Diabetic Ketoacidosis(DKA)
Definition
A life-threatening medical emergency that occurs when severe insulin deficiency causes the body to break down fat at an accelerated rate, producing ketones that accumulate in the blood and make it dangerously acidic (pH below 7.3). DKA primarily affects people with type 1 diabetes and is characterized by blood glucose above 250 mg/dL, blood ketones above 3.0 mmol/L, nausea, abdominal pain, and fruity-smelling breath. CGMs with high glucose alerts help prevent DKA by warning users when glucose exceeds 250 mg/dL, enabling early intervention before ketone levels become dangerous.
Why “Diabetic Ketoacidosis” Matters for Glucose Monitoring
Understanding diabetic ketoacidosis is essential for anyone using or evaluating a continuous glucose monitor. This concept directly affects how CGM devices are designed, how glucose data is interpreted, and how clinical decisions about blood sugar management are made. Medical terms related to glucose physiology help patients and clinicians communicate effectively about blood sugar patterns, treatment goals, and the clinical significance of CGM data.
This term is particularly relevant to 2 CGM products in our database. Understanding DKA helps you compare devices more effectively and choose the right continuous glucose monitor for your specific needs.
