Cystic Fibrosis

Cystic fibrosis is a genetic disorder that affects the lungs, pancreas, and other organs. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator or (CFTR). This affects the movement of salt and water in and out of cells.

When the CFTR protein is not working correctly, it leads to the production of sticky and thick mucus in different organs. Thus causing a range of symptoms and complications.

Cystic Fibrosis Causes

Cystic fibrosis is caused by mutations in the CFTR gene, which encodes a protein that regulates the passage of salt and water into and out of cells. These mutations cause the synthesis of faulty CFTR protein. Thus, resulting in the accumulation of thick and sticky mucus in a variety of organs, including the following:

·      Lungs

·      Pancreas

·      Intestines

CF is an inherited disease. This means that it is passed down from parents to their children through genes. 

Symptoms of Cystic Fibrosis

Common signs and symptoms include:

  1. Persistent Cough: A chronic cough that produces thick and sticky mucus is a hallmark symptom of cystic fibrosis.
  2. Frequent Lung Infections: People with CF are prone to recurrent lung infections such as pneumonia and bronchitis.
  3. Shortness of Breath: Difficulty breathing, especially during physical exertion, is common in individuals with cystic fibrosis.
  4. Wheezing: Wheezing occur due to airway obstruction.
  5. Poor Growth: Children with CF may experience poor growth and weight gain despite a normal appetite.
  6. Digestive Problems: CF can lead to digestive problems, including:
    • abdominal pain
    • bloating
    • diarrhea
    • foul-smelling stools
  7. Salty Skin: People with CF may have salty-tasting skin due to the high concentration of salt in their sweat.

Who is at Risk for Cystic Fibrosis?

Cystic fibrosis is an inherited disorder, so family history is the most significant risk factor. Cystic fibrosis can affect any race, however it is most common in white people of North European heritage.

Complications of Cystic Fibrosis

Cystic fibrosis can cause a range of complications, including:

  • Damage to the airways (bronchiectasis)
  • Respiratory failure
  • Chronic infections
  • CF-related diabetes
  • Osteoporosis
  • Infertility
  • Liver disease

How is Cystic Fibrosis Diagnosed?

Diagnosing cystic fibrosis is a multistep process, and should include a genetic or carrier test, sweat test, and lung function test. A sweat test is the most common way to diagnose cystic fibrosis. It measures the amount of salt in sweat, which is higher in people with CF. A lung function test measures how well the lungs are working.

How is Cystic Fibrosis Treated?

There is no cure for cystic fibrosis. However, available treatments can help manage the symptoms and prevent complications. This includes:

  • Airway clearance techniques to help clear mucus from the lungs
  • Medications to help fight infections and thin mucus
  • Nutritional therapy to ensure proper growth and development
  • Surgery to remove blockages or damaged tissue
  • Lung transplantation in severe cases

Cystic fibrosis is an inherited disorder that affects the lungs, pancreas, and other organs. It is caused by mutations in the CFTR gene, which affects the movement of salt and water in and out of cells. The symptoms of cystic fibrosis can vary widely, and the disease can cause a range of complications. 

Although there is no cure for cystic fibrosis, treatments can help manage the symptoms and prevent complications. With proper care and management, people with cystic fibrosis can lead healthy and fulfilling lives.
