From the Guidelines
An uncommon reason for fatty liver in a young woman is polycystic ovary syndrome (PCOS), as it can lead to non-alcoholic fatty liver disease (NAFLD) due to insulin resistance and hormonal imbalances that affect fat metabolism in the liver. This is supported by the study 1, which lists polycystic ovary syndrome as an independent risk factor for the presence of NAFLD.
Key Points to Consider
- Other less common causes of fatty liver in young women include:
- Wilson's disease (copper accumulation)
- Autoimmune hepatitis
- Medications like tamoxifen or corticosteroids
- Rapid weight loss
- Certain genetic disorders like hypobetalipoproteinemia
- Pregnancy-related conditions such as HELLP syndrome or acute fatty liver of pregnancy
- The study 1 also highlights that patients with simple steatosis have very slow, if any, histological progression, while patients with NASH can exhibit histological progression to cirrhotic-stage disease.
Diagnosis and Treatment
- Comprehensive testing including liver function tests, hormone panels, copper studies, autoimmune markers, and possibly liver biopsy may be needed to diagnose the underlying cause of fatty liver.
- Treatment depends on the underlying cause but often includes lifestyle modifications, specific medications for the primary condition, and monitoring of liver function, as noted in the guideline 1.
Importance of Early Identification
- Early identification of these uncommon causes is crucial as they may require different management approaches than typical fatty liver disease, and can help improve morbidity, mortality, and quality of life outcomes.

From the Research
Uncommon Reasons for Fatty Liver in Young Women
- An uncommon reason for fatty liver in a young woman is the use of tamoxifen, a medication commonly used to treat breast cancer 2.
- Long-term use of tamoxifen has been shown to significantly aggravate fatty liver status compared to other treatment modalities in breast cancer patients 2.
- The development of fatty liver due to tamoxifen use is a concern, as it can lead to worsening of liver function and potentially increase the risk of other metabolic diseases.
Polycystic Ovary Syndrome (PCOS) and Fatty Liver
- PCOS is a common endocrine disorder in reproductive-aged women, and it has been linked to an increased risk of nonalcoholic fatty liver disease (NAFLD) 3, 4, 5, 6.
- Insulin resistance and hyperandrogenemia are potential links between PCOS and NAFLD 5, 6.
- Women with PCOS should be screened for NAFLD, particularly those with other metabolic risk factors, and lifestyle interventions and weight loss are recommended as first-line treatment 5, 6.
