Hi, How are you? My name is Dr Suresh Raghavaiah. I am a Liver Transplant Surgeon and I hope to answer your question today. From the details you have provided, it would appear that your father is suffering from acute hepatits B infection. Most patients are carriers of hepatitis B and do not suffer from any ill effects. But in some patients the virus attacks the liver and leads to damage of the liver as evidenced by the elevated liver enzymes. Most often these acute episodes are self limiting and are easily treated with medications. But in the long run, it can lead to cirrhosis of the liver and the resulting complications may necessitate a liver transplant. In your dad s case, I would advise to continue with a low fat diet and take adequate nutrition. The hepamerz tablets work well to give the body adequate proteins. In addition I would look into treating the hepatitis B with medications as presence of active liver damage is one of the indications for anti-viral therapy. This will necessitate a blood test to look for the viral load. Please do ask your treating physician to order this test. Hope this helps and hope your Dad starts to feel better. Please do not hesitate to write back for further clarifications Have a great day Dr Suresh Raghavaiah
