Cystic fibrosis (CF) is a complex, life-threatening, inherited disease that mainly affects your lungs and gastrointestinal system. If you have cystic fibrosis, you may find it difficult to breathe and you may have recurring lung infections. CF can also affect other organs, such as your pancreas, where it prevents the release of digestive enzymes that enable your body to absorb vital nutrients.
The majority of people with CF are diagnosed through a newborn screening, though it’s possible to be diagnosed later in life. Today, the median predicted survival age is close to 40, according to the Cystic Fibrosis Foundation.
