Overfeeding

Basic science and pathophysiology

• A very common diagnosis that can also present with isolated regurgitation.
• Typically an infant requires 150ml/kg/day to ensure adequate growth.
• A fluid ounce is approximately 30ml.
• This is more difficult to assess in breast-fed infants but may be apparent with a careful feeding history.
• However, in both types of infant growth will be excessive.

Management

• If excessive feeding is suspected then this should be reduced to acceptable levels.
• Parents should be advised to return if:
  • Persistently projectile, haematemesis or bilious vomiting
  • New concerns (marked distress, feeding difficulties or faltering growth)
  • Persistent, frequent regurgitation beyond the first year of life
