Elevated Circulating C Peptide Concentration C4280763
This test measures elevated C-peptide, a substance produced alongside insulin. High levels indicate the body is making insulin, which may occur with insulin resistance or other conditions.

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Endocrine management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Low glycemic index diet
Implementation of dietary practices focusing on low glycemic index foods to minimize insulin spikes and reduce C-peptide levels. This includes selecting whole grains, legumes, and non-starchy vegetables over refined carbohydrates.
Weight management and body composition improvement
Structured program targeting reduction of abdominal adiposity through combined dietary modification and increased physical activity. Weight loss improves insulin sensitivity and can lower elevated C-peptide concentrations.
Additional treatment options
Insulin sensitizer therapy
Pharmacological treatment with insulin-sensitizing agents when indicated to improve cellular response to insulin and reduce compensatory hyperinsulinemia reflected in C-peptide levels. Must be prescribed and monitored by healthcare provider.
medicationMetabolic parameter surveillance
Regular monitoring of fasting glucose, HbA1c, C-peptide, and related metabolic markers to assess insulin sensitivity and guide treatment decisions over time.
monitoringChromium supplementation
Adjunctive supplementation with chromium, a trace mineral involved in glucose metabolism, may support insulin sensitivity as part of a comprehensive management approach.
