DKA vs. HHS - A Comprehensive Comparison

Overview  
- Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS) are critical diabetic emergencies.  
- Both arise from insulin deficiency leading to hyperglycemia.  
- Early recognition and treatment are essential to reduce mortality.  

Similarities  
- Insulin deficiency is the primary cause.  
- Common triggers include infections, medication issues, and non-compliance.  
- Fluid resuscitation and insulin therapy are key to treatment.  

DKA: Key Features  
- Typically occurs in Type 1 Diabetes.  
- Rapid onset, often within 24 hours.  

DKA: Lab Findings:  
  - Blood glucose above 250 mg/dL.  
  - Low pH (below 7.3) and bicarbonate (below 18 mmol/L).  
  - Ketones present in blood and urine.  
  - Elevated anion gap.  

DKA: Clinical Signs:  
  - Nausea, vomiting, abdominal pain.  
  - Fruity breath (ketones).  
  - Kussmaul respirations (deep, labored breaths).  

HHS: Key Features  
- Typically occurs in Type 2 Diabetes.  
- Gradual onset.  

HHS: Lab Findings:  
  - Blood glucose above 600 mg/dL.  
  - Normal pH and bicarbonate.  
  - No significant ketones.  
  - Marked hyperosmolality.  

HHS: Clinical Signs:  
  - Severe dehydration.  
  - Neurological symptoms: confusion, seizures, coma.  

Comparison of Mortality  
- DKA mortality rate: Up to 8%.  
- HHS mortality rate: As high as 20%.  
- HHS affects older individuals with comorbidities, increasing vulnerability.  

Management - Initial Steps for Both:  
  - Rapid fluid resuscitation (1,000–1,500 mL of 0.9% saline in the first hour).  
  - Insulin therapy with frequent blood glucose monitoring.  
  - Monitor and correct potassium levels based on initial lab findings.  

Management - Key Differences in Focus:  
  - DKA: Treat acidosis and ketone production.  
  - HHS: Manage severe dehydration and hyperosmolality.  

Addressing Underlying Causes  
- Common triggers: infections, medication non-adherence, health conditions.  
- Treating root causes prevents recurrence.  
- Encourage a proactive and preventive approach in diabetes management.  

Prevention and Long-Term Care  
- Importance of access to affordable diabetes care.  
- Develop culturally sensitive education programs.  
- Promote health equity to address disparities in diabetes care.  
- Invest in research and technology, e.g., CGM, insulin pumps.  
​
Conclusion  
- DKA and HHS are life-threatening but manageable with proper care.  
- Early recognition and tailored management save lives.  
- Empower patients with knowledge, tools, and support for better outcomes.  
- Together, we can improve the future of diabetes care.
