Cystic Fibrosis Cause
Nearly half the children with cystic fibrosis are diagnosed when they are taken to the doctor because of frequent coughing, wheezing and respiratory tract infections. The coughing can be accompanied by gagging, vomiting and disturbed sleep.Over time, the chest becomes barrel-shaped. The lack of oxygen causes the fingers to be bigger at the tips. The area under the fingernails looks bluish.Because of the digestive problems that cystic fibrosis creates, a variety of nutritional complications can develop. These include night blindness, rickets, anemia (a lack of iron in the blood) and bleeding disorders. About 15% of adults with cystic fibrosis develop diabetes that requires treatment with insulin.
