Cystic fibrosis is a genetic disease characterized by the production of thick and sticky mucus in the lungs, digestive system, and other organs, due to the dysfunction of a protein called CFTR. This condition causes all secretions in the body to be dehydrated, thick, and dense, thereby losing their fluidity. These secretions, accumulating in the respiratory tracts, liver, pancreas, and intestines, lead to blockages, recurrent infections, and over time, serious organ damage.

Cystic fibrosis is an autosomal recessive inherited disease. This means that for the disease to appear in a child, both the mother and the father must be carriers of the cystic fibrosis gene. If only one parent is a mutation carrier, the child will not have cystic fibrosis, but can be a carrier.

The disease shows distinct symptoms, especially in the respiratory and digestive systems. Key respiratory symptoms include chronic productive cough, wheezing, shortness of breath, nasal congestion, and frequent lung infections. Digestive symptoms manifest as foul-smelling stools, difficulty gaining weight, and impaired bowel movements.

The primary goal in cystic fibrosis treatment is to improve the function of the respiratory tract. In this context, various treatment approaches are applied to control lung infections, thin mucus, and keep the airways open.
