Liver damage may not cause any symptoms in the early stages. The first signs may be nonspecific, such as nausea or fatigue. Later stages may cause worsening symptoms, such as jaundice, itchy skin, and swelling of the lower extremities. Liver damage has many potential causes, including viruses, obesity, and alcohol abuse.
Over time, the damage leads to a buildup of scar tissue on the liver, known as cirrhosis. When this happens, scar tissue replaces healthy liver tissue, leading to symptoms and eventually liver failure. A person may have no initial symptoms. As the damage progresses, a person may begin to notice nonspecific symptoms that may gradually get worse.
This article reviews the early and late symptoms of liver damage, their causes, treatment and prevention.
Early signs
Liver damage has a variety of potential causes, including alcohol consumption and viral infections. At first, these conditions may not cause any symptoms. As the damage worsens, a person may begin to notice new symptoms developing.
Early signs of liver damage and scarring may include:
loss of appetite
fatigue
nausea
discomfort or slight pain in the upper right part of the abdomen
unexplained weight loss
vomiting
A person may not have all of these symptoms.
These are also nonspecific symptoms, meaning they can be due to several potential causes other than liver damage.
Later signs
As liver damage and scarring progress, symptoms may worsen.
They may include:
a yellowish tint to the eyes or skin: jaundice
easy bleeding or bruising
severe itching of the skin
swelling of the legs, ankles, or feet (edema)
difficulty thinking, confusion, memory loss, personality changes or trouble sleeping
a buildup of fluid in the abdomen – ascites
dark colored urine

Causes
Liver damage can be due to different causes. They may include:
alcohol abuse
viral infections, such as hepatitis B or hepatitis C
obesity
diseases that block or damage the bile ducts
long-term use of certain medications
chronic heart failure
genetic liver diseases, such as Wilson’s disease
autoimmune hepatitis
These conditions can cause liver damage and scar tissue, known as cirrhosis. When a person has cirrhosis, their liver does not heal and scar tissue begins to replace healthy tissue.
This can lead to complications, such as
portal hypertension, where scar tissue partially blocks and slows blood flow in the liver
liver cancer
infections
Hepatic insufficiency

Treatment
Treatment for cirrhosis generally focuses on correcting the underlying condition. In some cases, a healthcare professional may be able to cure the underlying condition.
However, aside from a liver transplant, there is no treatment for cirrhosis. Treating the underlying causes can help prevent further damage and possibly help the person avoid liver failure.
Treatments for underlying causes often involve the use of medications and other therapies. Therapies for specific conditions may include:
Nonalcoholic fatty liver disease: Weight loss through diet and exercise.
Chronic hepatitis B: Treatment includes antiviral medications.
Chronic hepatitis C: Approved drugs that treat hepatitis C.
Alcoholic liver disease: Stopping alcohol consumption and attending alcoholic support groups.
Autoimmune hepatitis: Using medications to help suppress the immune system.
Long-term use of certain medications: Stop or replace the medication causing the damage.
Bile duct diseases: Medicines or surgery (to further open the bile ducts).
Hereditary liver diseases: These treatments may vary depending on the disease.
A person should work with a doctor or healthcare team to determine the best treatment options for them.
Prevention
It is not always possible to prevent all causes of liver damage, but steps can be taken to reduce the risk and prevent cirrhosis from getting worse.
Here are some tips to help prevent liver damage:
limit alcohol consumption
discuss dietary supplements with a healthcare professional before taking them
avoid illegal drugs
discussing medications with a healthcare professional before taking them, whether prescription or over-the-counter (OTC) medications
take medications as directed
avoid raw or undercooked shellfish, fish and meat
get tested for hepatitis C
maintain a moderate body weight
have a balanced diet
get vaccinated against
hepatitis A
hepatitis B
influenza
pneumonia caused by certain bacteria

When to contact a doctor
People should see a healthcare professional if they have symptoms that last more than a few days and could indicate liver damage. People with cirrhosis who need to change medications or are considering taking over-the-counter medications or dietary supplements should also consult a healthcare professional. This can give advice on the safety of taking medications and food supplements in the event of cirrhosis.
Résumé
Liver diseases that cause damage often do not show obvious signs or symptoms until the liver is damaged. At first, symptoms may be mild and include weight loss, fatigue, or nausea. As the lesions progress, the person’s symptoms also begin to worsen. She may develop jaundice, bruise easily, and develop swelling of the lower extremities. Treatment usually focuses on correcting the underlying condition.
In some cases, treatment can cure the condition. In others, it may help slow the progression of liver damage. Maintaining a moderate weight, limiting alcohol consumption and treating underlying conditions, such as hepatitis C, can help prevent liver damage.
