Can fatty liver be cured completely?

Fatty liver disease, also known as hepatic steatosis, is a condition where excess fat accumulates in the liver. It’s estimated that up to 30% of adults in developed countries have fatty liver disease. The good news is that yes, fatty liver can often be cured completely with the right treatment plan.

What causes fatty liver disease?

There are two main types of fatty liver disease:

  • Nonalcoholic fatty liver disease (NAFLD)
  • Alcoholic liver disease (ALD)

As the names suggest, NAFLD occurs in people who drink little to no alcohol, while ALD is caused by excessive alcohol consumption. The specific causes of NAFLD are not fully understood, but it’s strongly associated with obesity, insulin resistance, high blood lipids, and metabolic syndrome. Genetic factors can also play a role. ALD is directly caused by regularly consuming more than the recommended limits of alcohol.

What are the stages of fatty liver disease?

There are generally considered to be four stages of fatty liver disease:

  1. Simple fatty liver – fat accumulation in the liver with no inflammation or liver damage.
  2. Non-alcoholic steatohepatitis (NASH) – fat accumulation plus inflammation that can lead to scar tissue.
  3. Fibrosis – extensive scar tissue begins replacing healthy liver tissue.
  4. Cirrhosis – severe scarring that permanently damages the liver.

Not everyone with fatty liver will progress through all the stages. Simple fatty liver and NASH are considered reversible if caught early and managed properly. Once significant fibrosis or cirrhosis develops, damage is harder to reverse.

What are the symptoms of fatty liver disease?

In the early stages, fatty liver disease usually has no obvious symptoms. As it progresses, possible symptoms include:

  • Fatigue and weakness
  • Abdominal discomfort
  • Enlarged liver
  • Jaundice (yellow skin)
  • Spider-like blood vessels under the skin
  • Itching
  • Fluid accumulation in the abdomen and legs
  • Confusion and impaired brain function

However, many people remain asymptomatic until irreversible liver damage occurs. That’s why early screening is recommended for at-risk individuals.

What are the risk factors for fatty liver disease?

The main risk factors include:

  • Obesity or being overweight
  • Insulin resistance and type 2 diabetes
  • High blood lipids (cholesterol and triglycerides)
  • Metabolic syndrome
  • Rapid weight loss
  • Certain medications (e.g. steroids, tamoxifen)
  • Chronic hepatitis C infection
  • Excessive alcohol consumption
  • Malnutrition
  • Genetic predisposition

How is fatty liver disease diagnosed?

If fatty liver disease is suspected based on risk factors and symptoms, doctors can use several tests to confirm the diagnosis:

  • Blood tests: Liver enzymes (ALT, AST) and liver function tests are elevated.
  • Imaging: Ultrasound, MRI, CT scan show fat buildup in the liver.
  • Liver biopsy: Examining a small sample of liver tissue can confirm fatty liver and assess the degree of scarring.

Transient elastography (FibroScan) and fibrotest are two newer non-invasive methods of assessing liver fibrosis.

Can you reverse fatty liver disease naturally?

In the early stages of fatty liver disease, natural lifestyle changes can help reverse fat accumulation and inflammation in the liver. Key strategies include:

  • Losing weight – Reducing body and liver fat is crucial. Aim to lose 5-10% of body weight gradually.
  • Following a liver-friendly diet – Choose Mediterranean style diets with healthy fats. Avoid sugar and refined carbs.
  • Cutting out alcohol – Alcohol is directly toxic to the liver.
  • Increasing physical activity – Moderate exercise for at least 150 minutes per week aids weight loss.
  • Managing related conditions – Optimize control of diabetes, high cholesterol, high blood pressure.

Studies show these natural interventions can resolve fatty liver in up to 40% of patients. However, natural reversal becomes less likely once fibrosis sets in.

What medications treat fatty liver disease?

While no medications are FDA approved specifically for fatty liver, some medications can help by targeting different disease pathways:

Medication Mechanism
Vitamin E Powerful antioxidant that reduces oxidative stress and liver inflammation
Pioglitazone Insulin sensitizer that helps resolve NASH
GLP-1 agonists Diabetes medications that improve insulin resistance and promote weight loss
Statins Lower cholesterol and may decrease liver inflammation
Pentoxifylline Reduces TNF alpha and other inflammatory cytokines
Ursodeoxycholic acid Anti-inflammatory and improves bile flow

However, most medications only help a subset of patients and do not reverse late stage fibrosis and cirrhosis.

Can bariatric surgery reverse fatty liver disease?

Weight loss surgery such as gastric bypass and sleeve gastrectomy can produce rapid, significant weight loss and improvement in metabolic factors. Studies consistently show bariatric surgery leads to the following liver benefits:

  • Decreased fat content and liver enzymes
  • Reduced inflammation and oxidative stress
  • Regression of fibrosis in most patients
  • Over 90% reversal of NASH

Both restrictive procedures (gastric banding) and malabsorptive procedures (bypass) improve fatty liver, with the latter having greater efficacy. However, a multidisciplinary approach with diet and lifestyle changes post-surgery is still important.

What foods help reverse fatty liver?

