He also suffered excessive flatulence as his body tried to expel the trapped air elsewhere.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Daryl did not think his inability to belch was a problem until he was in his mid-40s, when he started experiencing bloating, trapped wind, pain and constipation every day.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cI could not eat certain foods or have gassy drinks without turning into a pressure cooker. When it happened, I would get relief by self-inducing vomiting to expel the excess air. My colleagues could hear me gagging in the toilet,\u201d he said.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Daryl thought he had become lactose-intolerant and, because he loves his daily caffeine fix, started drinking kopi-o kosong, or black coffee.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">From 2018, Daryl started seeing \u201ca slew of GPs and specialists \u2013 <!-- -->at both<!-- --> private and public hospitals\u201d.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cI underwent <!-- -->(procedures)<!-- --> such as an endoscopy and a colonoscopy and was told that they couldn\u2019t really find anything serious. Some told me I had GERD while others said it was IBS <!-- -->(irritable bowel syndrome)<!-- -->,\u201d he said.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">GERD, which stands for gastroesophageal reflux disease, is a chronic digestive condition where stomach acid frequently flows back into the food pipe, or oesophagus, irritating its lining.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">IBS<!-- --> is a common, long-term digestive condition that affects the large intestine and how the gut works.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">The medication that Daryl was prescribed did not help his condition at all.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cAnd since tests did not turn up anything serious like cancer, life went on. Whenever I felt gassy or bloated, I continued to induce gagging to rid myself of the gas,\u201d he said, adding that he regularly used medicated oil to massage his stomach to help ease the gas.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">It was only two years ago that, while browsing online, Daryl learnt of a condition called retrograde cricopharyngeus dysfunction (RCPD) from a group on <!-- -->online forum<!-- --> Reddit.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cWhen I consulted a doctor in private practice and told him about RCPD, he said he had never heard of it before. To be fair, he was a gastroenterologist and not a specialist in ear, nose and throat. Again, the medication he prescribed did not work.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cSo another year passed, and my bloating got worse,\u201d Daryl said.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Applying medicated oil to his abdomen to relieve the gas became a nightly routine.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Not wanting to give up, Daryl continued his search on the internet, and this time he came across a paper on RCPD, written by ear, nose and throat specialist Leong Zhou Hao from the Singapore General Hospital.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cI told myself: \u2018This is the guy. I have finally found him!\u2019 So I went to the polyclinic for a referral letter. After so many years, I needed to reduce my financial \u2018damage\u2019,\u201d he said, laughing.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Leong, a consultant in the Department of Otorhinolaryngology at the hospital, confirmed that Daryl has RCPD, also known as \u201cno-burp syndrome\u201d, which is considered a relatively rare and underdiagnosed condition, primarily because it was formally identified only around 2019.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">He said humans swallow air while eating, drinking or talking.<\/p>\n<figure class=\"landscape inline-media-wrapper\" data-testid=\"inline-media-test-id\">\n<div class=\"flex flex-col items-start relative w-fit\"><picture><source media=\"(max-width: 480px)\" srcset=\"https:\/\/cassette.sphdigital.com.sg\/image\/straitstimes\/78091f5e4b1185d8f9fe45f80bc487236aba92697e998fd32ebbf8ae5d321c72?w=480\"\/><source media=\"(min-width: 481px) and (max-width: 720px)\" srcset=\"https:\/\/cassette.sphdigital.com.sg\/image\/straitstimes\/78091f5e4b1185d8f9fe45f80bc487236aba92697e998fd32ebbf8ae5d321c72?w=720\"\/><source media=\"(min-width: 721px and max-width: 3999px)\" srcset=\"https:\/\/cassette.sphdigital.com.sg\/image\/straitstimes\/78091f5e4b1185d8f9fe45f80bc487236aba92697e998fd32ebbf8ae5d321c72?w=900\"\/><source media=\"(min-width: 4000px)\" srcset=\"https:\/\/cassette.sphdigital.com.sg\/image\/straitstimes\/78091f5e4b1185d8f9fe45f80bc487236aba92697e998fd32ebbf8ae5d321c72\"\/><img decoding=\"async\" src=\"https:\/\/cassette.sphdigital.com.sg\/image\/straitstimes\/78091f5e4b1185d8f9fe45f80bc487236aba92697e998fd32ebbf8ae5d321c72\" alt=\"Daryl (left) was finally able to belch after SGH otorhinolaryngologist Leong Zhou Hao injected Botox into the sphincter muscle in his oesophagus, relaxing it so that he could burp.