Thank you for posting query at HCM. HBsAg positive without further evaluation can not be adviced treatment. your friend also needs to check his liver enzymes (LFT), HBeAg , and viral load (PCR test). Results of all these together with HBsAg will give a clear picture for treatment. It is possible that the virus remains in dormant phase throughout and causes no harm to liver. Only one fourth of patients infected with HepB virus develop liver cirrhosis. therefore, one cannot be sure about your friend status. the viral load should be monitored and he needs to repeat test every 6 month or atleast once a year. meanwhile, people close to your friend needs vaccinated and also test for HBsAg. advice for friend:(if increased liver enymes) abstinence from Alcohol and drugs - LOW fat diet should be followed - NO red meat - vegetables should be ingested daily - Moreover, less activity should be carried out (no sports). - use lemon juice (lemonade) once in a day - walk 30 to 40 minutes everyday. - or swimming is alternative to walking - NO sports and NO jogging - recheck liver enzymes after 6 to 8 weeks . if any further questions, feel free to ask. Health professionals aim to diagnose properly and manage patients according to their limited knowledge. Cure is blessed by the ONE who Created us, whose power and knowledge is unlimited . wish you good health. regards, Dr Tayyab Malik
