Hepatitis B Carriers: Risks and Family History Explained

Hepatitis B

Dear Doctor, hello! What exactly is a "hepatitis B carrier"? Both of my parents died of liver cancer, and my mother seems to be a carrier of hepatitis B.
Does this mean I am at a higher risk of getting it? Also, my lifestyle is not very good, as I tend to sleep late.
Thank you for your response!

Hello! In Taiwan, there are approximately three million carriers of hepatitis B.
The term "hepatitis B carrier" refers to individuals who have the hepatitis B surface antigen (HBsAg), which typically does not disappear throughout their lifetime.
Hepatitis B patients can be divided into three groups: first, healthy carriers (with normal liver function and no active virus); second, those with chronic hepatitis; and third, individuals with cirrhosis.
The latter two groups have a higher risk of developing liver cancer in the future and require management, while the first group is almost indistinguishable from healthy individuals and only needs to be monitored annually.
If a mother is a hepatitis B patient and HBsAg remains positive, there is about a 90% chance of transmission to her child during delivery.
Therefore, if the mother is a hepatitis B carrier, the child must undergo a blood test to determine if they have hepatitis B.
If the mother is a healthy carrier, no medication is necessary; maintaining a normal daily routine and getting adequate sleep is sufficient.
Sincerely, Dr.
Yang Pei-Chen, Director of the Gastroenterology Department at Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Hepatitis B is a viral infection that affects the liver and can lead to both acute and chronic diseases. A "Hepatitis B carrier" refers to an individual who is chronically infected with the Hepatitis B virus (HBV) and carries the Hepatitis B surface antigen (HBsAg) in their blood for six months or longer. This status indicates that the virus is still present in their body, and they may be infectious to others.

In your case, having a family history of Hepatitis B, particularly with your mother being a carrier, does increase your risk of being infected with the virus, especially if she was positive for HBsAg during pregnancy. The transmission can occur from mother to child during childbirth, which is a common route of infection in areas with high rates of Hepatitis B. However, it is important to note that not everyone born to a Hepatitis B carrier will become infected; it depends on various factors, including the mother's viral load and whether appropriate preventive measures were taken at birth.

Regarding your concern about your lifestyle, while poor sleep habits and stress can negatively impact your overall health, they do not directly cause Hepatitis B infection. However, maintaining a healthy lifestyle is crucial for individuals who are carriers or at risk of liver diseases. A balanced diet, regular exercise, and adequate sleep can help support liver health and overall well-being.

As for the severity of Hepatitis B, it varies among individuals. Some people may remain asymptomatic and live healthy lives as "healthy carriers," while others may develop chronic liver conditions such as chronic hepatitis, cirrhosis, or even liver cancer over time. Given your family history of liver cancer, it is essential to monitor your liver health regularly. This typically involves routine blood tests to check liver function and imaging studies like ultrasounds to assess liver structure.

If you are concerned about your risk of Hepatitis B, it is advisable to get tested for HBsAg and other related markers, such as antibodies to Hepatitis B surface antigen (anti-HBs) and Hepatitis B e antigen (HBeAg). These tests will help determine your infection status and whether you need further evaluation or treatment.

In terms of prevention, vaccination against Hepatitis B is highly effective and can protect you from the virus. If you are not already vaccinated, consider discussing this with your healthcare provider. Additionally, practicing safe behaviors, such as avoiding sharing needles or engaging in unprotected sex, can help reduce the risk of transmission.

In summary, being a Hepatitis B carrier or having a family history of the disease does increase your risk, but it does not guarantee that you will develop the infection. Regular monitoring and maintaining a healthy lifestyle are key to managing your health. If you have any further concerns, please consult with a healthcare professional who can provide personalized advice and support.
