Which metabolic abnormality is seen in congenital hypertrophic pyloric stenosis?
Ans. is 'b' i.e., Metabolic Alkalosis o Repetitive vomiting leads to hypochloremic, hypokalemic metabolic alkalosis. The urine is alkaline initially buteventually it becomes acidic (paradoxical aciduria)Cause of paradoxical aciduriao Initially the kidney compensate for metabolic alkalosis by reabsorbing hydrogen and chloride ions in exchange for sodium, potassium and bicarbonate. But gradually as the body stores of sodium and especially potassium become depleted, kidney starts retaining these ions in exchange of hydrogen ions, thus the urine becomes acidic and metabolic alkaline state is further aggravated.
