RULES (updated 01/22/25)

  1. Be respectful: no harassment, hate speech, bigotry, and/or trolling. To be concise, disrespect is defined by escalation.
  2. Encourage conversation in your OP. This means including heavily implicative subject matter when you can and also engaging in your thread when possible. You won't be punished for trying.
  3. Avoid controversial topics (politics or societal debates come to mind, though we are not saying not to talk about anything that resembles these). There's a guide in the protocol book offered as a mod model that can be used for that; it's vague until you realize it was made for things like the rule in question. At least four purple answers must apply to a "controversial" message for it to be allowed.
  4. Keep it clean and SFW: No illegal content or anything gross and inappropriate. A rule of thumb is if a recording of a conversation put on another platform would get someone a COPPA violation response, that exact exchange should be avoided when possible.
  5. No solicitation such as ads, promotional content, spam, surveys etc. The chart redirected to above applies to spam material as well, which is one of the reasons its wording is vague, as it applies to a few things. Again, a "spammy" message must be applicable to four purple answers before it's allowed.
  6. Respect privacy as well as truth: Don’t ask for or share any personal information or slander anyone. A rule of thumb is if something is enough info to go by that it "would be a copyright violation if the info was art" as another group put it, or that it alone can be used to narrow someone down to 150 physical humans (Dunbar's Number) or less, it's considered an excess breach of privacy. Slander is defined by intentional utilitarian misguidance at the expense (positive or negative) of a sentient entity. This often links back to or mixes with rule one, which implies, for example, that even something that is true can still amount to what slander is trying to achieve, and that will be looked down upon.

I tried once. But they said they couldn't take it in a bucket and wouldn't stop asking where I got it from.

Bender: I'm very generous! What about that time I gave blood?

Fry: Whose blood?

Bender: Some guy's.

[–] Grimy@lemmy.world 5 points 3 weeks ago

The only thing I can tell you is that based on how much blood is in this bucket, you are in desperate need of blood.

[–] CAVOK@lemmy.world 19 points 3 weeks ago

I do. I donate as often as I'm allowed, which is about 4 times a year. The only effect I've felt is that exercise, especially cardio, is a bit harder. My time on a 5k run dropped noticeably.

Donated 60 times in total so far, which means there's more of my blood in other people, than in me. By quite a lot.

[–] v4ld1z@lemmy.zip 11 points 3 weeks ago

Financial incentive plus I have a blood group that's beneficial to patients

Once around every 2ish to 3 months - essentially however often I'm allowed to

Usually good. Don't feel dizzy or sick afterwards since I eat and drink well before donating.

I do donate plasma quite regularly too - around once a week - but have not four a couple months now since I got a new tattoo in November. For similar reasons as with blood donations

[–] noxypaws@pawb.social 11 points 3 weeks ago (1 children)

Most of my life I've not been allowed to donate blood because I'm a man who has sex with men. I believe I can now, but after decades of ineligibility it still feels weird to think about.

[–] bunnyBoy@pawb.social 8 points 3 weeks ago

You are now eligible, they recently removed the requirement. It's a nice thing to do, and I always urge people to do it if they can, but don't give them your contact info because depending on your blood type they can be real vampires. Source I have O- blood and was contacted daily to donate blood for over a year, even when ineligible to donate blood (because I donated yesterday)

[–] Zagorath@aussie.zone 10 points 3 weeks ago (1 children)

I used to. "Why not?" would be the reason. I never felt anything at all afterwards. I would schedule my donations so I don't have any hard exercise later the same day, but otherwise it wouldn't impact my life at all.

I stopped after going to my GP for an entirely unrelated reason and being told that I had severely low iron levels. I don't believe it was related to donating, but it does mean they couldn't use my blood.

[–] jimi_henrik@lemmy.world 4 points 3 weeks ago (1 children)

You lose quite a lot of iron when donating blood:

Each time you donate blood, you lose between 220-250 mg of iron. It may take up to 24-30 weeks for your body to replace the iron lost through a blood donation. That time may vary, depending on what your iron level was before donating and if you take iron supplements or multivitamins with iron.

AFAIK many people are fine (no symptoms) with having low iron levels.

