Objectives of Study: |
Primary Objective: To evaluate the effect of ω-3 polyunsaturated fatty acids on pancreatic β-cell function in patients with type 2 diabetes under conventional treatment. Secondary Objectives: To assess the impact of ω-3 polyunsaturated fatty acids on glycemic control, insulin secretion, insulin sensitivity, body weight, body fat content, waist circumference, lipid profile, blood pressure, hepatic fat content, and other metabolic parameters under conventional treatment. Exploratory Objectives: To investigate the potential effects of ω-3 polyunsaturated fatty acids on the incidence and progression risk of new-onset diabetes complications in patients with type 2 diabetes under conventional treatment. |
