Pediatric Feeding Disorders: Recognition, Diagnosis, and Management

Etiology

Impairments across four functional domains—medical, nutritional, feeding skills, and psychosocial—provide a practical framework for identifying the underlying causes of PFDs and guiding comprehensive evaluation and management. Many conditions that lead to PFDs span multiple domains, highlighting the multifaceted nature of PFDs. Recognizing this complexity is critical for initiating appropriate referrals, coordinating interprofessional care, and implementing targeted interventions for each contributing factor.

Medical Factors

Medical contributors to PFDs often include congenital or acquired conditions that interfere with appetite regulation, swallowing, energy balance, or respiratory coordination during feeding. These conditions can involve multiple organ systems, as mentioned below.

• Gastrointestinal: Gastroesophageal reflux disease (GERD), delayed gastric emptying, eosinophilic esophagitis, duodenitis, celiac disease, and motility disorders such as aganglionosis (Hirschsprung disease) and congenital segmental intestinal dilatation.[2][3][4][5][6]

• Neurological: Cerebral palsy with associated choking and gagging during feeding, seizures, stroke, and neuromuscular disorders.[7][8]

• Cardiorespiratory: Congenital heart defects, bronchopulmonary dysplasia, cystic fibrosis, and other chronic lung diseases.

• Structural/anatomical: Cleft lip and palate, laryngomalacia, esophageal atresia, and choanal atresia.

• Genetic/syndromic: Down syndrome and other trisomies, Pierre Robin sequence, and CHARGE syndrome that involve facial dysmorphisms.

• Prematurity: Feeding tube dependence, ineffective sucking ability, and increased caloric requirements due to chronic illness.[9]

Nutritional Factors

Nutritional contributors to PFDs occur when a child's intake fails to meet their metabolic demands, resulting in nutrient deficiencies or impaired growth. These issues may result from:

• Food allergies or intolerances: These include cow's milk protein allergy, other food allergies, and lactose intolerance.

• Restricted diets: This occurs due to sensory or texture sensitivities, autism spectrum disorder, cultural dietary practices, and extreme food insecurity.

• Feeding regimens: This involves overly restrictive volumes or the use of inappropriate or diluted formulas.

• Malabsorption syndromes: These include celiac disease and cystic fibrosis.

Feeding Skill-Based Factors

These involve deficits in the motor skills necessary to safely and effectively consume age-appropriate foods and liquids. Such impairments include:

• Oral-motor dysfunction: Poor suck-swallow-breathe coordination and weak oral musculature that occurs with muscular dystrophies, myopathies, prematurity, congenital structural abnormalities such as cleft palate, cerebral palsy, and brain injuries. 

• Dysphagia: This results from neurological or anatomical abnormalities.

• Delayed development due to environmental influences: Limited exposure to varied textures, prolonged bottle use, and delayed introduction of solid foods.

• Structural/anatomical: Micrognathia, high-arched palate, or other structural abnormalities that impair the ability to hold utensils effectively, food placement, or swallowing.

• Transition difficulties: Refusal to progress from pureed to solid foods despite age-appropriate readiness.

Psychosocial Diagnoses and Factors

Psychosocial contributors often coexist with medical or skill-based impairments and can significantly affect mealtime dynamics, feeding behaviors, and caregiver-child interactions. These influences may stem from the child, caregiver, or environment.

• Avoidant/restrictive food intake disorder (or ARFID): This is characterized by restrictive eating that causes significant nutritional, weight, or psychosocial consequences without body image disturbance.[10] 

• Autism spectrum disorder: This condition frequently involves extreme food selectivity, resistance to new textures or tastes, and challenges with the social aspects of eating, leading to impaired oral intake.

• Caregiver stress or mental health disorders: This includes postpartum depression and anxiety.

• Child behavioral concerns: This includes oppositional behavior, sensory aversions, and temper tantrums during mealtimes.

• Trauma or negative feeding experiences: This includes prior choking episodes or a history of being force-fed.

• Attachment difficulties: This is often related to foster care or adoption settings.

• Environmental factors: This includes inconsistent routines and limited access to food or nurturing.

