Nutrition Management in Patients with Colostomy

Introduction to Nutrition Management

• Oral nutrition intake should begin early after surgery, within a few hours, and be adjusted to individual bowel function, with a focus on high-fiber diet and adequate fluid intake in patients with impaired bowel motility and end colostomy, as recommended by the European Society for Clinical Nutrition and Metabolism 1
• Fluids and normal food can be taken immediately after surgery in most cases 1, 2
• Nutrition should be adapted to individual tolerance and type of surgery, with special caution required in older patients 1

Benefits of Early Nutrition

• Early nutrition promotes bowel motility, reduces the risk of postoperative ileus, and shortens hospital stay 3
• Regular monitoring of nutritional status before and after major surgery is necessary 1

Dehydration Prevention

• Dehydration should be avoided to minimize the risk of thromboembolism 4
• Patients should consume 2-2.5 liters of fluids per day, increasing during hot weather or exercise, with a focus on maintaining adequate hydration and electrolyte balance 5, 6, 7
• An oral rehydration solution should be used for high ileostomy output (>1 liter/day), consisting of:
• Patients should aim to maintain urinary sodium levels above 20 mmol/L to detect dehydration, and consider adding 0.5-1 teaspoon of extra salt daily to meals to supplement sodium, and increase potassium intake with foods like bananas, potatoes, spinach, fish, chicken, lean red meat, sweet potatoes, and avocados if serum levels are low 8, 7

Individualized Nutrition Plan

• Nutrition therapy should be initiated in cases of malnutrition or risk of malnutrition, as recommended by the European Society for Clinical Nutrition and Metabolism 1, 8
• Patients with blood cancers should consume 25-30 kcal/kg/day of energy needs, with a recommended protein intake of 1.0-1.5 g/kg/day to maintain muscle mass 5
• The macronutrient distribution should be 45-65% carbohydrates, 20-35% fat, and 15-20% protein, emphasizing complex carbohydrates, healthy fats, and moderate protein intake 9
• A plant-based diet high in vegetables, fruits, and whole grains should be continued, with a focus on whole grains as the foundation of carbohydrate intake 10, 9

Nutrition Therapy

• Patients should consume 5-9 servings of fruits and vegetables daily, emphasizing those rich in antioxidants, and choose low-fat protein sources like fish, lean poultry, eggs, low-fat dairy, nuts, seeds, and legumes 10, 9, 11
• Sources of omega-3 fatty acids like fish and walnuts should be prioritized, and saturated fats should be limited, with red and processed meats limited to 1-2 times/week maximum 9
• Refined grains, sugary foods, and alcohol should be limited 10, 9
• Vitamins and minerals should be provided in amounts approximately equal to the recommended daily allowance, with high-dose micronutrient supplementation avoided unless specific deficiencies are identified 5
• Daily multivitamin supplementation and monitoring of vitamin B12, iron, vitamin D, and calcium levels should be considered 5, 12, 7, 8

Parenteral Nutrition

• Parenteral nutrition should only be considered when the enteral route is not possible or contraindicated, as recommended by the European Society for Clinical Nutrition and Metabolism 8

Follow-up and Monitoring

• Regular nutritional screening and assessment should be conducted throughout the cancer journey, with a registered dietitian involved as part of the multidisciplinary care team 5, 11
• Patients with ileostomy should consume 60-80 g/day or 1.1-1.5 g/kg of ideal body weight of protein, prioritizing protein-rich foods, and follow a dietary progression from clear liquids to solid foods postoperatively, with regular evaluation of overall nutritional status, detection of recent weight loss, and monitoring of electrolyte levels 12, 13, 7
• Implement an educational program on fluid balance after discharge to reduce readmission rates for dehydration, and consider taking 1-2 tablets (2-4 mg) of loperamide 30 minutes before meals to reduce intestinal transit, and chew food well and be cautious with foods like fruit and vegetable skins, sweet corn, celery, and nuts (smooth nut butters are acceptable) 7
• The American College of Nutrition and the European Society for Clinical Nutrition and Metabolism recommend incorporating oral nutritional supplements (ONS) between meals to increase caloric and protein intake, with a focus on high-quality protein sources and calorie-dense foods, and suggest that intensive dietary counseling and oral supplements can prevent weight loss during radiotherapy and chemotherapy, with a strength of evidence rated as high 5, 14
• The Academy of Nutrition and Dietetics recommends avoiding restrictive diets that limit energy intake in patients at risk of malnutrition, and prolonged fasting during chemotherapy, as it can increase the risk of malnutrition, with a strength of evidence rated as high 10
