Preparing Your Body for Surgery

Unscripted's Guide to Optimizing Healing, Reducing Complications, and Building Resilience

Healing begins long before the first incision.

Why Preparation Matters

Surgery is a controlled trauma. While surgeons repair tissue, your body is responsible for:

·      Managing inflammation

·      Producing collagen and new tissue

·      Preventing infection

·      Regulating blood sugar

·      Clearing anesthesia

·      Producing energy

·      Repairing nerves

·      Preventing excessive scar tissue

·      Returning the nervous system to a healing state

The weeks leading up to surgery represent an opportunity to improve your body’s resilience. Research consistently shows that better nutritional status, metabolic health, sleep quality, stress regulation, and physical conditioning lead to better surgical outcomes.

Think of surgery as running a marathon. You wouldn’t wait to prepare until the night before, right?

Part 1: Biological Preparation

1. Lower Chronic Inflammation

A certain amount of inflammation is essential after surgery, but excessive baseline inflammation can delay healing and increase complications.

Focus on:

·      Colorful vegetables (7–10 servings daily)

·      Omega-3-rich fish (salmon, sardines)

·      Extra virgin olive oil

·      Berries

·      Herbs and spices (turmeric, ginger, rosemary)

·      Green tea

·      Adequate hydration

Reduce or eliminate:

·      Alcohol

·      Ultra-processed foods

·      Refined sugars

·      Industrial seed oils

·      Excess fried foods

2. Build Protein Reserves

Healing dramatically increases your protein needs.

Protein supports:

·      Immune function

·      Collagen production

·      Muscle preservation

·      Wound healing

·      Recovery from anesthesia

Aim for:

1.2–1.6 g protein/kg body weight/day

Examples:

·      Eggs

·      Fish

·      Grass-fed beef

·      Chicken

·      Greek yogurt

·      Cottage cheese

·      Collagen peptides (in addition to—not instead of—complete protein)

3. Optimize Blood Sugar

Even mild elevations in blood glucose impair:

·      White blood cell function

·      Wound healing

·      Collagen formation

·      Infection resistance

Helpful habits:

·      Prioritize protein first at meals

·      Walk 10–15 minutes after eating

·      Limit added sugars

·      Eat fiber with every meal

·      Maintain regular meal timing

4. Correct Nutrient Deficiencies

Healing depends on adequate nutrient stores.

Important nutrients include:

·      Vitamin D

·      Vitamin C

·      Zinc

·      Magnesium

·      Vitamin A

·      Iron (when deficient)

·      Selenium

·      Copper

·      B vitamins

Whenever possible, assess deficiencies before supplementing aggressively.

5. Support Mitochondria

Surgery places enormous demands on cellular energy production. Your cells need energy to repair and rebuild healthy tissue.

Support mitochondrial health through:

·      Regular movement

·      Morning sunlight

·      Adequate sleep

·      Protein intake

·      Colorful plant foods

·      CoQ10 (when appropriate)

·      Magnesium

·      Omega-3 fats

6. Support Natural Detoxification

The liver metabolizes anesthetic medications and many pharmaceuticals.

Rather than “doing a detox,” focus on supporting the body’s normal detoxification systems.

Support includes:

·      Hydration (cellular hydration, not just drinking more plain water)

·      Daily bowel movements

·      Cruciferous vegetables

·      Garlic

·      Onions

·      Adequate protein

·      Fiber

·      Regular movement

Functional medicine emphasizes supporting Phase 2 detoxification and elimination before increasing Phase 1 detoxification, because this makes sure metabolites are effectively cleared and can acutally be gone from the body.

During this time, avoid aggressive detox programs, prolonged fasting, or restrictive cleanses. That will do more harm that good in the weeks leading up to a surgery.

7. Minimize Environmental Toxin Exposure

Your detoxification systems will already be busy processing anesthesia and medications.

Reduce unnecessary exposures by:

·      Drinking filtered water

·      Avoiding cigarette smoke

·      Choosing fragrance-free personal care products

·      Avoiding pesticides when possible

·      Limiting plastics with hot food

·      Using glass or stainless steel food containers

Supporting natural detoxification starts with reducing incoming exposures before increasing detoxification efforts.

8. Build Muscle Before Surgery

Muscle is one of the strongest predictors of surgical recovery.

Continue strength training (as tolerated) until instructed otherwise.

Benefits include:

·      Faster mobility

·      Better insulin sensitivity

·      Better immune function

·      Reduced muscle loss after surgery

Even 2–4 weeks of strength training can improve resilience.

9. Optimize Sleep

Healing hormones are produced primarily during sleep.

