Risk factors for allergy can be placed in two general categories, namely host and environmental factors. Host factors include heredity, sex, race, and age, with heredity being by far the most significant. However, there have been recent increases in the incidence of allergic disorders that cannot be explained by genetic factors alone. Four major environmental candidates are alterations in exposure to infectious diseases during early childhood, environmental pollution, allergen levels, and dietary changes. Allergic diseases are strongly familial: identical twins are likely to have the same allergic diseases about 70% of the time the same allergy occurs about 40% of the time in non-identical twins. Allergic parents are more likely to have allergic children, and their allergies are likely to be more severe than those from non-allergic parents. Some allergies, however, are not consistent along genealogies parents who are allergic to peanuts may have children who are allergic to ragweed. It seems that the likelihood of developing allergies is inherited and related to an irregularity in the immune system, but the specific allergen is not. The risk of allergic sensitization and the development of allergies varies with age, with young children most at risk. Several studies have shown that IgE levels are highest in childhood and fall rapidly between the ages of 10 and 30 years.The peak prevalence of hay fever is highest in children and young adults and the incidence of asthma is highest in children under 10. Overall, boys have a higher risk of developing allergy than girls, although for some diseases, namely asthma in young adults, females are more likely to be affected. Sex differences tend to decrease in adulthood. Ethnicity may play a role in some allergies, however racial factors have been difficult to separate from environmental influences and changes due to migration. Interestingly, it has been suggested that different genetic loci are responsible for asthma, specifically, in people of Caucasian, Hispanic, Asian, and African origins.

Allergy is a disorder of the immune system often also referred to as atopy. Allergic reactions occur to normally harmless environmental substances known as allergens these reactions are acquired, predictable and rapid. Strictly, allergy is one of four forms of hypersensitivity and is called type I or immediate hypersensitivity. It is characterized by excessive activation of certain white blood cells called mast cells and basophils by a type of antibody known as IgE, resulting in an extreme inflammatory response. Common allergic reactions include eczema, hives, hay fever, asthma, food allergies, and reactions to the venom of stinging insects such as wasps and bees. 1 Mild allergies like hay fever are highly prevalent in the human population and cause symptoms such as allergic conjunctivitis, itchiness, and runny nose. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening anaphylactic reactions and potentially death. A variety of tests now exist to diagnose allergic conditions these include testing the skin for responses to known allergens or analyzing the blood for the presence and levels of allergen-specific IgE. Treatments for allergies include allergen avoidance, use of anti-histamines, steroids or other oral medications, immunotherapy to desensitize the response to allergen, and targeted therapy Classification and history: The concept of allergy was originally introduced in 1906 by the Viennese pediatrician Clemens von Pirquet, after he noted that some of his patients were hypersensitive to normally innocuous entities such as dust, pollen, or certain foods. Pirquet called this phenomenon allergy from the Greek words allos meaning other and ergon meaning work . Historically, all forms of hypersensitivity were classified as allergies, and all were thought to be caused by an improper activation of the immune system. Later, it became clear that several different disease mechanisms were implicated, with the common link to a disordered activation of the immune system. In 1963, a new classification scheme was designed by Philip Gell and Robin Coombs that described four types of hypersensitivity reactions, known as Type I to Type IV hypersensitivity. With this new classification, the word allergy was restricted to only type I hypersensitivities also called immediate hypersensitivity , which are characterized as rapidly developing reactions. Signs And Syptoms: Many allergens such as dust or pollen are airborne particles. In these cases, symptoms arise in areas in contact with air, such as eyes, nose and lungs. For instance, allergic rhinitis, also known as hay fever, causes irritation of the nose, sneezing, and itching and redness of the eyes. Inhaled allergens can also lead to asthmatic symptoms, caused by narrowing of the airways bronchoconstriction and increased production of mucus in the lungs, shortness of breath dyspnea , coughing and wheezing. Aside