My hematologist/oncologist had me take OTC iron supplements the past 2-3 years because my hemoglobin levels were gradually declining sightly. I was diagnosed with smoldering multiple myeloma in April, 2010. It has remained smoldering. In fact, my labs have actually gotten better except for hemoglobin. Last month I began having severe nausea a few hours after taking a dose of iron. My dr advised me to discontinue iron. The nauseous feelings have continued. My pharmacist said iron could have caused a wound in my stomach that needs to heal. How is the best way to get it to heal? What foods might help healing and what are likely to cause more irritation?
