Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent low-grade inflammation and a markedly increased risk of cardiovascular diseases (CVD). Leukocytes play an important role not only in host defense but are also increasingly recognized as key contributors to haemostasis and thromboinflammatory processes. In DM, chronic hyperglycaemia, oxidative stress and inflammation lead to leukocyte dysfunction, including enhanced cell activation, impaired mitochondrial function, and dysregulated interactions with platelets and endothelial cells. These alterations promote the thromboinflammatory state that contributes to vascular complications in DM. Thus, the modulation of oxidative stress and inflammation are important. Polyphenols are a class of plant secondary metabolites widely studied for their antioxidant and anti-inflammatory properties. This review comprehensively explores leukocyte dysfunction in DM, its contribution to thromboinflammation, and the mechanistic role of polyphenols in modulating these processes. The evidence presented suggests that polyphenols may contribute to the modulation of thromboinflammatory pathways. Further research in this area is required to enhance our understanding of thromboinflammation in DM and to translate these findings into effective adjunctive strategies, alongside standard pharmacological therapies to reduce CVD risk in individuals with DM.
