When do they diagnose cystic fibrosis

It's caused by a faulty gene that affects the movement of salt and water in and out of cells. This, along with recurrent infections, can result in a build-up of thick, sticky mucus in the body's tubes and passageways — particularly the lungs and digestive system.

A person with cystic fibrosis is born with the condition. It's not possible to "catch" cystic fibrosis from someone else who has it. To be born with cystic fibrosis, a child has to inherit a copy of the faulty gene from both of their parents.

This can happen if the parents are "carriers" of the faulty gene, which means they don't have cystic fibrosis themselves. Cystic fibrosis tends to get worse over time and can be fatal if it leads to a serious infection or the lungs stop working properly. Currently, about half of people with cystic fibrosis will live past the age of Children born with the condition nowadays are likely to live longer than this.

Support is available to help people with cystic fibrosis live as independently as they can and have the best possible quality of life. If you or your child has cystic fibrosis, your clinical team will ask you if you consent to being on the UK Cystic Fibrosis Registry. This is a secure anonymous registry sponsored by the Cystic Fibrosis Trust that records health information on people with cystic fibrosis.

The registry helps scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time. This allows the different parts of our body to make an adequate supply of thin, freely flowing mucus. Mucus helps protect the body from dirt, bacteria, and viruses that can be inhaled.

Individuals with cystic fibrosis CF are unable to move chloride ions and water throughout their body. As a result, the lungs, pancreas, and other organs produce mucus that is unusually thick and sticky. This mucus is unable to protect the body. Therefore, mucus clogs the body's airways and glads and reduces its ability to fight infections. CF is an autosomal recessive genetic condition. This means that a child must inherit two copies of the non-working gene for CF, one from each parent, in order to have the condition.

The parents of a child with an autosomal recessive condition each carry one copy of the non-working gene, but they typically do not show signs and symptoms of the condition. While having a child with CF is rare, when both parents are carriers, they can have more than one child with the condition. Learn more about autosomal recessive inheritance. Support groups can help connect families who have a child or other family member affected with cystic fibrosis with a supportive community of people who have experience and expertise in living with the condition.

These organizations offer resources for families, affected individuals, health care providers, and advocates:. When your child reaches school age, you can provide teachers and school administration with this resource specifically for children with cystic fibrosis. Because CF is a genetic condition , you may want to talk with a genetics specialist. A genetic counselor or geneticist can help you understand the causes of the condition, discuss genetic testing for CF, and understand what this diagnosis means for other family members and future pregnancies.
