  4. Steroid-induced hyperglycemia: NPH peaks with steroid peak; or short-acting basal-bolus
  5. Geriatric DM: less aggressive HbA1c (< 8 or < 8.5); avoid hypoglycemia at all costs

417.3.0.5 ⚙ ADA 2026 Treatment Algorithm (Simplified)

Lifestyle + Metformin (always; 陀非 CI)
  ↓ Stratify by comorbidity (NEW paradigm — CV/CKD priority)

CV高颚險 / ASCVD:
- 1st add: GLP-1 RA (proven CV) OR SGLT2 (proven CV)
- HFrEF/HFpEF → SGLT2 mandatory
- CKD eGFR > 20 + alb > 200 → SGLT2 mandatory
- Stroke/PAD → GLP-1 RA preferred

Obesity priority:
- GLP-1 RA (semaglutide highest)
- Tirzepatide (best class)
- Bariatric surgery if BMI > 40 or > 35 + comorbidity

HbA1c reduction priority (no comorbidity):
- Metformin → DPP-4 OR SU OR TZD OR GLP-1 OR SGLT2
- Cost considerations

Hypoglycemia avoidance:
- DPP-4, SGLT2, GLP-1 (no hypo mono)
- Avoid SU/glinide/insulin

Failure → add another class
- Avoid: SU + glinide; SU + insulin (without down-titrating)
- Insulin if HbA1c > 9% with symptoms / DKA

417.3.0.6 ⚙ T1DM Management Detailed

Basal-bolus:
- Total Daily Dose (TDD) = 0.5-1 U/kg
- Basal 50% (long-acting glargine/degludec)
- Bolus 50% (rapid lispro/aspart/glulisine)
- I:C ratio = 500/TDD (carb counting)
- Correction factor = 1500-1800/TDD (mg/dL drop per 1U)

Pump (CSII):
- Multiple basal rates
- Pre-programmed boluses
- Better TIR than MDI

AID (Hybrid closed-loop):
- Tandem t:slim X2 + Control-IQ + Dexcom G7
- Medtronic 780G + Guardian 4
- Omnipod 5 + Dexcom G7
- TIR improvement vs CSII alone
- Pediatric to adult coverage

Dual hormone (research):
- Insulin + glucagon
- Better hypoglycemia prevention

Monitoring:
- CGM standard: TIR > 70%, TBR < 4%
- HbA1c q3 mo
- Annual: lipid, retinopathy, nephropathy, foot, dental, mental health, vaccines

Education:
- DKA prevention (sick day rules)
- Hypoglycemia recognition
- Carb counting
- Sport/exercise adjustments

- GLP-1, SGLT2, DPP-4 䞍 routine
- GDM: insulin or metformin
- Preexisting T1DM/T2DM: pump + CGM ideal
- Tighter glucose: fasting < 95, 1 hr PP < 140, 2 hr < 120
- HbA1c < 6.5 if achievable safely
417.3.0.7.5 Geriatric
