The increasing overlap between metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes (T2D) presents a significant public health challenge, demanding earlier detection and more integrated care strategies. These two conditions, both highly prevalent and rapidly increasing worldwide, are intricately linked, amplifying each other’s progression and increasing the risk of serious complications. Effective management requires a holistic approach, addressing both the metabolic and liver-specific aspects of the disease.
MASLD, formerly known as nonalcoholic fatty liver disease (NAFLD), is now understood to be closely tied to metabolic dysfunction, although T2D is characterized by the body’s inability to effectively use insulin. The bidirectional influence between these conditions means that diabetes can accelerate the progression from steatosis (fat accumulation in the liver) to fibrosis (scarring), and MASLD can worsen insulin resistance, inflammation, and the risk of cardiovascular disease. This complex interplay necessitates a shift towards proactive screening and coordinated treatment plans.
The Intertwined Pathophysiology of MASLD and T2D
Research highlights a strong connection between MASLD and T2D, with MASLD associated with a 2.2-fold increased risk of developing diabetes, according to a study by Mantovani et al. In Gut (2021) . The presence of both conditions significantly elevates the risk of both hepatic and extrahepatic complications. Specifically, MASLD-related liver fibrosis is a major driver of liver disease progression and is linked to increased risk of cardiovascular and renal diseases in individuals with T2D .
Experts convened by the French Association for the Study of the Liver (AFEF) and the Francophone Diabetes Society (SFD) have emphasized the importance of systematic screening for advanced fibrosis related to MASLD in patients with T2D, given its high prevalence and the availability of specific therapeutic interventions . This proactive approach aims to identify individuals who would benefit most from targeted treatment to unhurried disease progression and reduce the risk of associated clinical events.
Optimizing Management Strategies
Effective management of patients with both T2D and MASLD requires a multifaceted approach encompassing dietary and behavioral changes, pharmacological treatment of T2D, and, in some cases, bariatric procedures. Dietary interventions and lifestyle modifications are cornerstones of treatment, focusing on weight management, healthy eating habits, and regular physical activity.
The interplay between glycemic control and cirrhosis management is particularly noteworthy. Improving one often positively impacts the other, highlighting the synergistic benefits of integrated care . The longer an individual lives with T2D, the greater the likelihood of developing or experiencing progression of MASLD, underscoring the importance of proactive diabetes management in preventing liver complications .
Adapting drug therapy in the presence of significant fibrosis is crucial to slowing liver disease progression. Healthcare professionals, particularly diabetologists and primary care physicians, need guidance on optimizing pharmacological treatment strategies for patients with both conditions. Bariatric procedures may also be considered in certain cases of MASLD.
Looking Ahead
The growing recognition of the MASLD-T2D overlap is driving a need for improved diagnostic tools, standardized screening protocols, and collaborative care models. Further research is essential to refine treatment strategies and identify novel therapeutic targets. The focus will likely remain on early detection, integrated management, and personalized approaches to mitigate the combined burden of these increasingly prevalent metabolic disorders.
