- Alcohol-related liver disease and alcohol-induced liver damage
- Alcoholic Liver Disease (ALD) describes liver problems linked to excessive alcohol intake.
- Alcohol abuse severely stresses the liver, one of the body’s main filtering organs.
- Alcohol triggers hormonal and metabolic changes that alter liver lipid processing.
- Epinephrine stimulates pancreatic glucagon release; together they stimulate glycogenolysis in liver cells.
- Epinephrine stimulates triglyceride and glycerol breakdown, releasing free fatty acids into the bloodstream and liver.
- Some lipids are stored in liver cells, while the remainder are converted into very low density lipoprotein (VLDL).
- Accumulation of stored triglycerides and VLDL causes fatty liver, also called hepatic steatosis.
- More alcohol produces and stores more lipids, and these effects accumulate over time.
- Fat accumulation can impair normal liver function.
- ALD can progress from fatty liver to more severe liver disease, and different forms can occur at the same time.
- The three most common forms of ALD are fatty liver, alcoholic hepatitis, and cirrhosis.
- Fatty liver is usually benign and reversible when alcohol use is controlled, but it can progress to more fatal diseases.
- Alcoholic hepatitis causes liver inflammation with symptoms such as swelling, abdominal pain, nausea, fever, jaundice, and vomiting.
- Excessive alcohol destroys liver cells; inflammation, scarring, and regenerative nodules can produce cirrhosis.
- Cirrhosis blocks blood flow and causes wastes and toxins to build up in the body.
- Cirrhosis cannot strictly be cured, but medical treatment, stopping alcohol use, and complication management can halt or control it.
- Cirrhosis symptoms include ascites, abdominal pain, fever, thirst, confusion, and fatigue.
- According to the CDC, 14,406 Americans died from alcohol-related liver diseases in 2007.
- Not every heavy drinker develops or dies from liver disease, and cirrhosis is not always caused by alcoholism.
