Pre-Surgery Nutrition: How to Prepare Your Body

Written by Prime Surgical Suites | April 16, 2025

Getting ready for surgery involves more than just paperwork and pre-op checklists—what you eat in the days and weeks before your procedure can have a direct impact on how quickly and comfortably you recover.

Good nutrition plays a key role in strengthening your immune system, reducing inflammation, and speeding up healing after surgery. If you’re scheduled for a procedure at Prime Surgical Suites in Granite Falls, NC, knowing how to fuel your body before surgery can set you up for a better outcome from day one.

Here’s how to prep your plate and prioritize your health before surgery.

Why Nutrition Matters Before Surgery

Boosts Your Immune System

A diet rich in vitamins, minerals, and antioxidants supports immune function, reducing your risk of infection during and after surgery. Nutrients like vitamin C, zinc, and probiotics help your body fight off bacteria and promote tissue healing. According to the Cleveland Clinic, these nutrients are especially critical in the weeks before surgery.

Reduces Inflammation and Supports Healing

Inflammation can slow healing and cause additional pain. Anti-inflammatory foods—like those containing omega-3 fatty acids—help your body manage post-surgery swelling more effectively.

Maintains Muscle Strength

Adequate protein intake before surgery helps prevent muscle breakdown, especially if you’re expected to have limited mobility during recovery. Maintaining strength aids in balance, mobility, and wound healing.

Stabilizes Blood Sugar and Energy Levels

Balanced blood sugar reduces stress on the body, improves response to anesthesia, and supports a faster recovery. Eating complex carbohydrates (like oats, brown rice, and vegetables) provides steady energy without blood sugar spikes.

What to Eat in the Weeks Leading Up to Surgery

Protein-Packed Foods for Tissue Repair

    • Protein supports tissue regeneration, muscle repair, and immune function.
    • Best sources: Chicken, turkey, fish, eggs, tofu, Greek yogurt, legumes, and lean beef.

Vitamin-Rich Fruits and Vegetables

    • Vitamins A and C support immunity and collagen production, which aids in healing.
    • Best sources: Leafy greens, berries, citrus fruits, carrots, bell peppers, and sweet potatoes.

Healthy Fats for Inflammation Control

    • Unsaturated fats help regulate inflammation and assist with cell regeneration.
    • Best sources: Avocados, olive oil, salmon, chia seeds, and almonds.

Whole Grains for Sustained Energy

  • Fiber-rich carbohydrates promote digestive health and blood sugar stability.
  • Best sources: Brown rice, quinoa, whole wheat bread, oats, and lentils.

Hydration is Essential

    • Proper hydration supports circulation, helps flush out toxins, and preps your body for anesthesia.
    • Best sources: Water, herbal teas, and low-sugar electrolyte drinks like coconut water. 
    • The National Institutes of Health emphasizes hydration as a key component of pre-op preparation.

Foods and Drinks to Avoid Before Surgery

Processed and Sugary Foods


      • These can trigger inflammation and impair immune function.
      • Avoid: Soda, packaged snacks, candy, pastries, and fried fast food.

Caffeine and Alcohol


      •  Both contribute to dehydration and may interfere with anesthesia.
      • Avoid: Coffee, energy drinks, beer, wine, and liquor in the days before surgery.

High-Sodium Foods


      • Salt causes fluid retention and may increase swelling.
      • Avoid: Canned soups, cured meats, salty snacks, and frozen meals.

Fatty and Greasy Foods


      • Heavy meals are harder to digest and can increase nausea risk post-surgery.
      • Avoid: Fried foods, heavy cream sauces, and fast food burgers.

Natural Blood Thinners (Supplements & Foods)


    • Certain ingredients can increase bleeding risk.
    • Avoid: Fish oil, garlic, ginseng, vitamin E supplements, and over-the-counter aspirin—always consult your doctor. 
    • The Mayo Clinic recommends reviewing all supplements at least two weeks before surgery.

The Final 24 Hours: 4 Steps for Preparing for Surgery

Follow Fasting Instructions Carefully

Most procedures require no food or drink for 8+ hours beforehand. Some allow clear fluids—always confirm with your surgical team.

Hydrate Before Your Cut-Off Time

Drink plenty of water in the hours leading up to your fasting window to prevent dehydration and reduce nausea post-op.

Choose Light, Balanced Meals the Day Before


Eat something like grilled chicken, steamed vegetables, and whole grains for your last meal. Avoid anything greasy, heavy, or spicy.

Get a Full Night of Sleep

Your body heals best when well-rested. Aim for 7–9 hours of quality sleep before your procedure.
