Ultrasound (USG) Features

Ultrasound may show:

• Degree of fibrosis/scarring
• Fat accumulation

Benefits:

• Painless
• Quick procedure
• Helps avoid unnecessary liver biopsy in many patients

Grades of Fatty Liver

Grade 1

• Mild fat accumulation
• Usually reversible with lifestyle modification

Grade 2

• Moderate fatty infiltration
• Higher metabolic risk

Grade 3

• Severe fatty liver
• Increased risk of fibrosis and cirrhosis

---

Possible Complications

If untreated, fatty liver may lead to:

• Liver inflammation (Steatohepatitis)
• Fibrosis
• Liver cirrhosis
• Liver failure
• Increased cardiovascular risk
• Diabetes progression
• Rarely liver cancer

Red Flags in Fatty Liver

Seek medical evaluation if associated with:

• Persistent abdominal pain
• Jaundice
• Swelling of the abdomen
• Leg swelling
• Vomiting blood
