The Nutrition Risk Screening 2002 (NRS-2002) and Malnutrition Universal Screening Tool (MUST) are validated tools that include BMI assessment, recent weight loss, and disease severity to evaluate nutritional risk, as suggested by the European Society for Clinical Nutrition and Metabolism 1, 2
The Nutritional Risk Index (NRI) incorporates serum albumin level and weight loss ratio to assess nutritional status, according to the American Society for Parenteral and Enteral Nutrition 2

A thorough history focusing on dietary intake patterns, recent changes, and gastrointestinal symptoms is essential for evaluating significant weight loss in a postpartum patient, as recommended by the American Gastroenterological Association 3, 1
Medication review to identify medications that may affect weight is crucial, as suggested by the American College of Gastroenterology 4
Physical examination should include vital signs, examination for signs of malnutrition, and assessment for underlying systemic disease, according to the Society of Critical Care Medicine 3, 6

Nutritional supplementation with appropriate caloric intake (500-1000 kcal/day above baseline requirements) is recommended for patients with significant malnutrition, as suggested by the American Society for Parenteral and Enteral Nutrition 3, 1
Protein supplementation to prevent further muscle loss is essential, according to the American College of Gastroenterology 4
Referral to a registered dietitian for comprehensive nutritional assessment and planning is recommended, as suggested by the Academy of Nutrition and Dietetics 2

Frequent follow-up visits to monitor weight trajectory are essential, as recommended by the American Gastroenterological Association 3
Regular reassessment of nutritional status using the same screening tools is crucial, according to the American Society for Parenteral and Enteral Nutrition 1
Adjusting the nutritional plan based on response to interventions is necessary, as suggested by the American College of Gastroenterology 4

Weight loss exceeding 5% of body weight in 1 month requires urgent evaluation, as recommended by the American Society for Parenteral and Enteral Nutrition 1
Presence of fever, night sweats, or other constitutional symptoms necessitates urgent evaluation, according to the American Gastroenterological Association 3
