Why Do People Have Allergies?

Almost everyone has an allergy, whether or not they are massive, like peanut allergies, or minor, like seasonal allergies. The first time I had allergy was in my Ninth grade year of High School. When Miss. Town son's writing class came along and acted like a cup of milk in my existence.

The ironic thing about allergens is that most aren’t harmful to the body, but this doesn’t stop the immune system for mistaking them for foreign bodies, which is why it decides to fight back. Our immune systems are amazing things. They create proteins to fight disease, which are known as antibodies. These antibodies try to battle it out against the antigens. Once our immune system creates certain antibodies, they’ll recognize the same intruders again and protect our bodies automatically year in year

The most common causes of anaphylaxis include medications, food insect’s stings. In adults, the main causes are medication, medication like penicillin and its derivatives, followed in frequency by aspirin and anti-inflammatory. The second largest category are food, among which fruits, nuts and seafood are the most frequents trigger. In children, the most common triggers are foods like eggs, milk, nuts and seafood.

“The immune system didn’t evolve for allergy. Why in a hundred billion years of evolution would we evolve a response for allergy?”(Joel Weinstock). Throughout the years, food allergies have been on a dramatic increase in the United States. Allergic reactions are caused by antibodies in the immune system which are also known as immunoglobulins. There are five types of immunoglobulins that are produced to fight antigens, such as, bacteria, toxins, viruses, animal dander, fungus, and cancer cells . Each immunoglobulin fights a different antigen and is found in different parts of the human body. Immunoglobulins help the immune system when an allergen has entered the human body, each of these antibody releases a chemical called histamine, which is produced by the immune system to protect the human body. Histamine is one of the main reasons why allergy symptoms are triggered. Food allergens can cause severe or mild reactions due to an unusual mistake the immune system can make. The immune system usually mistakens a particular substance to be physically harming the human body and in the act to try and protect itself, it releases histamine. There are many reasons why food allergies occur, such as processed foods, genetically engineered proteins in foods, pesticides, and genetically modified organisms can all cause serious food allergies. It all began in 1996 when Genetically Modified Organisms were introduced to our foods. Genetically Modified Organisms are organisms that have been

There are three main players in the development of allergies: immunoglobulin E (IgE), mast cells and histamine. IgE is a specific type of antibody that has a significant role in the development of allergies; IgE is able to bind to both allergens and to mast cells, cells that mediate inflammatory responses such as hypersensitivity and allergic reactions (3). Once IgE binds to an allergen, the allergen releases T cells to stimulate B cells, developing into plasma cells that produce and release more antibodies (4). Once

An allergy is a hypersensitivity reaction by the immune system that occurs to certain antigens for which the body perceives as a threat and has an overreaction to. Patients generally experience inflammation of the airways, among other symptoms caused by the

Currently, I am studying the psychosocial burden of food allergies on humans. This burden can cause severe stress and anxiety. Before I started that topic, I needed to learn about the main problem food allergies. Essentially, An allergy is an overemphasized reaction by the immune system in response to exposure to certain foreign substances. It is exaggerated because these exotic substances are usually seen by the body as harmless and no response occurs in nonallergic people. In allergic individuals, the body recognizes the foreign substance and the immune system generates a response.

Allergies may happen from anything your body is sensitive to. This may be food, medicines, pollens, chemicals, and nearly anything around you in everyday life that produces allergens. An allergen is anything that causes an allergy producing substance. Heredity is often a factor in causing these problems. This means you may have some of the same allergies as your parents.

Food allergy is a potentially severe immune response to a food or food additive. Food allergy and asthma frequently co-exist. Since asthma may predispose a patient to suffer a life-threatening reaction to a food, aggressive asthma management is essential. Although food allergy is rarely the etiology of asthma, it is important to monitor food allergic patients because they have a higher risk of developing asthma later in life and these patients may have more severe asthma. Although the ingestion of food allergens rarely leads to only respiratory reactions, cough and wheeze can be seen with food allergen inhalation. More research is needed to determine if certain modifications to the maternal and infant diet may modify atopic outcomes, including

Take allergy symptoms seriously on their onset as it may not just be a simple allergy, it is best to consult your doctor to identify what causes your allergies and if you are required

It is reported that some people characterize allergies as an immunity, “gone wrong” because they do not have the protective antibodies a normal person would carry if exposed to an allergen. The best way to overcome histamine is to avoid complete contact with the allergen (6). There is no official cure for histamine. However, people take medications to block the action of histamine, known as antihistamines. They control or inhibit allergy symptoms caused by foreign pathogens. Allergic reactions are reduced or stopped when antihistamine bind to the histamine receptors, therefore preventing histamine from connecting with those receptors (2). The history of antihistamines dates back to the 1930s when a notable researcher and professor studied drug

For adults , medication is the first cause of allergy for example: penicillin, aspirin, ibuprofen

Allergies are a number of different conditions caused by hypersensitivity of the immune system from something in the environment the causes some problems in some people. Some allergists, a medical practitioner specializing in the diagnosis and treatment of allergies, say that there are ways to prevent children from developing allergies and that there are a ton of ways to do so.

People with allergies are also at a high risk for getting asthma, or enduring a asthma attack. Not all people with allergies develop asthma though. Allergies are caused by their immune systems actually attacking their own body. Basically, one's body is confused and thinks that a body cell is actually a foreign cell, virus, bacteria, in the body that it must attack. So the immune systems response is to engulf the "invading" cells. The reaction causes an allergic reaction. Some of these allergic reactions become systemic, which simply means that ones entire body becomes affected by this mix up in the body. Swelling, itching, and many other symptoms are responses to such a reaction. In some allergic responses, inflammation of the bronchial can occur, which causes a difficulty in breathing, which is an asthma attack. Some factors the trigger an allergic reaction which can result in a asthmatic response are; tobacco smoke, dust mites, cockroaches, and animal dander.

Allergies are among the most common inveterate case worldwide. Allergy symptoms range from making you powerless to putting you at risk for life-menacing reaction.Food allergies are defined as “ the body 's abnormal responses to harmless foods; the reactions are caused by the immune system 'sreaction to some food proteins” (thefreedictionary.difntion.com).In other words,The job of the body’s immune system is to identify and ruin germs (such as bacteria or viruses) that make you sick. A food allergy results when the immune system wrong targets a harmless food protein an allergen as menace and attacks it.
