Excessive immune reactions, which are abnormal or inappropriate responses to common substances such as dust mites, pollens, certain foods, fur, and the like, are referred to as hypersensitive or allergic reactions. These appear in various patterns and form according to the area of outbreak (bronchial tubes, skin, mucous membranes of the eyes and nose). The allergy department treats and studies disorders related to hypersensitive reactions.

Allergic disorders and asthma are increasing global trends as lifestyles are modernized, and reported outbreaks of disorders like asthma, allergic rhinitis, atopic dermatitis have been on the increase in Korea. Worse yet, atopic disorders which used to be naturally cured with aging, have begun to emerge or turn chronic even into adulthood.

Allergic reactions can be alleviated with proper treatment and management based on precise diagnosis and a correct understanding of the disease. It is thus important to educate patients about avoidance, environment management, and prevention alongside the varied medical treatments. Even certain disorders which effectively respond to the immunotherapy can be fundamentally cured through these treatments.

The Haeundae Paik Hospital Allergy department handles a range of allergic disorders including asthma, respiratory disorders (allergic rhinitis, sensitive pneumonitis, eosinophilic lung disease), hives, angioedema, food allergies, medicine side effects (allergies) and anaphylactic shock. Chronic coughs, often caused by allergic diseases is the main concern of this department. The allergy department implements systematic and comprehensive diagnosis, treatment and prevention for a host of allergy disorders.
