CF affects the glands, damaging many organs including the lungs, the pancreas, the digestive tract and the reproductive system. It causes a thick sticky mucus to be produced, blocking the bronchial tubes and preventing the body's natural enzymes from digesting food.The Cystic Fibrosis Association of Ireland (CFAI) is a voluntary, non-profitable, charitable organisation. It was set up in 1963 to increase knowledge and awareness of CF and to give advice and support to people with Cystic Fibrosis and their families.
