Asthma

• Asthma is a common, chronic inflammation of the airways to the lungs 
• In asthma, Inflammation leads to swelling and mucus production, resulting in reduced airflow and bronchospasm
• During an acute asthma attack, constriction of the bronchi smooth muscle may cause significant airflow obstruction
• Common symptoms of an asthma attack include shortness of breath, chest tightness, wheezing and coughing
• Environmental triggers of asthma include: allergens, smoke/scents, stress, food preservatives/chemicals, arthropods (dust mites), cold air, exercise