Epidemiology

PFDs affect a significant number of children in the United States, with prevalence estimates varying based on the population studied and the diagnostic criteria applied. Research suggests that 5% to 20% of children may show signs and symptoms of feeding disorders. A nationwide study in the United States reported that among children aged 5 or younger, the prevalence of PFD was approximately 32 to 34 per 1000 child-years in publicly insured populations and 21 per 1000 child-years in privately insured cohorts.[11] 

Certain populations are at notably higher risk. Children born preterm or with low birth weight are at increased risk for feeding difficulties, as are those with developmental disabilities—up to 80% of whom experience feeding problems.[12] The severity of these disorders often correlates with the degree of intellectual disability.[13] Children with chronic medical conditions, such as gastrointestinal disorders or neurological impairments, also have increased rates of PFDs, as do those from lower socioeconomic backgrounds.

Histopathology

In most cases, children with feeding disorders do not require biopsy or histopathological evaluation for diagnosis or treatment. However, there are notable exceptions where tissue sampling is essential to identify underlying organic pathology. For instance, endoscopy with biopsy is often necessary for diagnosing conditions such as eosinophilic esophagitis, which is characterized by dense eosinophilic infiltration of the esophageal squamous epithelium, along with basal cell hyperplasia, squamous cell acanthosis, and eosinophilic abscesses.[5] In suspected cases of Hirschsprung disease—especially with a history of constipation since birth—a rectal suction biopsy is essential, as the hallmark histological finding is the absence of ganglion cells in the submucosal and myenteric plexuses.[3][4][14]

History and Physical

In some cases of PFDs, an underlying diagnosis has already been established, and the history and physical examination are used to assess current functional status and inform treatment planning. In other cases, when the diagnosis is unclear, clinicians must rely on a comprehensive history and physical examination to formulate a provisional diagnosis and guide further evaluation and management. A comprehensive history and physical examination assessment should address all 4 functional domains—medical, nutritional, feeding skills, and psychosocial or behavioral.

For infants, the medical and nutritional history should include prenatal and birth details, including maternal health conditions, labor and delivery complications, mode of delivery, gestational age, congenital anomalies, respiratory or neurological disorders, prior hospitalizations, and any use of feeding tubes or specialized formulas. The feeding skills history should evaluate developmental milestones related to feeding (eg, transitioning from purees to solids), oral-motor coordination, and any history of choking, vomiting, or regurgitation, which may suggest an anatomic obstruction or motility disorder. Food refusal may be a sign of food allergy, food intolerance, or sensory aversion. A caregiver's history is also vital, focusing on the type of feeding, techniques, and positioning used while feeding the infant.[9]

Clinicians should assess the development and behavior of older children in both home and school settings. Key areas to explore include mealtime behaviors, such as temper tantrums and food refusal, as well as emotional and psychiatric symptoms. In adolescents, it is crucial to evaluate their perceptions of weight and body image, eating patterns, and the presence of disordered eating behaviors, including binge eating, restrictive intake, and excessive exercise.[15] For children of all ages, a thorough psychosocial history should examine caregiver-child interactions during meals, family dysfunction or mental health issues, and environmental stressors such as inconsistent routines or food insecurity.

The physical examination for PFDs should be comprehensive and systematic, assessing all major body systems. Growth parameters, including height, weight, and head circumference, are essential for assessing nutritional status. Clinicians should observe for dysmorphic features or craniofacial abnormalities, such as cleft palate, micrognathia, or facial asymmetry, and evaluate the choanae and oral cavity for structural anomalies. Oral-motor dysfunction may be indicated by an abnormal tongue size or tone, as well as poor coordination during swallowing. Signs of malnutrition, such as low weight-for-age, muscle wasting, or skin changes, should be documented. The abdominal exam may reveal tenderness, altered bowel sounds, or palpable masses (eg, an olive-shaped mass suggestive of pyloric stenosis in infants). A neurological assessment, which includes evaluating muscle tone, strength, and coordination, can help identify neurological conditions such as cerebral palsy or stroke.[16] 

In all cases of PFDs, a detailed history and physical examination are essential for evaluating the child’s functional status across the medical, nutritional, feeding skill, and psychosocial domains. Whether confirming existing diagnoses or uncovering new ones, this comprehensive assessment helps clinicians identify contributing factors, prioritize diagnostic testing, and develop individualized management strategies.

