ADA Standards of Care in Diabetes — 2026

American Diabetes Association

Organ-protection-first approach to type 2 diabetes: choose therapy by cardiorenal profile, not by A1c alone, and integrate CGM and tirzepatide across the care spectrum.

What changed in this edition

  • GLP-1 RA or dual GIP/GLP-1 (tirzepatide) preferred second agent after metformin for most adults with T2D.
  • Tirzepatide endorsed for weight management and glycemic control; semaglutide 2.4 mg reaffirmed for obesity.
  • CGM recommended for all adults on insulin and for selected non-insulin-treated T2D with hypoglycemia risk.
  • A1c individualization band formally widened: <7% default, <6.5% if safe, <8% in frail/limited-life-expectancy.
  • Screening for MASH/steatotic liver disease with FIB-4 at least annually in T2D.
  • Finerenone integrated for CKD with albuminuria regardless of A1c.
  • Teplizumab reaffirmed for delaying stage 3 T1D in stage 2 relatives with dysglycemia.
  • Updated obesity-first framing: treat adiposity-based chronic disease as the driver of T2D.

Clinical takeaways

Pick therapy by comorbidity

ASCVD or high risk: GLP-1 RA with proven CV benefit or SGLT2i. Heart failure or CKD: SGLT2i. Obesity dominant: tirzepatide or semaglutide 2.4 mg. A1c not the first filter.

CGM deployment

All T1D; all T2D on any insulin; T2D without insulin if hypoglycemia risk, pregnancy, or motivation for lifestyle change. Target time-in-range 70–180 mg/dL >70%; time-below-range <4%.

Weight as a primary target

5–15% weight loss improves most T2D outcomes; ≥15% can induce remission in early T2D. Match intensity to BMI, comorbidity, and tolerability; metabolic surgery remains an option at BMI ≥30 with inadequate control.

Liver and kidney screening

FIB-4 annually; if indeterminate or high, proceed to elastography. Annual uACR and eGFR; start SGLT2i at eGFR ≥20 and finerenone per KDIGO criteria.

Hypoglycemia prevention

Review insulin and sulfonylurea regimens at every visit; de-intensify when A1c well below individualized target, especially in older adults. Structured glucagon access (including nasal/auto-injector).

Supporting trials

  • Tirzepatide outperformed insulin glargine for A1c and weight in T2D with high CV risk.

  • SURMOUNT-1PubMed 35658024

    Tirzepatide produced up to 22.5% weight loss in adults with obesity without diabetes.

  • Semaglutide 2.4 mg achieved 14.9% weight loss at 68 weeks.

  • Semaglutide reduced MACE by 20% in adults with obesity and established CVD without diabetes.

  • TN-10 / TeplizumabPubMed 31180194

    Teplizumab delayed progression to stage 3 T1D by a median of ~2 years.
