In this episode, Julia delves deep into the complex world of liver health, beginning with a foundational overview of liver physiology. She provides an in-depth look at how alcohol impacts liver function, breaking down the metabolism of ethanol & its detrimental effects. Julia then shifts the focus to understanding liver function tests & optimal enzyme levels, providing a detailed explanation of AST & ALT & elucidating why fluctuations in these levels may or may not be concerning. She provides a primer on the four major stages of liver disease, discussing risk & emphasizing the importance of early diagnosis. Julia highlights the role of liver disease in increasing the risk of cancer & cardiovascular disease & covers in detail the various strategies for diagnosing, treating, & preventing the progression of liver disease.
