Hypersensitivity to common substances, such as dust, pollen, or certain foods, occurs when the immune system overreacts to these substances, triggering an allergic reaction. Symptoms can range from mild to severe, including sneezing, itching, hives, or even anaphylaxis in extreme cases. Managing hypersensitivity typically involves avoiding the trigger and may include medications or allergy shots.
