Why is fluid replacement necessary in diabetic ketoacidosis?

Fluid replacement is necessary in diabetic ketoacidosis because patients have lost large amounts of electrolytes and water from their bodies and require prompt rehydration. The treatment principles for diabetic ketoacidosis are as follows: First, establish two intravenous lines—one for fluid replacement and the other for intravenous medication administration. If the patient develops symptoms such as hypotension or shock, colloidal solutions should be used. Insulin must be appropriately administered under medical supervision, with regular follow-up evaluations to monitor disease progression and promote recovery.
