My iron is low. Hemoglobin low side of normal, ferritin 7, saturation 9%. Dr suggested iron ivs. Is this safe? Risks side effects and chances of thwm.

It's your call: I think they're safe enough, the chances of serious harm from them is low, and you'll feel better faster. Some folks do get sickish during the infusion. I do trust that a cause for your iron deficiency has been sought adequately -- I've seen colon cancer missed in a woman in her 20's with fatal results. If you're deficient due to monthy loss, talk about supplements; if from reflux, Rx'ing this. ...Read more

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

Can you tell me what is the best supplement for low ferritin level?

Can you tell me what is the best supplement for low ferritin level?

Find out why: You need to find out why you are iron deficient. Unless you're a young woman with heavy monthly losses, or are on an iron-poor diet (most vegetarians do need to supplement), you have stomach or colon cancer until proved otherwise. Red meat or ferrous gluconate / sulfate tablets will both supply iron, but first find out what's really going on. Best wishes. ...Read more

The level of ferritin for my daughter that age 14 years is 7.49 ng/ml in the time where she is taking iron supplement from 3 years. What's the solut?

The level of ferritin for my daughter that age 14 years is 7.49 ng/ml in the time where she is taking iron supplement from 3 years. What's the solut?

Consider Specialist: 14 yr old on "iron supplement x 3 yrs", "ferritin = 7.49 ng/ml". Ferritin < 10 ng/ml indicates an absence of iron stores. This can result from many disease states, most commonly chronic blood loss (for ex. Heavy menstrual bleeding), & chronic illnesses. No other lab data was given. Diagnosis can be challenging. See your doctor for further evaluation, consider referral to Hematology specialist. ...Read more

Foundout my iron is 31, ferritin is 5.Really worried. I bleed heavily 2 of 5 period days. Is that enough to cause this? I feel fine+started supplements.

Yes: You are iron-deficient. You are wise to be on supplements. Iron deficiency is common in mentruating women due the monthly blood loss. Continue the iron for a couple of months at least and, if your periods are abnormal, consult with your ob-gyn. O/w just take iron. This is common. Don't be worried. ...Read more

Dx and treated B12 def with lvl of 78 five yrs ago, but now ferritin 13 (12-250ug/l) and folate (folic acid) 6.3 (4-20ug/l), should these levels b supplemented?

Iron: There is certainly no harm in supplementing your folate (folic acid) (must continue your b12!) but that level seems fine. Your ferritin level seems low and most likely indicates that there is not enough iron in your system. This too can lead to anemia. Iron supplements seem indicated. You should see your doctor to fully evaluated why your ferritin is low. ...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
