How This Protocol Works
Simple Explanation
Malnutrition occurs when the body doesn't get enough nutrients to function properly. It can result from inadequate intake (undernutrition), poor absorption, increased needs, or combinations thereof. It's a serious medical condition requiring careful management.
TYPES OF MALNUTRITION:
CAUSES:
WARNING - REFEEDING SYNDROME:
Restarting nutrition too quickly after starvation can cause dangerous electrolyte shifts (low phosphate, potassium, magnesium). This can be life-threatening. Medical supervision is essential.
TREATMENT PRINCIPLES:
* Oral nutritional supplements provide concentrated nutrition.
* Protein is essential for recovery - higher needs than normal.
* Micronutrients (vitamins/minerals) must be repleted.
* Thiamine is CRITICAL before refeeding to prevent complications.
Expected timeline: Nutritional recovery takes weeks to months depending on severity. Weight gain of 0.5-1 kg/week is typical target.
Clinical Perspective
Malnutrition: Nutritional deficiency state from inadequate intake, absorption, or increased requirements. Screening tools: MUST, NRS-2002, MNA. Diagnosis: low BMI, unintentional weight loss (>5% in 3 months or >10% in 6 months), low muscle mass. Causes: disease-related (cancer, COPD, CHF, CKD, cirrhosis, malabsorption), social/psychological (poverty, depression, dementia, eating disorders), oral/swallowing issues, medications.
CRITICAL: REFEEDING SYNDROME IS LIFE-THREATENING. High risk: BMI <16, weight loss >15% in 3-6 months, little/no intake >10 days, low K/PO4/Mg before feeding. Management: thiamine 200-300mg before feeding; start calories low (10-20 kcal/kg/day); increase slowly; monitor electrolytes daily; replace PO4, K, Mg aggressively. Treat underlying cause. Dietitian essential. Enteral > parenteral when GI functional.
* Oral Nutritional Supplements (A-grade): Calorie/protein dense. Cochrane: (PMID: 28332116). 250-500 kcal 1-3x daily.
* Protein (A-grade): Tissue repair. Guidelines: (PMID: 28332116). 1.2-1.5g/kg/day minimum.
* Multivitamin/Mineral (A-grade): Micronutrient repletion. Review: (PMID: 28332116). High-potency daily.
* Vitamin D (A-grade): Commonly deficient. Systematic review: (PMID: 28750270). 2000-4000 IU daily.
* Zinc (A-grade): Immune/wound healing. Meta-analysis: (PMID: 26845419). 15-30mg daily.
* Iron (A-grade): Anemia. Cochrane: (PMID: 28252380). Based on deficiency.
* B12/Folate (A-grade): Blood cells. Review: (PMID: 27450775). B12 1000mcg, folate 400-800mcg daily.
* Omega-3 (B-grade): Anti-inflammatory. Systematic review: (PMID: 27840029). 2g EPA+DHA daily.
* Thiamine (A-grade): CRITICAL for refeeding. Review: (PMID: 25248250). 200-300mg before/during refeeding.
Assessment targets: Weight, BMI, albumin/prealbumin (acute phase reactant caveat), lymphocyte count, electrolytes, specific micronutrient levels, functional status, handgrip strength.
Protocol notes: Refeeding: start 10-20 kcal/kg/day in high-risk; advance by 5 kcal/kg/day; monitor PO4, K, Mg, Na, glucose daily initially. Protein: adequate protein essential; may need 1.5-2g/kg in catabolic states. Route: oral first; enteral tube feeding if unable to meet needs orally; parenteral if GI non-functional. Diabetes: adapt; lower carb, more protein/fat. Sarcopenia: focus on protein + resistance exercise. Disease-specific: cancer cachexia, COPD, CHF have specific considerations. Elderly: higher protein needs, texture modifications may be needed. Social: food insecurity, access, cooking ability, support. Behavioral: eating disorders require specialized care. Medications: appetite stimulants (megestrol, mirtazapine, dronabinol) may help some. Monitoring: weekly weights; adjust intake based on response.
