Zinc	Essential for tissue repair and wound closure.	Eat: Beef, pumpkin seeds, cashews, lentils

What to Eat After Pilonidal Surgery

1. Protein & Energy Needs

• Adults in wound healing stages often need 1.25–1.5 g of protein/kg/day, and sometimes up to 2.0 g/kg/day in cases of severe or complex wounds.
• Energy requirements range from 30–35 kcal/kg/day in malnourished or healing patients.

2. Key Micronutrients

• Vitamin C, A, the B vitamins, E, zinc, iron, and calcium all play distinct roles in reducing inflammation, supporting collagen synthesis, immune function, and tissue remodelling.
• Amino acids like arginine, leucine, and glutamine support collagen formation, immune response, and protein synthesis.

3. Supplements & Special Formulas

• Oral nutritional supplements (ONS) enriched with arginine, protein, and antioxidants can enhance healing in patients with inadequate dietary intake.
• Systematic reviews suggest vitamins A, B, C, D, E, zinc, magnesium, and copper can support healing in skin incisions, burns, and pressure ulcers—but high‑quality evidence is limited.

4. Hydration

• Drinking at least 30 mL of water per kg body weight per day, about 1.5 L for a 50 kg person, is vital to support cell function and overall healing.

Should I Take Vitamins or Supplements?

Foods That Can Slow Healing (Use in Moderation)

Too much sugar → Increases inflammation, may slow wound healing

Excess alcohol → Can dehydrate and impair tissue repair

Very low-calorie diets → Not enough fuel for healing

Tips for Eating When You’re Not Feeling Great

• Eat small meals or snacks more often
• Smoothies with fruit, yogurt, or protein powder can be easier than big meals
• Add peanut butter, avocado, or cheese to boost calories
• Ask someone to help you prep simple meals

When to Talk to Your Doctor or Dietitian

• Losing weight fast
• Not eating at all for more than 2 days
• You have a condition like diabetes that affects healing
• You’re thinking about supplements and want to be sure
