Abstract

Sodium–glucose cotransporter (SGLT) inhibitors are new oral antidiabetes medications shown to effectively reduce glycated hemoglobin (A1C) and glycemic variability, blood pressure, and body weight without intrinsic properties to cause hypoglycemia in people with type 1 diabetes. However, recent studies, particularly in individuals with type 1 diabetes, have demonstrated increases in the absolute risk of diabetic ketoacidosis (DKA). Some cases presented with near-normal blood glucose levels or mild hyperglycemia, complicating the recognition/diagnosis of DKA and potentially delaying treatment. Several SGLT inhibitors are currently under review by the U.S. Food and Drug Administration and European regulatory agencies as adjuncts to insulin therapy in people with type 1 diabetes. Strategies must be developed and disseminated to the medical community to mitigate the associated DKA risk. This Consensus Report reviews current data regarding SGLT inhibitor use and provides recommendations to enhance the safety of SGLT inhibitors in people with type 1 diabetes.

  • Risk factors for DKA in individuals with type 1 or type 2 diabetes treated with SGLT inhibitors include very-low-carbohydrate diets, prolonged fasting, dehydration, excessive alcohol intake, and other common precipitating factors.

    “Risk factors for DKA in individuals with either type 1 or type 2 diabetes treated with SGLT inhibitors include very-low-carbohydrate diets, prolonged fasting, dehydration, excessive alcohol intake, and other common precipitating factors (84,236).”

    From 9. Pharmacologic Approaches to Glycemic Treatment: Standards of Care in Diabetes—2025 (2025) · cites this paper as [84]

    In Patient Selection (Table 2; page not provided), the paper lists reduced carbohydrate intake, excessive alcohol use, dehydration, and other DKA risk factors during SGLT inhibitor therapy. The Background section also links prolonged fasting to ketosis. The consensus addresses patients with type 1 diabetes, however, so it does not establish this risk-factor list for patients with type 2 diabetes. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • No risk mitigation strategies have been proven to lower the risk of DKA.

    “While no risk mitigation strategies have been proven to lower the risk of DKA, a consensus statement on SGLT2 inhibitors and DKA suggested careful patient selection, appropriate insulin dose adjustment to avoid insulinopenia, starting with a low dose of SGLT2 inhibitors, and regular ketone measurements with prompt action to address elevated values as sensible precautions aimed at preventing DKA (”

    From The management of type 1 diabetes in adults. A consensus report by the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) (2021) · cites this paper as [216]

    The Patient Selection, Insulin Dose Adjustments, Initiation and Dosing, and Ketone Monitoring sections recommend the precautions listed in the citing sentence. The Research Questions section says there is no evidence that daily ketone monitoring prevents DKA, but does not establish the broader claim that no risk-mitigation strategy has been proven to lower risk. The Initiation and Dosing section also reports lower DKA rates with lower SGLT inhibitor doses in clinical trials. Page numbers were not available in our copy. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • There are multiple proposed pathways through which SGLT inhibition results in ketosis, such as increased production due to reduction in insulin doses, increases in glucagon levels leading to increased lipolysis and ketone production, and decreased renal clearance of ketones.

    “There are multiple proposed pathways through which SGLT inhibition results in ketosis (increased b-hydroxybutyrate and acetoacetate), such as increased production due to reduction in insulin doses, increases in glucagon levels leading to increased lipolysis and ketone production, and decreased renal clearance of ketones (310,311).”
  • Individuals with type 1 diabetes and insulin-deficient type 2 diabetes are at increased risk for DKA with SGLT inhibitor therapy.

    “Individuals with type 1 diabetes (84,236) and insulin-deficient type 2 diabetes are at increased risk for DKA with SGLT inhibitor therapy.”
  • Adjunctive use of SGLT inhibitors in adults with type 1 diabetes increases the risk of DKA by an absolute rate of about 4% per year.

    “Adjunctive use of sodium-glucose cotransporter (SGLT) inhibitors (see below) in adults with type 1 diabetes increases the risk of DKA by an absolute rate of about 4% per year, suggesting the need for intensive diabetes self-management education and monitoring (216,217).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
