Diagnosis is often delayed or misdiagnosed due to its rarity in the western world and subtle features of hyperthyroidism on initial presentation. Here we present the case of a 25-year-old man who presented to the emergency department (ED) with sudden onset weakness of bilateral upper and lower extremities. His labs revealed hypokalaemia with elevated T4 and suppressed thyroid-stimulating hormone and he was diagnosed with thyrotoxic periodic paralysis. He was treated with potassium repletion, atenolol and methimazole with complete reversal of his paralysis within the next day. Unfortunately, he failed to keep the follow-up appointment after discharge, ran out of his methimazole and landed up in the ED again.<\/jats:p>","DOI":"10.1136\/bcr-2016-218951","type":"journal-article","created":{"date-parts":[[2017,1,30]],"date-time":"2017-01-30T10:30:57Z","timestamp":1485772257000},"page":"bcr2016218951","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Paralysis that easily reverses: a case of thyrotoxic periodic paralysis"],"prefix":"10.1136","volume":"2017","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3340-6106","authenticated-orcid":false,"given":"Niranjan","family":"Tachamo","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Reading Health System, West Reading, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saroj","family":"Lohani","sequence":"additional","affiliation":[{"name":"Reading Hospital and Medical Center, Reading, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salik","family":"Nazir","sequence":"additional","affiliation":[{"name":"Reading Hospital and Medical Center, Reading, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noelle","family":"Juliano","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Reading Health System, West Reading, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,1,30]]},"reference":[{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.1","first-page":"118","article-title":"Thyrotoxic hypokalemic periodic paralysis presenting with paraparesis","volume":"9","author":"Do\u011fan","year":"2013","journal-title":"Nobel Med"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.2","first-page":"67","article-title":"Thyrotoxic hypokalemic periodic paralysis is a rare but potentially fatal emergency: case report and literature review","volume":"103","author":"G\u00f3mez-Torres","year":"2011","journal-title":"Boletin Asoc Medica P R"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jemermed.2013.08.104"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.4","doi-asserted-by":"publisher","DOI":"10.3121\/cmr.2009.816"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.5","first-page":"274","article-title":"Thyrotoxic periodic paralysis: clinical and molecular aspects","volume":"43","author":"Falhammar","year":"2013","journal-title":"Endocrine"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.6","doi-asserted-by":"publisher","DOI":"10.1177\/0885066609358849"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.7","first-page":"487","article-title":"Thyrotoxic hypokalemic periodic paralysis: two case reports and a brief review of literature","volume":"77","author":"Shah","year":"2013","journal-title":"Conn Med"},{"key":"2025082707361082000_2017.jan30_1.bcr2016218951.8","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2006-0356"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2016-218951","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T14:36:17Z","timestamp":1756305377000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2016-218951"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,30]]},"references-count":8,"alternative-id":["10.1136\/bcr-2016-218951"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2016-218951","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2017,1,30]]}}}
