Cystic fibrosis (CF) is an inheritable progressive disease that results in a thick mucus building up in various organs, including the lungs, pancreas, liver, and intestines.
Some people who have cystic fibrosis have few or no signs or 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.
