Weight Loss With Odynophagia and a Normal BMI
A 58-year-old woman is referred to an outpatient nutrition clinic after 3 months of progressive odynophagia and unintentional weight loss. Her weight has fallen from 78 kg to 71 kg; height 1.68 m; BMI 25.2 kg/m². She reports eating about half of her usual intake for the past 2 weeks because of pain on swallowing and early satiety. Mid-upper-arm circumference is 24 cm, handgrip strength 16 kg, and she has noticed loose-fitting rings and reduced ability to carry groceries. CRP is 28 mg/L, albumin 2.9 g/dL, and there is no peripheral edema. She lives alone, has no dysphagia workup yet, and takes omeprazole 20 mg daily. She has not been trying to lose weight. The referral asks whether she is malnourished and whether nutrition support should begin before the medical workup.
1. How would you classify her nutrition status using a validated approach, and which confounders must you account for when interpreting albumin and CRP?

I would screen first with MUST or NRS-2002, then diagnose with GLIM. On MUST she scores 1 for weight loss of 7 kg/78 kg = 9.0% in 3 months, giving medium risk; BMI contributes 0 because it is above 20. NRS-2002 would capture the reduced intake and weight loss as at least 2 points, also indicating risk. For GLIM, the phenotypic criterion is met by 9% weight loss in 3 months; reduced muscle mass is supported by MUAC 24 cm and handgrip 16 kg. The etiologic criterion is met by reduced intake plus inflammation (CRP 28 mg/L). This is moderate malnutrition with an inflammatory component, not simple starvation.
Albumin must not be used alone to diagnose malnutrition. It is a negative acute-phase reactant, so inflammation lowers it independently of intake; a value of 2.9 g/dL here reflects both inflammation and possible depletion and cannot distinguish them. CRP 28 mg/L confirms systemic inflammation and raises the possibility of cachexia if the odynophagia proves to be due to cancer or another chronic inflammatory disease. Cachexia requires ongoing muscle loss driven by inflammation, whereas this patient also has a clear mechanical intake problem. The normal BMI is misleading: functional decline, low grip strength, and a 9% loss are clinically important. The odynophagia is a red flag requiring prompt medical evaluation, not a reason to delay nutrition care.
2. What additional assessment data would you collect before finalizing the nutrition diagnosis and estimating requirements?

I would complete the nutrition-focused physical exam and gather data in four areas. First, intake and gastrointestinal history: a 24-hour recall and usual food pattern, texture tolerance, pain severity, early satiety, nausea, vomiting, bowel habits, and whether she has had any obstruction or bleeding. Second, functional and body-composition data: serial weight, MUAC, calf circumference, handgrip dynamometry, and if available bioelectrical impedance or CT muscle area; these help confirm loss of muscle rather than fat. Third, micronutrient and laboratory data guided by her presentation: complete blood count, ferritin, vitamin B12, folate, 25-hydroxyvitamin D, and electrolytes; albumin and CRP are already available but should be interpreted as inflammatory markers, not nutrition tests. Fourth, psychosocial and access issues: who shops and cooks, food insecurity, depression screening, dentition, and ability to obtain textured foods.
For requirements, I would estimate energy at 25-30 kcal/kg/day using current weight but recognize that current weight may overstate lean mass. Protein would be 1.0-1.5 g/kg/day depending on stress and renal function, with at least 1.0 g/kg/day initially. Before aggressive feeding I would check phosphate, potassium, and magnesium because she has had low intake and weight loss, although her BMI is not in the extreme range. I would also ask about alcohol use and previous dieting. The key judgment is to separate the mechanical swallowing problem from systemic inflammation and to avoid both undertreating her intake and overdiagnosing 'malnutrition' from albumin alone.
3. What immediate nutrition plan and monitoring would you recommend while the dysphagia workup is arranged?
Read the worked answer
My immediate plan would be food-first with texture modification and high-energy, high-protein oral nutrition supplements, while expediting the medical workup. I would recommend small, frequent meals and snacks every 2-3 hours, soft or pureed textures as tolerated, and 2 oral nutrition supplements per day providing about 300-400 kcal and 15-20 g protein each. I would address pain control before meals and review whether omeprazole is still needed, but I would not stop it abruptly. A speech-language pathology swallowing evaluation should be arranged urgently because odynophagia with weight loss requires exclusion of obstruction, malignancy, or severe esophagitis.
Monitoring would include daily or every-other-day weight during the initial period, a 3-day food and symptom diary, hydration status, and serum phosphate, potassium, and magnesium at baseline and after 48-72 hours of increased intake because she is at moderate refeeding risk. I would monitor intake to ensure she reaches at least 75% of estimated needs; if she cannot, temporary enteral nutrition could be considered, but only after the swallow evaluation and with caution. I would also set a follow-up visit within 1-2 weeks and coordinate with the primary team. The judgment call is not to wait for a diagnosis before treating inadequate intake, but also not to begin aggressive refeeding without electrolyte monitoring in a patient with low intake and weight loss.
