Therefore, their potential for inducing ketoacidosis, even in the presence of normal glucose levels, requires careful monitoring. We describe the case of a 78-year-old woman with type 2 diabetes treated with the SGLT-2 inhibitor dapagliflozin and the biguanide metformin, who presented after several days of reduced food and fluid intake due to nausea and diarrhoea to the emergency department. A few hours after admission to the medical ward with a working diagnosis of infectious gastroenteritis her condition deteriorated, and mottling served as an early sign of life-threatening euglycemic ketoacidosis. The mottling score increased in parallel with the National Early Warning Score (NEWS). She was treated with intravenous fluids, continuous insulin therapy and supportive measures, resulting in rapid clinical improvement. This report highlights the importance of early recognition to prevent serious complications and underscores that mottling might be a valuable early sign in addition to classical tools such as the NEWS. Although rare, euglycemic ketoacidosis can be precipitated by factors such as starvation, dehydration or infections in patients taking SGLT-2 inhibitors. The risk might be higher in individuals on SGLT-2 inhibitors and metformin. Timely intervention and metabolic correction are essential for improving outcomes in these patients, particularly when they present with atypical symptoms.<\/jats:p>","DOI":"10.12890\/2025_005210","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T11:02:41Z","timestamp":1742814161000},"source":"Crossref","is-referenced-by-count":1,"title":["Mottling as an early sign of euglycemic ketoacidosis induced by SGLT-2 inhibitors"],"prefix":"10.12890","volume":"12","author":[{"given":"Besard","family":"Memeti","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Klinic Hirslanden, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix","family":"Brombacher","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Klinic Hirslanden, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludwig","family":"Perger","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Klinic Hirslanden, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Russmann","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Klinic Hirslanden, Zurich, Switzerland; Drugsafety.ch, Kuesnacht, Switzerland; University of Nicosia Medical School, Engomi, Cyprus"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10397","published-online":{"date-parts":[[2025,3,21]]},"reference":[{"key":"10.12890\/2025_005210_ref1","doi-asserted-by":"crossref","unstructured":"
