Nutrition, hydration, growth, and deficiency monitoring

Growth charts and food logs can help a clinician see patterns, but a single weight, percentile, food count, or home calculation cannot establish adequate nutrition or diagnose ARFID.[1][2]

What to bring to care

• accepted foods and drinks, and important changes over time
• hydration concerns, urination changes, fatigue, dizziness, or fainting
• constipation, pain, nausea, vomiting, chewing, or swallowing symptoms
• growth records or measurements taken by clinicians
• school and social impact
• medication, sleep, and appetite timing
• the child’s own perspective

What you can try now

Keep established safe foods and usual fluids available according to the child’s existing care plan. Use the observation log to record patterns, not to create calorie targets. Do not start supplements, tube-feed changes, restrictive diets, food elimination, or forced intake without individualized guidance.

CDC and WHO growth resources are reference tools for clinicians and families; interpretation depends on age, development, health history, and the pattern over time.[1][2] Reviews of pediatric ARFID nutrition also emphasize individualized, multidisciplinary assessment and limited evidence for universal dietary plans.[3]

Who can help and what to ask

Start with the pediatrician or primary care clinician. Ask whether a pediatric dietitian, feeding/swallowing SLP, gastroenterologist, mental-health clinician, or specialized program is appropriate. Ask who owns monitoring for hydration, growth, nutrition, medication effects, and feeding progress.

Seek prompt care for

Dehydration, fainting, marked weakness or drowsiness, rapid weight change, inability to keep fluids down, dependence on supplements or tube feeding, or rapidly worsening intake. Use red flags and urgent help.
