Fatty Liver Disease: 10 Health Risks and Long-Term Consequences

Non-alcoholic fatty liver disease (NAFLD) and its progressive form (NASH) carry systemic risks beyond the liver:

1. Liver progression: Steatosis → NASH → fibrosis → cirrhosis → hepatocellular carcinoma (HCC).
2. Cardiovascular disease: Independent risk factor for coronary artery disease, heart failure, arrhythmias.
3. Type 2 diabetes: Bidirectional link; hepatic insulin resistance drives hyperinsulinemia and β-cell stress.
4. Obesity/metabolic syndrome: Central adiposity fuels hepatic lipogenesis; weight loss is cornerstone therapy.
5. Dyslipidemia: Elevated triglycerides, small dense LDL, low HDL—accelerates atherosclerosis.
6. HCC risk: 10–20× increased in cirrhosis; surveillance (ultrasound ± AFP q6mo) recommended.
7. Fatigue/cognitive decline: Associated with systemic inflammation, mitochondrial dysfunction; possible dementia link.
8. Abdominal discomfort: Hepatomegaly stretches Glisson’s capsule; right upper quadrant pain.
9. Cutaneous signs: Spider angiomas, palmar erythema, caput medusae (if portal hypertension).
10. Extrahepatic cancers: Increased risk of colorectal, breast, pancreatic cancer.

Prevention & Management

• Weight loss (7–10% body weight reverses steatosis/fibrosis)
• Mediterranean diet, exercise, alcohol abstinence
• Control diabetes, hypertension, lipids
• Avoid hepatotoxins; review medications
• Regular monitoring (LFTs, elastography, HCC surveillance if cirrhotic)
