Explanation
•Regurgitation occurs almost immediately after feeding or when the infant is laid down after a feeding. If the reflux is large, the infant does not retain sufficient calories and will fail to thrive.
•Gastroesophageal reflux is a neuromuscular disturbance in which the lower esophageal sphincter and the lower portion of the esophagus are lax and allow regurgitation of gastric contents into the esophagus.
•Projectile vomiting is seen more commonly in pyloric stenosis. Currant jelly stools are characteristics of intussusceptions. Steatorrhea occurs in malabsorption disorders.
