Cystic fibrosis (CF) is an inherited disease. It causes a defect in certain cells of the lung and digestive system. The defect makes the cells produce a thick, sticky mucus. This mucus can cause:

  • Blockages in the lungs and airways
  • Problems digesting and absorbing nutrients

CF is a serious life-long condition, but the severity of the illness can vary greatly. The average life expectancy for someone with CF is about 35 years. Although, some with mild forms of CF can live to age 60 or beyond.

CF is a genetic disorder. A child with CF inherits defective genes from each parent. Parents who have the gene but do not have CF are called carriers.
