1. What this disease is

Type 2 diabetes guide is a common condition that benefits from early diagnosis, clear education, and a structured care plan.

2. Common causes and risk factors

• Insulin resistance with gradual beta-cell dysfunction.
• Risk factors: excess adiposity, family history, prediabetes, sleep disruption, and low activity.
• Contributors: social determinants, food insecurity, and medication adherence barriers.

3. Typical symptoms

• Polyuria, polydipsia, blurry vision, fatigue, recurrent infections; may be asymptomatic early.

4. Diagnosis and evaluation

• Confirm diagnosis with guideline-based history, exam, and indicated testing.
• Screen for severity, complications, and high-risk comorbid conditions.
• Identify social or access barriers that could affect treatment success.

5. Treatment (non-pharmacologic)

• Nutrition pattern that lowers glycemic load and supports sustainable weight loss.
• 150+ minutes/week aerobic activity plus resistance training 2–3 times/week.
• Sleep optimization, tobacco cessation, and structured self-monitoring education.

6. Treatment (pharmacologic)

• First-line: metformin (if tolerated/appropriate).
• Cardiorenal priorities: SGLT2 inhibitor and/or GLP-1 receptor agonist when indicated.
• Add agents by A1C, hypoglycemia risk, weight goals, and comorbid ASCVD/HF/CKD.

7. Monitoring and follow-up

• A1C every ~3 months until stable, then every 6 months.
• Renal function, UACR, blood pressure, lipids, eye/foot screening, and hypoglycemia risk.

8. Practical counseling points

• Give patients a clear “what to do today / when to call / when to seek urgent care” plan.
• Use teach-back to confirm understanding of treatment goals and medication instructions.
• Simplify regimens when possible to improve adherence and outcomes.

9. Red flags and escalation

• Escalate care urgently for severe or rapidly worsening symptoms.
• Reassess diagnosis if expected response does not occur within the anticipated timeline.

10. Guideline references

• American Diabetes Association (ADA) Standards of Care.
• KDIGO diabetes and CKD guidance.
• ACC/AHA prevention guidance for cardiometabolic risk.
