When a person is allergic to a particular substance, such as a food or dust, the immune system mistakenly believes that this usually harmless substance is actually harmful to the body. In an attempt to protect the body, the immune system starts a chain reaction that prompts some of the body's cells to release histamine and other chemicals into the bloodstream. The histamine then acts on a person's eyes, nose, throat, lungs, skin, or gastrointestinal tract, causing allergy symptoms. You've probably heard of antihistamine medications - these help to fight symptoms caused by the release of histamine during an allergic reaction.</p> HistaminaLa histamina, una sustancia química presente en algunas células del organismo, provoca muchos de los síntomas de las alergias, como secreciones en la nariz o estornudos.https://kidshealth.org/ws/RadyChildrens/es/parents/histamine-esp.html/4499c4e9-c6a9-4212-8cae-1cfecfbef114kh:age-allAgesOrAgeAgnostickh:clinicalDesignation-allergykh:clinicalDesignation-pulmonologykh:genre-dictionarykh:primaryClinicalDesignation-allergyAsthma Words to Knowhttps://kidshealth.org/ws/RadyChildrens/en/parents/asthma-center/words-know/1e3f21a2-c4e3-4dc4-8aa6-850a19c47fff
