For those of us who suffer from allergies, it sometimes feels like we are being attacked by unseen forces lingering all around us.\u00a0 The very air we breathe, the food we eat, the beautiful flowers we see and the beloved pets we hold in our arms can be sources of irritation and illness. Yet many of us don\u2019t understand what causes allergic reactions even as we struggle to minimize their effects.\u00a0 Dr. Dayna Lee Lucuab-Fegurgur (or simply referred by colleagues as “Dr. L”) is an internal medicine doctor at University Health Partners of Hawaii sub-specializing in Allergy and Immunology.\u00a0 In a recent conversation, she offered some explanations and some advice about how to get help for this medical condition that affects so many of us.<\/p>\n\n\n\n
Allergies, she tells us, occur when our bodies \u201cproduce an abnormal or over-reactive immune response to a substance. We call these substances \u2018allergens\u2019 and they can be anything from pollen to food or even medications. For the general population, these substances don\u2019t cause any type of reaction, but for someone with allergies, they can cause an over-reactive immune response. Their immune system will recognize the specific allergen as foreign and its reaction can manifest in different ways ranging from a runny nose and sneezing to, at the severe end of the spectrum, anaphylaxis.\u201d Anaphylaxis can bring about some very severe symptoms such as vomiting, difficulty breathing and shock, and if it is not treated right away may even result in death. <\/p>\n\n\n\n
\u201cAllergies can appear at any time in your life, even in infancy,\u201d Dr. L tells us, \u201cand some can wane with time.\u201d There are various theories explaining why and how allergies develop, \u201cbut basically to become allergic later in life, your body has become sensitized to the allergen over time with repeated exposure. Your body just decides to see it as foreign and develops an abnormal immune response for reasons not completely understood.\u201d And the reverse can happen as well. \u201cYour body may develop a tolerance to the allergen over time and lose its ability to recognize it as foreign. We can\u2019t predict that.\u201d<\/p>\n\n\n\n
Why do some people get allergies and some lucky souls never are afflicted with this condition? \u201cThere\u2019s definitely a genetic component,\u201d Dr. L says. \u201cYou may be predisposed to developing allergic diseases like asthma, allergic rhinitis, and eczema if there is a positive family history. Having one parent who has a history of allergies definitely increases your propensity to develop them as well by about 50%. If both parents have allergies, then there\u2019s an even higher chance that you will inherit some type of atopic condition.\u201d<\/p>\n\n\n\n
If you have the allergic type of asthma, allergies can trigger your asthma to flare, Dr. L says. \u201cNot all asthma is allergic, but a large proportion of people with asthma have allergic triggers. Asthma itself is a chronic condition of the lungs generally characterized by airway inflammation and obstruction which causes symptoms such as wheezing, shortness of breath, chest tightness and chronic cough.\u201d The allergic type of asthma usually develops in childhood, but if you develop it later in life, she says, allergic triggers may not be as prevalent. \u201cThere are other potential etiologies for late onset asthma.\u201d <\/p>\n\n\n\n
There are a number of theories as to why the number of people developing allergies has been increasing over time, Dr. L says. One, she refers to as \u201cthe hygiene hypothesis\u201d whereby in industrialized countries children aren\u2019t exposed to as many germs as they would have been in developing regions where the exposure can help train their immune systems to recognize the difference between harmful and harmless irritants. Also, in industrialized countries, \u201cwe\u2019ve had increased prevalence of antibiotic use over the years and this might alter the microflora or the flora of bacteria that are naturally occurring in our guts, which might possibly impact the development of allergies.\u201d<\/p>\n\n\n\n
Of course the world holds many different types of allergens, so where you live can impact your sensitivity to them due to the amount of allergen exposure, which can vary geographically. \u201cHere we have a lot of Bermuda grass pollen, but if you go to the East Coast, there may be more ragweed pollen, so depending upon where you are, the triggers might be different.\u201d<\/p>\n\n\n\n
While there is no cure for allergies or asthma, Dr. L assures us that \u201cthere are many, many treatment options and different modes of therapy to help manage the symptoms.\u201d Allergy shots, which have been proven to be quite effective for a lot of people, \u201cgive you small amounts of the allergen gradually increasing in dose over time and this procedure kind of changes the way your immune system responds to the allergen, so you don\u2019t have as many of the symptoms that come with it. These shots are specifically for inhalant allergens (things in the air that trigger nasal allergies and asthma). For specific dust mite allergy, they might also help with eczema.\u201d<\/p>\n\n\n\n
Depending on the particular allergens that are triggering your allergies, there are a lot of things we can do in our own environments to limit our exposure to them, such as trying to eliminate as much dust as possible in our homes. \u201cDust tends to be highly concentrated in carpets, upholstery, and in our beds and pillows.\u201d <\/p>\n\n\n\n
Dr. L urges people who suffer from allergies to see a doctor. \u201cIf you have trouble controlling your allergies, or you want to know exactly what you\u2019re allergic to, you should definitely see your local allergist.\u201d For those wanting more information, she recommends going to the American Academy of Allergy, Asthma & Immunology<\/a> (AAAAI) or the American College of Allergy, Asthma, and Immunology<\/a> (ACAAI) websites.<\/p>\n\n\n\n \u201cA lot of people have allergic rhinitis,\u201d she adds, \u201cand while this isn\u2019t a deadly disease, it does bother a lot of people and causes missed work days, missed school days, and can be a large financial burden which definitely impacts the quality of life for many people.\u201d<\/p>\n\n\n\n If you suffer from allergies, avoid triggering an allergic response from these major allergens: <\/p>\n\n\n\n June 28, 2021 — UHP Internal Medicine physician Dr. Dayna Lucuab-Fergurgur shares her expertise on allergies. <\/p>\n","protected":false},"author":14,"featured_media":15122,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"nf_dc_page":"","_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_hide_featured_image":false,"_jetpack_featured_image_duplicate_dismissed":0,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"nfd_image_url":"","nfd_onboarding_generated":"","footnotes":"","jetpack_post_was_ever_published":false},"categories":[1],"tags":[41],"class_list":["post-15121","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-department-of-internal-medicine"],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"https:\/\/i0.wp.com\/uhphawaii.org\/wp-content\/uploads\/2021\/06\/pexels-gustavo-fring-3983399-scaled.jpg?fit=2560%2C1707&ssl=1","_links":{"self":[{"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/posts\/15121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/users\/14"}],"replies":[{"embeddable":true,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/comments?post=15121"}],"version-history":[{"count":3,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/posts\/15121\/revisions"}],"predecessor-version":[{"id":15126,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/posts\/15121\/revisions\/15126"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/media\/15122"}],"wp:attachment":[{"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/media?parent=15121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/categories?post=15121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/uhphawaii.org\/index.php\/wp-json\/wp\/v2\/tags?post=15121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Dust mites<\/td> Put special dust-proof covers on pillows, mattresses and box springs, and remove and clean them frequently.
