Hypergammaglobulinemia means increased globulin levels in blood. This can happen because of a blood cancer called as multiple myeloma. But good news is that, you are not having that cancer. This is what unspecified means. Iron is needed for hemoglobin synthesis. Whenever one consumes less of iron or there loss of iron due to chronic blood loss, hemoglobin level reduces below normal. We call this condition as iron deficiency anemia. So obviously, when supplemental iron is given in the form of tablets, hemoglobin level increases to normal level. If there is associated vitamin deficiency, those vitamins also need to be substituted. That is exactly what is being done to you. Hope I have answered your question. If you have any further questions I will be happy to help. With regards, Dr. Girish Kamat
