why do insect stings cause inflammation?

Question

whenever insects bite us that particular region becomes swollen and red.why does this actually happen????are chemicals released into our body by these insects which cause the inflammation?

Answer 1

In a mosquito's bite is an anticoagulant, that keeps your blood from clotting while it sips merrily away. As for bees and wasps it's a cocktail of poisons that can kill. Remember bees leave their stingers, while wasps can sting many times over just for their enjoyment. The same way with jellowjackets which are hornets, they have the ability to smile while hanging their stinger into an unsuspecting victim....J/K!!

Answer 2

Yes, the poison released into the skin causes the inflammation and our body responds by trying to cleanse the affected spot. Usually the swelling is minor but if it is severe then you could be allergic to the venom/poison from the insect.

Answer 3

insects like wasps and spiders and bedbugs deposit miniscule amounts of toxins and/or contaminants into our bloodstream with each bite. your body reacts by becoming inflamed in that area as a way of fighting the infection caused by the contaminant. much the same way as you will spike a high fever when your body is under attack by a virus like cold or flu.

Answer 4

It's just our immune response to the bite. The red and white cells rush to the affected area to begin fighting off the minor wound. What I want to understand is why they have to hurt so bad! :)

Answer 5

Bees sting as a defense, mosquitoes for food (blood) they all don't carry Malaria

Answer 6

Histamine's are released in response to an injury/toxin which cause inflammation.
