What is the recommended initial management approach for newly diagnosed type 2 diabetes in adults?
Initial management of type 2 diabetes centers on lifestyle intervention combined with metformin as first-line pharmacotherapy in most patients. Comprehensive lifestyle modifications including medical nutrition therapy, increased physical activity, and weight management are foundational. Treatment targets and medication selection should be individualized based on patient characteristics, comorbidities, and preferences.
