Hi @Christianc2,
Thanks for sharing your story and asking these questions. As mentioned in other threads (Lifestyle changes, nutrition, and supplements for hep b) some supplements and herbal medicines (or other ingredients that are contained within them) can harm the liver and there is no evidence that they help to any clinically relevant degree. It might be worth seeing if abstaining from these can improve your status.
Otherwise, this really requires your doctor to do differential diagnosis and physical examinations to figure out what might be the cause of the hepatomegaly.
