The Short Answer: Fatty liver in people with autoimmune conditions develops from excess sugar and carbohydrates, not from eating dietary fat. When the liver processes too many carbs and fructose, it produces excess fat that accumulates in liver cells. Managing blood sugar and treating the underlying autoimmune condition are the keys to reversing fatty liver before it progresses to a more serious disease.

Understanding Fatty Liver in Autoimmune Disease

If you have an autoimmune condition and struggle with excess weight or high blood sugar, your blood tests may show fatty liver (elevated liver enzymes). Although fatty liver has no obvious symptoms, a fatty liver hinders detoxification, promotes inflammation, may increase the risk of gallstones, and increases the risk of heart attack. So a fatty liver means eat less fat, right? Wrong. The culprit in fatty liver isn’t too much fat but rather too many sugars and carbohydrates.

Too many carbs are the main culprits behind the excess belly fat that signals the development of fatty liver. This is because sugar signals the liver to produce more fat.

This process is heightened when the liver must process fructose, particularly high-fructose corn syrup found in soft drinks and other ultra-processed foods. For people with autoimmune conditions like Hashimoto’s low thyroid, this metabolic stress compounds existing immune dysregulation and inflammation.

Unmanaged autoimmune disease itself also contributes to fatty liver disease. Research suggests a strong link between autoimmune-driven thyroid dysfunction and fatty liver disease, since proper thyroid and immune function are vital to fat metabolism and blood sugar regulation.

How Fatty Liver Progresses in Autoimmune Patients

While some liver fat is normal, if it exceeds 5 to 10 percent of the organ’s total weight, it’s considered fatty liver and represents the first stage of non-alcoholic fatty liver disease (NAFLD). If fatty liver progresses unchecked, it can advance all the way to cirrhosis.

(Alcohol abuse can also cause fatty liver disease, and most people with alcohol use disorder develop a fatty liver.)

NAFLD is the most common liver disorder in the West, affecting as many as one-third of Americans. It primarily affects those who are overweight and middle-aged, but NAFLD increasingly affects children and teens due to overconsumption of sodas, sweets, and high-carb foods. High cholesterol and diabetes typically accompany NAFLD as well.

Autoimmune patients, particularly those with Hashimoto’s low thyroid, face an elevated risk for NAFLD because autoimmune dysfunction disrupts fat metabolism and liver function. This is why managing the underlying autoimmune condition goes far beyond taking medication alone.

Reversing Fatty Liver: A Functional Medicine Approach

The good news is you can reverse fatty liver before serious complications develop. Even though the liver may not initially signal distress with symptoms, it’s important to take liver health seriously to prevent long-term damage. Steps to reverse fatty liver include:

Manage your autoimmune condition with functional medicine. A cornerstone of treatment is addressing the autoimmune dysfunction driving metabolic imbalance. In conditions like Hashimoto’s low thyroid, medication alone may not resolve the mechanisms that promote fatty liver. At RedRiver, we work to identify and treat the root causes of immune dysregulation. Follow the recommendations below alongside professional guidance.

Adopt a lower-carb, sugar-free diet. High blood sugar directly leads to fatty liver accumulation. To reverse it, bring blood sugar down to healthy levels with a whole-foods diet abundant in fibrous vegetables, healthy fats, and proteins, while avoiding foods that spike blood sugar. Most people also begin to lose excess fat on this approach, further unburdening the liver.

Exercise daily. Regular physical activity helps lower blood sugar, detoxify the body, and shed excess fat, all of which reverse fatty liver progression.

Avoid alcohol and unnecessary medications. Alcohol is very hard on the liver, as are many medications. Avoid both as much as possible while reversing fatty liver.

Lower inflammation. The liver plays a critical role in managing systemic inflammation, and lowering overall inflammation eases its burden. The most important ways to do this are to remove inflammatory foods (gluten and dairy are the most common) and minimize exposure to toxins and chemicals.

Take natural anti-inflammatory compounds. Certain nutritional compounds effectively lower inflammation and support liver recovery. These include high doses of emulsified turmeric and resveratrol, as well as absorbable forms of glutathione, vitamin D, and other targeted compounds. Our doctors at RedRiver can recommend appropriate dosing and combinations.

Support liver detoxification pathways. When liver cells are clogged with fat, everyday detoxification becomes impaired. The liver responds well to herbs and compounds that support detoxification, such as milk thistle or N-acetyl-cysteine.
