Clinical features included muscle weakness, leg paralysis, and ECG changes. Blood tests revealed severe hypokalaemia (P-potassium 2.0 mmol\/l; ABG 1.5 mmol\/l) and elevated creatine kinase levels. Treatment with intravenous potassium and fluids led to recovery. This case report highlights the risk of electrolyte disturbances from high caffeine intake and the need to inquire about energy drink consumption in patients with unexplained hypokalemia.<\/jats:p>","DOI":"10.61409\/v11250922","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T06:21:42Z","timestamp":1779344502000},"page":"1-5","source":"Crossref","is-referenced-by-count":0,"title":["Energy drink-induced severe hypokalemia and rhabdomyolysis"],"prefix":"10.61409","author":[{"given":"Fie Holst","family":"Jensen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Bastholm","family":"Olesen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"40208","published-online":{"date-parts":[[2026,5,18]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Breda JJ, Whiting SH, Encarna\u00e7\u00e3o R, et al.
