Natural Recovery by the Liver and Other Organs After Chronic Alcohol Use

Introduction

A vast body of evidence from human studies and animal research clearly indicates that chronic, heavy alcohol consumption causes structural damage and/or disrupts normal organ function in virtually every tissue of the body. In heavy consumers of alcohol, the liver is especially susceptible to alcohol-induced injury.1,2 Additionally, several other organs—including the gastrointestinal...

Alcoholic Liver Disease: Pathogenesis and Current Management

Excessive alcohol consumption is a global healthcare problem. The liver sustains the greatest degree of tissue injury by heavy drinking because it is the primary site of ethanol metabolism. Chronic and excessive alcohol consumption produces a wide spectrum of hepatic lesions, the most characteristic of which are steatosis, hepatitis, and fibrosis/cirrhosis. Steatosis is the earliest response to...

Clinical Laboratory Stressors Used to Study Alcohol–Stress Relationships

A comprehensive understanding of the relationship between stress and alcohol use is important for understanding the risks of developing alcohol problems and subsequent relapse. Although the relationship is complex, substantial evidence supports that exposure to chronic stress early in life (e.g., Sher et al. 1997), adult trauma (Kessler et al. 1995), and the presence of anxiety disorders (Grant et...

In Utero Alcohol Exposure, Epigenetic Changes, and Their Consequences

Alcohol exposure of the developing embryo and fetus in utero can have a wide range of detrimental effects collectively referred to as fetal alcohol spectrum disorders (FASD). Researchers are intensively investigating the mechanisms that may contribute to alcohol’s effects on the developing organism and to the resulting consequences, particularly with respect to the cognitive and behavioral...

The Gastrointestinal Microbiome: Alcohol Effects on the Composition of Intestinal Microbiota

It has been estimated that approximately 2 billion people worldwide drink alcohol on a daily basis, with more than 70 million people having a diagnosed alcohol use disorder (World Health Organization 2004). Globally, alcohol use is the fifth leading risk factor for premature death and disability among people between the ages of 15 and 49 (Lim et al. 2012). Excessive alcohol consumption in the...
