Why is a second bee sting more dangerous than the first for a person who is allergic to bee stings?
489774
If someone is allergic to bee stings and has never been stung before, then they really are not allergic yet.  They need to be exposed to the allergen first.  \n\nThe first sting "sensitizes" their body towards beestings.  The second sting can cause a full-blown allergic reaction.\n\nYou can still have an allergic reaction from the first sting... however it would be a far less serious reaction than the second sting.

It isn't really possible to have a true allergy to those things because they are just hormones...your body already has these hormones.  What sounds like might be happening is when you have an increased level of hormones (when you took depo, bc pills and had your baby) your body reacted to it by getting hives.  I might go see an endocrinologist, which is a doctor that specializes in hormones.  You could go see an allergist too.

Avoid whatever it is that you are allergic to.  Then you won't get the hives and you won't need a cure.  I am extremely sensitive myself, and yes, sometimes, I don't know what set off the reaction, but I have a good idea of the things I need to avoid.  Avoid any lotions or soaps with perfumes or artificial colors.

Yes. It will only relieve it, but not permanently, and it depends on the allergy causing the hives.  My wife has allergies to shrimp, and she has taken BENADRYL only a couple of times and these times it has given her some relief.  Allergists will tell you that your body will react differently to the same allergy depending on the strength of the way the item is touched or smelled or consumed.  Don't depend on the BENADRYL to save anything. It is just relief.

Sounds much like an allergic reation .. and yes you can be allergic to it .. in fact humans can be allergic to almost anything.

Well actually only some bees can sting people, and only sometimes do stinging bees die after they sting, contrary to popular belief. \n\nThere are many species of stingless bees. All the bees native to Central America are stingless. Fourteen of the 1600 Australian native bee species are stingless.\n\nThe stinger is a modified oviposter, or organ for laying eggs. Therefore, the male or drone bees are stingless. There are species of solitary bees where every female is fertile, that are also stingless bees. \n\nThe stinger was evolved for bee to bee combat, and only when bees sting mammals do the barbs in the bee get caught in the animal, and this causes some of the internal organs to be pulled out of the bee after stinging. Bees that sting other things besides mammals usually do not die. \n\nA close relative to bees, the social wasps, always have "unbarbed" stingers and can sting as often as they like (there are other wasps, like parasitic wasps, that have no stinger). Hornets, a term for some large wasp species, have unbarbed stingers, as do yellow jackets, which are small wasp species (actually, according to 7. they are not really unbarbed, but the barbs are short enough that the stinger can be pulled out without killing the insect). \n\nThere are even some bees that have unbarbed stingers, so they do not die after stinging people, and can sting repeatedly (see references 3, 5, 6). The queen bee usually has a barbless stinger so it also can sting repeatedly without dying.

Absolutely not!  \n\nIf people who have allergies and sneeze numerous times in a row (my friend can sneeze more than 10 times in a row during allergy season) suffered a stopped heart, they'd die by the time the sneezing fit was over.

Several members of my family can have anaphylactic reactions to certain foods and medications containing corn.  I have driven myself to the doctors with my throat swelling.  My mother has landed in the emergency room more than once. All three of my kids have the potential, but avoidance is the key.  We do carry an Epipen.

yes, it CAN trigger an attack..definetly talk to an allergy specialist before you take the first dose-and then the second dose of your medication.  remember your body never rejects something in its first exposure, but it can reject it in any of the following exposures.  so if you've tried it once and it contains a trace of something you're aware you're allergic to, it does NOT mean that you are safe to take it every time.  i am sure in today's market for pharmaceuticals and vitamins that there will be alternatives your allergy specialist can recommend you take.  good luck and hope you feel better

miapia87 is incorrect...bees dont eat other insects...they consume nectar...the sting that they have is for defense...and when they sting...the whole stinger and part of the abdomen will come off...that is why bees die after they've stung something...bees usually need to defend the nest from other queen bees who try to overthrow the dominant queen...and also from wasps and hornets...these insects do eat other bugs...anyway wasps and hornets don't die once they've sting you...they are more vicious than bees...their venoms are more potent...and...they can sting you again and again...so please avoid them...at all cost!!!

Scientists believe that IgE was originally made by the body to fight threats to the body such as worms. As these are much less common in today’s world, IgE is mostly made in response to allergens, such as pollen or cat dander, which do not pose much of a threat to the body. However, scientists find that when high levels of IgE antibodies are present, the body releases histamine which can makes allergy symptoms worse, and creates inflammations that can trigger asthma.\n\nIt is not known why some people produce IgE when exposed to substances such as pollens even though they pose no threat to the body. It is also not yet know why one person will produce more IgE than another person with the same allergies and same exposure.

You might be sensitive to some ingredient.\nI've seen people get hives, turn red and splotchy around the eyes, break into a sweat and get weak, etc after drinking even small amounts. These same people will have no adverse effects with a different drink on a different night.

Well, Anaplylactic Shock is when your airway swells shut as an allergic reaction to something (for example, if I am injected with ionized contrast dye like a CAT scan or an IVP, my throat will swell shut and I can't breathe).  Some people have this reaction to bee stings.  People with this type of severe allergy usually carry on them something called an Epi-Pen.\n\n(I also wear a Medic Alert bracelet so if I'm knocked out, paramedics will know NO CAT-scans)

An allergic reaction occurs due to a sensitivity to an allergen such as bees, vaccines, foods. If someone is allergic to say bees - they have generally been bitten before and their body has responded by producing antibodies. The next time they get bitten their bodies produce more of this antibody which attaches itself to the antibodies already present.  This then causes the body to release histamine etc to conteract the increase in antibodies.  As a result the person experiences things such as vasodilation (the blood vessels dilate), increased smooth muscle contraction in the lungs (makes it harder to breath) and increased mucous secretion.  In more serious cases this leads to anaphylactic shock due to the vasodilation and fluid loss.

I use to raise honeybees many oldtimers swear that being stung by the bees on the affected area can aleveate pain and swelling from arthritis. Be careful if you have insect bite allergies!!
