Respiratory signs and symptoms
The thick and sticky mucus associated with cystic fibrosis clogs the tubes that carry air in and out of your lungs. This can cause:
Persistent cough
Wheezing
Repeated lung infections
Repeated sinus infections
Digestive signs and symptoms
The thick mucus can also block tubes that carry digestive enzymes from your pancreas to your small intestine. Without these digestive enzymes, your intestines can't fully absorb the nutrients in the food you eat. This can cause:
Foul-smelling, greasy stools
Poor weight gain and growth
Distended abdomen from constipation
Intestinal blockage, particularly in newborns
