A disorder characterized by inflamed airways and difficulty breathing.
A chronic inflammatory condition of the airways and one of the most prevalent chronic conditions in Canada. The airways of a person with asthma differ from someone without asthma because the airways of those with asthma become inflamed (swollen) and are extra-sensitive or twitchy (hyperresponsive). The inflammation and hyperresponsiveness cause airways to respond to a variety of triggers, such as pollen, dust, and pets. Many of the triggers also cause inflammation and increased production of mucus. For more information, click here.

Typical symptoms of asthma include wheezing, shortness of breath and coughing.
A respiratory condition characterised by difficulty in breathing, constriction in the chest and often coughing or gasping.

Asthma is a chronic, inflammatory lung disease characterized by recurrent breathing problems. People with asthma have acute episodes or when the air passages in their lungs get narrower, and breathing becomes more difficult. Sometimes episodes of asthma are triggered by allergens, although infection, exercise, cold air and other factors are also important triggers.
Respiratory condition marked by recurrent attacks of wheezing, coughing, shortness of breath, and labored breathing caused by narrowing of the airways.
A reversible condition of the lung that is characterized by airway inflammation, increased mucus secretion, and airway spasm, resulting in airflow obstruction.
Asthma is a chronic respiratory disease, often arising from allergies, that is characterized by sudden recurring attacks of labored breathing, chest constriction, and coughing (from American Heritage Dictionary). Asthma is a disease of the bronchial tubes, or airways of the lungs, characterized by tightening of these airways. Not every person with asthma has the same symptoms in the same way. It is a chronic condition; people with asthma live with it every day and for their whole lives. People with asthma have very sensitive airways that react to many different things in the environment called "triggers." Contact with these triggers cause asthma symptoms to start or worsen (from WebMD).

Allergic asthma is caused by an allergic stimulus; most common in children and adults; caused by exposure to substances such as dust mites, plants, pollens, and molds.

Condition marked by labored breathing and wheezing, sense of chest constriction, and often attacks or coughing or gasping. Often from an allergic origin.
A lung disorder. It is marked by attacks of breathing difficulty, wheezing, coughing, and thick mucus coming from the lungs. The episodes may be started by breathing foreign substances (allergens) or pollutants, infection, vigorous exercise, or emotional stress. Treatment includes getting rid of the cause if possible. Sprays or wideners of the bronchi taken by mouth, and steroid drugs are also used. Certain drugs must not be used by persons with asthma. For example, some of the drugs for treating circulatory disease (beta-adrenergic drugs), barbiturates, and narcotics.

a disorder characterised by inflamed airways and difficulty breathing
Disease characterized by severe airway constriction and plugging of the airways with mucus.
Asthma is a chronic disease that makes breathing difficult. If you have asthma, the inside of your airways react strongly to things you are allergic to (allergens) or find irritating (irritants), causing the airways to narrow so less air can flow through them to the lungs. Allergens provoke allergic asthma; irritants provoke non-allergic asthma.
A chronic disorder characterized by shortness of breath, wheezing, coughing and tightness of the chest.

An obstructive airway disorder common in young children that can be exacerbated by thepresence of specific allergens
Asthma is a chronic disease of the respiratory system in which the airway occasionally constricts, becomes inflamed, and is lined with excessive amounts of mucus, often in response to one or more triggers. These acute episodes may be triggered by such things as exposure to an environmental stimulant (or allergen), cold air, exercise or exertion, or emotional stress. In children, the most common triggers are viral illnesses such as those that cause the common cold.Zhao J, Takamura M, Yamaoka A, Odajima Y, Iikura Y.
