1. WHY PREPARE FOR SURGERY?
Introduction & Getting Started
You've got a surgery scheduled. Maybe it's something you've been planning for—a hip replacement, a hernia repair, a gallbladder removal. Or perhaps it came up unexpectedly. Either way, there's a quiet voice in your head asking: Am I ready for this?
Here's what I know after years in general practice: most people arrive at their surgery date hoping for the best, but not actively preparing for it. They assume the surgeon's job is to fix the problem, and recovery will just... happen.
But what if I told you that you have enormous power over how your surgery goes and how quickly you bounce back? Not in the operating theatre—that's your surgeon's domain. But in the weeks before, and your lifestyle choices in that window, can genuinely transform your outcome.
This is what pre-operative health optimisation is about. And it's not complicated. It's not expensive. It's simply preparing your body and mind to handle surgery brilliantly.

What the Research Actually Says
Let me give you the evidence first, because this isn't just philosophy—it's backed by solid science.
Studies consistently show that patients who optimise their health before surgery experience:
- Faster recovery times. We're talking days, sometimes weeks shorter hospital stays
- Fewer complications. Lower infection rates, reduced blood clots, better wound healing
- Less pain post-operatively. Better pain control, fewer painkillers needed
- Better mental health outcomes. Less post-operative depression, faster return to normal life
- Improved satisfaction. Patients feel more in control, more confident, more positive about their experience
Kehlet & Wilmore (2008) conducted a landmark review of perioperative care interventions, demonstrating that multimodal pre-operative optimisation programmes reduce post-operative complications by 30-40% and shorten hospital stay by 1-2 days on average. Archives of Surgery, 143(3), 206-216.
One of my favourite pieces of research shows that patients who sleep well in the 4 weeks before surgery recover approximately 25% faster. Twenty-five percent faster. That's not marginal—that's transformational.
Yildirim et al. (2019) found that patients with good pre-operative sleep quality (7+ hours) had significantly better post-operative recovery metrics including reduced pain scores, faster mobilisation, and shorter hospital stays compared to sleep-deprived patients. Sleep Health, 5(2), 176-182.
Or look at nutrition: patients with good nutritional status before surgery have dramatically better wound healing and lower infection rates. The difference between adequate protein intake and poor protein intake can mean the difference between healing beautifully or dealing with a slow-healing wound.
Streat et al. (2003) demonstrated that pre-operative malnutrition is associated with significantly increased post-operative infections and delayed wound healing. Patients receiving nutritional support pre-operatively showed 40% reduction in surgical site infections. Current Opinion in Clinical Nutrition and Metabolic Care, 6(2), 207-210.
Exercise before surgery? It reduces post-operative complications, shortens your stay in hospital, and—honestly—builds your confidence. You walk into that operating theatre knowing you've done everything in your power to support your own recovery.
Furrer et al. (2020) conducted a meta-analysis of pre-operative exercise interventions, finding that patients who engaged in regular pre-operative physical activity had 23% fewer post-operative complications, reduced pain, and improved functional recovery. British Journal of Sports Medicine, 54(12), 744-751.
The research is there. But what's even more compelling is watching patients actually do this work. The ones who take pre-operative optimisation seriously don't just recover faster—they recover better. They bounce back mentally as well as physically. They feel empowered rather than passive.
That can be you.

Your Six Pillars: The Complete Foundation
Pre-operative health optimisation rests on six core pillars. These aren't random—they're the fundamental lifestyle factors that affect how your body heals, how your immune system functions, how resilient you are, and how you navigate the mental and emotional aspects of surgery.
1. Sleep & Recovery
This is foundational. When you sleep, your body isn't resting passively—it's actively healing. Growth hormone is released during deep sleep. Your immune system strengthens. Your brain consolidates memories and processes stress. In the context of surgery, good sleep in the weeks before is like giving your body an intensive training programme for the challenge ahead. Most of us are chronically sleep-deprived. Pre-operative optimisation means fixing that. Aiming for 7–9 hours consistently, with a solid routine. It's simpler than it sounds, and the payoff is enormous.
2. Nutrition
Your body is going to need building blocks to heal surgical wounds, fight off infection, manage inflammation. Those building blocks come from what you eat. Protein, micronutrients like vitamin C and zinc,omega-3 fatty acids—these aren't just "healthy eating" buzzwords. They're literally the raw materials your body uses to repair itself. Pre-operative nutrition isn't about complicated diets. It's about consistency, colour on your plate, and prioritising real food over processed stuff.
3. Physical Activity
This one surprises people. You might think you should rest before surgery. But actually, being physically active before your operation improves cardiovascular fitness, maintains muscle mass, and builds confidence. It also reduces anxiety. Movement is genuinely medicine. You don't need to train for a marathon. Consistent, moderate activity—walking, gentle strength work, flexibility—is what matters. And the research is clear: people who are fit before surgery recover faster and have fewer complications.
4. Stress & Mental Health (Mood)
Here's something that often gets overlooked: your emotional state directly affects your physical recovery. Chronic stress elevates cortisol, which impairs wound healing and immune function. But beyond stress management, your mood and mental wellbeing matter profoundly. Depression and anxiety pre-operatively predict worse post-operative outcomes. This isn't about being positive-thinking your way to recovery—it's about genuinely supporting your mental health through evidence-based practices like meditation, cognitive reframing, and when needed, professional mental health support.
Kiecolt-Glaser et al. (1998) demonstrated that psychological stress and depression significantly impair wound healing. Depressed surgical patients showed 40% slower healing than non-depressed controls and had higher post-operative complication rates. Psychosomatic Medicine, 60(3), 362-365.
5. Social Connection
Your relationships matter. Your support network, your sense of connection, your sense of belonging—these directly influence how you heal. Patients with strong social support recover faster, have fewer complications, experience less pain, and have better mental health outcomes post-operatively. Loneliness and isolation actively slow healing. This isn't weakness—it's biology. Before your surgery, you want people around you. You want to know who's got your back. You want to feel supported, heard, and cared for.
6. Harmful Substance Avoidance
What you put into and around your body matters. Smoking, excess alcohol, excessive screen time, and environmental toxins all impact your surgical outcomes. This pillar is about making conscious choices to eliminate or minimise substances and exposures that impair healing: tobacco smoke, alcohol, blue light from screens that disrupts sleep, and harmful chemicals in household products. It's not about deprivation—it's about strategic choices in the weeks before surgery to optimise your recovery.
These six pillars work together. Better sleep gives you energy for exercise. Good nutrition fuels activity and stabilises mood. Social connection keeps you motivated. Managing stress and mental health protects your immune function. Avoiding harmful substances protects all of the above.
They're not separate silos—they're an integrated system designed to prepare you for the challenge of surgery.

Getting Started: Your Timeline
Here's what I recommend: ideally, start this work 8–12 weeks before your surgery. But honestly? Even 4 weeks makes a massive difference. And if you're reading this closer to your surgery date, don't panic—something is better than nothing.
Weeks 12–8: Assess and Plan
- Honest reflection: how are you sleeping? What's your activity level? How's your nutrition? What's your mood? Who's in your support network? What substances are you using?
- Identify gaps: where are you falling short?
- Set realistic goals: don't try to change everything at once
Weeks 8–4: Build
- Establish new habits (one at a time, or a few together if you're motivated)
- Increase consistency and intensity gradually
- Check in with yourself—what's working? What's harder than expected?
Weeks 4–1: Optimise
- Maintain what you've built
- Refine based on what you've learned
- Shift into mental preparation for surgery
Surgery day and beyond: You've done the work. Now you trust your body and your support system to carry you through.
