Jaundice is a clinical condition characterized by the yellowish discoloration of the skin, sclerae (whites of the eyes), and mucous membranes, resulting from the accumulation of bilirubin in the body. It is not a disease in itself but a manifestation of underlying pathology, often related to liver dysfunction, biliary obstruction, or hemolysis.
This comprehensive article dives into the clinical features of jaundice, explores the pathophysiology, diagnostic approach, and associated systemic clues, and introduces the powerful and illustrative mnemonic “JAUNDICE Presents With Fever, Hemorrhage, Weight Loss, XYZ”—a tool for learners and clinicians to identify key signs efficiently.
What is Jaundice?
Jaundice occurs when there is an imbalance between bilirubin production and clearance. Bilirubin is formed from the breakdown of heme-containing proteins, primarily hemoglobin.
Bilirubin metabolism has three phases:
- Pre-hepatic (Hemolytic) – Excess breakdown of RBCs
- Hepatic – Impaired conjugation or uptake in the liver
- Post-hepatic (Obstructive) – Blockage in the bile ducts
Understanding these categories helps in diagnosing the type of jaundice, guiding the investigation and management.
Mnemonic: “JAUNDICE Presents With Fever, Hemorrhage, Weight Loss, XYZ”
To systematically remember the clinical features, the mnemonic breaks down the common presentations associated with jaundice:
| Letter | Clinical Feature |
|---|---|
| J | Jaundice (yellow skin and eyes) |
| A | Abdominal pain |
| U | Urine is dark / urobilinogen absent |
| N | Neoplasm (e.g., liver cancer) |
| D | Deep jaundice with greenish hue |
| I | Irregular, hard, large liver |
| C | Cholestasis |
| E | ERCP or MRCP to investigate |
| P | Pruritus / Pale (clay-colored) stools |
| W | Weight loss |
| F | Fever with chills and rigor |
| H | Hemorrhagic tendency (Vitamin K deficiency) |
| X | Weight loss due to malabsorption |
| Y | Xanthomas and yellowish discoloration of skin/mucosa |
Let’s now explore each clinical feature in detail.
J – Jaundice
The hallmark sign of elevated serum bilirubin, leading to:
- Yellow discoloration of skin, sclera, nail beds
- First seen in the sclera (due to high elastin binding)
- Occurs when bilirubin > 2.5–3 mg/dL
Clinical Tip: Examine under natural light; artificial lighting may mask jaundice.
A – Abdominal Pain
Abdominal discomfort or pain is common in:
- Acute hepatitis (right upper quadrant tenderness)
- Gallstones or biliary colic
- Pancreatitis or cholangiocarcinoma
Pain characteristics help localize the cause:
- Cramping → biliary colic
- Dull ache → liver pathology
- Sharp, radiating → pancreatic involvement
U – Urine is Dark / Urobilinogen Absent
Dark-colored urine results from:
- Conjugated hyperbilirubinemia, which is water-soluble and excreted in urine
- Common in obstructive jaundice
In pre-hepatic jaundice, urine remains normal-colored, but urobilinogen may increase.
N – Neoplasm (Liver or Biliary Tract)
Cancers associated with jaundice:
- Hepatocellular carcinoma (HCC)
- Cholangiocarcinoma
- Pancreatic head cancer
- Gallbladder carcinoma
Signs of malignancy:
- Rapid weight loss
- Hard, nodular liver
- Deepening jaundice
- Upper abdominal mass
D – Deep Jaundice with Greenish Hue
Very high levels of conjugated bilirubin cause:
- Intensely yellow to greenish skin hue
- Seen in prolonged obstructive jaundice
- Often associated with cholangitis or malignancy
I – Irregular, Hard, Large Liver
Palpation may reveal:
- Firm or hard hepatomegaly – seen in metastatic disease
- Irregular margins – suggestive of liver tumors or cirrhosis
- Tender hepatomegaly – hepatitis, congestive hepatopathy
Liver texture and size provide valuable diagnostic clues.
C – Cholestasis
Cholestasis refers to impaired bile flow, presenting with:
- Conjugated hyperbilirubinemia
- Pale stools (lack of stercobilin)
- Dark urine
- Elevated alkaline phosphatase (ALP) and GGT
It can be intrahepatic (e.g., drug-induced) or extrahepatic (e.g., gallstones, tumors).
