Jaundice is the medical term that describes
yellowing of the skin and eyes. Jaundice itself is not a disease but it is a
symptom of several possible underlying illnesses. Jaundice forms when there is
too much bilirubin in your system. Bilirubin is a yellow pigment that
is formed by the breakdown of dead red blood cells in the liver. Normally, the
liver gets rid of bilirubin along with old red blood cells.
Jaundice may indicate a serious problem with the
function of your red blood cells, liver, gallbladder, or pancreas.
Yellow-tinted skin and eyes characterize jaundice.
In more severe cases, the whites of your eyes may turn brown or orange-colored.
You may also have dark urine and pale stools.
If an underlying health condition such as viral
hepatitis is to blame for the jaundice, you might experience other symptoms,
such as excessive fatigue and vomiting.
Some people misdiagnose themselves when they
experience yellow skin. According to the Merck Manual,
patients who have jaundice usually have both yellow-colored skin and yellow-colored
eyes. If you only have yellow skin, it’s maybe due to having too much beta carotene
in your system. Beta carotene is an antioxidant found in foods such
as carrots, pumpkins, and sweet potatoes. An excess of this antioxidant is not
a cause of jaundice.
Causes of jaundice
Old red blood cells travel to your liver, where
they’re broken down. Bilirubin is the yellow pigment formed by the breakdown of
these old cells. Jaundice occurs when your liver doesn’t metabolize bilirubin
the way it’s supposed to.
Your liver might be damaged and unable to perform
this process. Sometimes, the bilirubin simply can’t make it to your digestive
tract, where it normally would be removed through your stool. In other cases,
there may be too much bilirubin trying to enter the liver at once, or too many
red blood cells dying at one time.
Jaundice in adults is often indicative of:
- alcohol abuse
- liver infection
- liver cancer
- cirrhosis (scarring of the liver, usually due to
- gallstones (cholesterol stones made of hardened
fat material or pigment stones made of bilirubin)
- hepatitis (disease and swelling of the liver
that decreases its ability to function)
- pancreatic cancer
- parasites in the liver, which can block the
excretion or removal of bilirubin from the body
- blood disorders, such as hemolytic anemia (the
rupture or destruction of red blood cells that lead to a decreased amount of
red blood cells in your circulation, which leads to fatigue and weakness)
- an adverse reaction to or overdose of a
medication, such as an acetaminophen
Jaundice is also a frequent occurrence in
newborns, especially in babies who are born prematurely. An excess of bilirubin
may develop in newborns because their livers haven’t fully developed yet.
Your doctor will first conduct blood tests to
determine the cause of your jaundice. A blood test can not only determine the
total amount of bilirubin in your body, but it can also help detect indicators
of other diseases such as hepatitis.
Other diagnostic tests may be used, including:
- liver function tests: a series of blood tests
that measure levels of certain proteins and enzymes the liver produces when
it’s healthy and when it’s damaged
- complete blood count (CBC): to see if you have
any evidence of hemolytic anemia
- imaging studies: includes abdominal ultrasounds
(using high-frequency sound waves to generate images of your internal organs)
or CT scans
- liver biopsies: small samples of liver tissue
are removed for testing and microscopic examination
The severity of jaundice in newborns is generally
diagnosed with a blood test. A small blood sample is taken by pricking the
infant’s toe. Your pediatrician will recommend treatment if the results
indicate moderate to severe jaundice.
Again, jaundice itself is not a disease but it’s a
symptom of several possible underlying illnesses. The type of treatment your
doctor recommends for jaundice depends on the cause of your jaundice. Your
doctor will treat the cause of the jaundice, not the symptom itself. Once
treatment begins, your yellow skin will likely return to its normal state.
According to the American Liver Foundation,
most jaundice cases in infants resolve within one to two weeks.
Moderate jaundice is typically treated
with phototherapy in the hospital or in the home to help remove excess
The light waves used in phototherapy are absorbed
by your baby’s skin and blood. The light helps your baby’s body change the
bilirubin into waste products to be eliminated. Frequent bowel movements with
greenish stools are a common side effect of this therapy. This is just the
bilirubin exiting the body. Phototherapy may involve the use of a lighted pad,
which mimics natural sunlight and is placed on your baby’s skin.
Severe cases of jaundice are treated
with blood transfusions to remove bilirubin.
Jaundice usually clears up when the underlying
cause is treated. Outlook depends on your overall condition. See your doctor
right away as jaundice may be a sign of a serious illness. Mild cases of
jaundice in newborns tend to go away on their own without treatment, and cause
no lasting liver issues.