from these ambient allergens, allergic reactions can result from foods, insect stings, and reactions to medications like aspirin and antibiotics such as penicillin. Symptoms of food allergy include abdominal pain, bloating, vomiting, diarrhea, itchy skin, and swelling of the skin during hives. Food allergies rarely cause respiratory asthmatic reactions, or rhinitis. Insect stings, antibiotics, and certain medicines produce a systemic allergic response that is also called anaphylaxis multiple organ systems can be affected, including the digestive system, the respiratory system, and the circulatory system. Depending of the rate of severity, it can cause cutaneous reactions, bronchoconstriction, edema, hypotension, coma, and even death. This type of reaction can be triggered suddenly, or the onset can be delayed. The severity of this type of allergic response often requires injections of epinephrine, sometimes through a device known as the EpiPen auto-injector. The nature of anaphylaxis is such that the reaction can seem to be subsiding, but may recur throughout a prolonged period of time. Substances that come into contact with the skin, such as latex, are also common causes of allergic reactions, known as contact dermatitis or eczema. Skin allergies frequently cause rashes, or swelling and inflammation within the skin, in what is known as a wheal and flare reaction characteristic of hives and angioedema. A major breakthrough in understanding the mechanisms of allergy was the discovery of the antibody class labeled immunoglobulin E IgE - Kimishige Ishizaka and co-workers were the first to isolate and describe IgE in the 1960s

One gets allergy when body overreacts to things that don t cause problems for most people.these things are called allergens. Your body s overreaction to the allergens is what causes symptoms see the box below for a list of symptoms . For example, sometimes the term hay fever is used to describe your body s allergic reaction to seasonal allergens in the air, such as grass or pollen. Doctor may want to do an allergy skin test to help determine exactly what is causing your allergy. An allergy skin test puts tiny amounts of allergens onto your skin to see which ones you react to. Once you know which allergens you are allergic to, you and your doctor can decide the best treatment. Your doctor may also decide to do a blood test, such as the radioallergosorbent test called RAST . Pollen from trees, grass and weeds can cause allergies. Allergies that occur in the spring late April and May are often due to tree pollen. Allergies that occur in the summer late May to mid-July are often due to grass and weed pollen. Allergies that occur in the fall late August to the first frost are often due to ragweed. Mold is common where water tends to collect, such as shower curtains, window moldings and damp basements. It can also be found in rotting logs, hay, mulches, commercial peat moss, compost piles and leaf litter. This allergy is usually worse during humid and rainy weather. Animal dander- Proteins found in the skin, saliva, and urine of furry pets such as cats and dogs are allergens. You can be exposed to dander when handling an animal or from house dust that contains dander. Many allergens, including dust mites, are in dust. Dust mites are tiny living creatures found in bedding, mattresses, carpeting and upholstered furniture. They live on dead skin cells and other things found in house dust. Allergy is most frequently hereditary. A hereditary allergy is termed as atopy. In individuals with such family history, an allergic disease is manifested after a certain period necessary for the development of hypersensitivity to a given external factor. This process is called sensitization and is characterized by creation of antibodies in the body of the allergic individual that work against a given external factor allergen . Allergy, i.e. the so-called atopic constitution see the previous question , is hereditary. Congenital allergy, i.e. atopy, does not necessarily mean that the patient shall develop an allergy disease. Appearance of the disease in atopic person usually depends on the effect of the environment, e.g. long exposure to certain allergen, infection, etc. Appearance of an atopic disease is higher if both parents of the patient are atopic. Vitamin C: Recent studies have suggested that Vitamin C is effective in treating allergies, as it lowers histamine levels in the bloodstream. Hence, eating plenty of citrus fruits and juices, berries, broccoli, dark greens, onions, berries, and mangoes could prevent on-set of allergies. However, people who have an allergic reaction to certain fresh fruits may have to be more careful. Butterbur Petasites hybridus : Various studies conducted in Switzerland which were peer-reviewed by medical journals have revealed the supplements derived from Butterbur, reduces symptoms of allergic rhinitis hay fever in most patients. Hardly any