Hepatic steatosis, more commonly called fatty liver, refers to conditions that involve a buildup of fats in the liver, such as:
- Nonalcoholic fatty liver disease (NAFLD) is not caused by consumption of alcohol
- Nonalcoholic fatty liver (NAFL): there is fat buildup in the liver, but it is not inflamed
- Nonalcoholic steatohepatitis (NASH): there is fat buildup in the liver, and it is inflamed
- Alcohol-related fatty liver disease is caused by excessive consumption of alcohol
Nonalcoholic hepatic steatosis is treated by addressing medical conditions that are often associated with NASH:
- Weight loss in patients who are overweight or obese
- `Hepatic steatosis may be cured if patients have a sustained weight loss of 10% of their body weight
- Consume a healthy diet
- Exercise regularly
- `Hepatic steatosis may be cured if patients have a sustained weight loss of 10% of their body weight
- Manage blood sugar in patients who have diabetes
- Don’t smoke
- Avoid alcohol, which can stress the liver

Alcohol-related hepatic steatosis is treated with:
- Abstinence from alcohol
- Nutrition therapy
- Medications to help reduce liver inflammation
- Steroid treatment with prednisolone is usually the first-line medication
- Pentoxifylline, if steroids don’t work
- Liver transplant for patients with advanced alcoholic cirrhosis
