Peritoneal cancer surgery, including cytoreductive surgery (CRS) and HIPEC, requires careful nutritional planning to optimize healing, reduce complications, and support recovery. As one of Ahmedabad's leading GI oncosurgeons performing complex peritoneal cancer procedures, I've seen how proper nutrition significantly impacts patient outcomes and quality of life.

Understanding Peritoneal Cancer and Nutritional Challenges

Peritoneal cancer affects the thin membrane lining your abdominal cavity. Whether primary peritoneal cancer or metastatic disease from organs like ovary, colon, or appendix, this condition creates unique nutritional challenges:

Ascites (fluid accumulation) - Reduces appetite and protein levels
Bowel obstruction - Limits food intake and digestion
Malabsorption - Impairs nutrient absorption
Cancer cachexia - Causes muscle wasting and weight loss
Treatment side effects - Nausea, vomiting, taste changes from chemotherapy

Important: This guide provides general nutrition principles. Always follow your surgical team's specific dietary instructions, as individual needs vary based on surgery type, complications, and recovery progress.

Pre-Surgery Nutrition Preparation (2-4 Weeks Before)

Nutritional Optimization Goals

Preparing your body nutritionally before cytoreductive surgery and HIPEC improves surgical outcomes and accelerates recovery. Focus on:

Protein buildup - 1.2-1.5g per kg body weight daily
Immune system support - Adequate vitamins and minerals
Weight stabilization - Prevent further weight loss
Hydration optimization - Maintain fluid balance
