A common issue for infants that affects more males than females. As with this infant, it usually presents with vomiting right after eating as the main symptom. According to McCance andHuether (2014), the exact cause is unknown, but has been attributed to increased gastrin secretion by the mother during the final trimester of pregnancy,
administration of prostaglandin E, and even genetic predisposition with family history. Pathophysiological Process of Pyloric StenosisAccording to Ndongo, Tolefac, Tambo, Abanda, Ngowe, Fola, Dzekem, Weledji, Sosso and Minkande (2018), the enlargement and overproduction of the smooth muscle cells of the pylorus causes narrowing and encroachment by the pyloric sphincter muscle which makes it difficult foradequate movement of food through the pylorus. With the extra work being done to try and move the food through the pylorus, it becomes even more enlarged exacerbating the problem.Hallmark Signs and Diagnostic TestsThe main sign of pyloric stenosis would be the sudden, projectile vomiting after eating. According to McCance and Huether (2014), along with the projectile vomiting that usually starts around 2-3 weeks of age, the infant usually wants to eat again immediately after vomiting andconstipation is always an issue because the food never reaches the intestines as it should. If the infant continuesto vomit with feedings, then dehydration and electrolyte issues are soon to follow as well.
