Learn The Facts About Cystic Fibrosis

Cystic fibrosis (CF) is a hereditary disease that affects the cells in your body that make mucus.  CF occurs when there is a mutation of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The mutation disables cells from moving chloride (a component of salt) to their surfaces.  Without the movement of chloride, cells cannot hydrate properly.  This leads to the production of mucus that is thicker and stickier than normal.

CF can result in damage to the digestive system, lungs, and other organs that utilize mucus to function.  The buildup of mucus can obstruct the ducts, tubes or passageways of these organs.

Those living with cystic fibrosis often have abnormally high levels of salt in their sweat.  Other complications or symptoms that may develop as a result of the disease include:

  • Frequent lung infections, including recurrent  pneumonia or bronchitis
  • Persistent cough with thick mucus
  • Frequent sinus infections
  • Wheezing
  • Shortness of breath
  • Nasal polyps
  • Fatigue
  • Delayed growth or puberty
  • Poor weight gain
  • Bowel movements of greasy bulky stools
  • Severe constipation
  • Male infertility

All babies born in the United States are screened for cystic fibrosis by testing small blood samples. In other cases, if someone is suspected to have CF, their doctor can order a sweat test to determine if chloride levels are normal.

Currently, there is no cure for CF. However; treatment is focused on alleviating symptoms and reducing complications. Treatment may include medications, physical therapy, pulmonary rehabilitation or surgery.
