Preparing Your Body for Surgery: Peri-Operative Nutrition with Dr. Brian Waterman
Preparing for surgery involves more than setting a date and arranging a ride home. What you eat—and drink—before and after your procedure plays a critical role in how well your body heals, how quickly you regain strength, and how smoothly your recovery progresses.
Dr. Brian Waterman and his team emphasize a comprehensive, evidence-based approach to surgical care that places the patient at the center of the process. In collaboration with anesthesiology, physical therapy, and nutrition specialists, this approach aligns with modern Enhanced Recovery After Surgery (ERAS) principles—designed to support your body before surgery, protect it during the procedure, and promote efficient recovery afterward.
One of the most powerful (and overlooked) tools you have in this process is nutrition.
Why Nutrition Matters Around the Time of Surgery
Surgery places a temporary stress on the body. Your physiologic response to that stress—including inflammation, hormonal changes, and metabolic demand—directly influences pain control, wound healing, infection risk, and overall recovery time.
- Optimizing nutrition before and after surgery helps to:
- Preserve muscle mass and strength
- Support immune function and wound healing
- Improve energy levels and blood sugar regulation
- Reduce complications and prolonged recovery
In short, fueling your body well allows it to do what it does best: heal.
The Foundations of a Recovery-Focused Diet
While individual needs vary, most patients benefit from focusing on three core elements:
1. Adequate Protein Intake
Protein is essential for tissue repair and maintaining muscle during periods of limited activity. Aim to distribute protein throughout the day rather than saving it for one meal.
A strong start to the day matters. A protein-rich breakfast—often targeting 30–45 grams of protein—can help stabilize energy levels and support recovery processes early on.
2. Hydration and Electrolytes
Fluids support circulation, nutrient delivery, and normal cellular function. Staying well hydrated before and after surgery helps prevent fatigue, dizziness, and delayed healing.
3. Micronutrients from Whole Foods
Vegetables and fruits—especially deeply colored options like berries—provide antioxidants and vitamins that support immune function and reduce oxidative stress.
Foods and Beverages to Limit Around Surgery
The peri-operative period is not the time for dietary extremes, but certain foods can interfere with optimal healing and should be minimized when possible.
Refined and Excess Grains
While whole grains are often part of a healthy diet, some patients experience increased inflammation or blood sugar fluctuations when intake is high—particularly those with insulin resistance, diabetes, or excess abdominal weight. Prioritize protein, vegetables, and fruits first. If grains are included, keep portions modest.
Sugary Drinks and Juices
Sugar-sweetened beverages can cause rapid spikes in blood glucose, which may impair wound healing and increase stress on the body. Water, electrolyte solutions without added sugar, and unsweetened beverages are better choices.
Conventional Meal Replacement Shakes
Many commercially available shakes contain high sugar content and artificial sweeteners. These products may undermine metabolic control during recovery. If using a protein supplement, choose one that:
- Contains at least 25 grams of protein
- Has minimal carbohydrates (ideally under 5 grams)
- Avoids artificial sweeteners such as sucralose
Examples that meet these criteria include Isopure, Naked Whey, Vega Sport, and OWYN.
Alcohol
Alcohol increases inflammation, disrupts sleep, and places additional strain on the liver and immune system. Avoid alcohol during the peri-operative period to support optimal healing.
Highly Processed Foods
Processed foods often contain refined sugars, unhealthy fats, and additives that can increase inflammation and delay recovery. Whole, minimally processed foods are preferred whenever possible.
Reducing Stress to Improve Healing
Psychological stress affects physical recovery. Elevated stress hormones such as cortisol can interfere with blood sugar regulation and immune function. Education, preparation, and clear expectations—combined with supportive nutrition—help reduce this stress response and improve surgical outcomes.
Dr. Waterman’s team prioritizes patient education so you know what to expect before, during, and after surgery, allowing you to approach the process with confidence.
Take an Active Role in Your Recovery
Recovery doesn’t start after surgery—it starts now. Thoughtful nutrition is one of the most effective ways you can participate in your own healing process.
Dr. Brian Waterman and his team are committed to providing comprehensive, patient-centered care and resources to help you prepare for surgery and recover successfully. Additional educational materials and guidance are available to support you every step of the way.
