Peanut allergy is one of the most dangerous allergies, but what causes this allergy? It is thought to cause up to 80% of allergic reactions that kill or come close to killing people every year. Only in the United States do 1. 5 million people have an allergy to peanuts, and that number is growing, just like it is in other First World countries. The exact cause of the allergy is unknown, but everyone knows what happens in the body to cause an allergic reaction. No matter what causes it, a peanut allergy can kill the person who has it. 
People should be respectful of those who say they are allergic to peanuts and try to be careful around them. Sometimes, even being touched by someone who has handled peanuts can cause a reaction. A peanut allergy is an abnormal response from the immune system, just like any other allergy. The body decides that the proteins in peanuts are immunologically dangerous, so it makes an antibody called Immunoglobulin E (IgE) to fight peanuts the next time they enter the body. Sometimes you have to eat peanuts more than once to get IgE. When a person with this type of allergy eats peanuts, it causes the body to make histamines to fight the peanuts, which causes an allergic reaction. When you eat peanuts if you have a mild peanut allergy, which is sometimes called an intolerance, you might have stomach pain and heartburn. If a person has a severe allergy, they may get hives, rashes, trouble breathing, a fast heart rate, and, in the worst case, anaphylaxis, which is a state of unconsciousness that can quickly lead to coma. 
To stop the immune system from reacting, epinephrine must be given to the patient right away. This is why many people with serious allergies carry allergy kits. Studies have shown that kids are more likely than adults to become allergic to peanuts. If a child doesn't eat peanuts before he or she is four, it's very likely that he or she won't become allergic to them. Some children who were once allergic to peanuts have grown out of it, but this is something a doctor should decide. A big risk factor is having a parent who is allergic to peanuts. Children of parents who are allergic to peanuts are often allergic to peanuts as well. If someone thinks they might be allergic to peanuts, they can get allergy testing to make sure. Patients can get skin tests, in which proteins are put directly under the skin and cause a rash if they are allergic. IgE can also be looked for in the blood with a blood test. 
Doctors think that humans may be changing their immune systems by getting rid of diseases and keeping their environments too clean. This is because more and more people in First World countries are allergic to peanuts. When there aren't any dangers in the immune system's natural environment, it may do strange things, like react badly to common foods. Also, the fact that peanut products are used a lot in food may be making the problem worse. Peanut products are almost everywhere, making it hard to keep young children away from them. They are in oils, most processed foods, skin care products, and even some plastics.

Any food allergy can be scary, but serious peanut allergies appear to be extremely deadly for a number of reasons. Peanuts and products made from peanuts are very popular, which makes it nearly impossible to get rid of all peanut protein from a certain area. People with the worst kind of allergy can have a reaction just by touching a phone or doorknob that has even a tiny bit of peanut residue on it. A violent allergic reaction can also be caused by peanut dust in the air. One reason why peanut allergies are dangerous is that they only need a very small amount of peanut protein to cause a reaction. Some people with peanut allergies are not as sensitive as others, but those who can go into anaphylactic shock very quickly when they eat peanut products. They can also get hives, which are painful rashes that are caused by allergens. Anaphylactic shock or anaphylaxis is a serious allergic reaction that can cause the tissues around the upper airway to swell. This makes it hard to breathe normally, which can be life-threatening. Because there is no treatment available for peanut allergies, people who have them are always at risk of having a severe allergic reaction or going into anaphylaxis. A normal day at work or school can be very hard if you are allergic to peanuts. This is because many products and materials contain small amounts of peanuts or may have come in contact with peanut products by accident. 
A person with severe peanut allergies may be careful not to eat anything with peanuts in it, but they may still come into contact with peanuts from other sources. If no one is around to help, the person could have an allergic reaction that could kill them. Only a very small number of people have the worst kind of peanut allergy, but some people may have a sensitivity that hasn't been diagnosed but causes many of the same problems when exposed. If you use an auto-injection pen with epinephrine, the allergy symptoms might go away right away, but a person with a severe allergy might have another round of symptoms a few hours later. Due to the risk of a serious allergic reaction, peanuts are not allowed in many public places and travel industries. Since peanut allergies are most likely to happen in young children, some public schools no longer serve peanut butter sandwiches or other foods with peanuts. Many airlines have also stopped serving peanut products as snacks on flights, mostly because a passenger with a severe allergy to peanuts could have a medical emergency while the plane is in the air. Foods that have peanuts or tree nuts in them must have a warning label.
