What is Cystic Fibrosis?

Cystic Fibrosis (CF) is an inherited disease that affects the lungs and digestive system of about 30,000 children and adults in the United States (70,000 worldwide). A defective gene and its protein product cause the body to produce unusually thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections, obstructs the pancreas, and stops natural enzymes from helping the body to break down and absorb food. People with CF tend to have a lot of sinus problems.

Cystic Fibrosis Information

Symptoms

People with CF can have a variety of symptoms including:

  • Very salty-tasting skin
  • Persistent coughing (at times with phlegm)
  • Frequent lung infections
  • Wheezing
  • Shortness of breath
  • Poor growth/weight gain in spite of a good appetite
  • Frequent greasy bulky stools
  • Difficulty in bowel movements
  • Sinus issues
Diagnosis

Most people are diagnosed with CF at birth upon newborn screening, which became a nationwide standard in 2010. On occasion, someone is missed by newborn screening. A physician who sees signs and symptoms will order either a sweat test or a genetic test to confirm the diagnosis.

A sweat test is the most common test used to diagnose cystic fibrosis. A small electrode is placed on the skin (usually on the arm) to stimulate the sweat glands. Sweat is then collected and the amount of chloride, a component of salt in the sweat, is measured.

In a genetic test, a blood sample, or cells from the inside of the cheek are taken and sent to a laboratory to see if any of the various mutations of the CF gene are found. A genetic test is often used if the results from a sweat test are unclear or if more detail is needed to prescribe the best medication for the patient.
