<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 26y old. In 2008, I terminated my Pregnancy at that time doctor told.I am with Hep B deficiency. Is that dangerous. What problems do we face because of that.And I have a Lower Back to left Foot pain through Hip. When I do work out My leg feels heavy.  <response>: Hi, How are you? I am sure your doctor meant your He is low meaning your hemoglobin is low. Thisessentially means you have anemia which is very easily treated with nutritional supplements. Being deficient in Hep B is definitely good as this means you do not have hepatitis B infection. I would advise you to get vaccinated with hepatitis B vaccine to protect yourself against future risk of acquiring hepatitis B infection. Hoipe this helped and have a great day.
