Macrophages are cells that contain large amounts of ferritin, and this that helps them scavenge RBC at sites of old hemorrhage. High serum ferritin levels occurs from macrophage activation and is a ...Read more

Taking iron supplements, my ferritin is very low (5), my tranferrin and iron are normal. My TIBC and % transferrin saturation are high. Cause?

Taking iron supplements, my ferritin is very low (5), my tranferrin and iron are normal. My TIBC and % transferrin saturation are high. Cause?

Partially treated: Ferritin reflects body storage iron, while serum iron and transferrin saturation reflect current iron circulating in plasma. When you take oral iron supplement, the amount of iron in circulation (absorbed from gut on its way to storage sites) is transiently high. Your data suggest you have iron deficiency, partially treated, with blood tests taken within a day or two of your most recent iron pill. ...Read more

I have Polycythemia Vera and after my last phlebotomy my Ferritin level went down to 6. Is that severe? Should I take iron supplements?

That's fine: That's actually what you want, if you've really got polycythemia vera. Now I'm concerned about something. You say you're only 29. At your age, true polycythemia vera would be almost unheard-of. Is the diagnosis correct? Has it been demonstrated by today's molecular biology? It is possible that you have a high-affinity hemoglobin or a right-to-left shunt? Just wondering. ...Read more

Serrum ferritin is increasing but at a slow pace after taking iron supplements for 5 monts then why hair fall has started again when it stopped earier?

Serrum ferritin is increasing but at a slow pace after taking iron supplements for 5 monts then why hair fall has started again when it stopped earier?

Cause important: Simple iron deficiency should correct within 3 months of starting replacement. If there is no improvement or a slow response the cause of the iron deficiency matters. If there is ongoing blood loss the improvement will be delayed or absent. How you take iron matters--better absorption on empty stomach but maybe more side effects. Iron malabsorption is a rare possibility. Discuss with your doctor. ...Read more

Can you raise ferritin levels with high iron diet alone? OR is it similar to vitamin D in that it takes supplements and months to bring up?

Can you raise ferritin levels with high iron diet alone? OR is it similar to vitamin D in that it takes supplements and months to bring up?

Depends: If you have iron deficiency anemia, it will take months with oral iron supplements. Menstruating women are not uncommonly iron deficient and it would be prudent to take oral iron and multivitamins.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Been taking iron supplements for 5 weeks, Hb increased from 9.8 to 11.7. Blood tests came back fine except RDW (27.8)being high. Should I discontinue?

Probably. Best also: Check serum Fe+2, Total Iron Binding Capacity & Ferritin as indicators of degree of adequacy of iron replacement. While too much iron over time is toxic, you also want enough intake to replace iron in RBCs lost via bleeding. Normally iron in RBCs is recycled back to bone marrow; can't do this if RBCs are lost outside body. High RDW expected due to mix of small RBCs (when Fe low) vs. Normal RBCs. ...Read more
