Overview

Metabolic dysfunction-associated steatotic liver disease (MASLD) — previously known as non-alcoholic fatty liver disease (NAFLD) — happens when fat builds up in the liver alongside metabolic risk factors such as excess weight, high blood sugar, high cholesterol or high blood pressure. It is common, affecting roughly a quarter of adults, and in its early stages usually causes no symptoms at all. In a proportion of people it progresses to inflammation (MASH), scarring (fibrosis) and eventually cirrhosis, which is why early identification matters.

Common signs and symptoms

• Often no symptoms at all — frequently picked up on routine blood tests or scans
• Mild fatigue or discomfort under the right ribs
• Symptoms of more advanced disease: loss of appetite, unintentional weight loss, fluid retention

What to expect at A Bit of Life Clinic

Assessment includes liver blood tests and imaging — typically an ultrasound and, where needed, a fibroscan to check for liver stiffness and scarring. We review the metabolic risk factors driving the disease (weight, blood sugar, cholesterol, blood pressure) and build a practical plan to address them, alongside regular monitoring to catch any progression early and reduce the risk of cirrhosis or liver cancer over time.
