If you have PCOS and have been told by your doctor that you have a fatty liver, you aren’t alone. Non-alcoholic fatty liver disease (NAFLD), commonly referred to as fatty liver, is highly prevalent in women with PCOS, affecting 15% to 55% of women depending on the diagnostic criteria used. NAFLD occurs as a result of excess triglycerides (fat) stored in the liver which causes inflammation and damage to liver cells. The liver isn’t meant to store fat; its role is to serve as the detox organ for the body filtering out harmful substances.

NAFLD is a silent condition. Most women with PCOS won’t know that they have it until getting blood results. Having fatty liver or NAFLD increases the risk of cardiovascular disease. If not treated, NAFLD can progress to more advanced stages of liver damage.

Diagnosing Fatty Liver

NAFLD can first be detected by checking levels of your liver function tests, or “LFTs” as the medical community has nicknamed them. LFTs are the liver enzymes alanine aminotransferase (ALT) or aspartate aminotransferase (AST) which become elevated when the liver is damaged. It’s important to know that most all medications pass through the liver and can also raise LFTs. This is why some physicians recommend an ultrasound of the liver or a liver biopsy to confirm a diagnosis of NAFLD.

Associated Factors Contributing to NAFLD in PCOS women:

• Excess abdominal weight
• Elevated androgens
• High triglycerides
• High LDL cholesterol level
• Low HDL cholesterol level
• High consumption of fat, sugar and refined foods
• Sedentary lifestyle
• Obstructive sleep apnea
• Genetics

Preliminary evidence suggests that high levels of androgens may also contribute to fat storage in the liver. While fatty liver disease is serious, it can easily be reversed and prevented with diet and lifestyle changes such as the ones listed below.

Following a Mediterranean style diet that is rich in olive oil and other monounsaturated fats may be beneficial to improve insulin, fight inflammation, and reduce liver fat. Not sure where to start?

Get Moving

A sedentary lifestyle is one of the contributing factors to NAFLD. Engaging in regular physical activity consisting of aerobic and resistance training, can decrease fatty liver even if weight loss isn’t achieved. Participants who engaged in 30 to 60 minutes of exercise two to three times each week saw significant reductions in liver fat. To make physical exercise a regular routine, prioritize it by scheduling it in your calendar. Performing in activities that are fun and enjoyable to do will also help increase your commitment.

Take Fish Oil

Omega-3 fatty acids like the ones found in cold water fish such as salmon, tuna and trout are effective at reducing triglycerides, inflammation, and insulin in women with PCOS. A study published in the Journal of Clinical Endocrinology and Metabolism showed that women with PCOS who supplemented their diets with 4 grams of fish oil for 8 weeks saw a significant decrease in liver fat and triglycerides. A fish oil supplement such as Nordic Naturals, is probably needed since it’s quite a challenge to eat enough fish to meet the therapeutic amounts of omega-3 fats.

Add a Probiotic

Emerging research is showing that unhealthy bacteria in our guts may contribute to fatty liver disease. Probiotics assist the body’s friendly bacteria to make it even more powerful. Friendly bacteria are important for proper maintenance of our immune system and for the digestion and absorption of food. One randomized controlled study showed that taking a probiotic (500 million CFUs) for three months improved LFTs in patients with NAFLD. For more information on probiotics, click here.

Consider Berberine

Berberine has been shown to be an effective option to reduce fatty liver. A review of 6 randomized control trials involving 500 individuals found that berberine significantly reduced fatty liver in those with non-alcoholic fatty liver disease (NAFLD).  Berberine lowered triglycerides and liver function enzymes, and overall improved liver condition. It has been found that berberine improves NAFLD by preventing liver fat build up and promoting fatty acid oxidation in skeletal muscle. For more information about berberine, see our article, 10 Benefits of Berberine for PCOS.

Supplement with Vitamin E and NAC

Women with PCOS have been shown to have higher levels of oxidative stress than women without PCOS. Oxidative stress is a contributing factor to diseases like NAFLD. Antioxidants work to fight oxidative stress and have been suggested in the treatment of NAFLD. Vitamin E, a powerful antioxidant is commonly recommended to those with NAFLD. Two randomized controlled trials showed significant improvements in fatty liver in individuals who supplemented their diets with 800 to 1,000 IU/day of vitamin E. No studies have specifically looked at the benefits of vitamin E in women with PCOS. Treatment with high doses of vitamin E should be monitored with caution as it can be stored in fat and become toxic.

N-acetylcysteine (NAC) is another antioxidant that has been shown to be effective at reducing oxidative stress in women with PCOS as well as treat NAFLD. Patients who were treated with NAC (1200 mg/daily) for 3 months showed a significant improvement in LFTs.

Don’t Forget the Choline!

Also be sure to get in adequate amounts of choline. Choline plays an essential role in liver health. A deficiency of choline is associated with higher rates of fatty liver. Most people don’t meet choline requirements. Not sure if you’re getting enough? Check out this article, Don’t Forget the Choline!

Take Milk Thistle

Silybum marianum, commonly known as milk thistle, is an herb native of the Mediterranean and North African regions that is used in the treatment of liver diseases. Some studies have suggested that the active extract of milk thistle possesses antioxidant, anti-inflammatory and anti-fibrotic properties. In a randomized study, Hajaghamohammadi et al showed that milk thistle (140 mg/day) for 2 months decreased LFTs significantly more than metformin in individuals with NAFLD.

Milk thistle has also been shown to help with insulin resistance. In another randomized trial, patients with NAFLD who took a combination of milk thistle and vitamin E for 12 months (200 mg/day) showed improvements in liver enzymes and insulin resistance. Velussi et al showed that treatment with milk thistle for 12 months (600 mg/day) was associated with a reduction of insulin resistance and a significant decrease in fasting insulin levels in people with diabetes.

Non-alcoholic fatty liver disease (NAFLD) in women with PCOS is common and serious, but can easily be reversed with diet and lifestyle changes.
