Things That Can Go Wrong
With the Lungs and
Respiratory System
Focus on Teen Health
Many factors — including
genetics, pollutants and irritants,
and infectious diseases — can
affect the health of your lungs
and respiratory system and
cause respiratory problems.
Problems of the respiratory
system that can affect people
during their teen years include:
ASTHMA
• Over 20 million people have asthma in the
United States
• It is the number-one reason that kids and teens
chronically miss school
• Asthma is a long-term, inflammatory lung
disease
• It causes airways to tighten and narrow when a
person with the condition comes into contact
with irritants such as cigarette smoke, dust, or
pet dander.

COMMON COLD
• Colds are caused by over 200 different
viruses that cause inflammation in the
upper respiratory tract.
• The common cold is the most common
respiratory infection.
• Symptoms may include a mild fever,
cough, headache, runny nose, sneezing,
and sore throat.
BRONCHITIS
• Although bronchitis doesn't affect most
teens, it can affect those who smoke.
• In bronchitis, the membranes lining the
larger bronchial tubes become inflamed
and an excessive amount of mucus is
produced.
• The person with bronchitis develops a bad
cough to get rid of the mucus.
PNEUMONIA
• Pneumonia is an inflammation of the
lungs, which usually occurs because of
infection with a bacteria or virus such as
influenza and Streptococcus pneumoniae
• Pneumonia causes fever, inflammation of
lung tissue, and makes breathing difficult
because the lungs have to work harder to
transfer oxygen into the bloodstream and
remove carbon dioxide from the blood.
CYSTIC FIBROSIS
• CF is an inherited disease affecting the
lungs.
• CF causes mucus in the body to be
abnormally thick and sticky.
• The mucus can clog the airways in the
lungs and make a person more likely to
get bacterial infections.

SLEEP APNEA
Breathing stops or gets very shallow while you
are sleeping.
• The most common type is obstructive sleep
apnea. During sleep, enough air cannot flow into
your lungs. When this happens, the amount of
oxygen in your blood may drop. Normal breaths
then start again with a loud snort or choking
sound.
• Untreated sleep apnea can increase the chance
of having high blood pressure and even a heart
attack or stroke. Untreated sleep apnea can also
increase the risk of diabetes and the risk for
work-related accidents and driving accidents.

EMPHYSEMA
• Emphysema is a type of chronic obstructive
pulmonary disease (COPD) involving damage to
the air sacs (alveoli) in the lungs. As a result,
your body does not get the oxygen it needs.
• Emphysema makes it hard to catch your breath.
You may also have a chronic cough and have
trouble breathing during exercise.
• The most common cause is cigarette smoking
