Liver disease

What is liver disease?

Liver disease encompasses conditions that impair liver structure and function, typically following a progression from inflammation to permanent scarring (cirrhosis).

• Non-alcoholic Fatty Liver Disease (NAFLD): Driven by metabolic factors like insulin resistance and obesity. It affects 25% of adults and is the leading cause of chronic liver disease.

• Alcohol-related Liver Disease (AFLD): Caused by toxic damage from sustained alcohol use. It progresses from reversible fatty liver to inflammation and, eventually, irreversible cirrhosis.

• Other Forms: Viral hepatitis (B and C), autoimmune conditions, and iron overload (haemochromatosis) and primary biliary cholangitis — all of which can be flagged through Elfcare's blood panel and imaging.

Common symptoms of liver disease

Liver disease is frequently asymptomatic in its early stages, in both NAFLD and AFLD. As the condition progresses, symptoms may include:

• Fatigue and low energy, often the earliest and most persistent symptom

• Discomfort or heaviness in the upper right abdomen

• Bloating or fluid retention

• Nausea or loss of appetite

• Jaundice (yellowing of the skin or eyes)

• Dark urine or pale stools

• Itchy skin

• Easy bruising or bleeding

Because early liver damage rarely causes pain, testing is the most reliable way to identify it before symptoms appear.

What causes liver disease?

NAFLD and AFLD have distinct primary causes, though metabolic risk factors can amplify both. Other forms have their own mechanisms.

NAFLD develops when excess fat accumulates in liver cells through:

• Obesity and excess visceral fat — the strongest risk factor

• Insulin resistance and type 2 diabetes

• High triglycerides and dyslipidaemia

• Poor diet — high in refined carbohydrates, sugar, and saturated fat

• Metabolic syndrome

AFLD develops through direct alcohol toxicity:

• Regular excess alcohol consumption damages hepatocytes directly

• Progression from fatty liver to hepatitis to cirrhosis depends on volume, duration, and pattern of drinking

• Genetic factors influence individual susceptibility to alcohol-related liver damage

• Nutritional deficiency (common in heavy drinkers) accelerates disease progression

Other causes include:

• Viral hepatitis B and C: chronic infection causes progressive liver inflammation and fibrosis

• Haemochromatosis: genetic iron overload; directly toxic to liver cells over decades

• Autoimmune hepatitis: immune-mediated liver cell destruction

• Medications and supplements: certain drugs cause hepatotoxicity with prolonged use

How is liver disease detected?

Detection combines abdominal MRI to visualize structure and fat with blood tests to assess function and metabolic risk.

Abdominal MRI & AMRA®: Elfcare's full body MRI images the liver directly, identifying fatty infiltration, structural changes consistent with fibrosis or cirrhosis, and any focal lesions. Elfcare's AMRA® body composition analysis measures liver fat percentage with clinical precision, the most direct and quantitative non-invasive tool available for NAFLD and AFLD assessment. A liver fat above 5% indicates steatosis, while levels over 10–15% require urgent intervention.

Blood tests assess liver function and the metabolic and lifestyle factors driving disease. Relevant markers in Elfcare's panel include:

• ALT & AST: Enzymes released when liver cells are injured; their ratio helps distinguish metabolic damage from alcohol-related disease.

• GGT & ALP: Sensitive markers for alcohol use, bile flow disruption, and early fatty liver.

• Bilirubin & Albumin: Measure the liver's ability to process waste and synthesize essential proteins.

• Ferritin: Screens for haemochromatosis (iron overload), a frequently missed cause of liver damage.

• HbA1c & Lipids: Identify insulin resistance and high triglycerides—the primary drivers of fatty liver (NAFLD).

• CRP: Monitors active systemic and liver-specific inflammation.

Elfcare’s MRI and blood tests monitor liver enzymes, lipid balance, and inflammation markers, helping you detect stress on your liver before symptoms or complications appear.

Why early detection matters

Liver disease is unique because it is often fully reversible in its early stages, but becomes permanent once significant scarring (fibrosis) occurs. Because this progression is silent, identifying fat accumulation or enzyme shifts early is the only way to intervene before function is compromised.

Early detection allows you to:

• Reverse damage: use precision data from AMRA® and blood markers to restore liver health through diet and lifestyle.

• Prevent iron overload: catching haemochromatosis early prevents decades of iron accumulation that leads to cirrhosis.

• Monitor trends: track enzyme levels to see how your body responds to changes in alcohol or sugar intake.

• Protect longevity: identify structural changes early if you have a family history of liver disease.

Knowing your liver's fat percentage and inflammatory markers gives you a clear window for action while your body is still capable of complete recover.

How Elfcare can help

Elfcare's abdominal MRI directly images the liver, and our AMRA® analysis quantifies liver fat percentage, providing a structural and quantitative picture of liver health that blood tests alone cannot give. This is particularly valuable for identifying early NAFLD and AFLD before enzymes become significantly elevated.

Our blood panel covers a comprehensive liver function profile — ALT, AST, GGT, ALP, bilirubin, albumin — alongside metabolic and iron markers. GGT in particular is a sensitive early indicator of alcohol-related liver stress and is included as standard.

If our MRI, AMRA® analysis, or blood tests identify a suspicious finding, we take care of further diagnostics or refer you to the appropriate specialist.
