Symptom/Sign | Description |
---|---|
Fatigue | A common early symptom of cirrhosis, often due to decreased liver function and the body's inability to detoxify the blood. |
Jaundice | Yellowing of the skin and eyes caused by the buildup of bilirubin due to impaired liver function. |
Ascites | Accumulation of fluid in the abdominal cavity, leading to abdominal distension and discomfort. |
Hepatomegaly | Enlargement of the liver, often felt as a firm, enlarged liver on physical examination. |
Splenomegaly | Enlargement of the spleen, often associated with portal hypertension and hypersplenism. |
Spider Angiomas | Small, spider-like blood vessels visible under the skin, commonly found on the face, neck, and chest. |
Palmar Erythema | Reddening of the palms due to increased estrogen levels as the liver's ability to metabolize hormones is impaired. |
Caput Medusae | Visible, distended veins around the umbilicus due to portal hypertension. |
Gynecomastia | Enlargement of breast tissue in males, caused by an imbalance of sex hormones due to liver dysfunction. |
Clubbing | Thickening of the fingertips with loss of the normal angle between the nail and the nail bed, often seen in chronic liver disease. |
Confusion or Encephalopathy | Changes in mental status, ranging from mild confusion to deep coma, due to the accumulation of toxins (e.g., ammonia) that the liver can no longer detoxify. |
Pruritus | Generalized itching due to the buildup of bile salts in the skin. |
Bruising or Bleeding | Increased tendency to bruise or bleed easily, due to impaired synthesis of clotting factors by the liver. |
Weight Loss and Muscle Wasting | Unintentional weight loss and loss of muscle mass, common in advanced cirrhosis due to malnutrition and protein catabolism. |
Peripheral Edema | Swelling in the legs, ankles, and feet due to fluid retention, often associated with hypoalbuminemia and portal hypertension. |
Severity Assessment | Cause | Clinical Presentation | Investigations | Treatment |
---|---|---|---|---|
Child-Pugh Score
Assesses the severity of cirrhosis based on bilirubin, albumin, INR, ascites, and hepatic encephalopathy. Classified into A (mild), B (moderate), and C (severe). |
Varies, often chronic liver diseases such as viral hepatitis, alcohol-related liver disease, NAFLD. | Ascites, jaundice, variceal bleeding, encephalopathy, fatigue, edema. | Liver function tests (LFTs), ultrasound, CT/MRI, endoscopy, serum albumin, bilirubin, INR. | Lifestyle modification, management of complications, monitoring for progression, liver transplantation in severe cases. |
MELD Score (Model for End-Stage Liver Disease)
Predicts survival, uses bilirubin, creatinine, and INR levels. Scores range from 6 to 40, with higher scores indicating greater severity. |
Alcoholic liver disease, viral hepatitis, cholestatic liver diseases, autoimmune hepatitis. | Fatigue, weakness, jaundice, ascites, GI bleeding, hepatic encephalopathy. | MELD calculation based on bilirubin, creatinine, INR, sodium. Regular monitoring of liver function, imaging for liver morphology. | Management of complications, referral for liver transplantation evaluation, nutritional support, and control of risk factors. |
Compensated vs. Decompensated Cirrhosis
Compensated: asymptomatic or mild symptoms. Decompensated: presence of ascites, variceal haemorrhage, jaundice, or hepatic encephalopathy. |
Chronic hepatitis B/C, alcoholic liver disease, NAFLD, genetic disorders (e.g., haemochromatosis, Wilson’s disease). | Compensated: asymptomatic or vague symptoms like fatigue.
Decompensated: severe symptoms such as ascites, jaundice, variceal bleeding, encephalopathy. |
Ultrasound, LFTs, endoscopy for varices, serum sodium, creatinine, and liver biopsy if necessary. | Compensated: surveillance and preventive care.
Decompensated: aggressive management of complications, referral for liver transplantation. |
Liver Biopsy
Provides histological assessment of fibrosis and cirrhosis severity. |
NAFLD, chronic viral hepatitis, autoimmune hepatitis, alcohol-induced liver damage. | Jaundice, pruritus, fatigue, hepatomegaly, spider angiomas, palmar erythema. | Liver biopsy with staging of fibrosis (F0-F4), imaging studies, elastography for non-invasive fibrosis assessment. | Medical management tailored to underlying cause, antifibrotic therapy, regular monitoring of disease progression, consideration for liver transplantation. |
Transient Elastography (FibroScan)
Non-invasive method to assess liver stiffness and estimate fibrosis stage. |
Chronic viral hepatitis, alcohol-related liver disease, NAFLD, cholestatic liver diseases. | Fatigue, right upper quadrant pain, jaundice, pruritus, signs of portal hypertension (e.g., splenomegaly, varices). | FibroScan for liver stiffness, LFTs, imaging for liver and spleen morphology, assessment of portal hypertension. | Lifestyle changes, antiviral therapy for viral hepatitis, management of complications, consideration of liver transplantation for advanced fibrosis/cirrhosis. |