[–] ALiteralCabbage@feddit.uk 3 points 3 weeks ago

I'm one of these people! The only downside I've ever noticed to being somewhat anemic is that I can't always donate blood which irks me a little bit I guess it makes sense!

In the UK they're unbelievably serious about it. If your iron levels are a fraction below their threshold you're out and barred for 12 months (unless you get a blood test by your GP).

[–] Bahnd@lemmy.world 9 points 3 weeks ago (1 children)

Ive donated about a dozen times, mostly when its convienent like when they call our local donation bus out to where ever im working.

For the feeling, almost no effect. I mostly spend my time there cracking jokes about how this is a good way to lose weight, or how im only really there because I want a juice box and a cookie. Its more of an excuse to not have to be 100% mentally there for the rest of the work day.

As for the why, Ill sign up and donate when I can, but I dont seek it out. I know its important, but it is a donation, which because of the US insurance and medical industries will be sold to the person who needs it most. (Someone who knows more about this please correct me on it if that assumption is wrong).

[–] subtext@lemmy.world 5 points 3 weeks ago

Yeah same here, just whenever work brings a bus out. I feel a little icky that they’re just gonna turn around and sell it into the system at exorbitant prices, but I at least feel better that someone who needs it will get it.

I’ve never experienced any side effects either, other than just taking the bandage off too soon and having a leaky arm.

[–] rabber@lemmy.ca 8 points 3 weeks ago (2 children)

In college we would donate then go get drunk off one beer at the campus pub then go to class

O+ over here so I know I am able to help a lot of people. When I donate, I do a "power red" which gives more than a standard pull. Using the American red cross app makes it a bit more fun since I collect badges and can track all my visits. Also, since I read it can reduce plastic in your system, I see that as a double win.

[–] tgm@lemmy.world 7 points 3 weeks ago (4 children)

I would, but I can't. I am medicated for my ADHD and depression. Both disqualify me in that regard

[–] liran@lemmy.world 3 points 3 weeks ago (1 children)

Huh, in the US, they allow donors with antidepressants and ADHD meds. Source, im a regular donor who has been on both.

As someone who has received a blood transfusion, thank you random stranger whose blood is now inside me!

I want to "give back" somehow, but I obviously can't donate blood (yet?).

[–] Aganim@lemmy.world 6 points 3 weeks ago* (last edited 3 weeks ago)

Unfortunately I was rejected as a donor, the nurse had too much trouble hitting a vein (mine are difficult to spot and tend to roll when sticking a needle in them) for drawing blood for the pre-donation bloodwork. So that meant an automatic rejection as they prefer not turning the donors into living pincushions. ☹️

[–] liran@lemmy.world 5 points 3 weeks ago

I donate 2-3 times a year. I take a break every few years, things like tattoos and such. I’m O- and they don’t let me forget to donate for too long.

My dad was shot in high school (hunting incident) and received donations. He became a regular donor after, and i guess just set a good example of donating for us to see as kids.

[–] argh_another_username@lemmy.ca 5 points 3 weeks ago

I donated three times. The first was through a campaign at my workplace. Absolutely nothing worth noting happened. The second was through a campaign at my university. I fainted and my blood pressure went way down. The third time, a friend needed transfusion, so, the hospital asks for friends and family to replenish it. Since I fainted the second time, they took less blood. I was still a little dizzy but ok.

[–] fouloleron@lemmy.world 5 points 3 weeks ago (2 children)

Fun fact. People from the UK who lived there while BSE was a thing cannot donate blood in the US, pretty much ever.

[–] Aganim@lemmy.world 4 points 3 weeks ago

Ah yes, that's also a thing here in the Netherlands. If you've lived in the UK for 6 months or longer between Jan 1980 and Dec 1996 you cannot donate.

[–] v4ld1z@lemmy.zip 3 points 3 weeks ago

It's a question that comes up in the pre-donation examination at my facility too. Germany here

[–] hedge_lord@lemmy.world 5 points 3 weeks ago

I tried and found a cheat code! It turns out that if you pass out during the draw and then pass out again while recovering they'll call and pay for a cab to take you home! They did imply that I shouldn't come back for a while though...