Evaluation

Based on pertinent history and physical examination findings, the following diagnostic tests assist clinicians in diagnosing the cause and severity of PFDs: 

• Modified barium swallow study (MBSS) or a videofluoroscopic swallow study (VFSS) is used primarily to assess for obstruction, aspiration, or dysphagia.[17]
• Esophageal manometry helps differentiate primary from secondary causes of esophageal dysphagia.
• Endoscopic procedures evaluate the pharynx and larynx during the swallowing of food.
• Food allergy testing helps determine the presence of food allergies.[18] 
• Head computed tomography (CT) is used when a stroke is suspected as the underlying cause.
• Laboratory studies assess nutritional status and detect possible deficiencies or anemia.

Treatment / Management

Because feeding disorders arise from multifactorial medical and behavioral factors, management must be individualized to address all 4 functional domains—medical, nutritional, feeding skills, and psychosocial or behavioral.

• Medical management: This focuses on treating underlying or coexisting conditions such as GERD, constipation, food allergies, anatomic anomalies (eg, cleft palate or esophageal atresia), neurological disorders, or anxiety. Although there is no universal pharmacological treatment for all children with feeding disorders, medications such as acid suppressants, prokinetics, or allergy treatments may be indicated based on the child's medical diagnosis. Surgical interventions include gastrostomy tube placement, fundoplication, or repair of structural anatomical anomalies that interfere with feeding or swallowing dysfunction.

• Nutritional management: This involves regular monitoring to prevent and treat malnutrition and micronutrient deficiencies. Dietitian-guided plans are crucial for ensuring adequate caloric and nutrient intake. Some children may require supplements to address specific nutritional deficiencies, such as low iron or vitamin D levels. Growth parameters, including height, weight, body mass index (BMI), and head circumference, should be monitored at regular intervals. In cases of severe malnutrition, nasogastric or gastrostomy tube feedings may be necessary to provide sufficient nutritional support.

• Feeding skill therapy: This focuses on improving oral-motor coordination, enhancing swallowing function, and supporting the progression to age-appropriate food textures. Children with sensory aversions to foods may benefit from desensitization strategies and structured feeding programs tailored to their needs.[19] 

• Psychosocial or behavioral support: This may include interventions such as applied behavior analysis (ABA) or cognitive behavioral therapy (CBT) to increase food intake and reduce food refusal in children with autism, ARFID, anxiety, disruptive behaviors, and other mental health or neurodevelopmental conditions.[20] Positive reinforcement is a core principle of ABA therapy, where the facilitator rewards the child for demonstrating desired behaviors, increasing the likelihood of their recurrence. Another key ABA strategy involves modifying the environment or routine—for example, offering foods the child readily accepts at set times—to reduce feeding-related anxiety and aversions. Family counseling supports caregivers by addressing stress, improving feeding interactions, and establishing consistent mealtime routines.

Differential Diagnosis

The differential diagnosis of PFDs includes a wide range of medical, developmental, nutritional, and psychosocial conditions, as detailed above. PDFs are distinct from primary eating disorders such as anorexia nervosa and bulimia nervosa, which are characterized by body image disturbances and are classified separately under psychiatric diagnoses.

Prognosis

The prognosis for PFDs is generally favorable with early, intensive intervention; however, outcomes vary based on the underlying etiology, chronicity, and coexisting medical and behavioral conditions. Interprofessional treatment, including medical and nutritional management, feeding skills therapy, and behavioral therapy, significantly improves outcomes compared to single-modality approaches.[21] Children with behavioral or feeding skill dysfunction often require more time to develop healthy eating practices compared to those with feeding issues related to prematurity or underlying medical or anatomical conditions.[22]

Complications

If not identified and managed promptly, PFDs can lead to the following complications:

• Growth faltering
• Inadequate weight gain [17]
• Vitamin deficiencies (eg, scurvy)
• Malnutrition
• Cognitive delays or impairment
• Choking
• Aspiration
• Bradycardia
• Apnea
• Dependence on feeding tubes [23]
• Aversion to social gatherings involving food
• Family stress
