Sometimes severe allergic reactions due to exposure to allergens (allergens) can cause very serious, dangerous and life-threatening conditions, which are called high-risk and critical conditions anaphylaxis.

Bee stings, especially a type of bee called Wasp, introduce a toxin into the body that causes severe immune system reactions. After a bee sting, a person’s immune system will make special antibodies to neutralize the venom of a bee sting. These antibodies are at high risk of severe anaphylactic reactions in the event of subsequent bites by bees.

How long does it take for anaphylaxis to occur after a bee sting?

When you get a bee sting, regional reactions occur in the first twenty-four to forty-eight hours and usually resolve within five to ten days. Delayed reactions following bee stings are rare; these uncommon delayed reactions occur during the following days and weeks.


A variety of reactions following the bite

There is redness and swelling and pain around the bite site

In this type of reaction, the swelling exceeds the point of the bite, for example, swelling in a person with a bee sting on his hand, his forearm swells within forty-eight hours, in most cases this type of reaction also occurs within five to ten days. It will be fixed later.


Symptoms of allergic reactions

Symptoms in mild reactions include:

Anaphylactic reactions are very severe and are accompanied by progressive dilation of blood vessels and if left untreated can lead to death within fifteen minutes. This type of reaction is uncommon, but lack of treatment or delay in starting treatment will be very dangerous. Symptoms of anaphylactic reaction following bee stings include the following:

If you experience any of the above symptoms, do not miss the opportunity to go to the emergency room.


How long does an anaphylactic reaction occur after a bee sting?

Shortness of breath, extensive urticaria, and swelling are the main symptoms of an anaphylactic reaction following a bee sting. A severe allergic reaction or anaphylaxis usually occurs two hours after you are bitten by a bee Occasionally, in a rare number of people who suffer from bee stings, this severe allergic reaction occurs within the first twenty-four hours after the bite. Fewer people experience a delayed reaction, which occurs days and weeks after the bite.

Without fast treatment, the symptoms of an anaphylactic reaction can quickly worsen and can cause death within minutes or hours.

Moderate allergic reactions following a bee sting do not include shortness of breath and hypotension, but redness and swelling appear around the bee sting, sometimes up to ten centimeters in diameter, which will often resolve within a few days.

Sometimes people have a biphasic reaction. It means after the normal reaction phase, they have a shutdown period of one to eight hours before the second phase of the reaction (secondary reaction), and this second phase can last for several days.

Death following an allergic reaction occurs within minutes and it is very rare for death to occur after a few days or weeks after an anaphylactic reaction.


The final words

You should know that most cases will not be necessary if you have a bee sting, but if you have a history of severe allergic reactions and anaphylaxis, or if you have any of the symptoms of an anaphylactic reaction such as urticaria, shortness of breath, increased heart rate, confusion, etc. immediate contact with the emergency services is required

In most cases, anaphylactic reactions improve within a few hours, but broader reactions often take longer to recover.

In many countries, which identify people with a history of allergies to bee stings, etc., they have been given epinephrine pens so that they do not waste time reaching the medical staff.
