Can blood donation be harmful to your health? Here’s what a new study found

Numerous people routinely contribute blood, but doing so significantly depletes their iron stores, which may take months to completely replenish — causing concern that benefactors may be living” on the edge of anemia,” Brittany Trang writes for STAT.

How blood donation can impact iron situations

According to Trang, a question that has” agonized the field of blood donation for as long as there have been transfusions” is whether giving blood may actually harm people.

In general, the body’s iron situations are tone- conserved since iron from old red blood cells is used to make new red blood cells. Unless a person loses blood, whether through period, injury, or donation, iron doesn’t leave the body.

Although a person’s body will replace bestowed blood volume within 24 hours, the same isn’t true for the volume of red blood cells, which could take months to replenish. For benefactors who are low in iron, the process of replacing the iron lost through donation may take over four months — indeed though benefactors are technically eligible to give blood every 56 days.

To make the arrestment position for donation, numerous regular blood benefactors will take iron supplements to make up their red blood cells just enough to meet the arrestment in time for their coming donation.

These benefactors” live on the edge of anemia so that they can contribute blood,” said Eldad Hod, an associate professor of pathology and cell biology and the vice president of laboratory drug at Columbia University Irving Medical Center.

How giving blood affects benefactors

To determine how benefactors are affected by blood donation, Tank and a platoon of experimenters conducted a study to follow frequent benefactors who were low in iron but not anemic.
In the study, actors bestowed blood, which was also screened for its transfusion quality and whether the benefactors were low in iron. In total, 79 actors who bestowed blood had low iron and were blindly randomized into two groups.

In one group, actors entered
intravenous iron to correct their iron insufficiency, and in the other group, actors entered a saline placebo. also, four to six months latterly, the actors were asked to contribute blood again and complete quality of life checks, as well as cognitive function assessments.
Overall, Hod and his platoon set up that there were no significant differences in transfusion quality, cognitive performance, or quality of life between actors who had their iron replenished and those who had not.

” The answer does not fit our prepossession, but is actually better for public health because it suggests that what we are doing isn’t harming our benefactors,” said Steven Spitalnik, administrative vice president for laboratory drug at Columbia’s department of pathology and cell biology and one of the study’s authors.
Although the experimenters set up that transfusion quality bettered after iron starvation for women under the age of 50, they said that it’s unclear whether this difference is clinically meaningful, and more study is demanded. specially, women under 50 are the group most likely to be turned down for blood donation because of low iron since they tend to lose iron through period.

The study experimenters noted that unborn studies should examine whether teenagers, who need advanced quantities of iron for development, are also affected by blood donation or if it’s dangerous to them because of their increased iron conditions.

In addition, health experts said that implicit benefactors who are linked as iron deficient shouldn’t just be told to take iron supplements. rather, workers at donation centers could take the occasion to encourage them to find a implicit underpinning cause for their insufficiency.

Overall, the study’s findings suggest that blood donation doesn’t harm benefactors and that fresh conditions for iron situations don’t need to be added to patron wireworks to insure safety.

” We do no detriment for people who give blood,” said Gary Brittenham, a professor of drug at Columbia and another author on the study,” but we are doing a great benefit to the people who need it.”
