What is a classic symptom of Diabetic Ketoacidosis (DKA)?

In Diabetic Ketoacidosis (DKA), hyperglycemia is a defining characteristic and often manifests with blood glucose levels exceeding 250 mg/dL. DKA typically arises in individuals with type 1 diabetes, often triggered by inadequate insulin, infection, or stress. The lack of insulin leads to an inability of glucose to enter the cells, causing the body to resort to fat metabolism for energy. This results in the production of ketones, causing metabolic acidosis and increased blood glucose levels.

While elevated blood pressure, low body temperature, and increased appetite may occur in various conditions or at different stages of illness, they are not hallmark signs of DKA. Elevated blood pressure may be seen in stress responses or other medical conditions. Low body temperature is not commonly associated with DKA; patients often present with normal or elevated temperature due to infection. Increased appetite might occur before glucose levels significantly rise but typically, patients with DKA experience decreased appetite due to nausea and a sick feeling.

Understanding the critical role of hyperglycemia in diagnosing DKA aids in recognizing the condition promptly and initiating appropriate treatment to prevent severe complications.
