Back to genetics
Unfortunately, cystic fibrosis is a hereditary disease. Two adults with cystic fibrosis are extremely likely to produce a child with the disease. Think carefully about if you want still want to bring a child into the world, knowing they will most likely share your illness.
If you have cystic fibrosis and your partner does not, there is still a chance that your child may develop the disease. People can carry the gene for cystic fibrosis without actually having the disease. It might be a good idea for your healthy partner to undergo cystic fibrosis carrier testing to determine the risk of your child being born with the disease.
