“过敏”是怎么回事？

what is allergy？

过敏是免疫系统对一种物质的过度(超敏）反应，而这种物质通常对大多数人无害。（过敏不是免疫力低，而是免疫失衡）An allergy is an overreaction （hypersensitivity）of the immune system to a substance that is normally harmless to most people.

这些物质（诱发了过敏）就被称为过敏原，包括花粉、宠物皮屑、尘螨、霉菌、昆虫毒液、某些食物和某些药物。These substances are known as allergens and can include things like pollen, pet dander, dust mites, mold, insect venom, certain foods, and certain medications.

对某种物质过敏的人体内存在特异性抗体，再接触过敏就会发病。People who are allergic to certain substances have specific antibodies in their bodies, and exposure to allergies can lead to symptoms

这些抗体触发化学物质的释放，如组胺等，从而引起过敏症状。These antibodies trigger the release of chemicals, such as histamine, which cause allergy symptoms.

过敏症状，可能因过敏原而异、因人而异，但常见的症状包括打喷嚏、流鼻涕、眼睛痒、皮疹、胃痉挛和腹泻。Allergy symptoms can vary depending on the allergen and the person, but common symptoms include sneezing, runny nose, itchy eyes, skin rash, stomach cramps, and diarrhea.

严重过敏反应，可危及生命，呼吸困难和血压迅速下降休克。In severe cases, an allergic reaction can also cause anaphylaxis, a life-threatening reaction that can cause breathing difficulties and a rapid drop in blood pressure.

如果疑似过敏，可以去变态反应科，也叫过敏科就诊，得到正确的诊断和治疗。If you think you may have an allergy, it‘s important to see an allergist for a proper diagnosis and treatment plan.

过敏的治疗方法包括避免过敏原，服用药物缓解及控制症状，及脱敏疗法，这是一种治疗方法，可以帮助你随着时间的推移降低对过敏原的敏感性。 Treatment options for allergies can include avoiding the allergen, taking medications to relieve symptoms, or receiving allergen immunotherapy, a type of treatment that can help reduce your sensitivity to allergens over time.
