Body mass index is inversely associated with capillary ketones at the time of colonoscopy: Implications for SGLT2i use

Abstract

Objective: Sodium–glucose cotransporter 2 inhibitors (SGLT2i) have been associated with diabetic ketoacidosis at the time of colonoscopy. This study aimed to identify factors associated with ketone concentrations in SGLT2i-treated type 2 diabetes compared with non-SGLT2i-treated diabetes, and those with impaired fasting glycaemia (IFG) and normoglycaemia. Design: Cross-sectional, multicentre, observational study June–December 2020 in four Australian tertiary hospitals. Participants: Capillary glucose and ketones were measured in people undergoing colonoscopy: 37 SGLT2i-treated and 105 non-SGLT2i-treated type 2 diabetes, 65 IFG and 151 normoglycaemia. Measurements: Body mass index (BMI), age,..
