Overview

Infantile hypertrophic pyloric stenosis must be differentiated from other diseases that cause vomiting, poor feeding and dehydration, such as adrenal insufficiency, gastroenteritis, UTI, Inborn errors of metabolism and acute renal failure.

Differentiating Infantile Pyloric stenosis from Other Diseases

Pyloric stenosis must be differentiated from other diseases, such as:

• Adrenal insufficiency
• Gastroenteritis
• Inborn errors of metabolism
• Urinary tract infections and Pyelonephritis
• Acute renal failure
