As few as 3 percent of Americans eligible to donate blood actually do — and fear and anxiety are common reasons why many just say no.
US hospitals are always in need of new donors; at Mayo Clinic, that need is heightened by concern about iron deficiency in frequent givers. The clinic, like many other health facilities, began requiring people to wait 12 weeks rather than eight between donations — a change in 2013 that meant an estimated 10 percent drop in its blood supply.
Common blood donation phobias
Do you regularly get hooked up to give blood? If not, you’re not alone. Here’s a look at 6 common blood donation phobias.
1) Fear of needles
Needles used in blood donation definitely aren’t the harpoons that needle-phobic people may think they are. Manish Gandhi, MD, medical director of the Mayo Clinic Blood Donor Center, says donors feel a pinprick, much like getting a vaccination.
“You can consider this like taking a flu shot, but at the same time, potentially you can help at least three people by one whole blood donation,” he says.
Dr Gandhi encourages those afraid of needles to put their fear to rest by visiting a blood donation center to see the needles being used.
2) Fear of the sight of blood
“You don’t have to see the blood,” Dr Gandhi says. “Our seats have TVs on them; you can watch a movie, you can watch a show while you are donating blood, so you don’t have to look at it.”
3) Fear of fainting
Donor centers take steps to prevent fainting. Few people faint, and research has shown that just because it happens once, that doesn’t mean it will again, Dr Gandhi says. “We are continuously looking at different ways that can be avoided.”
4) Fear of nausea
The fear of feeling sick to your stomach is easily avoided, Dr Gandhi says: “Eat a healthy breakfast or eat a full meal, keep yourself hydrated, and then come and donate blood. And don’t be thinking about ‘Oh, this is such a big needle,’ or the anxiety.
“Maybe a good idea would be to start thinking about a good song or watch a show, or do something. I think distraction is the key to successful donation.”
While eating before donating is important, it may be best to avoid a fatty meal such as a cheeseburger, fries and milkshake because it can actually change your plasma’s appearance. Plasma normally looks a bit like clear chicken broth; a fatty meal, and it looks more like gravy.
“It’s fine, it’s normal, but sometimes it’s not aesthetically pleasing to someone, so we don’t want plasma that is full of fat molecules,” says Dr Gandhi.
5) Fear that if you give once, the center will pester you to give again
Blood banks tend to respect donors’ privacy and how frequently they like to be called, Dr Gandhi says.
6) Fear giving blood will lead to a health problem
Potential donors are screened for health problems to make sure they are healthy enough to give. “In most cases, a healthy person — donating blood would probably do them good, because basically you are going to replenish new blood,” says Dr Gandhi.
To prevent the spread of HIV, hepatitis or other illnesses, disposable needles and blood donation sets are used, and fresh ones are used for each person, then disposed of, Dr Gandhi says. “So there’s no way you’re going to get a virus transmitted by blood, because you are not going to come into contact with someone else’s blood,” he says.
After giving, donors are asked to stay for 15 to 30 minutes and have something to eat and drink, Dr Gandhi says. They should avoid heavy exercise or lifting weight for the next six to 24 hours, but otherwise can return to normal activity, he says.
More blood donors are always needed
Mayo has found that roughly 45 percent of donors only give once or twice a year — if they give one more time, they will more than make up the 10 percent loss, Dr Gandhi says.
That shows that in addition to easing fears about blood donation, it is also important to address a common misconception: that there is plenty of blood on hand, and if a friend or family member needs it, there will be plenty of time to give blood then to help them.
“There’s always someone who needs it,” Dr Gandhi says. “Unfortunately, it’s always the sickest of people who need blood, and it’s the blood which makes a difference between life and death for them.”
