Allergic Asthma is a condition where inflammation of the airways (in patients suffering from Asthma) is caused by the immune system’s overreaction to certain allergic reactions.
Causes, incidence, and risk factors
Asthma is caused by inflammation in the airways. The muscles surrounding the airways restrict, limiting the amount of air that can pass through, causing a wheezing sound.
Asthma symptoms and attacks can be triggered in patients with sensitivities to certain allergens and allergy-causing substances.
Depending on severity, an Asthma attack can last minutes to days and will become dangerous if airflow is seriously restricted.
Patients who suffer from asthma can have a history (individually or genetically) of allergens, including hay fever or eczema. Other patients may have no history at all.
Some common Allergic Asthma triggers could include:
- Chemicals in food or the air
- Pet hair or dander
- Cigarette smoke
- Respiratory infections
- Coughing with a possible presence of sputum (otherwise known as phlegm)
- Intercostal retractions
- Shortness of breath which increases during physical activity
