Diabetes ketoacidosis is a result of:

Diabetic ketoacidosis (DKA) occurs primarily due to insufficient insulin in the body, which leads the body to utilize fat as an alternative energy source. When insulin levels are low, glucose cannot enter the cells, prompting the liver to break down fat stores for energy. This process produces ketones as a byproduct. An accumulation of these ketones leads to metabolic acidosis, which is a hallmark of DKA.

In this metabolic state, the insufficient insulin results in high blood glucose levels, combined with the production of ketones, which ultimately causes the characteristic complications seen in DKA, such as dehydration and electrolyte imbalances. The presence of high glucose levels does contribute to DKA but is a consequence of the insulin deficiency rather than a direct cause. Thus, the correct answer accurately describes the underlying mechanism of DKA.
