Fatty liver is a condition in which excess fat builds up in the liver. It’s increasingly common and can be either benign or lead to more serious liver problems if untreated. Here’s a detailed overview:
Types of Fatty Liver
- Non-alcoholic fatty liver disease (NAFLD):
- Fat accumulates in the liver without significant alcohol consumption
- Often associated with obesity, diabetes, high cholesterol, or metabolic syndrome
- Alcoholic fatty liver disease:
- Caused by heavy alcohol use
- Can progress to more serious liver disease if drinking continues
Symptoms
Fatty liver is often silent in early stages, but some people may experience:
- Fatigue or weakness
- Mild discomfort in the upper right abdomen
- Enlarged liver (detected on imaging)
Advanced stages (nonalcoholic steatohepatitis, NASH) may cause:
- Jaundice (yellowing of the skin/eyes)
- Swelling in the abdomen or legs
- Confusion or fatigue
Risk Factors
- Overweight or obesity
- Type 2 diabetes or insulin resistance
- High cholesterol or triglycerides
- Poor diet (high in sugar, refined carbs, or saturated fats)
- Sedentary lifestyle
- Excessive alcohol consumption (for alcoholic fatty liver)
Diagnosis
- Blood tests (liver enzymes like ALT and AST)
- Ultrasound, CT scan, or MRI to detect fat in the liver
- Sometimes liver biopsy to check inflammation or fibrosis
Treatment & Management
- Lifestyle changes (most effective):
- Weight loss (gradual 5–10% reduction can improve liver health)
- Healthy diet: low in added sugars, refined carbs, and saturated fats; high in vegetables, fruits, lean protein, and whole grains
- Regular exercise: 150 minutes of moderate aerobic activity per week
- Control related conditions:
- Manage diabetes, high blood pressure, and high cholesterol
- Avoid alcohol: Especially important for alcoholic fatty liver
- Medications: Currently, no FDA-approved drugs for NAFLD; treatment focuses on underlying conditions
Prevention
- Maintain a healthy weight
- Eat a balanced diet rich in fiber and healthy fats
- Exercise regularly
- Limit alcohol consumption
- Avoid unnecessary medications that strain the liver
Fatty liver is reversible in its early stages with proper lifestyle changes, making early detection and management crucial.