side effects have been reported. Acupuncture: This involves placing needles onto specific points in the skin. The procedure relieves symptoms of hay fever. Quercetin: The supplements of this antioxidant are found in plenty in yellow onions. Studies have revealed that this supplement blocks allergy causing substances. It can be used alone or in combination with allergy medications. Chinese Skullcap: This is a herb with high level of antioxidants. It has anti-inflammatory and anti-histamine properties. Along with use of Chinese Skullcap, a Chinese herbal formula, bimminne , helps in treating hay fever. However, it should be noted that few natural substances may even inhibit histamine release. Although this may appear to be good for patients suffering from allergies, lowering histamine release completely may also prove dangerous. At times, these supplements, when taken along with prescription medication that inhibits histamines, the combo could cause trouble. Hence, to be on the safer side, it is best to openly discuss with the doctor all that you are taking for allergies. Ayurvedic treatments will be able to assist with the typical symptoms like sneezing, congestion, and coughing. Numerous naturopathic practitioners conceive that allergies are the main cause of the bulk of respiratory effects. Allergic responses are a result of many things, food, animals, environmental contributors and more. It is challenging to get rid of the symptoms unless the sufferer s psychological composition is also noted. Thankfully, Ayurvedic practitioners are able to do this. Specialists can place and actually address the cause of numerous respiratory problems within each individual that feels condemned by their allergic reactions. In Ayurveda education, it expresses that every person has his or her own unique anatomical structure that is made up of special mental, physical, and emotional aspects in addition to other types of components, which are named doshas. Providing a person sustains their doshas, everything is fine. Nonetheless, if this is not the case, then happiness and wellness may be compromised. This is often shown as an disease or sickness. According to the teachings of Ayurveda, allergic reactions are a result of disease. If are are no longer balanced, your body is responding to environmental forces including dust, pollen, food, chemicals, and animals. Simply put, if an individual ingests an unhealthy nutritional diet, the doshas could in theory, grow distressed. As a result, a negative result may go on when the individual is exposed to any allergens. Ayurvedic specialists are taught to find out which doshas are not adjusted. They also determine which environmental elements play a role in the reactions. Deflecting allergies appears simple if the affected individual just avoids all of the previously noted substances, animals, foods, etcetera.. However, advanced medication generally treats the symptoms instead of the origins of the issue. For those suffering from allergies, this is one of the numerous reasons why Ayurvedic treatment is worth looking into. If you do not reside near any Ayurvedic health spas, there are a few things that may help to alleviate your allergies. Neti pots, for instance, are sometimes employed to relieve allergy symptoms. Ayurvedic nasal therapies are also very helpful. Pranayama, a type of respiration method, can be used in concurrence with meditation to help cut down the symptoms. Like many other parts of our lives affected, diet is one of the most important things allergy sufferers can do to help themselves. Since damaging foods and substances send doshas out of balance, poor eating habits can make all of the difference

It seems that the likelihood of developing allergies is inborn and connected to an irregularity in the immune system. In the contemporary health researches several experiments have been done to reveal the causes of allergy. Allergic diseases are more common in industrialised countries than in countries that are more traditional or agricultural, and there is a higher rate of allergic disease in Indian urban populations versus rural populations, although these differences are becoming less defined. Longitudinal studies in the third world state an increase in immunological disorders, as a country grows more affluent and, presumably even cleaner. The use of antibacterial cleaning products has also been associated with higher degree of asthma in India. Treatments of allergy however largely depend on the cause of allergy.

Allergies are common cause now a day. It is mostly comes from non veg. It is better to avoid meat. And if you have allergies you start applying the paste of neem leaves and mehndi leaves and boil it with mustard oil and apply it wherever you have allergies . Or Coconut oil and kapur mix it and apply. The allergies will automatically go. But as far as internal allergies are concerned you have to avoid non veg and take neem leaves.
