Can fatty liver disease be reversed?

Yes, early-stage fatty liver can often be reversed with weight loss, dietary changes, and regular exercise. Even a 5–10% reduction in body weight can significantly reduce liver fat.

Is fatty liver disease serious?

Simple fatty liver is generally benign, but when it progresses to NASH with inflammation and scarring, it can lead to cirrhosis, liver failure, and liver cancer. Early detection and lifestyle changes are crucial.

Do I need to avoid all fat if I have fatty liver?

No, healthy fats from olive oil, nuts, avocados, and fatty fish are beneficial. The key is to reduce saturated fats, trans fats, and added sugars while following a Mediterranean-style eating pattern.

Fatty Liver Disease

Also known as: NAFLD, Non-Alcoholic Fatty Liver Disease, MASLD, Hepatic Steatosis

Fatty liver disease occurs when excess fat accumulates in liver cells, and is the most common liver disorder in developed countries. Non-alcoholic fatty liver disease (NAFLD) can progress to NASH, which involves inflammation and can lead to cirrhosis and liver failure. Lifestyle modifications, particularly weight loss and exercise, are the cornerstone of treatment.

Symptoms

Often asymptomatic in early stages

Fatigue and general weakness

Dull pain or discomfort in the upper right abdomen

Unexplained weight loss in advanced stages

Enlarged liver detectable on physical exam

Jaundice in advanced disease

Abdominal swelling from fluid accumulation (ascites)

Causes

Insulin resistance and metabolic syndrome
Obesity, particularly visceral fat
High-sugar and high-fat diets
Genetic predisposition (PNPLA3 gene variants)
Sedentary lifestyle

Risk Factors

Obesity or overweight
Type 2 diabetes or prediabetes
High cholesterol and triglycerides
Metabolic syndrome
Polycystic ovary syndrome
Obstructive sleep apnea

Diagnosis

Blood tests showing elevated liver enzymes (ALT, AST)
Abdominal ultrasound revealing fatty infiltration
FibroScan (transient elastography) to assess liver stiffness
Liver biopsy to confirm NASH and assess fibrosis stage
MRI-based techniques for quantifying liver fat

Treatment

Weight loss of 7–10% of body weight through diet and exercise
Mediterranean diet rich in healthy fats, whole grains, and vegetables
Regular aerobic and resistance exercise
Management of diabetes, cholesterol, and blood pressure
Vitamin E supplementation for non-diabetic NASH patients
Emerging therapies such as resmetirom for NASH

Prevention

Maintain a healthy weight
Follow a balanced, plant-forward diet
Exercise at least 150 minutes per week
Limit added sugars and processed foods
Avoid excessive alcohol consumption

When to See a Doctor

Blood tests show persistently elevated liver enzymes
You have risk factors for NAFLD such as obesity or diabetes
You experience persistent fatigue or upper abdominal discomfort
Yellowing of the skin or eyes develops
