Which disease is an inherited disorder of the exocrine glands characterized by persistent upper respiratory infections and foul-smelling stools?

Cystic Fibrosis is indeed the correct answer as it is a genetic disorder caused by mutations in the CFTR gene, leading to the production of thick and sticky mucus that can obstruct various organs, particularly the lungs and digestive system. This condition significantly affects the exocrine glands, which are responsible for producing secretions like saliva, sweat, and digestive enzymes.

Individuals with Cystic Fibrosis frequently experience persistent upper respiratory infections due to the mucus buildup in the respiratory tract, creating an environment conducive for bacterial growth. Additionally, the thickened mucus can interfere with the normal function of the pancreas, inhibiting the release of digestive enzymes, which often leads to malabsorption of nutrients and results in foul-smelling stools. This characteristic symptom is indicative of the digestive complications associated with the disease.

Asthma is primarily a chronic inflammatory disease of the airways characterized by airway hyperreactivity, resulting in wheezing and difficulty breathing, rather than persistent infections or digestive issues. Acid reflux involves the backflow of stomach acid into the esophagus and does not typically cause upper respiratory infections or affect the exocrine glands in the manner associated with Cystic Fibrosis. Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) primarily
