The first symptom of cystic fibrosis in an infant who does not have meconium ileus is often a delay in regaining birth weight or poor weight gain at 4 to 6 weeks of age. Inadequate amounts of pancreatic enzymes, which are essential for proper digestion of fats and proteins, lead to poor digestion in most infants with cystic fibrosis. the infant has frequent, bulky, foul-smelling, oily stools and may have a distended abdomen and small muscles. Weight gain is slow despite a normal or large appetite.
