6. Abnormal blood test results
Blood tests are critical in detecting and monitoring liver disease. Elevated liver enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) indicate liver cell injury. Gamma-glutamyl transferase (GGT) levels may also be raised, signaling bile duct involvement or alcohol-related liver damage.
Other important blood markers include bilirubin levels, albumin concentration, and prothrombin time, which reflect liver function and synthetic capacity. Persistent abnormalities in these tests can suggest chronic liver disease requiring further diagnostic imaging or biopsy.
Regular monitoring of these markers is essential for individuals with risk factors like obesity, diabetes, or metabolic syndrome to catch liver disease early.
7. Risk factors assessment
Identifying risk factors for liver disease helps prioritize screening and preventive measures. Key risk factors include:
- Obesity and central adiposity (large waist circumference)
- Type 2 diabetes and insulin resistance
- High cholesterol and triglycerides
- Excessive alcohol intake
- Metabolic syndrome components such as hypertension
People with these conditions are more prone to developing non-alcoholic fatty liver disease (NAFLD) and its progressive form, NASH, which can lead to cirrhosis and liver cancer if untreated.
8. Fluid buildup in abdomen
Ascites, the accumulation of fluid in the abdominal cavity, is a serious sign of advanced liver disease, often indicating cirrhosis or portal hypertension. This fluid buildup causes noticeable abdominal swelling and discomfort.
Ascites increases the risk of infection and kidney dysfunction, requiring medical treatment such as diuretics, salt restriction, or paracentesis (fluid removal). Early recognition of fluid accumulation in patients with liver disease is crucial to reduce complications.
