lifestyle
2

Weight reduction and physical activity

Structured exercise program combined with calorie restriction addresses insulin resistance underlying elevated C-peptide ratio, improving insulin sensitivity.

lifestyle
3

Low glycemic index dietary pattern

Carbohydrate modification emphasizing whole grains, legumes, and vegetables reduces postprandial glucose spikes and insulin demand.

dietary

Additional treatment options

Insulin-sensitizing pharmacotherapy

Metformin or other insulin-sensitizing agents reduce hepatic glucose production and improve peripheral insulin sensitivity.

medication

Structured resistance training program

Muscle-building exercise increases glucose uptake independent of insulin, addressing the underlying insulin resistance.
