Experts aren\u2019t sure why some people accumulate fat in the liver while others do not, but they all agree it\u2019s a serious health issue.\n\nOne type, known as nonalcoholic fatty liver disease \u2014 or NAFLD \u2014 is a collection of liver conditions affecting people who drink little to no alcohol. It\u2019s also the most common form of chronic liver disease and is tied closely to diabetes.\n\nIn episode 21 of TGen Talks, Johanna DiStefano, Ph.D., a Professor in TGen\u2019s Quantitative Medicine and Systems Biology Division and Head of its Diabetes and Fibrotic Disease Unit discusses the connections between NAFLD and diabetes, her work to determine the disease trajectory of patients with NAFLD, and what you can do to avoid getting NAFLD.