\" class=\"aspect-landscape flex items-start shrink-0 object-cover landscape article-landscape mobile:w-auto tablet:w-auto\" data-testid=\"image-test-id\" loading=\"lazy\"\/><\/picture><\/div><figcaption class=\"mobile:mx-16 tablet:mx-00 pt-08 pb-16\">\n<p class=\"inline text-secondary font-secondary-captions-baseline-regular\" data-testid=\"inline-media-caption-test-id\">Daryl was finally able to belch after SGH otorhinolaryngologist Leong Zhou Hao (right) injected Botox into the sphincter muscle in his oesophagus, relaxing it so that he could burp.<\/p>\n<p class=\"inline text-tertiary font-secondary-captions-baseline-regular\" data-testid=\"inline-media-credit-test-id\"> <!-- -->ST PHOTO: NG SOR LUAN<\/p>\n<\/figcaption><\/figure>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cWe have two sphincter muscles along our food passage \u2013 one right at the top and one at the bottom \u2013 and normally they are closed. When we eat, they are relaxed to let the food down. Many times the food that we eat produces gas, which travels back up the food passage, stretching the oesophagus.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cThis stretch is sensed by the brain, which triggers the muscle to relax, causing a burp,\u201d Leong explained.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">He added that for some reason the reflex is not developed in some people.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">According to medical literature, the exact prevalence of RCPD in the general population remains unknown, but limited preliminary data suggests it could affect up to 22% of people, with about 13% <!-- -->experiencing<!-- --> severe symptoms.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">To treat this condition, Leong said botulinum toxin, or <!-- -->commonly known as<!-- --> Botox, is injected into the sphincter muscle in the oesophagus to help relax it and \u201cforcibly allow the patient to burp\u201d.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Leong, who carried out the procedure while he was working in Australia, said the effect of each Botox injection lasts about three months, and the patient needs to return for another jab. But he would ask his patients to \u201cpractise burping\u201d in the hope that the reflex would redevelop.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">The surgeon carried out an endoscopy to make sure there was no blockage in Daryl\u2019s oesophagus before scheduling the Botox injection into his upper oesophageal sphincter muscle in March.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cI picked to go under general anaesthesia for the procedure so that Dr Leong could treat the site directly and I would be cured of my inability to burp,\u201d Daryl said.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">It has been six months since<!-- --> the procedure<!-- -->, and Daryl continues to burp comfortably without feeling pain or bloating in his abdomen.<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">\u201cI never knew that when I burp, I could smell the food I had eaten a few hours before. It was liberating. I would even say it was life-changing. Now I am happy that I can go back to drinking a latte without any issues.\u201d<\/p>\n<p class=\"text-primary font-tertiary-body-baseline-regular\" data-testid=\"article-paragraph-annotation-test-id\">Daryl also confessed that the happiest person after his treatment was his wife, \u201cfor obvious reasons\u201d, he added, laughing.<\/p>\n<\/div>\n<p><br \/>\n<center><br \/>\n<br \/><a href=\"https:\/\/www.straitstimes.com\/singapore\/health\/how-botox-changed-the-life-of-a-man-who-could-not-burp-for-52-years\" target=\"_blank\" rel=\"noopener\">Read Full Article At Source <\/a><br \/>\n<center\/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SINGAPORE \u2013 Daryl was 52 when he finally learnt how to burp in 2026. \u201cAll my life, I could not burp,\u201d the cybersecurity executive, who&#8230;<\/p>\n","protected":false},"author":1,"featured_media":89926,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"","fifu_image_alt":"","footnotes":""},"categories":[2611],"tags":[],"class_list":["post-89925","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-buzz-headlines","wpcat-2611-id"],"brizy_media":[],"_links":{"self":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/89925","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=89925"}],"version-history":[{"count":0,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/89925\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/media\/89926"}],"wp:attachment":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=89925"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=89925"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=89925"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
