How to differentiate pyloric stenosis from adrenal insufficiency?
In pyloric stenosis there is hypochloremic metabolic alkalosis; low Na, low cl, normal K (total body K is low); high pH , high CO2, high HCO3 (> 30 mEq/dL).
In adrenal insufficiency, patients have vomiting, but no palpable abdominal mass and there is presence of metabolic acidosis, high serum K, low serum Na, and elevated urinary Na excretion.
