Congenital Chloride Diarrhea

Congenital secretory diarrhea, chloride type


Type of disease: Rare conditions

Congenital chloride diarrhea is a condition characterized by large, watery stools containing an excess of chloride. Individuals have intrauterine (pre-birth) and lifelong diarrhea; infants with the condition are often premature. The excessive diarrhea causes electrolyte and water deficits, which in turn cause volume depletion, hyperreninemia (elevated levels of renin in the blood), hyperaldosteronism, renal potassium wasting, and sometimes nephropathy. Mutations in the SLC26A3 gene have been found to cause the condition. It is inherited in an autosomal recessive manner. Treatment generally focuses on the individual symptoms of the condition and typically includes taking oral supplements of sodium and potassium chloride.
