Basically the body detects something unknown in the body and calls on the defence systems to get rid of it, but since these are used to destroying bacteria or viruses, they fail against the substance causing the allergy, so the defence mechanisms go into overdrive and the more they try the more they fail. An antibody called immunoglobulin E overreacting to what it thinks are infections and causing excess histamine to be released which in turn can cause severe reactions possibly leading to anaphylaxis. https://youtu.be/zk_oUk0bwxs
