Their parents will not usually have the condition themselves, because they will only carry one faulty gene and one that works normally. Read more about the causes of cystic fibrosis. Most cases of cystic fibrosis are now detected soon after birth through the newborn blood spot test.
This involves collecting a drop of blood from the baby's heel and testing it for abnormalities that could indicate cystic fibrosis. These tests can also be carried out in older children and adults with symptoms of cystic fibrosis who haven't been screened previously.
If you have a family history of cystic fibrosis, you can be tested to determine if you're at risk of having a child with the condition by checking if you're a "carrier" of the faulty gene that causes it. Read more about how cystic fibrosis is diagnosed. There's currently no cure for cystic fibrosis, but a number of treatments are available to help control the symptoms, prevent complications, and make the condition easier to live with.
A lung transplant may eventually be needed if the lungs become greatly damaged. Read more about treating cystic fibrosis. Eventually the condition can be fatal if it leads to a serious infection or the lungs stop working properly. The outlook for cystic fibrosis has improved considerably in recent years because of advancements in treatment, although most people with cystic fibrosis will have a shorter-than-average life expectancy.
Currently, about half of the people with cystic fibrosis will live past the age of Children born with the condition nowadays are likely to live longer than this. This helps scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time. Find out more about the register. Cystic fibrosis can cause a range of problems. The lungs and digestive system are the main areas that are affected.
Symptoms tend to start in early childhood, but sometimes they can develop soon after birth and very occasionally they may not be obvious until adulthood. Nowadays, cystic fibrosis is usually diagnosed before symptoms appear, through screening tests carried out soon after birth. Read more about screening for cystic fibrosis. The mucus can also block parts of the digestive system, which can affect how food travels through the gut and how it's broken down or absorbed. 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.
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. This means they don't have cystic fibrosis themselves, but they can have a child with the condition if their partner also carries the faulty gene. It's estimated that around 1 in every 25 people in the UK are carriers of the faulty gene that causes cystic fibrosis. Most cases are now detected soon after birth through newborn screening, but older children and adults with symptoms of cystic fibrosis who weren't screened can also have tests to check for the condition.
Tests to find out if you are a 'carrier' of the faulty gene responsible for cystic fibrosis may also be recommended for some people. A newborn blood spot test is offered to all babies in Scotland to help detect problems early on, including cystic fibrosis. When your baby is five to eight days old, a health professional will prick their heel and collect drops of blood on a special card.
The blood is then sent to a laboratory to be checked for abnormalities that could indicate cystic fibrosis. You should receive the results by the time your baby is six to eight weeks old. You will be contacted sooner if a problem is found, and you'll be asked to attend a hospital appointment.
You, your partner and any other children you have may also be tested to see if you carry the faulty gene that causes cystic fibrosis. Tests to confirm a diagnosis will be carried out if screening suggests that your child may have cystic fibrosis, or your doctor thinks you could have the condition and you haven't been screened previously. The sweat test is most commonly used, although genetic testing may be done if the sweat test result is inconclusive or to identify the specific genetic fault that's causing the condition.
This can be done using a blood test, or occasionally a special mouthwash, to collect a sample of cells. The sample is then sent to a laboratory so it can be checked for the faulty gene. Treatments are available to help reduce the problems caused by the condition and make it easier to live with, but sadly life expectancy is shortened.
Get advice about coronavirus and cystic fibrosis from the Cystic Fibrosis Trust. The build-up of sticky mucus in the lungs can cause breathing problems and increases the risk of lung infections.
Over time, the lungs may stop working properly. Mucus also clogs the pancreas the organ that helps with digestion , which stops enzymes reaching food in the gut and helping with digestion. This means most people with cystic fibrosis don't absorb nutrients from food properly and need to eat more calories to avoid malnutrition. People with the condition can also develop a number of related conditions, including diabetes , thin, weakened bones osteoporosis , infertility in males, and liver problems.
In the UK, all newborn babies are screened for cystic fibrosis as part of the newborn blood spot test heel prick test carried out shortly after they're born. If the screening test suggests a child may have cystic fibrosis, they'll need these additional tests to confirm they have the condition:. These tests can also be used to diagnose cystic fibrosis in older children and adults who didn't have the newborn test.
The genetic test can also be used to see whether someone is a "carrier" of cystic fibrosis in cases where the condition runs in the family. This test can be important for someone who thinks they may have the faulty gene and wishes to have children. The Cystic Fibrosis Trust has more information about genetic testing for cystic fibrosis. There's no cure for cystic fibrosis, but a range of treatments can help control the symptoms, prevent or reduce complications, and make the condition easier to live with.
One of the first signs of cystic fibrosis is a strong salty taste to the skin. Parents of children with cystic fibrosis have mentioned tasting this saltiness when kissing their children. The thick, sticky mucus associated with cystic fibrosis often blocks the passageways that carry air into and out of the lungs. This can cause the following symptoms:.
The abnormal mucus can also plug up the channels that carry the enzymes produced by the pancreas to the small intestine. This can result in:. This abnormal mucus builds up in various organs throughout the body, including the:.
Many different defects can affect the CFTR gene. The type of defect is associated with the severity of cystic fibrosis. The damaged gene is passed on to the child from their parents. In order to have cystic fibrosis, a child must inherit one copy of the gene from each parent. Cystic fibrosis is most common among people of Northern European descent.
The diagnosis of CF requires clinical symptoms consistent with CF in at least one organ system and evidence of CFTR dysfunction usually based on an abnormal sweat chloride test or the presence of mutations in the CFTR gene.
The immunoreactive trypsinogen IRT test is a standard newborn screening test that checks for abnormal levels of the protein called IRT in the blood. A high level of IRT may be a sign of cystic fibrosis. However, further testing is required to confirm the diagnosis. The sweat chloride test is the most commonly used test for diagnosing cystic fibrosis. It checks for increased levels of salt in the sweat.
The test is performed by using a chemical that makes the skin sweat when triggered by a weak electric current. Sweat is collected on a pad or paper and then analyzed. A diagnosis of cystic fibrosis is made if the sweat is saltier than normal. During a sputum test, the doctor takes a sample of mucus. The sample can confirm the presence of a lung infection. It can also show the types of germs that are present and determine which antibiotics work best to treat them.
A chest X-ray is useful in revealing swelling in the lungs due to blockages in the respiratory passageways. A CT scan creates detailed images of the body by using a combination of X-rays taken from many different directions.
