Allergies generally happen as a result of the overreaction of the immune system to some harmful material. You can get an allergy either from eating, swallowing or inhaling a substance that the immune system recognises as harmful, including pollen, medicine, dust, pet hairs, insect stings and mould spores.
How Allergy Happens
Scientific research links allergy to environmental and genetic factors. When a person allergic to an allergen is exposed to it, the body passes through a number of processes to generate the allergic reaction. At first, the body generates IgE (Immunoglobulin E), an antibody. It then joins antibodies to a type of blood cell, known as the mast cell. Allergens attach to the IgE and cause the mast cells to discharge some chemicals, including Histamine, into the blood. This chemical causes the signs of an allergic reaction.
The different types of allergic reactions include IGE mediated, which has an immediate reaction time, and a non-IGE mediated, which has slower, more delayed reaction time. The result depends upon the immune response, which can be severe or mild.
The allergic reactions can affect the skin and create conditions that include eczema, hives and angioedema, including lip, face and eye swelling.
Allergens and Allergic Reactions
Different individuals have different responses to food allergens. These allergens can be linked to constipation, diarrhoea and blood in the stools or in vomiting. The most serious result of an allergic reaction is anaphylaxis, a life threatening type of allergic reaction. Anaphylaxis involves the whole body and causes a number of serious complications, which can lead to death. Some of the anaphylaxis symptoms include abdominal pain, cough, chest pain, dizziness, slurred speech, skin rashes, anxiety, unconsciousness and difficulty swallowing or breathing.
As per a 2010 study, it is found that 44% of the population suffers from allergies and 48% from more than one type of allergy. Food allergies generally occur in children and infants. Eggs, nuts, shellfish and wheat are a few of the allergens that are more likely to cause problems for longer and severe reactions.
Allergy Support Supplements
If a lot of food groups are excluded from the diet to avoid allergy, it becomes important that a dietician checks the adequacy of the diet and also suggests supplements to help the patient to overcome their deficiencies.
You should be concerned about your health and take good supplements that help in providing allergy support. Always try to deal with your allergies with natural remedies. A variety of supplements are available to help you in supporting your most common needs for allergy support. Generally these supplements are a rich source of vitamin E and Omega-3 fatty acids and help protect from rigorous allergic reactions.
