What Is Cystic Fibrosis?
- Cystic fibrosis (CF) is a genetic condition that affects a protein in the body. People who have cystic fibrosis have a faulty protein that affects the body’s cells, tissues, and the glands that make mucus and sweat.
- Mucus is normally slippery and protects the linings of the airways, digestive tract, and other organs and tissues.
- People who have cystic fibrosis make thick, sticky mucus that can build up and lead to blockages, damage, or infections in the affected organs.
- Inflammation also causes damage to organs such as the lungs and pancreas.
- Some people who have cystic fibrosis have few or no symptoms, while others experience severe symptoms or life-threatening complications. Symptoms of cystic fibrosis depend on which organs are affected and the severity of the condition.
- The most serious and common complications of cystic fibrosis are problems with the lungs, also known as pulmonary or respiratory problems, which may include serious lung infections.
- People who have cystic fibrosis often also have problems maintaining good nutrition, because they have a hard time absorbing the nutrients from food. This is a problem that can delay growth.
