Testing positive for HBsAg means you have the Hepatitis B virus, but having no symptoms is very common. You may not need immediate medication. Many people are inactive carriers who only require regular monitoring rather than treatment. To determine if you need antiviral medications (like tenofovir or entecavir), you should consult a hepatologist or gastroenterologist. They will recommend simple follow-up tests, including liver function tests and an HBV DNA viral load, to assess your liver health. For now, avoid alcohol, maintain a healthy lifestyle, and do not start any self-medication. Rest assured, this condition is highly manageable with proper medical guidance.
