Fatty Liver Symptoms: Warning Signs + What to Know

Metabolic dysfunction‑associated steatotic liver disease (MASLD), historically known as Non‑alcoholic fatty liver disease (NAFLD), is often called a “silent” disease — many people never notice anything is wrong.

But when symptoms do show up, they tend to be subtle. Early awareness can help you address the issue before it evolves into more serious liver damage.

Why Fatty Liver Is Often “Invisible”

  • MASLD/NAFLD causes no obvious symptoms in many cases — often only detected via bloodwork or imaging.
  • Because it develops gradually, people often don’t suspect liver involvement until later.

Most Common Early Warning Signs of Fatty Liver

  • Persistent fatigue or low energy*
  • Dull ache or discomfort under the right ribs
  • General “unwell” feeling or lethargy

How Fatty Liver Is Diagnosed

  • Blood tests (e.g., ALT/AST)
  • Imaging: Ultrasound, CT, MRI, Fibroscan

Top Risk Factors

  • Insulin resistance or type 2 diabetes
  • High triglycerides or low HDL cholesterol
  • Sedentary lifestyle and low confidence in diet
