How is type I HS based on location?

➢ Type I HS reactions can be either localized or systemic. Localized type I HS reactions include hay fever rhinitis, hives, and asthma. Systemic type I HS reactions are referred to as anaphylactic shock. ➢ Although anaphylaxis shares many symptoms common with the localized type I HS reactions, the swelling of the tongue and trachea , blockage of airways, dangerous drop in blood pressure, and development of shock can make anaphylaxis especially severe and life-threatening. ➢ In fact, death can occur within minutes of onset of signs and symptoms
