Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to something in the environment that usually causes little problem in most people. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, runny nose, shortness of breath, or swelling.Food intolerances and food poisoning are separate conditions.
Common allergens include pollen and food. Metals and other substances may also cause problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine. Diagnosis is typically based on a person's medical history. Further testing of the skin or blood may be useful in certain cases. Positive tests, however, may not mean there is a significant allergy to the substance in question.
Allergy is a peer-reviewed medical journal covering the field of allergy and immunology, that is published by John Wiley & Sons on behalf of the European Academy of Allergology and Clinical Immunology. It is indexed in PubMed and publishes both original articles and reviews. The current editors-in-chief are Thomas Bieber and Hans-Uwe Simon.
Every day I wanna stay in bed
'Cause my life is such a mess
Can't be bothered to get dressed
So sick of my ugliness
Constant cough and chronic wheeze
Twenty-first century disease
I just can't get no relief
Allergy
I got I got I got an allergy
I got an allergy to my life
Got no future, got no past
Try to cover up the cracks
Everything is such a drag
Ragged days all faded black
Doctor says i'm highly strung
Sells me drugs for choking lungs
Got to stay inside the slum
