Which symptom is NOT associated with diabetic ketoacidosis (DKA)?

Diabetic ketoacidosis (DKA) is a serious complication of diabetes characterized by hyperglycemia, ketonemia, and metabolic acidosis. It manifests through a variety of symptoms as the body reacts to the lack of insulin and the buildup of ketones. Polydipsia, dehydration, and a fruity smell on the breath are classic indicators of DKA.

Polydipsia occurs as a response to hyperglycemia, where excess glucose in the bloodstream leads to increased urination (polyuria), resulting in dehydration. As the body loses fluids and becomes dehydrated, the individual feels an increased thirst.

Dehydration is a significant concern in DKA because the excessive urination and loss of fluids can lead to a significant reduction in body water levels. This dehydration can cause symptoms such as dry mouth, skin turgor changes, and further contribute to the overall distress in the body.

The fruity smell on the breath, reminiscent of acetone, is characteristic due to the accumulation of ketones in the blood, which are excreted via breath. This distinctive scent is a direct result of the metabolic processes that occur during DKA when the body shifts to fat metabolism in the absence of adequate insulin.
