It’s a rare but serious disease that attacks the lungs and digestive system and destroys them little by little.
Cystic fibrosis is not contagious. It’s inherited from parents who transmit a defective gene.
In the US, about 1000 babies are born with the disease every year.
The disease makes mucus thick and glue like. Mucus is the slimy stuff you spit out sometimes when you have a cold.
The mucus in patients with cystic fibrosis, is too thick: it stops them breathing properly and can lead to infections. It also stops them digesting properly.
Patients cough a lot, feel very tired and suffer from bad tummy pains.
We don’t yet know how to cure this disease. But treatment is getting better!