Diet is one of the most crucial components in resolving fatty liver naturally. Follow these liver-friendly nutrition tips:

  • Increase healthy fats – Nuts, olive oil, avocado, salmon. Omega-3s help reduce liver fat.
  • Eat more fiber – Fruits, vegetables, whole grains, legumes.
  • Choose plant-based proteins – Lentils, beans, tofu.
  • Avoid added fructose and high fructose corn syrup.
  • Cut down on saturated fats – Red meat, butter, cheese.
  • Reduce or eliminate alcohol.
  • Drink green tea and coffee.

A Mediterranean diet or slightly modified low-carb diet have the most evidence for improving NAFLD.

What supplements help reverse fatty liver?

Certain supplements can provide additional benefit alongside diet and lifestyle changes:

  • Vitamin E: Up to 800 IU/day significantly improves NASH.
  • Milk thistle: Silymarin has antioxidant and anti-inflammatory effects.
  • Berberine: This plant extract reduces liver fat and increases insulin sensitivity.
  • Astaxanthin: A potent antioxidant that may decrease fibrosis.
  • Probiotics: Can help reduce NAFLD severity and symptoms.

Always consult your doctor before starting any new supplement, especially with liver conditions.

When should you see a doctor for fatty liver?

It’s important to consult a hepatologist (liver specialist) if you have:

  • Known risk factors for fatty liver
  • Elevated liver enzymes or abnormal liver function
  • Moderate to severe fibrosis diagnosed through elastography
  • Symptoms suggesting advanced liver disease
  • Coexisting liver conditions like hepatitis B or C

Early specialist intervention and monitoring can help prevent progression to cirrhosis. Your doctor may prescribe medications and order tests to assess fibrosis.

What are the complications of fatty liver disease?

Potential complications of untreated progressive fatty liver disease include:

  • Cirrhosis – Scar tissue replaces healthy liver tissue, causing liver failure.
  • Liver cancer – People with cirrhosis have a higher risk of liver cancer.
  • Gallstones – Rapid weight loss and insulin resistance increase gallstone risk.
  • Enlarged spleen – Advanced cirrhosis causes increased spleen size.
  • Bleeding disorders – Impaired liver function affects blood clotting.
  • Hepatic encephalopathy – Confusion and altered brain function due to liver failure.
  • Fluid retention – Cirrhosis causes leakage of fluid into the abdomen and legs.

That’s why early diagnosis and prompt treatment of fatty liver are critical before these serious complications occur.

What’s the best diet for nonalcoholic fatty liver disease?

The most effective diet for treating NAFLD includes:

  • Lowering overall calorie intake to promote weight loss if overweight.
  • Limiting carbohydrate intake to 40-50% of total calories.
  • Choosing healthy unsaturated fats like olive oil and avocados.
  • Increasing intake of anti-inflammatory foods like oily fish, nuts, fruits, vegetables.
  • Eliminating added sugars, refined grains, and processed foods.
  • Restricting saturated fats to less than 10% of calories.
  • Adequate protein intake to prevent muscle loss when losing weight.

Many patients find a Mediterranean style diet best meets these goals. Intermittent fasting may provide an additional benefit by improving insulin sensitivity.

What foods should you avoid with fatty liver?

It’s important to avoid foods that are high in sugar, refined carbohydrates, unhealthy fats, and calories. Foods to limit or avoid include:

  • Added sugars – soda, candy, baked goods
  • Refined grains – white bread, pasta, rice
  • Fried foods and trans fats
  • Processed meats – bacon, sausage, deli meats
  • Full fat dairy – cheese, ice cream, sour cream
  • Packaged snacks – chips, crackers, cookies
  • Sweetened beverages – juices, sports drinks
  • Fast food and takeout
  • Alcohol

Read nutrition labels closely and beware of foods containing high fructose corn syrup, hydrogenated oils, and excess calories. Focus on real, whole foods.

What is the success rate for curing fatty liver?

With aggressive lifestyle interventions, studies report the following success rates for reversing fatty liver:

  • Weight loss: Resolves steatosis in 45-80% of patients
  • Diet and exercise: Up to 80% improvement in steatosis and inflammation
  • Bariatric surgery: Over 90% NASH resolution
  • Pioglitazone: 45% histologic improvement in steatohepatitis
  • Vitamin E: Up to 43% NASH resolution

However, medications and natural treatments are generally less successful at reversing late stage fibrosis and cirrhosis. The best outcomes occur when fatty liver is caught early and weight loss interventions are implemented.

Table: Success rates for resolving fatty liver by treatment method

Treatment Success Rate
Weight loss 45-80% steatosis resolution
Diet and exercise Up to 80% improvement
Bariatric surgery Over 90% NASH resolution
Pioglitazone 45% histologic improvement
Vitamin E Up to 43% NASH resolution


In summary, yes fatty liver disease often can be completely resolved, especially when caught early. Weight loss through diet, exercise or bariatric surgery offers the best chance for true reversal of liver fat, inflammation and fibrosis. Lifestyle interventions should be supported with medications and supplements in more severe cases. A comprehensive treatment plan customized to the individual gives the highest likelihood of curing fatty liver back to health.
