Most people who are infected with hepatitis C—even people who have been infected for a while—usually don't have symptoms.

If symptoms do develop, they may include:

• Feeling very tired.
• Joint pain.
• Belly pain.
• Itchy skin.
• Sore muscles.
• Dark urine.
• Yellowish eyes and skin (jaundice, Opens dialog). Jaundice usually appears only after other symptoms have started to go away.

Most people go on to develop chronic hepatitis C but still don't have symptoms. This makes it common for people to have hepatitis C for 15 years or longer before it is diagnosed.

Some people who get hepatitis C have it for a short time (acute infection) and then get better.

But most people get long-term, or chronic, infection. This can lead to liver damage.

Long-term hepatitis C often causes tiny scars in your liver. If you have a lot of scars, it becomes hard for your liver to work well. Over time, some people have more serious problems such as cirrhosis, Opens dialog or liver cancer.

Some people who have hepatitis C don't notice a big difference in the way they feel. Others feel tired, sick, or depressed. Here are some steps you can take at home that may help you feel better both physically and emotionally.

• Slow down.

  It's very common to feel tired if you have hepatitis C. If you feel tired, give yourself permission to do less and rest more. If you can, ask others to help out around your home. Or ask your employer for a shorter or more flexible work schedule.

• Exercise.

  Be active if you feel up to it. Aerobic exercise can help you have more energy. It may also improve depression. Ask your doctor about your medicines and how they might affect your ability to exercise.

• Eat regular, nutritious meals.

  Sometimes people with hepatitis C have a hard time eating. You may have no appetite, feel nauseated, or have different tastes than you're used to. Even if you don't feel like eating, it's very important to eat small meals throughout the day. Some people have nausea in the afternoon. If this happens to you, try to eat a big, nutritious meal in the morning.

  If you have cirrhosis, it may not be a good idea to eat salty foods or foods that are high in protein. If you want to know more about which foods to avoid and which foods are good to eat, ask your doctor about meeting with a registered dietitian to discuss a healthy eating plan.

• Avoid alcohol and drugs.

  Your liver breaks down drugs and alcohol. If you have hepatitis C, one of the best things you can do is to avoid substances that may harm your liver, such as alcohol and illegal drugs. If you have cirrhosis, you also may need to avoid certain medicines.

  If you use illegal drugs or drink alcohol, it's important to stop. If you don't think you can talk openly with your doctor, you may want to find a doctor you feel better talking to. If you want to stop using drugs or alcohol and need help to do so, ask your doctor or someone else you trust about drug and alcohol treatment options.

  Many medicines can stress your liver. So talk to your doctor before you take any prescription or over-the-counter medicines. This includes herbal remedies too.

• Control itching.

  If you have itchy skin, talk to your doctor about medicines that you can use. Read and follow the instructions on the label.

• Seek help for depression.

  You may feel angry or depressed about having to live with hepatitis C. You may have a hard time knowing how to tell other people that you have the virus. It can be helpful to talk with a social worker or counselor about what having the disease means to you. You also may want to find a support group for people with hepatitis C. If you don't have a support group in your area, there are several online groups.

  Anyone who has a long-term illness can get depression. It also can be a side effect of antiviral medicines for hepatitis C. If you feel depressed, talk to your doctor about antidepressant medicines, counseling, or both.

• Learn about the disease.

  Learning about hepatitis C may help you feel more in control of it. The more you understand, the better you can make decisions about treatment and lifestyle changes that may help you feel better, both physically and emotionally.
