Overview
Most common laboratory findings consistent with the diagnosis of infantile pyloric stenosis and adult type pyloric stenosis include hypokalemia, hypochloremia, and metabolic alkalosis.
Laboratory Findings
- Laboratory findings consistent with the diagnosis of pyloric stenosis include electrolyte imbalances such as:[1]
- Hypokalemia[2]
- Hypochloremia
- Metabolic alkalosis due to loss of gastric acid (which contains hydrochloric acid and potassium) via persistent vomiting.
- Any condition with severe vomiting may present with similar findings.
