The majority of food allergies in children are not severe and will disappear over time. The most common triggers are chicken eggs, cow&#8217;s milk, peanuts and hazelnuts. Less common triggers include seafood, sesame and soy, fish and wheat. Peanuts and hazelnuts, seeds and seafood are the main causes of lifelong allergy.<\/p>\n<p>Some food allergies can be severe, causing life\u2011threatening reactions known as anaphylaxis, which occur within 30 minutes of eating.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What is food allergy?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Some people react to what doctors call a hypersensitivity reaction when eating certain foods or additives. For a negative reaction to be called food hypersensitivity, an individual must have specific symptoms, namely:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">They appear when the person eats the food that is a source of sensitisation for them.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">They disappear or decrease when the person avoids the allergenic food.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">They reappear when the problem food is given again to the person with food allergy.<\/span><\/p>\n<\/li>\n<\/ul>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What are the symptoms of food allergy?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Symptoms of food allergy usually include: hives, swelling around the mouth, and vomiting. Other symptoms include a runny or blocked nose, stomach pain, or diarrhoea.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What are the dangerous symptoms of food allergy?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Symptoms of acute allergic reactions (anaphylaxis) include severe difficulty breathing and respiratory dysrhythmia, and may include any of the following symptoms:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Difficulty breathing.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Swollen tongue.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Swelling or constriction of the larynx.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Difficulty speaking, a hoarse voice, or persistent coughing.<\/span><\/p>\n<\/li>\n<\/ul>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>When does food allergy develop?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Food allergy can develop at any age, but it most commonly affects children under five years of age.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>How do we diagnose food allergy?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Accurate diagnosis of food allergy is a specialised procedure that requires considerable clinical experience. Currently, there are a number of diagnostic tests and procedures available to doctors, including:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Skin prick test.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Blood tests.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Challenge testing \u2013 among the tests and procedures used to diagnose food allergy. All current diagnostic tests have advantages and disadvantages.<\/span><\/p>\n<\/li>\n<\/ul>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>Does food allergy run in families?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">In general, parents of children with food allergy are not prone to such allergies. However, if a family has one child with food allergy, their siblings are at slightly higher risk of having a food allergy themselves, although the risk remains relatively low.<\/span><br \/>\n<span style=\"font-size: 14pt;\">Some parents want to have their other children screened for food allergies. If the test is negative, it may be reassuring, but it does not mean that the other child will not develop an allergy in the future. If the test is positive, it is not always clear whether the result definitely indicates an allergy.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>Does food allergy persist as people get older?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">The majority of children allergic to cow&#8217;s milk, wheat, soy or eggs will be able to tolerate these foods by the time they reach school age, often before starting school. In contrast, allergy to peanuts, hazelnuts, seeds and seafood persists in the vast majority of affected children. When food allergy first develops in adults, it usually persists.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What is meant by food intolerance?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">The phenomenon of food intolerance is difficult to understand. Sometimes substances within foods can increase the frequency and severity of migraines, skin rashes, or stomach upset resulting from irritable bowel syndrome.<\/span><br \/>\n<span style=\"font-size: 14pt;\">Foods are made up of protein, carbohydrates, fats and various nutrients, as well as a number of natural chemicals. These chemicals can cause food intolerance. Coincidence can also cause a lot of confusion in this matter, since we spend many waking hours eating or drinking.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Food allergy affects about 1 in every 20 children and about 1 in 100 adults.
