Cystic Fibrosis What Is Cystic Fibrosis?
Cystic fibrosis (CF) is acondition that affects a protein in the body. People who have cystic fibrosis have a faulty protein that affects the body’s cells, its tissues, and the glands that make and sweat.
Normal mucus is slippery and protects the airways, digestive tract, and other organs and tissues. Cystic fibrosis causes mucus to become thick and sticky. As mucus builds up, it can cause blockages, damage, or infections in affected organs.
Cystic fibrosis used to cause death in childhood. Survival has improved because of medical discoveries and advances in newborn screening, medicines, nutrition, and lung transplants. Nearly 40,000 children and adults in the United States and more than 100,000 worldwide are now living with cystic fibrosis. Children born between 2018 and 2022 who have cystic fibrosis are expected to live an average of 56 years. On average, half of babies born in 2021 with cystic fibrosis are expected to reach the age of 65 or older.
Some people who have cystic fibrosis have few or no symptoms, while others experience severe symptoms or life-threatening complications. The most serious and common complications of cystic fibrosis are problems with the lungs, including frequent pulmonary or respiratory , typically caused by serious lung infections.
Your healthcare provider will recommend treatments to improve lung function and prevent or manage complications. Treatment can improve your quality of life and help you live longer.
