To the Editor: A 64‐year‐old woman presented to our emergency department with progressively reduced consciousness over 3 days. This was preceded by 2 days of vomiting and diarrhoea. She had been systemically well before this, with no acute medical issues. She had type 2 diabetes and had been commenced on combination 10 mg empagliflozin and 5 mg linagliptin a year ago after having experienced diarrhoea with metformin. Her most recent glycated haemoglobin level was 58 mmol/mol (reference interval [RI], 20–42 mmol/mol). She had also been trialling the Atkins diet for about 2 months before presentation.
