Cystic Fibrosis (CF)



Cystic fibrosis (CF) is an inherited condition of the mucus glands. Mucus is a slippery substance the body secretes to cover and protect the lungs, digestive system, reproductive system, and other organs and tissues. CF causes the body to produce excess mucus that is abnormally thick and sticky, which can lead to a variety of health problems. If left untreated, CF can cause serious lifelong health problems that could lead to early death. However, if the condition is identified early and proper treatment is begun, many of the symptoms of CF can be controlled and individuals can live longer, healthier lives. Signs of CF usually start shortly after birth, but some may not appear right away. Early signs of CF include salty sweat, poor growth and weight gain (failure to thrive), constant coughing and wheezing, and thick mucus or phlegm.
