Cystic fibrosis is a genetic disorder that primarily impacts the lungs and digestive system. One of the hallmark features of cystic fibrosis is the production of thick, sticky mucus, which can obstruct the ducts of the pancreas. This obstruction prevents the release of digestive enzymes, resulting in inadequate fat digestion.

As a consequence, children with cystic fibrosis often experience fat malabsorption, leading to greasy, foul-smelling stools, known as steatorrhea. This symptom arises because undigested fats are excreted in the stool instead of being absorbed by the body. The inability to properly digest and absorb fats can also lead to nutritional deficiencies and weight loss in affected individuals.

The other options presented do not accurately reflect the common digestive issues associated with cystic fibrosis. Missing gallbladders and complete intestinal blockage are not commonly seen in these patients, while poor digestion of carbohydrates is not a primary concern; the main issue lies in fat malabsorption due to pancreatic insufficiency.
