Immediate Therapeutic Approach

The American Diabetes Association recommends initiating metformin at diagnosis unless contraindicated, as this is the cornerstone of type 2 diabetes management in older adults 1, 2
The American Geriatrics Society suggests verifying renal function is adequate before starting metformin, with serum creatinine must be <1.5 mg/dL in men or <1.4 mg/dL in women 3
The American Diabetes Association recommends measuring serum creatinine at least annually and with any dose increase to monitor for lactic acidosis risk 3

The American Geriatrics Society recommends a target HbA1c of <7.0% for relatively healthy 65-year-old patients, as this reduces microvascular complications without excessive hypoglycemia risk 3, 4

The American Heart Association recommends limiting sodium intake to <2,300 mg/day to reduce polyuria and improve cardiovascular health 1
The American Diabetes Association suggests avoiding sugar-sweetened beverages entirely to improve glycemic control and reduce osmotic load 5
The American Diabetes Association recommends engaging in ≥150 minutes per week of moderate-to-vigorous aerobic activity, spread over at least 3 days with no more than 2 consecutive days without activity 1

The American Diabetes Association recommends self-monitoring blood glucose to assess response to metformin and guide dose titration 6
The American Diabetes Association suggests rechecking HbA1c at 3 months; if target not achieved, add second agent 2

The American Diabetes Association recommends adding basal insulin if HbA1c ≥9.0%, as this provides the most robust glucose lowering 2
The American Diabetes Association suggests adding a GLP-1 receptor agonist for additional weight loss benefit and cardiovascular protection 2
The American Geriatrics Society recommends avoiding sulfonylurea in older adults due to prolonged half-life and hypoglycemia risk, unless cost is prohibitive 3
