Abstract

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease with a continually rising global prevalence and significant mortality rates. Emerging evidence suggests a strong association between MASLD and mental health disorders such as depression and anxiety. In addition to the shared risk factors such as obesity, type 2 diabetes and insulin resistance which contribute to this relationship through mechanisms involving systemic inflammation and oxidative stress; other pathophysiological mechanisms such as dysregulation of hypothalamic-pituitary-adrenal axis, neurotransmitter imbalances and gut dysbiosis have also been proposed to play a significant role. The current paper aims to review the pathophysiological mechanisms underlying the association between MASLD and mood disorders such as depression and anxiety. We note a bidirectional relationship between these two disorders, and the dual burden of both these disease processes can be alleviated by early detection and encouraging a more proactive and holistic approach through diet and lifestyle changes. This review summarizes the existing literature on association between MASLD and depression.

Core Tip: Metabolic dysfunction-associated steatotic liver disease is associated with mood disorders such as depression and anxiety through shared pathophysiological pathways. This review links systemic inflammation, hypothalamic-pituitary-adrenal axis dysregulation, gut dysbiosis, and neurotransmitter imbalances as mediators of this bidirectional relationship. We highlight how overlapping risk factors such as insulin resistance, obesity, sarcopenia, poor sleep, and physical inactivity exacerbate both the disease processes. Recognizing the mental health burden allows for improved patient outcomes and supports a holistic, lifestyle-focused treatment model that addresses both physical and mental health.
