What is a primary characteristic of diabetes ketoacidosis?

A primary characteristic of diabetic ketoacidosis (DKA) is persistent hyperglycemia. In this condition, the body experiences significantly elevated blood sugar levels due to insulin deficiency, which prevents glucose from entering the cells. As a result, the body cannot utilize glucose effectively for energy and turns to fat metabolism instead, leading to the production of ketones. This situation results not only in high blood sugar levels but also in a state of acidosis due to the accumulation of ketones in the bloodstream. Recognizing persistent hyperglycemia is essential for diagnosing and managing DKA, as it indicates the severity of insulin deficiency and the need for immediate medical intervention. This aligns with the understanding that DKA often presents with substantial hyperglycemia, frequently exceeding 250 mg/dL.
