Prolonged jaundice may be observed in newborns. Intestinal obstruction and a salty taste on the skin (especially when kissed) can be among the symptoms of cystic fibrosis. During infancy, growth retardation, foul-smelling and greasy stools, and recurrent respiratory tract infections may occur. Approximately 10% of patients diagnosed with cystic fibrosis may experience meconium ileus (delayed or absent defecation) at birth.
