From the Guidelines
The current approach to diabetes management prioritizes individualized care, focusing on patient characteristics, comorbidities, and preferences, with metformin as the preferred initial pharmacologic agent for type 2 diabetes, alongside lifestyle modifications. For type 2 diabetes, the initial therapy typically includes metformin (starting at 500mg daily, increasing to 1000mg twice daily as tolerated) alongside lifestyle modifications such as dietary changes, regular physical activity (150 minutes weekly), and weight management 1. If glycemic targets aren't achieved with metformin alone, second-line options depend on patient-specific factors, including the presence of established cardiovascular disease or high risk, where GLP-1 receptor agonists or SGLT-2 inhibitors are preferred 1. For those with heart failure or chronic kidney disease, SGLT-2 inhibitors are particularly beneficial. Other medication classes include DPP-4 inhibitors, sulfonylureas, thiazolidinediones, and insulin therapy. For type 1 diabetes, multiple daily insulin injections or insulin pump therapy remains the cornerstone of treatment, with a focus on matching prandial insulin doses to carbohydrate intake, preprandial blood glucose levels, and anticipated activity level 1. Regular monitoring of blood glucose levels is essential, with HbA1c targets generally between 7% and 8% for most adults, as recommended by the American College of Physicians 1. Comprehensive diabetes care also includes regular screening for complications (retinopathy, nephropathy, neuropathy), cardiovascular risk assessment, and addressing comorbid conditions like hypertension and dyslipidemia. This multifaceted approach addresses not only glucose control but also cardiovascular risk reduction and prevention of diabetes-related complications. Key considerations in diabetes management include:
- Personalizing goals for glycemic control based on patient characteristics, comorbidities, and preferences 1
- Considering deintensifying pharmacologic therapy in patients who achieve HbA1c levels less than 6.5% to minimize harms and treatment burden 1
- Focusing on minimizing symptoms related to hyperglycemia in patients with limited life expectancy or significant comorbid conditions, rather than targeting a specific HbA1c level 1

From the Research
Approach to Diabetes Management
The approach to diabetes management involves a combination of lifestyle modifications and pharmacological interventions. According to 2, lifestyle modifications such as diet and exercise can help achieve better management of diabetes by governing the complex interplay between genetics and environmental factors that contribute to the development of type 2 diabetes.
Lifestyle Modifications
- Diet: A healthy diet that is low in sugar and saturated fats can help manage blood sugar levels 2
- Exercise: Regular physical activity can improve insulin sensitivity and reduce the risk of cardiovascular disease 2
Pharmacological Interventions
- Metformin: First-line treatment for type 2 diabetes, especially for patients with a high risk of cardiovascular disease 3, 4, 5, 6
- SGLT-2 inhibitors: Effective in reducing mortality, cardiovascular, and renal outcomes in patients with type 2 diabetes, especially those with established cardiovascular disease or kidney disease 3, 5, 6
- GLP-1 receptor agonists: Beneficial effects on mortality and major cardiovascular adverse events, especially in patients with established cardiovascular disease 3, 6
- DPP-4 inhibitors: Weight-neutral and have few adverse effects, but may not be as effective as SGLT-2 inhibitors in reducing cardiovascular and renal outcomes 3, 5
Treatment Guidelines
- The American Association of Clinical Endocrinologists and the American Diabetes Association recommend an initial approach consisting of lifestyle changes and monotherapy, preferably with metformin 4, 6
- Treatment choices should be guided by glycemic efficacy, safety profiles, patient comorbidities, route of administration, patient preference, and cost 6
- Consideration of empagliflozin or liraglutide for patients with suboptimally controlled long-standing type 2 diabetes and established atherosclerotic cardiovascular disease, as these agents have been shown to reduce cardiovascular and all-cause mortality 6
