Cystic fibrosis is a chronic and progressive disease, usually
diagnosed in childhood, that causes mucus to become thick and
sticky. The mucus builds up and clogs passages in the lungs,
pancreas, and many other organs in the body. Early symptoms of
cystic fibrosis include abnormally salty sweat or skin and a
failure to thrive, which includes a poor appetite, lack of
energy, and weight loss during infancy. Some babies who have
cystic fibrosis are born with a blocked small intestine. Later
symptoms include coughing up mucus and a lack of energy. Adults
who have cystic fibrosis may have fertility problems. There is
no cure for cystic fibrosis. Management of the disease varies
from person to person and generally focuses on treating
respiratory and digestive problems to prevent infection and
other complications. Treatment usually involves a combination of
medicines and home treatment methods, such as respiratory and
nutritional therapies. eMedicineHealth Medical Reference from
