Cystic Fibrosis

Cystic fibrosis is a serious disorder that causes severe lung harm and nutritional deficits. An inherited condition, cystic fibrosis affects the cells that manufacture mucus, sweat and digestive juices. Usually, these secretions are thin and slippery, but in cystic fibrosis patients, a defective gene causes the secretions to become thick and sticky. Rather than performing as a lubricant, the secretions stop up tubes, ducts and passageways, particularly in the pancreas and lungs. Cystic fibrosis occurs regularly in white people of northern European ancestry, happening in about one out of three thousand live births. Formerly the majority of people with cystic fibrosis died in their teens. Enhanced screening and treatments currently permit a lot of people with cystic fibrosis to live into their fifties or even longer (Cystic fibrosis, 2011).

A defect in the CFTR gene causes cystic fibrosis. This gene produces a protein that manages the progress of salt and water in and out of the body's cells. In people who have cystic fibrosis, the gene produces a protein that doesn't work correctly. This leads to thick, sticky mucus and very salty sweat. Research proposes that the CFTR protein also influences the body in other manners. This might assist in explaining other symptoms and difficulties of cystic fibrosis. More than a thousand recognized defects can influence the CFTR gene. What kind of defect a person has may control how severe cystic fibrosis is. Additional genes also might play a role in how harsh the disease is (Cystic Fibrosis, 2011).

The thick and sticky mucus connected with cystic fibrosis blocks the tubes that carry air in and out of a person's lungs. This can cause:

unrelenting cough panting frequent lung infections recurring sinus infections

The thick mucus can also block tubes that transport digestive enzymes from ones pancreas to ones small…
