Understanding Jaundice: Types, Causes, and Clinical Signs  A Herbal & Modern Correlation

What Is Jaundice?

Jaundice is a clinical condition in which the skin, eyes, and mucous membranes become yellow due to increased bilirubin levels in the blood. Bilirubin is a yellow pigment formed during the breakdown of red blood cells. Normally, the liver processes bilirubin and removes it through bile into the intestine.

When the liver, bile ducts, or gallbladder are affected, bilirubin accumulates in the bloodstream, producing the characteristic yellow discoloration known as jaundice.

Role of the Liver and Gallbladder

The liver is one of the body’s major detoxifying organs and plays a central role in metabolism, digestion, and bile production.

The gallbladder lies beneath the liver and stores bile. Bile travels through bile ducts into the intestine, where it helps digest fats.

When inflammation, obstruction, infection, or liver cell injury interferes with bile flow, bilirubin cannot be excreted properly. This results in jaundice and may also increase liver enzyme levels such as:

S.G.P.T / ALT (Alanine Aminotransferase) — marker of liver cell stress or inflammation

Serum Bilirubin (S.B.R) — measures bilirubin concentration in blood

How to Check Jaundice

Important Laboratory Tests

1. Liver Function Test (L.F.T)

This panel evaluates liver health and includes:

ALT / S.G.P.T

AST / S.G.O.T

Alkaline Phosphatase (ALP)

Total and Direct Bilirubin

Albumin

2. Serum Bilirubin Test

Measures bilirubin accumulation in blood.

Typical categories:

Mild elevation

Moderate jaundice

Severe hyperbilirubinemia

3. Ultrasound Examination

Ultrasound helps detect:

Gallstones

Bile duct obstruction

Fatty liver

Liver abscess

Enlargement of liver or gallbladder

Understanding S.G.P.T / ALT

S.G.P.T (ALT) rises when liver cells become inflamed or damaged.

Common causes of elevated ALT include:

Viral hepatitis

Fatty liver disease

Alcohol-related liver injury

Drug toxicity

Bile duct obstruction

Liver abscess

Clinical Correlation

Higher values generally indicate greater hepatic stress, although interpretation depends on the patient’s condition and associated laboratory findings.

Main Types of Jaundice

1. Obstructive Jaundice

Obstructive jaundice occurs when bile flow is blocked.

Common Causes

Gallstones

Bile duct narrowing

Tumors or lesions

Liver abscess

Parasitic obstruction

Because bile cannot reach the intestine, bilirubin enters the bloodstream.

Common Features

Dark urine

Pale or clay-colored stool

Severe itching

Elevated bilirubin and ALP

Pain below right costal margin

2. Inflammatory / Catarrhal Jaundice

Traditionally described in herbal and Unani medicine as “Balghami” or catarrhal jaundice.

In this condition:

Inflammation narrows the bile ducts

Mucosal swelling obstructs bile flow

Duodenal inflammation may spread to nearby bile passages

This correlation resembles inflammatory hepatobiliary disorders recognized in modern medicine.

3. Fatty Liver–Associated Jaundice

Fat accumulation in liver cells may impair normal hepatic function.

Risk factors include:

Obesity

Diabetes

High-fat diet

Alcohol use

Metabolic syndrome

In advanced cases, bilirubin metabolism becomes impaired.

4. Hepatic Inflammatory Jaundice

Occurs when liver tissue itself becomes inflamed.

Possible causes:

Viral hepatitis

Drug-induced liver injury

Autoimmune disease

Toxic exposure

Pathophysiology of Jaundice

Normal bile flow pathway:

When obstruction or inflammation develops:

As bilirubin accumulates:

Skin becomes yellow

Eyes develop scleral icterus

Urine darkens

Stool loses normal pigmentation

Etiology & Mechanisms

Several mechanisms contribute to jaundice:

Hepatocellular Injury

Damage to liver cells impairs bilirubin processing.

Ductal Obstruction

Blockage prevents bile from entering the intestine.

Inflammatory Narrowing

Inflammation of the duodenum or bile ducts causes reduced bile flow.

Calculi or Helminths

Gallstones or intestinal parasites may obstruct the ducts.

Clinical Signs and Symptoms

Urinary Changes

Thick yellow urine

Dark brown urine

Occasionally blackish discoloration

The most common presentation is concentrated deep-yellow urine.

Stool Changes

Dry stool

Pale or clay-colored stool

This occurs because bile pigments fail to reach the intestine.

Gastrointestinal Symptoms

Constipation

Nausea

Vomiting

Loss of appetite

Abdominal distension

Ocular and Oral Findings

Yellow sclera (icterus)

Dry palate

Bitter taste in mouth

Skin Manifestations

Pruritus (itching)

Xerosis (dry skin)

Visual Symptoms

Some patients experience:

Xanthopsia — yellow-tinted vision

General Symptoms

Weakness (asthenia)

Irritability

Fatigue

Low morale

Physical Examination

Tenderness may be present below the right costal margin, especially in inflammatory or obstructive conditions.

Herbal & Traditional Correlation

Traditional herbal and Unani systems historically associated jaundice with:

Hepatic heat and inflammation

Obstruction of bile pathways

Digestive imbalance

Excess phlegmatic or bilious states

Supportive herbal approaches have traditionally included:

Bitter hepatotonic herbs

Digestive stimulants

Mild cholagogues

Hydration support

Dietary moderation

However, modern evaluation is essential because jaundice may indicate serious liver or biliary disease requiring urgent medical treatment.

Important Medical Warning

Seek immediate medical attention if jaundice is accompanied by:

Fever

Severe abdominal pain

Confusion

Persistent vomiting

Bleeding tendency

Rapid worsening yellow discoloration

These may indicate acute liver failure or severe biliary obstruction.

Conclusion

Jaundice is not a disease itself but a sign of underlying hepatic or biliary dysfunction. Understanding the relationship between bilirubin metabolism, bile flow, liver enzymes, and clinical symptoms helps in early recognition and treatment.

Modern diagnostic tools such as:

L.F.T

S.G.P.T / ALT

Serum Bilirubin

Ultrasound

combined with traditional supportive approaches may help provide a broader understanding of hepatobiliary health in integrative medicine.
