The effect of stress on liver function

«Psychosocial stress» is becoming an increasingly common concept in today’s complex and highly demanding society. Although the liver is one of the body’s most resilient organs, it is still vulnerable to the damaging effects of stress and aging, leading to liver disease, severe scarring and impaired function. Mental stress increases mortality from liver disease. Stressors activate macrophages and trigger an innate immune response, which then leads to the induction of inflammation and liver damage. In its diseases, symptoms such as low energy, fatigue, changes in employment status and functionality can also lead to the development of depression. The various physiological effects of glucocorticoids and catecholamines released into the bloodstream during stress lead to inflammation and oxidative stress in the liver. Research has explained the complex interactions that occur between stress system effectors and inflammation. Chronic psychological stress leads to an increase in serum glucocorticoid concentrations and the release of catecholamines, which increases the need for insulin. Insulin resistance leads to the development of metabolic-associated steatotic liver disease. The high prevalence of hepatogenic fatigue in chronic diffuse liver disease, its negative impact on the quality of life of patients, and the lack of effect of basic treatment lead to its aggravation due to stress. Sublingual S-adenosyl-L-methionine is effective in the treatment of hepatogenic stress fatigue, both in short-term and long-term use as part of the complex therapy of liver diseases.
