Euglycemic Diabetic Ketoacidosis Precipitated by a Keto Diet: Importance of Dietary History in Diagnosis

Diabetic ketoacidosis (DKA) is one of the serious complications of diabetes, especially type 1. It is defined by the triad of hyperglycemia (>250 mg/dL [>13.9 mmol/L]), high anion-gap metabolic acidosis, and increased plasma ketones. Euglycemic ketoacidosis is characterized by DKA without hyperglycemia. We present a rare case of a 28-year-old type 1 diabetic male, presenting with abdominal pain, fatigue, and dizziness after one week of starting a keto diet. He was diagnosed with euglycemic DKA, managed with DKA protocol and given detailed dietary counselling to avoid the keto diet in future.
