Allergy (Allergy and Asthma)

When a person is very sensitive to certain foods, liquids, pollen, or animals. The allergy can make the person ill, including sneezing, itching, and rashes. Severe allergies can even be fatal (cause death). Some organisms which cause uncomfortable allergies with people include Ragweed (pollen), Poison Ivy (oil), and Honey Bees (venom).

Allergy (Environmental Health)

An acquired, abnormal immune response to a substance that can cause a broad range of inflammatory reactions.

Allergy (Genetics and Food)

A hypersensitivity (characterised by a damaging immune response) to an allergen or substance in a person's environment such as dust, pollen, fur or a chemical. Can manifest as hayfever, skin rash, asthma, food allergies etc. Referred to as an allergic reaction.

Allergy (HIV and AIDs)

An immediate or delayed immune reaction caused by exposure to an antigen (allergen).

Allergy (Health)

Allergy (Health and Beauty)

An allergy is defined as a sensitivity to certain substances, such as pollen.

Allergy (Horse Health)

A hypersensitive state of the immune response, wherein exposure to a particular substance (an allergen) results in a noxious and sometimes physically harmful immunologic response.

Allergy (Immunization)

A condition in which the body has an exaggerated response to a substance (e.g. food or drug). Also known as hypersensitivity.

Allergy (Medical)

A negative reaction to a substance that in most people causes no reaction

Allergy (Medical Specialty)

The diagnosis and treatment of allergy-related diseases, including asthma, hay fever, hives, eczema, and drug and food reactions.

Allergy (Microbiology)

A hypersensitive condition acquired by exposure to a particular allergen (helminth infections; house dust mite or ectoparasite bites or stings).

Allergy (Mold)

Hypersensitivity of the body's immune system in response to exposure to specific substances (antigens).

Allergy (Nutrition)

Allergy (Science)

Abnormally strong reaction of the body's immune system to a foreign substance

Allergy (Veterinary)

Immunological hypersensitivity to certain foreign antigens.anemia - reduction of red blood cells or hemoglobin.
