Cystic Fibrosis
















What is Cystic Fibrosis?


Cystic fibrosis (CF) is a life-threatening disorder that causes severe damage to the lungs and digestive system.An inherited condition, cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery. But in cystic fibrosis, a defective gene causes the secretions to become thick and sticky.


What causes Cystic Fibrosis?


Cystic fibrosis (CF), a defect  in a gene changes a protein that regulates the movement of salt in and out of cells.  The affected gene, which is inherited from a child's parents, is a recessive gene. Children need to inherit one copy of the gene from each parent in order to have the disease. If children inherit only one copy, they won't develop cystic fibrosis, but will be carriers and possibly pass the gene to their own children.


Diagnosis of Cystic Fibrosis?


Cystic fibrosis signs and symptoms vary, depending on the severity of the disease. Even in the same person, symptoms may worsen or improve as time passes. In some children, symptoms begin during infancy. Other people may not experience symptoms until adolescence or adulthood.
