A cross-sectional study observing overweight and obese children with non-alcoholic fatty liver disease has found that vitamin D levels may be associated with the severity of the disease.
The study, published in European Journal of Endocrinology, found an association between vitamin D levels and the presence of nonalcoholic steatohepatitis and liver fibrosis in patients with non-alcoholic fatty liver disease.
Non-alcoholic fatty liver disease (NAFLD) is caused by fat being deposited into the liver not due to excessive alcohol use. Non-alcoholic steatohepatitis (NASH) is the most extreme form of non-alcoholic fatty liver disease. Fibrosis is the formation of excess connective tissue that damages the function of the tissue or organ it is formed in. Scarring is a form of fibrosis that occurs in response to injury.
