7Insects
Some insects can cause allergic responses. Several biting species like ticks or mosquitoes can introduce anti-coagulants into your body, while stinging categories like ants, hornets, bees, and wasps can inject venom. Bee sting allergy is an especially dangerous form as it would trigger serious symptoms. These include inflammation and swelling around the area of the sting. In more severe cases, you would have an anaphylactic response in the whole body, which causes reduced blood pressure, increased pulse rate, difficulty swallowing and breathing, wheezing, and swollen airways.
