Allergy to Insect Stings

There are several stinging insects found within the US which include honeybees, hornets, wasps, yellow jackets and fire ants. Only some people are allergic to insect venom, but skin reactions will usually occur as a result of an insect sting.

Currently more than 2 million Americans are allergic to insect stings, though the degree of the allergy varies. Many of these can have severe allergic reactions. When someone is allergic to insect stings then subsequent stings will usually be either similar or worse in nature to the previous sting.

Types of Insect Sting Reaction

Most insect sting reactions will be non allergic, which results in local pain, itching and swelling. The treatment usually involves disinfecting the local area and keeping it clean. There can be increased swelling alongside nausea and vomiting. This only occurs in around 10% of cases and is not due to an allergic reaction.

Allergic reactions occur in those who have developed antibodies against the venom after being stung in the past. The reaction of any subsequent sting will vary between people. Symptoms usually include: itching, hives, skin flushing, itching or tingling inside the mouth and nausea or vomiting.

The most serious type of allergic reaction is known as anaphylaxis which can even lead to death. This is due to difficulties in breathing, swelling of the tongue, dizziness and fainting. Any symptoms of allergy may occur almost immediately, but it is possible for them to be delayed for as long as 24 hours.

It is important that emergency treatment is sought in the case of any anaphylactic reaction, whether this is caused by an insect sting or any other allergen. In the case of less severe allergic reactions prompt treatment is usually required.
