Hi there, Cystic fibrosis is a condition where the lungs of the person are affected and he/she could have breathing difficulties and repeated infections in the chest, he/she may also have digestive enzyme deficiency as it can also affect the pancreas. This is a genetic condition and the child is only affected if both parents are carriers or patients. A carrier, such as you, do not have symptoms of the disease but can give the disease to his/her kid if the other partner is also a carrier. You need to get your partner checked if he is a carrier of the defective cystic fibrosis gene or not. If he is not a carrier then there is no risk of your child developing cystic fibrosis. If he is a carrier there is a 1/4 that your baby may have cystic fibrosis, if found positive you need to meet with a Obstetrician who can do amniocentesis immediately. He suffering from cystic fibrosis is very unlikely as most men with cystic fibrosis are infertile and are unable to father a kid. Hope this helps. Regards.
