Cystic Fibrosis By Tu Trinh Vu
What is Cystic Fibrosis? It is a genetic disease that is passed
down through families that causes a thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body.
The Cause. It is caused by a defective gene where
it does not produce the protein for the salt channels, resulting with the buildup of mucus.
Prevention? It is genetic, therefore there is no
prevention of this disease.
Who is Affected. It is most common in Caucasians, and
most is deadly. 1 in 29 Caucasians have the Cystic
Fibrosis Gene.
Diagnosis. Blood Test Chest X-ray Lung Function Test Fecal Fat Test Sweat Chloride Test
How the System Normally Works.
Air goes down trachea
& bronchi
Air Comes through
mouth/nose.
Ends in alveoli
Air (O2) moves form
alveoli to blood.
Watery mucus layer helps trap & move debris.
Salt channels maintain
layer.

How the Disease Affects Homeostasis
Thick mucus builds up in lungs, and eventually
causing problems in
digestive tract, and other areas.
Genetic mutation causes salt channels to
unevenly distribute salt
and water across the layer of cells.
Salt channels maintain
layer.
Symptoms. In Newborns:
› Delayed growth› Failure to gain weight normally› No bowel movements in first 24-48 hours› Salty-tasting skin
Symptoms. In the Bowel Functions:
› Belly pain from severe constipation› Increased gas & bloating› Nausea & loss of appetite› Stool, that are pale or clay colored, foul
smelling, and have mucus.
Symptoms. Lungs & Sinuses
› Coughing› Increases Mucus in the sinuses/lungs
Symptoms. Weight loss Pneumonia Infertility
Treatment. Lungs:
› Antibiotics to prevent & treat lung & sinus infections
› Inhaled medicines › DNA enzymes therapy› Flu Vaccine› Lung Transplant› Oxygen Therapy
Treatments. Bowels:
› Special diet high in protein & calories› Pancreatic enzymes to help absorb fats &
proteins› Vitamin supplements
