The main idea here is that patients with diabetic ketoacidosis are severely volume-depleted from osmotic diuresis and vomiting, so restoring intravascular volume is the immediate priority. Starting IV isotonic fluids (usually normal saline) rapidly improves tissue perfusion, renal function, and overall hemodynamic stability, which is essential before moving on to insulin therapy or electrolyte corrections. This fluid resuscitation sets the stage for the rest of the treatment by rehydrating the body, helping to dilute glucose and ketones, and supporting better organ function as you address the metabolic disturbances.

Insulin therapy is important, but it is typically started only after there is some volume restoration because giving insulin without adequate fluids can worsen circulatory instability and shift potassium into cells, potentially creating dangerous electrolyte changes. Potassium management is crucial as well, but it is guided by lab values and usually addressed after fluids are underway and insulin is being considered. Oral hydration isn’t suitable in the acute hospital setting because IV fluids ensure reliable and rapid rehydration.
