Definition: A congenital metabolic disorder affecting the exocrine glands, inherited as an autosomal trait. The secretions of exocrine glands are abnormal, resulting in excessively viscid mucus production which causes obstruction of passageways (including pancreatic and bile ducts, intestines, and bronchi). The sweat sodium and chloride content are increased. Symptoms usually appear in childhood and include meconium ileus, poor growth despite good appetite, malabsorption and foul bulky stools, chronic bronchitis with cough, recurrent pneumonia, bronchiectasis, emphysema, clubbing of the fingers, and salt depletion in hot weather.
