Iron Supplements (Definition)

Effective treatment for anemia is generally taking an iron supplement by mouth. Iron pills are large and difficult for some women to swallow. If so, you can usually break them in half and have one half with breakfast and the other with lunch. Drink a lot of water and eat foods that are high in fiber as iron can be constipating. You doctor may also prescribe ...Read more

Follow it: It's important to remember that the lab's "reference range" isn't the "normal range" or the "heathy range". Reference range is set so that 5% of perfectly healthy people fall outside. Real disease announces itself by marked variances from these ranges, or by symptoms supported by labs. Consider yourself healthy. ...Read more

If I'm anemic can I still donate blood if I don't take iron pills and if I'm on kidney medication?

If I'm anemic can I still donate blood if I don't take iron pills and if I'm on kidney medication?

No: Only in a special situation where an anemic person's blood is urgently needed would anyone want to take an anemic person's blood donation... because it would make the donor even more anemic. Perhaps if an anemic person were the only matching donor remaining in town, and a tranfusion was emergently needed... but that situation should not happen anywhere in modern America. ...Read more

I fainted last week &now am having headaches. I had blood test done and found out I'm anemic so I got iron pills. But why am I still having headaches?

Good question to ask: Your doctor! Find out how anemic you are, and how low your iron is, and see if your urine production/ urinalysis was normal. This may explain it, and if you are dehydrated, you may be having headaches, and this is best answered by your doctor, who knows you! ...Read more

Mom is high in ferratin, had hematoma on theigh from angio for her heart, used iron pills for low blood, now hemoglobine is normal but high ferratin?

High ferritin: Ferrtin is the body storage of reserve iron. If iron gets to low then iron deficiency anemia occurs because iron is necessary to make hemoglobin. When oral iron is taken then when absorbed it raises the storage iron of ferritin. Consult your doctor to see about modifying the dose of iron if the serum ferritin gets to high. ...Read more

What Foods apart from taking iron pills will give me blood quickly? And how often shld I exercise? I'm anemic due to Fibroids. Clots are like an Egg.

Treat the cause: The cause of your anemia appears to be blood loss due to the fibroids. This leads to iron deficiency which you are trying to correct. But it is playing catch up and may not succeed. So you need to get treatment for the fibroids...ask your gynecologist how to fix up the source of bleeding. No other diet will help you. ...Read more

Doctor my anemia is due to red blood cells destruction & any iron pills not affected in my case so what can I do to increase the number & size of this?

Depends...: Anemia due due red cell destruction does not improve with iron. If cause is immune system, prednisone may help. If cause is abnormal shape of RBCs, then SEVERE cases may benefit from splenectomy. Your hematologist is best positioned to advise you.

If you have thalassemia (causes small RBCs) folic acid helps a little, but there is no fundamentally effective treatment. ...Read more

Talk to your PCP: If you are 50 you are due for a screening colonoscopy. Your PCP should be able to hand you guaiac strips to check your stool. Do not take any over the counter meds- specifically Advil, Motrin, Aleve (naproxen). Hope it helps. ...Read more

Is it possible to have a low blood iron with a normal blood count?

Is it possible to have a low blood iron with a normal blood count?

Probably not: If a cbc, complete blood count, is completely normal then iron levels are probably normal as well. A low iron level could initially be noted as a low MCV (which means the red cells are small). This could occur before the hemoglobin or hematocrit decrease. If the test you took was just a hemoglobin or hematocrit, see your doctor to get a cbc. ...Read more

My blood count was 7.54. Dr put me on iron and vit B complex. Is this enough? Should I be more worried and doing more?

Probably: A hemoglobin level of 7.54 suggests a severe anemia. In young women, mild anemia can at times be from excess menstruation and treated with iron alone, however with more severe anemia the cause should be understood and corrected. Your doctor should know more about the cause in this situation and the plan to correct it, and it would be appropriate to ask about this. ...Read more

How effective is iron infusion in raising blood count? How soon can one expect to see improvement?

How effective is iron infusion in raising blood count? How soon can one expect to see improvement?

Several weeks: If you have anemia due to low iron, increasing your iron level will help in the production of new red cells but it takes time for the bone marrow to release these cells. Normally red cells live for 120 days, bone marrow can increase the production if needed as in case of anemia due to iron deficiency, but only after iron is available. From that time it may take 2-4 weeks to start improving. ...Read more

If I taking iron supplements for one year, and missed them for one week, would it show a large discrepancy if I have blood work done?

If I taking iron supplements for one year, and missed them for one week, would it show a large discrepancy if I have blood work done?

No: Missing one week of iron, after taking them for a whole year would make very little difference in any lab test. Your body stores the iron, and if you are anemic it takes time for the red blood cells to be produced, so missing just a week will not make a noticeable difference. ...Read more

Anemia is. ....: An hematocrit outside the normative values for age and sex. Its presence can be detected by a complete blood count (cbc).

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?

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
