Overview
Asthma is a condition in which your airways narrow and swell and produce extra mucus. This
can make breathing difficult and trigger coughing, wheezing and shortness of breath.
Asthma can't be cured, but its symptoms can be controlled. Because asthma often changes
over time.
Asthma is a long-term disease of the lungs. You might hear your doctor call it a chronic
respiratory disease.
Severe asthma attacks can be life-threatening.
Cause of asthma
Genetics. If a parent has asthma, you’re more likely to develop it.
History of viral infections. People with a history of viral infections during childhood are
more likely to develop the condition.
Hygiene hypothesis. This hypothesis proposes that babies aren’t exposed to enough
bacteria in their early months and years. Therefore, their immune systems don’t become
strong enough to fight off asthma and other conditions.
Early allergen exposure. Frequent contact with possible allergens and irritants may
increase your risk for developing asthma.
Asthma triggers
Illness. Respiratory illnesses such as the flu and pneumonia can trigger asthma attacks.
Exercise. Increased movement may make breathing more difficult.
Irritants in the air. People with asthma may be sensitive to irritants such as chemical
fumes, strong odors, and smoke.
Allergens. Animal dander, dust mites, and pollen are just a few examples of allergens
that can trigger symptoms.
Extreme weather conditions. Conditions such as very high humidity or low temperatures
may trigger asthma.
Emotions. Shouting, laughing, and crying may trigger an attack.
Treatment of asthma
Breathing exercises
These exercises can help you get more air into and out of your lungs. Over time, this
may help increase lung capacity and cut down on severe asthma symptoms.
Rescue or first aid treatments
These medications should only be used in the event of an asthma attack. They provide
quick relief to help you breathe again. Examples:
Inhalers
Nebulizers
