Allergy and Immunology 49 years experience
Yes.: Anaphylaxis is often an extreme allergic reaction, but may not always be readily attributable to an allergy. Some people, for example, may experience anaphylaxis from exercise under certain circumstances. Most episodes of anaphylaxis may be linked to allergic sensitization as in the case of insect sting reactions, certain drugs, foods, and in some individuals with severe inhalant allergies.
Dr. Michael H. T. Sia
Pediatrics 31 years experience
Not all.: "anaphylaxis "(extreme response to food/drug allergy) is a serious, potentially life threatening response notable for swelling, hives, low bp, dilated blood vessels. The immune system creates a disease fighting antibiody (ige) toward a harmless substance (like food). "allergies" cause sneezing, coughing, wheezing & itching. Some allergies can be severe & possibly fatal-anaphylaxis.
