“Cystic fibrosis (CF) is a genetic disorder that causes problems with breathing and digestion. CF affects about 35,000 people in the United States. People with CF have mucus that is too thick and sticky, which

• blocks airways and leads to lung damage;
• traps germs and makes infections more likely; and
• prevents proteins needed for digestion from reaching the intestines, which decreases the body’s ability to absorb nutrients from food.
• Sometimes it blocks the pancreas”
