Cystic Fibrosis
A
genetic
disorder caused by a defective
gene
(change or mutation)
View source
Cystic Fibrosis
Mucus
is stickier than usual due to faulty gene/not absorbing water into
mucus
/trapping of white blood cells in mucus
Problems
with breathing because
mucus
blocks
airways
Chest infections as pathogens e.g. bacteria get trapped in
mucus
/
airways
Persistent cough
due to inability to
clear mucus
Lack
of energy due impaired gaseous exchange/poor oxygen saturation of
blood

Biological Causes:
•A defective
gene
(change or mutation)
Impact
(symptoms) on their life/ physical/ mental health:
•mucus
is stickier than usual due to faulty gene/not absorbing water into mucus/trapping of white blood cells in mucus.
•problems
with breathing because mucus blocks airways
•chest
infections as pathogens e.g. bacteria get trapped in mucus /
Treatment
/ Lifestyle Change/ Gadget (description)
Strength
Weakness
•Steroid
treatments to reduce symptoms.
•Physiotherapy
•Oxygen
therapy
•Lung
transplant
•Antibiotics
to treat infections.
•Regular
monitoring – use of peak flow meter.
•Diet
– well balanced; – to promote maintenance of healthy weight.
•Dietary
supplements.
•Avoidance
of pollution.
Ways of monitoring:
•a
sweat
test – to measure the amount of
salt
in sweat, which will be abnormally high in someone with cystic fibrosis.
•a genetic test – where a sample of
blood
or
saliva
is checked for the faulty gene that causes cystic fibrosis.
•Physiotheraphy
