In Hepatitis B, the liver is the main organ that is affected. The liver is responsible for cleaning the body from harmful substances, making bile to help digest food, and creating proteins that help the body function.
Acute hepatitis B is a medical condition that causes symptoms such as fatigue, loss of appetite, abdominal pain, vomiting, fever, and joint pain within 6 weeks of infection. It can also cause dark urine, pale stool, and yellowing of the skin and eyes. Infants and young children are more likely to have a non-jaundice or symptom-free infection. About 10% of acute hepatitis B infections can become chronic.
Chronic hepatitis B is an infection that lasts more than 6 months. It can cause long-term damage to the liver and can lead to serious health problems.
If your body has enough of a certain type of protective substance called antibodies, then you are naturally vaccinated against the hepatitis b virus and will recover fully. If your body does not have enough of these antibodies, then you will become a carrier of the virus, meaning you won't be sick but you can spread the virus to other people. After many years, the carrier may develop liver cancer or liver failure. If your body does not have enough antibodies, the virus will stay strong and can damage your liver, leading to liver failure or cancer over time.
About 2 billion people around the world have hepatitis B, which is one out of every three people. Of those 2 billion, 400 million have a long-term form of the disease. Every year, 1 million people die from complications related to hepatitis B.
