Jaundice

Definition:
Jaundice consists of a yellow discoloration of the skin, mucous membranes (tissue including that which lines the mouth), and whites of the eyes. It is a symptom that often occurs with liver and gallbladder disorders. It may also be present in certain blood disorders and is occasionally due to benign (normal) metabolic conditions.

Causes:
Jaundice occurs when excess bilirubin builds up in the blood. Bilirubin is a yellow-brown colored substance in the bile that is formed during the body's normal process of breaking down red blood cells. Bile is a liquid that carries waste products (including bilirubin) away from the liver. It also helps break down fats in the small intestine.

There are several reasons why too much bilirubin can build up in the blood. They include:

  • Excess breakdown of red blood cells, which can occur in:
    • Certain forms of anemia
    • Some infectious diseases like malaria
  • A blockage in or near the liver that prevents the flow of bile, such as:
    • Gallstones or pancreatitis
    • A tumor in the liver or bile duct
    • Cancer in the pancreas
    • Congenital defects, including biliary atresia
    • Pregnancy
  • Liver damage caused by:
    • Viral hepatitis
    • Cirrhosis
    • Alcoholic liver disease
    • Adverse effects of certain medications or environmental toxins
  • In babies, insufficient amounts of a certain liver enzyme during the first two weeks of life; possibly made worse by breastfeeding
  • Inherited metabolic disorders, including Gilbert's, Crigler-Nager, and Dubin-Johnson syndromes
Risk Factors:
A risk factor is something that increases your chance of getting a disease or condition. The risk factors for jaundice are those that increase the risk for liver and gallbladder disorders. They include:
  • Drinking too much alcohol
  • Use of illegal drugs
  • Taking medications that may harm the liver
  • Exposure to hepatitis A (through contaminated food or water), or hepatitis B, or C (through contaminated needles or unsafe sex)
  • Exposure to certain industrial chemicals
Symptoms:
Jaundice appears as a yellow discoloration of the skin, mucous membranes, and/or whites of the eyes.

Other symptoms may occur with jaundice depending on the specific disorder that causes it.

Diagnosis:
If you have jaundice, the doctor will ask about your symptoms and medical history, and perform a physical exam.

Tests may include:

  • Blood Tests–Tests to detect elevated bilirubin and liver enzyme levels, or other abnormalities related to the suspected cause of jaundice.
  • Ultrasound–A test that uses sound waves to examine internal organs, in this case, the liver, gallbladder, and bile ducts.
  • CT Scan–A type of x-ray that uses a computer to make pictures of the inside of the body, in this case, the liver, gallbladder, bile ducts, and surrounding tissues.
  • Cholangiography–An invasive test that uses x-rays and a large needle inserted into the liver to examine the gall bladder and bile ducts. This is sometimes performed during abdominal surgery.
  • ERCP Test–A test that combines x-rays and an endoscope, which is a long, flexible, lighted tube that is inserted down the throat. This is done to examine the duodenum (first part of the small intestine), bile ducts, and pancreatic ducts.
  • Laparoscopy–Insertion of a tube and other instruments through small incisions in the abdominal wall to directly view the liver, gallbladder, bile ducts, and other structures.
  • Liver Biopsy–Removal of a sample of liver tissue for testing. This is usually done with a long needle.
Treatment:
Mild jaundice in newborns is common and usually clears without treatment. If bilirubin levels rise above a certain level, the baby may receive phototherapy, which is treatment with a special ultraviolet light. In Gilbert's syndrome, jaundice tends to occur during stressful periods and clears without treatment.

In most other types of jaundice, the specific condition causing it must be treated. There are many treatments that may be used for liver and gallbladder problems depending on the exact condition. They include:

  • Avoiding a substance (alcohol or a medicine) that is causing the condition
  • Addressing the cause of anemia
  • Taking medications to treat causative infectious diseases
  • Relieving bile duct obstructions by
    • Excising tumors
    • Extracting gallstones
    • Removing the gallbladder
    • Treating inflammation of the pancreas, called pancreatitis
Prevention:
Prevention depends on the disorder causing the jaundice. You may not be able to prevent some of the disorders. However, you can take the steps below to help decrease your chance of developing liver disease:
  • Limit your alcohol intake to no more than two drinks a day for men or one drink a day for women.
  • Be careful in mixing drugs, especially alcohol, with over-the-counter and prescription medicines.
  • Avoid exposure to industrial chemicals.
  • Do not use illegal drugs.
  • Do not share needles or nasal snorting equipment.
  • Practice safe sex.
  • To decrease your risk of hepatitis B, get the hepatitis B vaccine.
  • To decrease your risk of hepatitis A, get a hepatitis A vaccine
