What is a major characteristic of Cystic fibrosis?

Cystic fibrosis is characterized primarily by the production of thick, sticky mucus that can cause complications in various organs. This mucus buildup primarily affects the lungs and the pancreas, but it can also impact other organs, such as the liver and intestines. The thickened mucus obstructs airways, leading to respiratory issues and making it difficult for the body to digest food properly.

While the condition does have significant effects on the respiratory system, it is not limited to just that system, which is why stating that it affects only the respiratory system is inaccurate. Neurological symptoms are not a primary characteristic of cystic fibrosis; the primary challenges involve respiratory and digestive issues. Furthermore, while cystic fibrosis can lead to life-threatening complications, advancements in treatment have improved the life expectancy of individuals with this condition, meaning that it is not always fatal in childhood. Thus, the thickening and buildup of mucus is a defining and major characteristic of cystic fibrosis.
