgery.

Screening programmes

Preoperative fitness screening itself is a screening test. If you are having surgery, ask your surgeon or anaesthetist if you need one.

Complications

If left untreated

• Higher risk of complications during surgery, such as heart attack or stroke
• Slower recovery after the operation
• Longer hospital stay

Long-term outlook

For most people, preoperative fitness screening leads to a safer operation and better recovery. Even if you are found to be less fit, many people improve their health with simple steps, making surgery much lower risk. Your healthcare team will work with you to find the best path forward.
