    Cystic Fibrosis

    What Is Cystic Fibrosis?

    Cystic fibrosis is a disease that changes how your body makes mucus and sweat. It affects how well your lungs, digestive system, and some other body parts work. It’s caused by a flawed gene.

    If you have cystic fibrosis, you may have mucus that’s too thick or sweat that’s too salty. If heavy mucus clogs your lungs, it’s hard to breathe. It can also block your pancreas, an organ in your belly, so you can’t digest your food as well. The disease may make you sweat away too much of the salt your body needs to work well.
