What does cystic fibrosis do to the body?
Cystic fibrosis is a disorder that damages your lungs, digestive tract and other organs. It's an inherited disease caused by a defective gene that can be passed from generation to generation. Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery.
What are the symptoms associated with cystic fibrosis?
Symptoms associated with cystic fibrosis: 1. Persistent coughing, at times with phlegm. 2. Wheezing or shortness of breath. 3. Very salty-tasting skin. 4. Poor growth or weight gain in spite of a good appetite.
How many people are affected by cystic fibrosis?
Learn more about steps to take for people with cystic fibrosis and those who have had lung or other solid organ transplants. Cystic fibrosis (CF) is a genetic disorder that causes problems with breathing and digestion. CF affects about 35,000 people in the United States.
What kind of disorder is cystic fibrosis?
Cystic fibrosis is a disorder that damages your lungs, digestive tract and other organs. It's an inherited disease caused by a defective gene that can be passed from generation to generation. Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices.
What is the disorder that cause cystic fibrosis?
Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). This gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn't work the way it should, a sticky mucus builds up in your body.
Is cystic fibrosis a disease or disorder?
Cystic fibrosis is an inherited disease characterized by the buildup of thick, sticky mucus that can damage many of the body's organs. The disorder's most common signs and symptoms include progressive damage to the respiratory system and chronic digestive system problems.

Cystic fibrosis is an inherited disease characterized by an abnormality in the glands that produce sweat and mucus. Cystic fibrosis affects various organ systems in children and young adults, including the respiratory system, digestive system and reproductive system.
Is cystic fibrosis a single gene disorder?
Some genetic diseases, such as cystic fibrosis, are caused by mutations in a single gene.
Why is cystic fibrosis considered a disorder of the cell membrane?
When the protein is not working correctly, chloride — a component of salt — becomes trapped in cells. Without the proper movement of chloride, water cannot hydrate the cellular surface. This leads the mucus covering the cells to become thick and sticky, causing many of the symptoms associated with cystic fibrosis.
What is fibrosis disease?
Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly.
Is cystic fibrosis a chronic lung disease?
Cystic fibrosis is a disease that causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. It is one of the most common chronic lung diseases in children and young adults. It is a life-threatening disorder.
Which disorders are autosomal recessive?
Examples of autosomal recessive disorders include cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.

How is CF inherited?
CF is inherited in an autosomal recessive manner. [4] [1] [5] This means that to have CF, a person must have a mutation in both copies of the CFTR gene in each cell. People with CF inherit one mutated copy of the gene from each parent, who is referred to as a carrier.
Who funds the Cystic Fibrosis Research Program?
The Cystic Fibrosis Research Program is funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to support investigator-initiated research grants encompassing both fundamental and clinical studies of the etiology, molecular pathogenesis, pathophysiology, diagnosis, and treatment of cystic fibrosis and its complications.
Can mucus cause cysts in the lungs?
Over time, mucus buildup and infections can lead to permanent lung damage, including the formation of scar tissue (fibrosis) and cysts in the lungs. Mucus can also block the digestive tract and pancreas, leading to digestive problems. [1] Last updated: 5/23/2017.
What are the symptoms of cystic fibrosis?
People who are not diagnosed until adulthood usually have milder disease and are more likely to have atypical symptoms, such as recurring bouts of an inflamed pancreas (pancreatitis), infertility and recurring pneumonia. People with cystic fibrosis have a higher than normal level of salt in their sweat.
When can cystic fibrosis be diagnosed?
In the U.S., because of newborn screening, cystic fibrosis can be diagnosed within the first month of life, before symptoms develop. But people born before newborn screening became available may not be diagnosed until the signs and symptoms of CF show up.
What causes a bronchial tube to be scarred?
Cystic fibrosis is one of the leading causes of bronchiectasis, a chronic lung condition with abnormal widening and scarring of the airways (bronchial tubes). This makes it harder to move air in and out of the lungs and clear mucus from the bronchial tubes. Chronic infections.
Why do cystic fibrosis patients have dehydration?
Electrolyte imbalances and dehydration. Because people with cystic fibrosis have saltier sweat, the balance of minerals in their blood may be upset. This makes them prone to dehydration, especially with exercise or in hot weather.
What is the mutation in the cystic fibrosis transmembrane conductance regulator?
In cystic fibrosis, a defect (mutation) in a gene — the cystic fibrosis transmembrane conductance regulator (CFTR) gene — changes a protein that regulates the movement of salt in and out of cells. The result is thick, sticky mucus in the respiratory, digestive and reproductive systems, as well as increased salt in sweat.
Why are men with cystic fibrosis infertile?
Almost all men with cystic fibrosis are infertile because the tube that connects the testes and prostate gland (vas deferens) is either blocked with mucus or missing entirely. Certain fertility treatments and surgical procedures sometimes make it possible for men with CF to become biological fathers.
Why is it so hard to breathe in cystic fibrosis?
In cystic fibrosis, the airways fill with thick, sticky mucus, making it difficult to breathe. The thick mucus is also an ideal breeding ground for bacteria and fungi.

Does carrier screening include CF mutations?
However, the carrier screening offered to all women does not include all possible CF mutations. Because CF sometimes runs in families, if you have a family history of CF and decide to get screened, talk to your doctor to make sure that you are tested for the right mutation.
Can you have CF with only one copy of the CFTR gene?
A person must have mutations in both copies of the CFTR gene to have CF. This means that parents who each have a mutation in only one copy of the CFTR gene, and therefore do not have the disorder themselves, can together have a child with CF. Current recommendations. external icon.
What is cystic fibrosis?
Cystic fibrosis (CF) is an inherited life-threatening disease that affects many organs. It causes changes in the electrolyte transport system causing cells to absorb too much sodium and water. CF is characterized by problems with the glands that make sweat and mucus. Symptoms start in childhood. On average, people with CF live into their mid to late 30.
What organ system does cystic fibrosis affect?
Cystic fibrosis affects various organ systems in children and young adults, including the respiratory system, digestive system and reproductive system.
How does CF affect the gastrointestinal (GI) system?
CF mainly affects the pancreas. The pancreas secretes substances that aid digestion and help control blood sugar levels.
How does CF affect the reproductive system?
Most males with CF have blockage of the sperm canal. This is called congenital bilateral absence of the vas deferens (CBAVD). This results from the thick secretions clogging the vas deferens and keeping them from developing properly. It causes infertility because sperm can't travel out of the body. There are some newer techniques that allow men with cystic fibrosis to have children. These should be discussed with your healthcare provider. Women also have an increase in thick cervical mucus that may lead to a decrease in fertility, although many women with CF are able to have children.
