RESUMO
OBJECTIVE: We report a case of a successful reimplementation of a very low carbohydrate ketogenic diet (VLCKD) after a case of euglycemic diabetic ketoacidosis (euDKA). METHODS: A 42-year-old female with a history of type 2 diabetes mellitus on a self-administered VLCKD was prescribed a sodium-glucose co-transporter 2 (SGLT2) inhibitor. Two weeks after initiation, she presented with nausea and vomiting and was found to be in euDKA which was treated with fluid resuscitation, insulin infusion, and cessation of the SGLT2 inhibitor. She was discharged on insulin and instructed not to resume a VLCKD. RESULTS: After discharge, the patient experienced rapid weight gain and deteriorating glycemic control and desired to resume a VLCKD. She was referred to a university-based medical weight loss clinic that specializes in a VLCKD. The patient was monitored with daily contact via the electronic health record's patient portal and serial laboratory testing while her carbohydrate intake was slowly reduced and her insulin titrated off. She has safely remained in ketosis for 2 years without a further episode of euDKA. CONCLUSION: As the clinical use of SGLT2 inhibitors and the VLCKD both become increasingly common, it is vital for practitioners to be aware that the combination can lead to euDKA. We present a case of successfully resuming a VLCKD after recovering from euDKA and cessation of SGLT2 inhibitor therapy.
