Preparing your body before an operation can speed recovery and improve outcomes. What prehabilitation is and how to do it safely.
When facing a planned operation, most people focus entirely on the surgery and the recovery afterwards. There is a valuable, often overlooked window before it: the weeks of preparation. Prehabilitation, or prehab, means getting your body as fit and strong as possible before surgery, and growing evidence shows it can lead to fewer complications and a faster, smoother recovery. Going into an operation stronger is one of the best things you can do to come out of it well.
Why preparing before surgery helps
Surgery is a major physical stress, and recovery draws heavily on your strength, fitness and reserves. Think of it like a challenge you can train for. The fitter and stronger you are going in, the better your body copes with the stress of the operation and the demands of recovery, when you may be less active and lose strength quickly. Research increasingly links better pre-surgery fitness, strength and nutrition to fewer complications, shorter hospital stays and quicker recovery for many procedures. Prehab is the natural bookend to the rehabilitation that follows, which we cover in returning to exercise after surgery.
What prehab involves
The specifics depend on your operation and health, and should be guided by your surgical team, but prehab commonly includes:
- Strength training, to build the muscle reserve that recovery draws on and counter the strength you may lose afterwards, from strength training for longevity.
- Aerobic exercise, such as walking, to improve the fitness that helps you cope with the operation.
- Breathing exercises, often recommended before chest or abdominal surgery to support the lungs.
- Good nutrition, with enough protein to support healing and maintain muscle.
- Stopping smoking and limiting alcohol, which improve healing and reduce complications.
Even a few weeks of preparation can be worthwhile, and longer is often better where time allows.
Make the most of the window
If you have a planned operation scheduled, the time before it is an opportunity, not just a wait. Used well, it leaves you stronger and fitter, so you recover faster and return to your life sooner. This is especially valuable for older adults and anyone facing major surgery, where the difference in recovery can be significant. It also gives you a sense of doing something active and positive in a situation that can otherwise feel passive and anxious.
Coordinate with your medical team
This is the essential point. Prehab must be tailored to your specific operation, health and any restrictions, so it should be planned with your surgeon, doctor, or a physiotherapist who can liaise with them. This is general fitness education, not medical advice, and some conditions or planned procedures require particular precautions. Get clearance and guidance before starting, and let your medical team lead.
