Hi Bappi kumar das, being HbsAg positive is not a diseased state but only informs you that you have been infected with Hepatitis B
virus. If you are asymptomatic you do not need treatment so no need to take any medication, however you should continue to have a healthy lifestyle as you already have now, if at all in the future you have any symptoms of hepatitis then you need to visit your doctor and take treatment for the same. As of now you can be relax and not worry about it . In the future when you plan to marry make sure that your would be bride is vaccinated 2 months prior to any sexual contact as she may get infected by you. It is also advisable not to donate blood and to inform your health care provider of your HbSag positive status. Take care and live healthy.
