In simple terms

Non-alcoholic fatty liver disease is now the most common chronic liver disease worldwide, driven by metabolic syndrome.

What you need to remember

  • DiagnosisOften discovered incidentally on imaging or via elevated liver enzymes.
  • TreatmentWeight loss of 7-10% reverses inflammation
  • Coffee and exerciseTwo to three cups of coffee daily and regular exercise reduce progression independently of weight.

Fat accumulation alone is usually benign, but 20% develop steatohepatitis with inflammation, fibrosis, and risk of cirrhosis.

Diagnosis

Often discovered incidentally on imaging or via elevated liver enzymes. Non-invasive scores (FIB-4) and elastography assess fibrosis risk.

Treatment

  • Weight loss of 7-10% reverses inflammation
  • Mediterranean diet and physical activity
  • GLP-1 analogs and resmetirom for advanced disease
  • Treat coexisting diabetes, hypertension and dyslipidaemia aggressively

Coffee and exercise

Two to three cups of coffee daily and regular exercise reduce progression independently of weight.

Even modest weight loss (5%) measurably reduces liver fat and inflammation.

The words explained

Medical terms used above, in everyday language.

Inflammation
The body's reaction to injury or irritation: redness, swelling, heat or pain.
Diagnosis
The moment a doctor identifies which illness is causing your symptoms.
Blood pressure
The force of blood pushing against your artery walls. Too high, over years, damages the heart and vessels.

When should you see a doctor?

  • Your symptoms last more than a few weeks or keep coming back.
  • They get worse quickly, or stop you doing everyday things.
  • You notice sudden pain, breathing trouble, fainting or bleeding — seek urgent care.
  • You already take medication and want to change anything about it.
