Asthma is a very common inflammatory condition of the airways characterized
by increased mucus secretion, bronchial muscle contraction, and swelling of
the mucosa. All these narrow down the airway which decreases the airflow.
The inflammation is caused by irritants present in the air. This can be in
the form of cigarette smoke, paint fumes, polluted air, and aerosol sprays.
When any of these mix with the air and inhaled, the hypersensitive airways
over-react producing the signs and symptoms of asthma.
Aside from the irritants, asthma is also caused by allergens and infections.
Common allergens include pets, house dust, molds, polllen, feathers, and
foods like milk and eggs. Viral and bacterial respiratory infections can
also trigger an asthma attack.
Symptoms include cough, wheezing, chest tightness, and shortness of breath.
The severity of the symptoms is the basis of treatment. It is therefore
important to monitor an individual with an asthma attack to determine
whether he or she is improving or is getting worse. The manner of speaking
and breathing is closely monitored together with the skin color, level of
awareness, and the presence or absence of chest indrawing.
Increased physical activity such as running, weather changes, and other
activities that involve deep rapid breathing can trigger an asthma attack.
Avoiding the triggers help prevent occurrence of an attack.
Asthma is managed using inhalation and systemic bronchodilators and
anti-inflammatory drugs. Please visit your physician to determine the best
medication suited for you.
