Cystic fibrosis is a disease people are born with. It makes body fluids thick and sticky. These sticky fluids clog up the lungs, digestive system, and many other organs. Children have many health problems, such as difficulty breathing, lung infections, and poor growth. Cystic fibrosis runs in families. This disease is more common in white people.
Cystic fibrosis happens when both parents pass on a defective gene to their child
The defective gene causes body fluids in the lungs, liver, pancreas, and digestive system to be thicker and stickier than usual
Symptoms usually start in babies or young children and include throwing up, not gaining weight, and coughing
Doctors test blood and sweat, and do genetic testing to know if your child has cystic fibrosis
Doctors give medicine to help with breathing, infections, and digestion
About half of people with cystic fibrosis live past age 40
Cystic Fibrosis: Not Just a Lung Disease
Cystic fibrosis happens when a baby inherits two defective copies of a certain gene—one copy from each parent. The parents may not know they carry a defective copy of this gene. People who carry one defective copy of the gene are called carriers. Carriers have no symptoms of cystic fibrosis.
If you're trying to get pregnant, doctors can do blood tests to see if you and your partner are carriers. If you both carry the gene for cystic fibrosis, then your baby has a 1 in 4 chance of getting cystic fibrosis.
The defective genes cause body fluids to be thick and sticky instead of thin and flowing easily. The thick, sticky fluids clog up passageways in the lungs, pancreas, and intestines. The clogged passageways cause problems with breathing, getting energy from food, and passing stool (poop).
Newborn babies who have cystic fibrosis may:
Breathing symptoms start with:
After many years of breathing problems, your child may have long-term lung damage, which can cause:
Digestive symptoms occur because a child with cystic fibrosis can't digest and absorb food and vitamins. At first your child will have:
After a few years, digestive problems get worse and your child may have bad-smelling, oily poop (stool) and lose weight.
Cystic fibrosis can cause other health problems, such as:
In the United States, doctors do a blood test for cystic fibrosis when your baby is born. To know for sure, doctors will do a test on your baby’s sweat. They will also test the blood to see if your baby has the cystic fibrosis gene.
Doctors may do other tests to see if cystic fibrosis has caused problems with other organs, such as the digestive system or lungs.
To help with breathing, doctors may:
A child with a very bad lung infection will need treatment in a hospital. Your child may need to be on a breathing machine. A breathing machine lets the lungs rest so they can heal better.
Lung transplantation may be an option if your child's lungs are very damaged.
Children with cystic fibrosis can have problems taking in nutrients from food. To make sure your child gets enough energy and nutrients from food, doctors may:
To help with breathing and nutrient absorption, doctors may also give your child a new medicine that helps your child's defective gene work better.
A person with cystic fibrosis may have constipation or blocked intestines. Medicines can help with constipation. The medicine may be one that your child drinks or one that you can place in your child's anus (where poop comes out) as an enema.
A child who has diabetes Diabetes Mellitus (DM) in Children and Adolescents Diabetes mellitus is a disorder in which blood sugar (glucose) levels are abnormally high because the body does not produce enough insulin or fails to respond normally to the insulin produced... read more will need to be given insulin. Limiting sugar in the diet is also important.
Sometimes, doctors may do surgery to:
Surgery may also be done if your child needs a liver or lung transplant. A transplant may be needed if your child's liver or lungs are badly damaged. With a transplant, a failing liver or lung is replaced with a healthy one from a donor.
