What is cystic fibrosis?

ANSWER

More than 30,000 people in the U.S. live with cystic fibrosis (CF.) Doctors diagnose about 1,000 new cases each year. CF affects the cells in your body that make mucus, sweat, and digestive fluids. Normally, these are very thin and slippery to keep systems in your body running smoothly. But if you have CF, they become thick and glue-like. This blocks tubes and ducts throughout your body. Over time, mucus builds up inside your airways. This makes breathing a struggle. The mucus traps germs and leads to infections. It can also cause severe lung damage like cysts (fluid-filled sacs) and fibrosis (scar tissue). That’s how CF got its name.
