NASH – US 2015 NASH – US 2030
Non-alcoholic steatohepatitis (NASH) predicted to become the leading cause of liver transplant and liver cancer
Underdiagnosed today due to need for confirmatory invasive biopsy
Diagnosis rate expected to grow with availability of treatment and non-invasive Dx (e.g. Fibroscan)
