Fatty liver, in simple terms, means that the liver is "oily." This indicates that there is an accumulation of fat within liver cells.
In Taiwan, approximately one-third of adults have fatty liver.
Common causes of fatty liver include obesity, hyperlipidemia, diabetes, excessive alcohol consumption, certain medications (such as steroids), and unknown reasons.
Among these, being overweight is the most common cause.
Additionally, during episodes of acute or chronic hepatitis, fat can also accumulate in the liver, leading to fatty liver.

The diagnosis of fatty liver is typically made through abdominal ultrasound or liver biopsy.
Is fatty liver a serious condition? This depends on the underlying cause of the fatty liver and whether your liver function is normal.
Therefore, it is essential to first check your liver function and then investigate potential causes of fatty liver (such as being overweight, having a history of alcohol abuse, diabetes, or high lipid levels).
If liver function is normal, there is generally no cause for concern, and regular monitoring is sufficient.
However, if liver function is abnormal and a cause can be identified (such as being overweight or hyperlipidemia), it is crucial to address these underlying issues (for example, by abstaining from alcohol, controlling diet, and engaging in moderate exercise).

It is incorrect to solely rely on medications to improve fatty liver without addressing the underlying causes.
For instance, if fatty liver is caused by excessive alcohol consumption and liver function is abnormal, the appropriate course of action would be to stop drinking alcohol.
Attempting to take any medication to "save" your liver without abstaining from alcohol is not the correct approach.
Fatty liver caused by acute or chronic hepatitis usually resolves on its own after treatment of the hepatitis.

In recent years, due to Taiwan's economic development and excessive caloric intake, the incidence of fatty liver due to obesity has significantly increased, with a trend of occurring at younger ages.
Fatty liver caused by obesity serves as a warning sign for cardiovascular health, as fat accumulation in the liver can also deposit in the heart, blood vessels, and cerebral vessels, leading to atherosclerosis.
Therefore, weight loss is crucial for personal health.
If you need a clearer understanding of hepatitis, you can visit an internal medicine specialist for blood tests and ultrasound scans.

More Info

Fatty liver disease, or hepatic steatosis, is a condition characterized by the accumulation of excess fat in liver cells. It can be classified into two main types: alcoholic fatty liver disease, which is related to excessive alcohol consumption, and non-alcoholic fatty liver disease (NAFLD), which is associated with factors such as obesity, diabetes, and high cholesterol levels. In recent years, the prevalence of fatty liver disease has increased significantly, particularly in developed countries, due to rising obesity rates and sedentary lifestyles.

Causes of Fatty Liver Disease
The formation of fatty liver can be attributed to several factors:
1. Obesity: Excess body weight is the most common cause of fatty liver disease. Fat accumulation in the liver is often a result of an imbalance between calorie intake and energy expenditure.

2. Insulin Resistance: Conditions such as type 2 diabetes and metabolic syndrome can lead to insulin resistance, which promotes fat storage in the liver.

3. High Cholesterol and Triglycerides: Elevated levels of lipids in the blood can contribute to fat deposition in the liver.

4. Alcohol Consumption: Chronic alcohol intake can lead to alcoholic fatty liver disease, where the liver is unable to metabolize fats effectively.

5. Medications: Certain medications, including corticosteroids and some cancer treatments, can also lead to fat accumulation in the liver.

6. Rapid Weight Loss: Sudden weight loss can cause fat to be released from adipose tissue and deposited in the liver.

Dietary Precautions for Managing Fatty Liver Disease
If you have been diagnosed with fatty liver disease, dietary modifications are crucial for managing the condition and improving liver health. Here are some dietary tips to consider:
1. Reduce Caloric Intake: Aim for a balanced diet that promotes weight loss if you are overweight. Reducing overall caloric intake can help decrease liver fat.

2. Limit Saturated and Trans Fats: Avoid foods high in saturated fats (like fatty cuts of meat, full-fat dairy products, and fried foods) and trans fats (found in many processed foods). Instead, focus on healthy fats such as those found in avocados, nuts, seeds, and olive oil.

3. Increase Fiber Intake: Incorporate more fruits, vegetables, whole grains, and legumes into your diet. Fiber helps improve digestion and can aid in weight management.

4. Choose Lean Proteins: Opt for lean sources of protein, such as chicken, turkey, fish, and plant-based proteins like beans and lentils. These options can help you maintain muscle mass while losing fat.

5. Limit Sugar and Refined Carbohydrates: Reduce your intake of sugary foods and beverages, as well as refined carbohydrates like white bread and pastries. These can contribute to insulin resistance and fat accumulation in the liver.

6. Stay Hydrated: Drink plenty of water throughout the day. Staying hydrated is essential for overall health and can support liver function.

7. Moderate Alcohol Consumption: If you have non-alcoholic fatty liver disease, it is advisable to limit or eliminate alcohol consumption, as it can exacerbate liver damage.

8. Regular Meal Patterns: Eating smaller, more frequent meals can help regulate blood sugar levels and prevent overeating.

Lifestyle Modifications
In addition to dietary changes, incorporating regular physical activity is essential for managing fatty liver disease. Aim for at least 150 minutes of moderate-intensity aerobic exercise each week, along with strength training exercises at least twice a week. Exercise helps improve insulin sensitivity, promotes weight loss, and can reduce liver fat.

Conclusion
Managing fatty liver disease requires a comprehensive approach that includes dietary modifications, regular exercise, and lifestyle changes. By focusing on a balanced diet rich in whole foods, reducing unhealthy fats and sugars, and maintaining a healthy weight, you can significantly improve your liver health and overall well-being. Regular follow-ups with your healthcare provider are also important to monitor liver function and make necessary adjustments to your management plan.
