What is hepatitis?

Also called: Viral hepatitis,

Hepatitis is inflammation of the liver. Inflammation is swelling that happens when tissues of the body are injured or infected. It can damage your liver. This swelling and damage can affect how well your liver functions.

Hepatitis can be an acute (short-term) infection or a chronic (long-term) infection. Some types of hepatitis cause only acute infections. Other types can cause both acute and chronic infections.

What causes hepatitis?

There are different types of hepatitis, with different causes:

How is viral hepatitis spread?

Hepatitis A and hepatitis E usually spread through contact with food or water that was contaminated with an infected person’s stool. You can also get hepatitis E by eating undercooked pork, deer, or shellfish.

Hepatitis B, hepatitis C, and hepatitis D spread through contact with the blood of someone who has the disease. Hepatitis B and D may also spread through contact with other body fluids. This can happen in many ways, such as sharing drug needles or having unprotected sex.

Who is at risk for hepatitis?

The risks are different for the different types of hepatitis. For example, with most of the viral types, your risk is higher if you have unprotected sex. People who drink a lot over long periods of time are at risk for alcoholic hepatitis.

What are the symptoms of hepatitis?

Some people with hepatitis do not have symptoms and do not know they are infected. If you do have symptoms, they may include

If you have an acute infection, your symptoms can start anywhere between 2 weeks to 6 months after you got infected. If you have a chronic infection, you may not have symptoms until many years later.

What other problems can hepatitis cause?

Chronic hepatitis can lead to complications such as cirrhosis (scarring of the liver), liver failure, and liver cancer. Early diagnosis and treatment of chronic hepatitis may prevent these complications.

How is hepatitis diagnosed?

To diagnose hepatitis, your health care provider

What are the treatments for hepatitis?

Treatment for hepatitis depends on which type you have and whether it is acute or chronic. Acute viral hepatitis often goes away on its own. To feel better, you may just need to rest and get enough fluids. But in some cases, it may be more serious. You might even need treatment in a hospital.

There are different medicines to treat the different chronic types of hepatitis. Possible other treatments may include surgery and other medical procedures. People who have alcoholic hepatitis need to stop drinking. If your chronic hepatitis leads to liver failure or liver cancer, you may need a liver transplant.

Can hepatitis be prevented?

There are different ways to prevent or lower your risk for hepatitis, depending on the type of hepatitis. For example, not drinking too much alcohol can prevent alcoholic hepatitis. There are vaccines to prevent hepatitis A and B. Autoimmune hepatitis cannot be prevented.

Hepatitis vaccine

What is an acute hepatitis?

Acute hepatitis is a term used to describe a wide variety of conditions characterized by acute inflammation of the hepatic parenchyma or injury to hepatocytes resulting in elevated liver function indices.

How is acute hepatitis diagnosed ?

Diagnosis is by liver function tests and serologic tests to identify the virus. Good hygiene and universal precautions can prevent acute viral hepatitis. Depending on the specific virus, preexposure and postexposure prophylaxis may be possible using vaccines or serum globulins.

What is the best medicine for hepatitis?

Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver. These drugs are taken by mouth. Talk to your doctor about which medication might be right for you.

Is acute hepatitis serious ?

But because more than half of the people with the acute infection go on to develop chronic infection, acute hepatitis C is serious. Acute hepatitis C can be treated, greatly reducing the risk of chronic infection. However, acute hepatitis C usually causes no symptoms, so diagnosis and treatment rarely occur.

What medical conditions cause hepatitis ?

The condition can be self-limiting or can progress to fibrosis (scarring), cirrhosis or liver cancer. Hepatitis viruses are the most common cause of hepatitis in the world but other infections, toxic substances (e.g. alcohol, certain drugs), and autoimmune diseases can also cause hepatitis.

Does hepatitis require surgery ?

If liver scarring, or cirrhosis, caused by viral hepatitis is so advanced that antiviral medication is ineffective, or if scarring has damaged the liver to such an extent that the organ is failing, NYU Langone specialists may recommend a liver transplant.

What are the complications of hepatitis ?

In general, complications of viral hepatitis may include the following:

Does hepatitis cause weight gain ?

Substantial weight gain is common after hepatitis C cure, an analysis of a large cohort shows, and around one in five people with normal body weight became overweight within two years, US Veterans Affairs researchers report in the Journal of General Internal Medicine.
