Hepatitis
Hepatitis is inflammation of the liver. When the liver is inflamed or damaged, it may not work as effectively. Because the liver helps filter waste, process nutrients and medications, and support many important body functions, ongoing inflammation can lead to more serious liver problems over time.
Key Takeaways
- Hepatitis means inflammation of the liver.
- Some forms are caused by viruses, while others may be related to alcohol use, medications, toxins, or autoimmune disease.
- Common viral types include hepatitis A, hepatitis B, and hepatitis C.
- Untreated hepatitis can sometimes lead to scarring, cirrhosis, liver failure, or liver cancer.
Common Types of Hepatitis
There are several forms of hepatitis, and the cause helps determine treatment and prognosis.
- Hepatitis A is usually a short-term infection and is often spread through contaminated food, drink, or close contact.
- Hepatitis B spreads through blood or bodily fluids and may be acute or chronic.
- Hepatitis C often has few or no symptoms early on but can become chronic if not treated.
- Other forms of hepatitis may be related to alcohol use, medications, toxins, fatty liver disease, or autoimmune conditions.
Symptoms of Hepatitis
Some people with hepatitis have no symptoms, especially early in the course of disease. When symptoms are present, they may include:
- Fatigue
- Loss of appetite
- Nausea or vomiting
- Abdominal discomfort
- Fever
- Dark urine
- Clay-colored stools
- Joint pain
- Yellowing of the skin or eyes (jaundice)
How Hepatitis Spreads or Develops
Not all hepatitis is caused by infection. Viral hepatitis is caused by a virus, but liver inflammation can also result from heavy alcohol use, some medications, toxins, or certain medical conditions. Each type of viral hepatitis spreads differently.
How Hepatitis Is Diagnosed
Diagnosis may include a review of symptoms and medical history, physical examination, blood tests, and imaging. In some cases, additional evaluation such as a liver biopsy may be recommended depending on the cause and severity of liver disease.
Treatment Options
Treatment depends on the type and cause of hepatitis. Some forms improve with supportive care, while others require long-term monitoring or medication. For example, vaccines can prevent hepatitis A and hepatitis B, and hepatitis C can often be cured with oral medication.
- Monitoring liver function
- Treating the underlying cause
- Antiviral treatment in select cases
- Avoiding alcohol and other liver irritants when appropriate
- Managing complications if liver damage is present
Possible Complications
If hepatitis continues unchecked, it can lead to liver scarring (fibrosis), cirrhosis, liver failure, or liver cancer in some patients. Early diagnosis and follow-up are important.
When to Seek Medical Care
You should seek evaluation if you have jaundice, ongoing fatigue, unexplained nausea, dark urine, abdominal pain, abnormal liver tests, or known risk factors for hepatitis. It is also important to seek care if you believe you may have been exposed to viral hepatitis.
Frequently Asked Questions
What is hepatitis?
Hepatitis is inflammation of the liver. It can interfere with the liver’s ability to perform important functions.

Yes. Some people do not have symptoms, especially early on, which is one reason testing can be important.
What are common symptoms of hepatitis?
Common symptoms may include fatigue, nausea, abdominal discomfort, dark urine, light-colored stools, and jaundice.
Can hepatitis lead to cirrhosis?
Yes. Ongoing inflammation from some forms of hepatitis can lead to liver scarring and cirrhosis over time.
How is hepatitis treated?
Treatment depends on the cause. Some forms improve with supportive care, while others may require antiviral medication, long-term monitoring, or treatment of complications.
