Understanding allergies symptoms

Allergies occur when the immune system overreacts to substances like pollen, dust, pet dander, or certain foods, mistaking them for harmful invaders. This reaction triggers symptoms such as sneezing, itching, swelling, and breathing difficulties. Allergies can range from mild to severe, with some cases leading to life-threatening anaphylaxis. Common treatments include antihistamines, decongestants, and avoiding allergens.
