Failure to thrive (FTT) is a condition characterized by inadequate physical growth in infants and children. It occurs when a child’s weight or rate of weight gain is significantly below that of other children of similar age and sex.

Symptoms

• Weight below the 3rd percentile on standard growth charts or 20% below ideal weight for height.
• Decelerated or arrested growth, including height and head circumference in severe cases.
• Delayed developmental milestones, affecting physical, mental, and social skills.
• Irritability and reduced energy levels.
• Poor social engagement, such as lack of age-appropriate responses like smiling or making eye contact.

Causes

FTT can result from various factors and is commonly classified into the following categories:

• Inadequate caloric intake:
  • Poverty or food insecurity.
  • Breastfeeding challenges or insufficient breast milk.
  • Improper formula preparation.
  • Feeding difficulties due to developmental delays or oral-motor issues.
• Malabsorption or increased caloric needs:
  • Chronic gastrointestinal conditions such as celiac disease or cystic fibrosis.
• Metabolic disorders leading to inefficient energy utilization.
  • Chronic infections or diseases increasing caloric requirements.
• Psychosocial factors:
• Neglect or abuse impacting nutrition and emotional well-being.
• Parental factors such as depression, inadequate knowledge of nutrition, or poor feeding practices.

Diagnosis

Diagnosis involves a comprehensive approach:

• Growth chart analysis to identify trends in weight, height, and head circumference.
• Medical history review for risk factors, feeding habits, and family health.
• Physical examination to detect signs of malnutrition or underlying conditions.
• Feeding observation to assess feeding techniques and child-parent interactions.
• Laboratory tests to evaluate for infections, nutrient deficiencies, metabolic disorders, or malabsorption.
• Imaging studies, if indicated, to identify structural abnormalities.

Treatment

Treatment focuses on improving nutritional status and addressing underlying causes:

• Nutritional support:
  • High-calorie diets or fortified formulas tailored to the child’s needs.
• Feeding therapy with specialists to improve intake and correct feeding practices.
  • In severe cases, hospitalization for closely monitored feeding and nutritional rehabilitation.
• Management of underlying conditions:
  • Treating chronic illnesses like cystic fibrosis or celiac disease.
  • Addressing infections or metabolic disorders contributing to poor growth.
• Psychosocial and family support:
  • Nutritional counseling for parents to ensure proper food preparation and feeding techniques.
  • Addressing parental mental health or education gaps.
  • Intervening in cases of neglect or abuse through appropriate social services.
• Regular follow-up:
  • Monitoring growth trends, development milestones, and overall health during ongoing evaluations.