Aim for:

·      7.5–9 hours nightly

·      CONSISTENT BEDTIME (this is a biggie; pick a bedtime and stick to it +/- 30 minutes, 6 days out of the week)

·      Morning sunlight

·      Dark, cool room

·      No alcohol before bed

·      Limit screens one hour before sleep

Poor sleep increases:

·      Cortisol

·      Pain sensitivity

·      Blood sugar

·      Infection risk

10. Improve Cardiovascular Fitness

Walking, cycling, swimming, or zone 2 exercise improves:

·      Oxygen delivery

·      Circulation

·      Mitochondrial function

·      Recovery capacity

Even 20–30 minutes most days can improve surgical outcomes.

Part 2: Preparing the Nervous System

Your nervous system largely determines whether your body prioritizes protection (i.e. survival mode) or healing.

You've probably heard this before, but the autonomic nervous system has two primary modes:

Sympathetic (“Fight, Flight, or Freeze”)

·      Elevated cortisol

·      Increased heart rate

·      Reduced digestion

·      Heightened pain perception

·      Slower tissue repair

Parasympathetic (“Rest, Digest, or Heal”)

·      Improved circulation

·      Better digestion

·      Lower inflammation

·      Enhanced immune function

·      Improved wound healing

The goal is not to eliminate stress, a certain amount is good for us. It's to increase your ability to return to a regulated state.

1. Practice Physiological Regulation Daily

Spend 10–20 minutes each day on one or more of the following:

·      Slow diaphragmatic breathing

·      Box breathing (4-4-4-4)

·      Extended exhale breathing

·      Yoga Nidra

·      Meditation

·      Prayer

·      Mindfulness

Consistency matters more than duration.

2. Use Breath Before Surgery

When anxiety increases:

Inhale through your nose for 4 seconds.

Exhale slowly for 6–8 seconds.

Repeat for 5 minutes.

Longer exhalations stimulate the vagus nerve and help shift the body toward parasympathetic activity.

3. Reduce Threat Signals

The brain interprets uncertainty as danger.

Prepare by:

·      Asking questions beforehand

·      Knowing your recovery plan

·      Visiting the hospital if possible

·      Packing early

·      Creating a recovery space at home

Reducing uncertainty often reduces nervous system activation.

4. Visualize Healing

Elite athletes and surgical psychology research both support guided visualization. The results are pretty amazing, don't count this one out.

Spend 5–10 minutes imagining:

·      Entering surgery calmly

·      Your surgical team working skillfully

·      Your tissues healing

·      Walking comfortably

·      Returning to activities you enjoy

Visualization can reduce anxiety and improve confidence.

5. Strengthen Your Social Support

Humans regulate through connection.

Before surgery:

·      Arrange help

·      Accept assistance

·      Communicate your needs

·      Stay connected with supportive people

Isolation increases stress physiology.

6. Limit Information Overload

Reading worst-case stories online activates the brain’s threat system.

Choose trusted medical sources and avoid doom-scrolling in the days leading up to surgery.

7. Practice Gratitude

Daily gratitude shifts attention away from fear and toward safety.

Write down:

·      Three things going well

·      Three people you appreciate

·      One thing your body continues to do well

8. Reframe Surgery

Instead of:

“My body is broken.”

Consider:

“My body is about to receive help.”

Instead of:

“I’m scared.”

Try:

“My nervous system is trying to protect me.”

Small changes in internal dialogue can reduce physiological stress responses.

The Week Before Surgery

Focus on:

·      Protein with every meal

·      Hydration

·      Walking daily

·      Gentle strength training (if appropriate)

·      Consistent sleep

·      Avoid alcohol

·      Follow medication instructions from your surgeon

·      Prepare your recovery space

·      Continue breathing and mindfulness practices

Avoid experimenting with new supplements or restrictive diets.

The Day Before Surgery

·      Eat nourishing meals if permitted

·      Follow all fasting instructions exactly

·      Stay hydrated until instructed otherwise

·      Pack comfortable clothing

·      Practice relaxation exercises

·      Go to bed early

·      Avoid excessive screen time

The Morning of Surgery

·      Follow fasting instructions precisely.

·      Take only medications approved by your surgical team.

·      Practice slow breathing while traveling to the hospital.

·      Focus on one thought:

“My body knows how to heal. My medical team knows how to help. Together, we’re supporting my recovery.”

Key Takeaways

The body heals best when it feels safe, well nourished, and well supported.

Intentionally preparing for surgery is about creating the best possible environment for healing. By optimizing nutrition, movement, sleep, metabolic health, and nervous system regulation before surgery, you can improve your resilience, support recovery, and help your body respond more effectively to the stress of the procedure.
