Alcohol Consumption and Diabetes: Differential Impacts on Type 1 and Type 2 Diabetes Mellitus

Alcohol consumption has complex effects on glucose metabolism, insulin sensitivity, and overall diabetes management. While moderate alcohol intake has been associated with potential benefits in insulin sensitivity, excessive consumption exacerbates glycemic control and increases the risk of diabetes-related complications. This review examines the differential impacts of alcohol on Type 1 and Type 2 diabetes, focusing on pathophysiology, clinical outcomes, and management strategies. The discussion integrates recent studies on alcohol metabolism, its endocrine effects, and epidemiological evidence linking alcohol consumption patterns to diabetes incidence and progression.
