Allergic reactions to insect stings

Allergic reactions to insect stings occur when the immune system overreacts to substances in the insect's venom, such as bees or wasps. For some, this immune response causes mild symptoms like redness, swelling, and itching. In more severe cases, it can trigger anaphylaxis, a rapid, life-threatening reaction involving difficulty breathing, swelling of the throat, and a drop in blood pressure. People with allergies to insect venom should carry emergency medication like epinephrine and seek prompt medical attention if stung. Repeated exposure may increase sensitivity, so it’s important to be cautious around insects if you have a known allergy.
