Hepatitis is an inflammation of the liver. It may be caused by drugs, alcohol use, or certain medical conditions. But in most cases, it's caused by a virus. This is known as viral hepatitis, and the most common forms are hepatitis A, B, and C.

Hepatitis Symptoms

Sometimes there are no symptoms of hepatitis in the first weeks after infection -- the acute phase. But when they happen, the symptoms of types A, B, and C may include fatigue, nausea, poor appetite, belly pain, a mild fever, or yellow skin or eyes (jaundice). When hepatitis B and C become chronic, they may cause no symptoms for years. By the time there are any warning signs, the liver may already be damaged.

Hepatitis A: What Happens

Hepatitis A is highly contagious and can spread from person to person in many different settings. It typically causes only a mild illness, and many people who are infected may never realize they're sick at all. The virus almost always goes away on its own and does not cause long-term liver damage.

Hepatitis A: How Does It Spread?

It usually spreads through food or water. Food can be tainted when it's touched by a person with hepatitis who did not wash his hands after using the bathroom. This transfers tiny amounts of infected stool to the food. Raw shellfish, fruits, vegetables, and undercooked foods are common culprits in hepatitis A outbreaks. The virus can also spread in daycare centers if employees aren't careful about washing hands after changing diapers

Hepatitis B: What Happens

Many adults who get hepatitis B have mild symptoms for a short time and then get better on their own. But some people are not able to clear the virus from the body, which causes a long-term infection. Nearly 90% of infants who get the virus will carry it for life. Over time, hepatitis B can lead to serious problems, such as liver damage, liver failure, and liver cancer.

Hepatitis B: How Does It Spread?

You can get it through contact with the blood or body fluids of an infected person. In the U.S., it's most often spread through unprotected sex. It's also possible to get hepatitis B by sharing an infected person's needles, razors, or toothbrush. And an infected mother can pass the virus to her baby during childbirth. Hepatitis B is not spread by hugging, sharing food, or coughing.

Hepatitis C: What Happens

About 25% of people who get hepatitis C defeat the virus after a short-term infection. The rest will carry the virus in their body for the long term. Chronic hepatitis C can cause very serious complications, including liver failure and liver cancer. There are effective treatments for the virus, though.

Hepatitis C: How Does It Spread?

It spreads through infected blood. In the U.S., sharing needles or other items used to inject drugs is the most common cause of infection. Getting a tattoo or body piercing with an infected needle is another means of exposure. A mother may pass the virus to her child at birth. In rare cases, unprotected sex spreads hepatitis C, but the risk appears small. Having multiple sex partners, HIV, or rough sex seems to raise risk for spreading hepatitis C.

How Is Hepatitis Diagnosed?

Chronic hepatitis can quietly attack the liver for years without causing any symptoms. Unless the infection is diagnosed, monitored, and treated, many of these people will eventually have serious liver damage. Fortunately, blood tests can determine whether you have viral hepatitis, and if so, which kind.

Treatment: Hepatitis A

Hepatitis A almost always goes away on its own, and no medication is needed. If nausea is a problem, try eating several small meals throughout the day instead of three large ones. Drink water, juice, or sports drinks to stay hydrated. And avoid hard exercise until you're feeling better.

Treatment: Chronic Hepatitis B

The goal of treating chronic hepatitis B is to control the virus and keep it from damaging the liver. This begins with regular monitoring for signs of liver disease. Antiviral medications may help, but not everyone can take them or needs to be on medication. Be sure to discuss the risks and benefits of antiviral therapy with your doctor.
