Alcoholic Steatohepatitis (ASH, or AH) is a liver condition under Alcoholic Liver Disease (ALD), caused by chronic alcohol abuse. ASH is typically found in individuals with a history of heavy drinking for two or more decades, although there are examples of patients with ASH with history of less than 10 years of alcohol abuse.
Studies have shown that a dose-dependent relationship has been observed between alcohol intake and the risk of developing ALD. In fact, 90-100% of heavy drinkers suffer from steatosis and around 10 -35% are reported to have ASH. In the U.S. up to around 5 million people suffer from ASH, a disease that may be completely asymptomatic and therefore often remains undiagnosed.
