Initial Management Strategies for Diabetes
The initial management of diabetes should include metformin as the preferred first-line pharmacological treatment for patients with normal renal function, along with comprehensive lifestyle modifications including diet, exercise, and diabetes self-management education. 1
Initial Assessment and Classification
Perform a complete medical evaluation to:
- Classify diabetes type (Type 1 vs Type 2)
- Detect existing diabetes complications
- Review previous treatments (if applicable)
- Formulate a management plan 2
Key laboratory tests:
- HbA1c
- Fasting plasma glucose
- Renal function tests
- Lipid profile
- Liver function tests
Pharmacological Management
For Most Newly Diagnosed Type 2 Diabetes Patients:
Metformin:
- Start at 500mg once or twice daily
- Gradually titrate to 2,000mg per day as tolerated 1
- Monitor for gastrointestinal side effects and renal function
For patients with marked hyperglycemia (blood glucose ≥600 mg/dL) or high A1C (≥8.5%):
- Begin insulin therapy immediately (starting at 0.5 units/kg/day)
- Add metformin concurrently
- Titrate insulin every 2-3 days based on blood glucose monitoring 1
For patients with ketosis/ketoacidosis:
Lifestyle Modifications
Nutrition Therapy:
- Recommend a DASH-style eating pattern
- Reduce sodium and increase potassium intake
- Consider referral to a registered dietitian for individualized medical nutrition therapy 1
Physical Activity:
Weight Management:
Diabetes Self-Management Education (DSME)
- Essential component of initial management 2
- Include education on:
- Blood glucose monitoring techniques
- Recognition and management of hypoglycemia
- Medication administration (especially insulin if prescribed)
- Problem-solving skills for all aspects of diabetes management 1
Monitoring and Follow-up
- Monitor HbA1c every 3 months initially
- Assess medication adherence, side effects, and complications risk at follow-up visits
- Intensify treatment if glycemic targets are not met 1
- Regular self-monitoring of blood glucose, especially for patients on insulin therapy 5
Special Considerations
- Insulin administration safety: Never share insulin pens, needles, or syringes between patients due to risk of blood-borne pathogen transmission 5
- Hypoglycemia risk: Educate patients to recognize and manage hypoglycemia, especially those on insulin therapy 5
- For Type 1 diabetes: Consider screening for autoimmune diseases (thyroid dysfunction, celiac disease) 2
- For youth with obesity and Type 2 diabetes: Consider GLP-1 receptor agonists if glycemic targets aren't met with metformin 1
Comprehensive Care Team
- Assemble a multidisciplinary team that may include:
The evidence strongly supports that early, aggressive management of diabetes with appropriate medication and lifestyle modifications can significantly reduce the risk of complications and improve long-term outcomes 3, 4.