E – ERCP or MRCP to Investigate
When structural causes are suspected, imaging helps:
- ERCP (Endoscopic Retrograde Cholangiopancreatography) – Diagnostic + therapeutic
- MRCP (Magnetic Resonance Cholangiopancreatography) – Non-invasive, excellent for bile ducts
- Ultrasound/CT scan – Initial assessment for gallstones, masses, obstruction
These tools guide management, especially in obstructive or malignant causes.
P – Pruritus / Pale Clay-Colored Stools
Pruritus (itching) is common in cholestatic jaundice due to bile salt accumulation.
Pale stools indicate lack of bile pigments in feces, often due to:
- Bile duct obstruction
- Cholangiocarcinoma
- Pancreatic carcinoma
It’s a key differentiator between conjugated and unconjugated jaundice.
W – Weight Loss
Occurs due to:
- Malignancy-related cachexia
- Chronic liver disease with muscle wasting
- Fat malabsorption due to bile salt deficiency
Weight loss often points toward serious or chronic pathology.
F – Fever with Chills and Rigor
Classically seen in:
- Acute cholangitis (Charcot’s triad: fever, jaundice, RUQ pain)
- Liver abscess
- Sepsis secondary to biliary obstruction
Immediate medical attention is warranted in these situations due to risk of septic shock.
H – Hemorrhagic Tendency (Vitamin K Deficiency)
Cholestasis leads to impaired bile-mediated absorption of fat-soluble vitamins, especially:
Vitamin K → needed for clotting factor synthesis (II, VII, IX, X)Manifestations:
- Easy bruising
- GI bleeding
- Prolonged PT/INR
Vitamin K supplementation and coagulation monitoring are crucial in these patients.
X – Weight Loss (Malabsorption)
Chronic cholestasis or liver disease causes:
- Impaired digestion of fats and fat-soluble vitamins
- Steatorrhea (fatty stools)
- Deficiency of vitamins A, D, E, K
Malnutrition worsens prognosis and immune function in these patients.
Y – Xanthomas / Yellow Discoloration of Skin and Mucosa
Xanthomas are lipid-laden skin deposits, often seen in:
- Primary biliary cholangitis (PBC)
- Cholestatic syndromes with hyperlipidemia
They often appear over:
- Eyelids (xanthelasma)
- Tendons
- Buttocks
Yellow discoloration (true jaundice) involves skin, mucosa, conjunctivae—visible and diagnostic.
Types of Jaundice: A Quick Overview
| Type | Cause | Clinical Hint |
|---|---|---|
| Pre-hepatic | Hemolysis (e.g., malaria, thalassemia) | Unconjugated bilirubin, normal urine color |
| Hepatic | Hepatitis, cirrhosis, drugs | Mixed bilirubin pattern, ALT/AST elevated |
| Post-hepatic | Gallstones, tumors, strictures | Conjugated bilirubin, pale stools, pruritus |
Diagnostic Workup
1. Laboratory Tests:
- Liver function tests (ALT, AST, ALP, GGT, bilirubin fractions)
- PT/INR (for clotting status)
- CBC (for hemolysis or infection)
2. Imaging:
- Ultrasound abdomen
- MRCP/CT scan
- ERCP if therapeutic intervention needed
- Viral hepatitis panel
- Autoimmune markers (ANA, AMA)
- Tumor markers (AFP, CA 19-9)
Management Approach
Treatment depends on the underlying cause:
- Pre-hepatic: Manage hemolysis (e.g., antimalarials, transfusion)
- Hepatic: Antivirals, steroids, lifestyle modification, liver support
- Obstructive: ERCP + stenting, cholecystectomy, surgery for tumors
Supportive measures:
- Vitamin K injections
- Ursodeoxycholic acid for cholestasis
- Nutritional support with fat-soluble vitamins
- Monitoring of complications (encephalopathy, bleeding, infection)

Frequently Asked Questions (FAQ)
Q1: What is the earliest sign of jaundice?
A: Yellow discoloration of the sclera (scleral icterus) is usually the first visible sign.
Q2: What does pale-colored stool suggest?
A: Indicates lack of bile pigment, commonly seen in obstructive jaundice.
Q3: Can jaundice be life-threatening?
A: Yes, especially when associated with acute liver failure, sepsis, or malignancy.
