Stress generally refers to a state of mind or mental tension that is linked to anxiety, irritability, insecurity, mental disorders like depression or insomnia and physical ones like migraine, cardiovascular ailments and sexual dysfunction. It occurs in the presence of an external stimulus called the stressor. Usually factors like work pressure, personal commitments and working environment act as common stressors in daily life.

The study took into account factors such as alcohol consumption, obesity, diabetes and socio-economic status. Reasons for this are unclear as the biological links between psychological distress and liver disease are not well understood so far, the researchers said. Previous research suggests mental distress can put people at increased risk of cardiovascular disease. At the same time, risk factors for cardiovascular disease - such as obesity and raised blood pressure - have been linked to a common form of liver disease, known as non-alcoholic fatty liver disease. In a similar way, suffering from anxiety and depression may be indirectly linked to an increased risk of death from liver disease, the authors wrote. (Read: Stressed & depressed?
