Topic Overview
What is cirrhosis?
Cirrhosis (say "suh-ROH-sus")
is a very serious condition in which scarring damages the
liver. The liver is a large organ that is part of the
digestive
system
. It does a wide range of complex jobs that are vital for life.
For example, the liver:
- Makes many important substances, including
bile to help digest food and
clotting factors to help stop bleeding.
-
Controls the amounts of sugar, protein, and fat in the
bloodstream.
- Stores important vitamins and minerals, including
iron.
- Filters poisons from the blood.
- Breaks down
(metabolizes) alcohol and many drugs.
When a person has cirrhosis, scar tissue (fibrosis
) replaces healthy tissue and prevents the
liver from working as it should. For example, the liver may stop producing
enough clotting factors, which can lead to bleeding and bruising. Bile and
poisons may build up in the blood. Scarring can also cause high blood pressure
in the vein that carries blood from the intestines through the liver (portal hypertension). This can lead to severe bleeding
in the digestive tract and other serious problems.
Cirrhosis can
be deadly. But early treatment can help stop damage to the liver.
What causes cirrhosis?
Cirrhosis can have many
causes. Some of the main ones include:
- Long-term, heavy use of alcohol. This is the
most common cause of cirrhosis in the United States. Alcoholic cirrhosis can
develop after 10 or more years of heavy drinking (5 or more drinks a day for a
man or 3 or more drinks a day for a woman).1 See

. - Chronic
viral hepatitis. Cirrhosis develops in about 10 to 20
out of 100 people with long-term (chronic) viral hepatitis (mainly hepatitis B
or C).2 Often it takes up to 20 years or longer
for cirrhosis to develop from hepatitis. It may happen much sooner in people
with viral hepatitis who drink a lot of alcohol.
- Autoimmune diseases, such as autoimmune hepatitis or
primary sclerosing cholangitis (PSC). In some people, the
immune system attacks the liver, causing inflammation
that leads to cirrhosis.
- Nonalcoholic
steatohepatitis (NASH). NASH is liver inflammation caused by a buildup
of fat in the liver. Although the cause is not known, NASH seems to be related
to some other conditions, including obesity, high
cholesterol and
triglycerides, and
diabetes.
- Blocked bile ducts. A disease
called primary biliary cirrhosis develops when the ducts that carry bile out of
the liver become inflamed and blocked. The exact cause is unknown, but it may
be related to a problem with the immune system.
- Inherited
diseases, such as
Wilson's disease,
cystic fibrosis, or
hemochromatosis. Cirrhosis can also be caused by a
condition called alpha1-antitrypsin deficiency, in which a protein collects in
the liver and causes damage.
Less common causes of cirrhosis include severe reactions
to medicines or long-term exposure to poisons, such as arsenic. Some people
have cirrhosis without an obvious cause.
What are the symptoms?
You may not have symptoms
in the early stages of cirrhosis. As it progresses, it can cause a number of
symptoms, including:
- Extreme tiredness and weakness.
- Nosebleeds and easy bruising.
- Weight
loss.
- Belly pain or discomfort.
- Yellowing of the skin
(jaundice).
- Itching.
- Fluid
buildup in the legs, called edema (say "ih-DEE-muh"), and in the belly, called
ascites (say "uh-SIGH-teez").
- Bleeding in the stomach or in the
esophagus, the tube that leads from the mouth to the stomach.
-
Confusion.
How is cirrhosis diagnosed?
The doctor will start
with a physical exam and questions about your symptoms and past health. If the
doctor suspects cirrhosis, you may have blood tests and imaging tests, such as
an
ultrasound or
CT scan. These tests can help your doctor find out
what is causing the liver damage and how severe it is.
To confirm
that you have cirrhosis, the doctor may do a
liver biopsy. This means he or she will use a needle
to take a sample of liver tissue for testing.
How is it treated?
It is important to get treated
for cirrhosis as soon as possible. Treatment cannot cure cirrhosis, but it can
sometimes prevent or delay further liver damage. Treatment may include
medicines, surgery, or other options, depending on what caused your cirrhosis
and what problems it is causing.
There are things you can do to
help limit the damage to your liver and control the symptoms:
- Do not drink any alcohol. If you don't stop
completely, liver damage may quickly get worse.
- Talk to your
doctor before you take any medicines. This includes both
prescription and over-the-counter drugs, vitamins, supplements, and herbs.
Drugs that can be dangerous include acetaminophen (such as Tylenol) and
anti-inflammatory drugs such as aspirin and ibuprofen (Advil or Motrin, for
example).
- Make sure your
immunizations are up-to-date. You are at higher risk
for infections.
- Follow a
low-sodium diet. This can help prevent fluid buildup,
a common problem in cirrhosis that can become life-threatening.
Symptoms may not appear until a problem is severe, so it
is important to see your doctor for regular checkups and lab tests. You may
also need testing to check for possible problems such as:
- Enlarged veins, called varices (say
"VAIR-uh-seez"), in the digestive tract. Varices can bleed.
- Liver
cancer. People with cirrhosis are at higher risk for liver cancer.
If cirrhosis becomes life-threatening, then
liver transplant may be an option. But transplant is
expensive, organs are hard to find, and it doesn't always work. For these
reasons, doctors have to decide who would get the most benefit from a liver
transplant. Ask your doctor what steps you can take now to improve your overall
health so you can be a good candidate for transplant.
If your
cirrhosis is getting worse, you may choose to get care that focuses on your
comfort and dignity.
Palliative care can provide support and symptom relief
so you can make the most of the time you have left. You may also want to make
important end-of-life decisions, such as writing a
living will. It can be comforting to know that you
will get the type of care you want.
It can be hard to face having
cirrhosis. If you feel very sad or hopeless, be sure to tell your doctor. You
may be able to get counseling or other types of help. Think about joining a
support group. Talking with other people who have cirrhosis can be a big
help.
