Diabetic ketoacidosis (DKA) is a life-threatening complication of diabetes that demands immediate and effective medical intervention. Prompt recognition and treatment are crucial, as DKA can rapidly progress to severe dehydration, electrolyte imbalances, and organ failure if not addressed. For individuals with diabetes, understanding DKA treatment protocols is essential for both emergency preparedness and long-term health management. This comprehensive guide outlines the latest evidence-based approaches to DKA treatment, prevention strategies, and the critical role of ongoing diabetes care.
The primary goals of DKA treatment are to correct dehydration, reverse ketosis and acidosis, restore electrolyte balance, and identify and treat any underlying causes. Hospitalization is typically required, with a multidisciplinary team—including endocrinologists, emergency physicians, and diabetes specialists—working together to ensure optimal outcomes. Patients and caregivers should also be aware of preventive measures and post-recovery care to minimize the risk of recurrence and other diabetes-related complications.
Diabetic Ketoacidosis Treatment
Initial Assessment and Stabilization
The first step in managing DKA is rapid assessment and stabilization. Upon arrival at the emergency department, patients are evaluated for airway, breathing, and circulation. Intravenous (IV) access is established, and initial blood tests are ordered to confirm DKA, assess severity, and identify precipitating factors such as infection, myocardial infarction, or medication non-compliance. Immediate priorities include monitoring vital signs, mental status, and urine output, which are essential for guiding therapy and detecting complications early.
Fluid replacement is the cornerstone of initial DKA management. Most patients are significantly dehydrated due to osmotic diuresis and vomiting. IV fluids—typically 0.9% sodium chloride (normal saline)—are administered rapidly to restore circulatory volume, improve renal perfusion, and lower blood glucose levels. The initial bolus is often 1–1.5 liters in the first hour, followed by adjusted rates based on clinical response, corrected sodium levels, and ongoing losses. In cases of hypovolemic shock, fluid resuscitation is even more aggressive.
Insulin Therapy and Ketosis Reversal
After initial fluid resuscitation, intravenous insulin therapy is started to suppress ketogenesis, reduce blood glucose, and correct acidosis. A fixed-rate IV insulin infusion (commonly 0.1 units/kg/hour) is recommended, with dose adjustments based on hourly blood glucose and ketone monitoring. Insulin should not be delayed, but it is generally initiated after starting fluids to avoid rapid shifts in potassium and glucose.
The targets for metabolic correction during DKA treatment are:
1. Reduction of blood ketones by at least 0.5 mmol/L per hour
2. Increase of venous bicarbonate by 3.0 mmol/L per hour
3. Reduction of blood glucose by 3.0 mmol/L per hour
4. Maintenance of potassium between 4.0 and 5.5 mmol/L
As blood glucose approaches 200–250 mg/dL (11.1–14 mmol/L), dextrose is added to IV fluids to prevent hypoglycemia while continuing insulin to clear ketones and resolve acidosis235. Insulin therapy is continued until DKA resolves, defined by normalization of pH, bicarbonate, and ketone levels, as well as the patient’s ability to eat and drink.
Electrolyte Management and Complication Monitoring
Electrolyte replacement is a vital component of DKA treatment, as insulin and fluids can cause rapid shifts in potassium, sodium, and phosphate. Potassium levels must be closely monitored and replaced as needed to prevent life-threatening arrhythmias. Insulin should not be started if potassium is below 3.3 mmol/L; instead, potassium replacement is prioritized until safe levels are achieved.
Other supportive measures include magnesium and phosphate replacement if deficiencies are detected, DVT prophylaxis in immobilized patients, and careful monitoring for complications such as cerebral edema, fluid overload, and acute kidney injury. Hourly monitoring of blood glucose, ketones, and vital signs is essential, with venous blood gases and electrolytes checked every 2–4 hours. Senior or specialist input should be sought if DKA does not resolve within 24 hours or if complications arise.
Transition to Subcutaneous Insulin and Discharge Planning
Once DKA has resolved and the patient is able to tolerate oral intake, the transition from IV to subcutaneous insulin is initiated. The diabetes specialist team should oversee this process, ensuring that long-acting (basal) insulin is restarted before discontinuing IV insulin to prevent rebound hyperglycemia. Patients are educated on injection technique, blood glucose monitoring, and sick day management.
Discharge planning includes reviewing the precipitating cause of DKA, optimizing the outpatient diabetes regimen, providing written “sick day rules,” and arranging follow-up with the diabetes care team. Patients should be counseled on recognizing early symptoms of DKA, the importance of never omitting insulin, and the use of ketone testing during illness or high blood sugars. Access to continuous glucose monitoring (CGM) or flash glucose monitoring may be offered to improve glycemic control and reduce recurrence risk.

Essential Tips for Diabetic
Never Omit Insulin: Even during illness or fasting, continue your long-acting insulin to prevent DKA.
Monitor Blood Glucose Frequently: Check your blood sugar at least 3–4 times daily, and more often if you’re ill or have symptoms of high blood sugar
Test for Ketones: Use blood or urine ketone tests when blood sugar is high (>250 mg/dL), when you’re sick, or when symptoms of DKA appear
Stay Hydrated: Drink water or sugar-free fluids regularly, especially when sick or vomiting, to prevent dehydration
Follow Sick Day Rules: Have a written plan for insulin adjustment, ketone testing, and when to seek medical help during illness
Recognize Early Symptoms: Be alert for excessive thirst, frequent urination, nausea, abdominal pain, or confusion, and seek help promptly
Work Closely with Your Care Team: Keep regular appointments, review your management plan, and ask about CGM or flash monitoring for better control
Understanding the Importance of Proper Diabetic Fit
Proper diabetic footwear is a vital, yet often overlooked, aspect of diabetes management—especially for those recovering from DKA or at risk for complications. Diabetic shoes and custom orthotics are designed to reduce pressure, prevent ulcers, and accommodate foot deformities caused by neuropathy or poor circulation.
Why Proper Fit Matters:
Prevents Ulcers and Injuries: Diabetic shoes reduce friction, shear, and pressure points, lowering the risk of blisters and ulcers that can lead to infections or amputations.
Supports Foot Health: Properly fitted shoes accommodate changes in foot shape and protect sensitive areas, especially in those with loss of protective sensation (LOPS)
Improves Mobility and Comfort: Enhanced cushioning, arch support, and motion control reduce fatigue and pain, promoting independence and activity
Reduces Hospitalizations: Studies show that therapeutic footwear significantly lowers the incidence of foot ulcers and re-ulceration in high-risk patients.
Tips for Diabetic Footwear:
1. Always get professionally fitted shoes and orthotics
2. Replace shoes regularly and inspect them for wear or damage
3. Wear shoes indoors and outdoors; avoid walking barefoot
4. Use moisture-wicking, seamless socks to further protect your feet
