Hepatitis is a general term for inflammation of the liver. Normally, the liver breaks down waste products in your blood. But when the liver is inflamed, it doesn’t do a good job of getting rid of waste products. This causes waste products to build up in your blood and tissues.
Many different things can cause hepatitis. The most common cause of hepatitis is infection with one of the 5 hepatitis viruses (A, B, C, D, or E). Lack of blood supply to the liver, poisons, autoimmune disorders, excessive alcohol use, injury to the liver, and taking certain medicines can also cause hepatitis. Less commonly, viral infections such as mononucleosis or cytomegalovirus can cause hepatitis.
There are 2 main kinds of hepatitis: acute hepatitis (short-lived) and chronic hepatitis (lasting at least 6 months). Most people get over the acute inflammation in a few days or a few weeks. Sometimes, however, the inflammation doesn't go away. When the inflammation doesn't go away in 6 months, the person has chronic hepatitis.
Hepatitis C is a serious liver infection caused by the hepatitis C virus. It is spread from person to person through contact with blood. Most people who are infected with hepatitis C don't experience any symptoms for years. However, hepatitis C usually is a chronic illness (which means it doesn't go away). If you have hepatitis C, you need to be watched carefully by a doctor because it can lead to cirrhosis (scarring of the liver) and liver cancer. Cirrhosis from hepatitis C is a leading cause of liver failure and needing a liver transplant.
Many people don't feel sick or have symptoms of hepatitis C until they’ve had the virus for a long time. Some people have mild, flu-like symptoms anywhere from 2 weeks to 6 months after they are first infected with the virus. These symptoms may include:
As the disease progresses, hepatitis C can cause liver damage. In many cases, there are no symptoms until liver problems develop. If symptoms of liver problems do appear, they may include:
Hepatitis C is caused by infection with the hepatitis C virus. The virus is spread from person to person through contact with blood. People who use intravenous (IV) drugs can get hepatitis C when they share needles with someone who has the virus. Health care workers (such as nurses, lab technicians, and doctors) can get these infections if they are accidentally stuck with a needle that was used on an infected patient. You are also at a higher risk if you got a blood transfusion or an organ transplant before 1992 (improvements in blood-screening technology were made in 1992).
Hepatitis C can't be spread unless a person has direct contact with infected blood. This means a person who has hepatitis C can't pass the virus to others through casual contact such as sneezing, coughing, shaking hands, hugging, kissing, sharing eating utensils or drinking glasses, swimming in a pool, using public toilets, or touching doorknobs.
Hepatitis C is usually spread through direct contact with the blood of a person who has the disease. It can also be transmitted by needles used for tattooing or body piercing. In rare cases, hepatitis C can be passed from a mother to her unborn baby. This virus can be transmitted through sex, sharing razors or toothbrushes, although these occurrences are also rare. Many times, the cause of hepatitis C is never found.
Yes, once you have hepatitis C, you can always give it to someone else. If you have hepatitis C, you cannot donate blood. You should avoid sharing personal items like razors and toothbrushes, although it is very rare to pass hepatitis C in these ways. Always use a condom when you have sex. If you have hepatitis C, your sexual partners should be tested to see if they also have it.
Talk to your doctor first if you want to have children. The virus isn't spread easily from a mother to her unborn baby, but it is possible so you need to take precautions. However, if you're trying to have a baby, do not have sex during your menstrual cycle, because the hepatitis C virus spreads more easily in menstrual blood.
There is not yet a proven cure for hepatitis C, but it is noteworthy that after taking medicines for 6 months to 1 year, many people (45% to 75%) do not experience any more problems from hepatitis C. You should discuss treatment with a doctor if you have hepatitis C.
The standard method of treatment for hepatitis C is a combination of antiviral medicines. Your doctor will prescribe a full course of the medicines, then check the level of hepatitis C in your blood after you have completed the treatment. If there is still a significant amount of the virus in your system, your doctor may recommend another course of medicine.
Good health habits are essential for those who have hepatitis C, especially avoidance of alcohol and other medicines and drugs that can put stress on the liver. You should eat a healthy diet and start exercising regularly. Your family doctor can help you plan a diet that is healthy and practical.
Talk to your doctor about any medicines that you are taking, including over-the-counter medicine. Many medicines, including acetaminophen (brand name: Tylenol) are broken down by the liver and may increase the speed of liver damage. You should also limit alcohol use, as it also speeds the progression of liver diseases like hepatitis C. An occasional alcoholic drink may be okay, but check with your doctor first.
Side effects of treatment for hepatitis C may include the following:
Side effects are usually worst during the first few weeks of treatment and become less severe over time. If you are having trouble dealing with the side effects of your medicine, talk to your doctor. He or she can suggest ways to relieve some of the side effects. For example, if your medicine makes you feel nauseated, it may help to take it right before you go to sleep.
If taking medicine to treat hepatitis C makes you feel worse than the actual disease does, you may be tempted to stop taking your medicine before your treatment is done. However, if you don't prevent chronic inflammation from damaging your liver, you'll be much sicker in the long run. Don't stop taking your medicine until your doctor tells you to.
The choice is up to you and your doctor. The decision to use drug therapy can be hard to make because of the side effects. Your doctor will closely monitor your symptoms and the amount of the virus in your body. Your overall health and the results of your blood tests and the liver biopsy are also important factors to consider before you and your doctor start drug treatment for your hepatitis C.
The goal of treatment is to reduce the amount of the hepatitis C virus in your blood to levels that can't be detected after 24 weeks of therapy. The amount of the virus in your blood is called your viral load. At the end of your treatment, your doctor will need to measure your viral load and find out how healthy your liver is. He or she may repeat many of the same tests that were done when you were first diagnosed with hepatitis C.
If your blood has so few copies of the virus that tests can't measure them, the virus is said to be undetectable. If it stays undetectable for at least 6 months after your treatment is finished, you have what is called a sustained virologic response (SVR). People who have an SVR have a good chance of avoiding serious liver problems in the future.
If treatment doesn't reduce your viral load, or if you don't have an SVR after treatment, your doctor will discuss other treatment options with you. For example, if 1 round of treatment did not decrease your viral load enough, your doctor may recommend a second round of treatment. Even if treatment doesn't keep you from having active liver disease, lowering your viral load and controlling chronic liver inflammation may help you feel better for a longer time.
Coping with hepatitis C isn't easy. You may feel sad, scared or angry, or you may not believe you have the disease. These feelings are normal, but they shouldn't keep you from living your daily life. If they do— or if they last a long time— you may be suffering from depression. People who are depressed have most or all of the following symptoms nearly every day, all day, for 2 weeks or longer:
Talk to your doctor if you notice any of these symptoms. Your doctor can help by recommending a support group or a therapist, and/or by prescribing a medicine for you to take.
The only way to prevent hepatitis C is to avoid coming in contact with an infected person’s blood. Always have protected sex (use a condom). Don’t do intravenous (IV) drugs. Don’t share personal care items (such as razors or toothbrushes) with a person who has hepatitis C. If you’re a health care worker, follow your workplace’s standard safety practices.
No, there is no vaccine for hepatitis C. (There are vaccines for hepatitis A and hepatitis B.) If you have hepatitis C, your doctor may want you to get the hepatitis B vaccine (and maybe the hepatitis A vaccine, too), if you don't already have these viruses. If you have hepatitis C, you are more likely to catch hepatitis A or hepatitis B, which would cause more damage to your liver.
