When discussing diseases caused by mucus build-up, which condition is referred to?

Cystic Fibrosis is a genetic disorder that leads to the production of thick and sticky mucus in various organs, primarily affecting the lungs and digestive system. This condition results from mutations in the CFTR gene, which regulates salt and water transport across cell membranes. The thickened mucus can obstruct airways, trap bacteria, and create a breeding ground for infections, ultimately leading to respiratory complications and impaired lung function.

In addition to the respiratory system, cystic fibrosis can also affect the pancreas, intestines, and other organs, causing malabsorption of nutrients and other systemic issues. The characteristic mucus build-up is a hallmark of this disease, distinguishing it from other respiratory conditions that may involve inflammation or narrowing of airways but do not inherently result in the production of excessively thick mucus.
