With pyloric stenosis, vomiting becomes projectile, and a small olive-sized mass is palpable in the RUQ; the infant is usually hungry again soon after vomiting, and because little or no food is reaching the intestines, the infant has fewer, smaller stools. The child fails to thrive and has signs of dehydration. These signs are not associated with GERD. Regurgitation can be present with either disease.
