What are the stages of chronic hepatitis B?
What are the stages of chronic hepatitis B?
The natural history of chronic hepatitis B infection can be divided into 4 phases: immune‐tolerant phase, immune‐active phase, immune‐control phase, and immune clearance. It is not uncommon to see a backward shift in phase and reactivation of disease from the immune clearance phase.
What can chronic hepatitis B lead to?
Having a chronic HBV infection can lead to serious complications, such as: Scarring of the liver (cirrhosis). The inflammation associated with a hepatitis B infection can lead to extensive liver scarring (cirrhosis), which may impair the liver’s ability to function. Liver cancer.
How fast does hepatitis B progress?
The incubation period of the hepatitis B virus ranges from 30 to 180 days. The virus may be detected within 30 to 60 days after infection and can persist and develop into chronic hepatitis B, especially when transmitted in infancy or childhood.
How long does hepatitis B take to damage the liver?
Seventy percent of carriers develop chronic persistent hepatitis B. Most do not appear to be ill. The remaining 30 percent of carriers experience continuous liver disease. This condition often progresses to cirrhosis and then, after 30 to 40 years, possibly to liver cancer.
How can hepatitis progress?
Progression begins with inflammation of the liver, followed by death of liver cells. This causes scarring and hardening of liver tissue. About 20 percent of people with chronic hepatitis C go on to develop cirrhosis of the liver in 15 to 20 years.
Is chronic hepatitis B serious?
Chronic hepatitis B can develop into a serious disease resulting in long-term health problems, including liver damage, liver failure, liver cancer, and even death. There were 1,649 deaths related to hepatitis B virus reported to CDC in 2018, but this is an underestimate.
How do I know if my hepatitis B is chronic?
People who test positive for the hepatitis B virus for more than six months (after their first blood test result) are diagnosed as having a chronic infection.
How can you tell if your liver is inflamed?

- Feelings of fatigue.
- Jaundice (a condition that causes your skin and the whites of your eyes to turn yellow)
- Feeling full quickly after a meal.
- Nausea.
- Vomiting.
- Pain in the abdomen.
Can chronic hepatitis B become inactive?
The inactive carrier state may for a lifetime, but a proportion of patients may undergo subsequent spontaneous or immunosuppressioninduced reactivation of HBV replication with reappearance of high levels of HBV DNA with or without HBeAg seroreversion and a rise in ALT levels [3].
Can you recover from chronic hepatitis B?
More than 9 out of 10 adults who get hepatitis B totally recover. However, about 1 in 20 people who get hepatitis B as adults become “carriers,” which means they have a chronic (long-lasting) hepatitis B infection. Carriers are more likely to pass hepatitis B to other people.
How long does it take for hepatitis to damage your liver?
After many years some people will have minimal liver damage with no scarring while others can progress to cirrhosis (extensive scarring of the liver) within less than ten years. On average it takes about twenty years for significant liver scarring to develop.
What is the best treatment for chronic hepatitis B?
Hepatitis B medications can help keep the virus under control and stop it damaging your liver, although they will not necessarily cure the infection and some people need lifelong treatment. The main medicines for chronic hepatitis B include peginterferon alfa 2-a and antiviral medicines.