On a more serious note I had donated blood twice before that with less dramatic results. I like helping people and they give me free snacks afterward. I'd been going every three months because I was in university and had a lot of time for such things. I seem to feel quite tired for the rest of the day following a donation, which I found nice and relaxing. Needle anxiety (and my weak-ass hemoglobin level) aside, it was a positive experience and I'd recommend it!

[–] Kyle_The_G@lemmy.world 5 points 3 weeks ago (1 children)

Just to add to the conversation I'm in school to be a med tech and transfusion is one of the proficiencies! Its pretty cool how it works, basically after the donation we spin it down into packed red cells and plasma. Plasma gets pooled and treated and can be fractionated out into specific coagulation products or used as a suspension for platelets. Packed red cells are filtered (leukocyte reduced), sometimes treated or irradiated and have SAGM added (saline, adenine, glucose, mannitol) to stabilize the cells for storage.

In the lab we test and crossmatch to make sure everything is compatible before giving the ok! Sometimes it is just ABO and Rh grouping but there are a bunch of other antigens on red cells that recipients can develop antibodies to with repeat transfusion so sometimes we need to identify if that antibody is present and match with units that don't have it so it won't react.

There are also a bunch of complications with testing like nonspecific antibodies, cold reacting antibodies, subgroups of antigens, Its really interesting!

[–] Aviandelight@mander.xyz 5 points 3 weeks ago (1 children)

Hello fellow med tech. The science is the best part of the job. Just wanted to pop in and wish you good luck with school.

[–] Kyle_The_G@lemmy.world 5 points 3 weeks ago

Thanks! I graduate next year, hoping to land a job in a path core. Can't wait to get working!

[–] HubertManne@moist.catsweat.com 5 points 3 weeks ago

no. im a needlephobe.

[–] HipsterTenZero@dormi.zone 4 points 3 weeks ago

I haven't yet, but plan to starting next month. I high key just want a little bit of extra change for my hobbies, hehe. If I could just grow plants with my blood, Little Shop of Horrors style, I would. Running it through a middleman is the next best thing.

[–] dicksteele@lemm.ee 4 points 3 weeks ago* (last edited 3 weeks ago)

I do. As often as I can. But sometimes the demand is so high for blood type that they call me up and email me even though I do donate regularly. My grandfather was a lifelong donor also.

I feel fine, the only discomfort is when the needle goes in but it’s fine once it’s done.

[–] GissaMittJobb@lemmy.ml 4 points 3 weeks ago

Yes. I used to donate the maximum amount of 4 times a year, but due to my inability to reasonably eat the required iron supplements, I'm now only allowed to donate once a year.

I do it for a mix of reasons - it makes me feel good about myself, I get a gift and a little bit of food, and I've told myself that it's probably not a bad thing to do health-wise, although the last one is completely unfounded.

After having donated, I feel noticeably weaker when trying to do things like bike or walk fast. Usually nothing major, though.

[–] MedicPigBabySaver@lemmy.world 4 points 3 weeks ago

Yes. I try to catch the blood mobile when it comes to town.

I think it's helpful to someone and I like to think of it as an "oil change" for myself. Generating a fresh pint.

[–] RebekahWSD@lemmy.world 3 points 3 weeks ago

Can't, iron levels are always too low because I have to get blood drawn for medicine every 3 months

[–] Kelp@lemmy.world 3 points 3 weeks ago

I actually donate a lot, bout every two months for whole blood. I do it all the time so afterwards I feel no difference, maybe a sore arm if the phlebotomist wasn’t the best. If you go in with an empty stomach you might feel crappy and if you go in dehydrated they’ll struggle getting the blood… and you’ll feel pretty crappy.

I do it mostly for the civic duty of it all. Better to help when you can imo. Also there is a ton of data about donating blood being good for you. I’ve seen articles on it helping remove micro plastics and PFAS chemicals from the body. So hey, might as well

[–] i_ben_fine@lemmy.one 3 points 3 weeks ago

I've tried three times and passed out twice. I pass out with simple blood draws, so they don't like me at the Red Cross.

[–] ambitious_bones@lemmy.world 3 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

I donate plasma once a week but right now have to take a break for a bit cause I got a tattoo. Only real Side effect is a craving for snacks and some additional cash in my wallet.

No, I fell out of the habit when I started having lots of casual sex and I have reynauds disease making it a long and uncomfortable process. Also I have a scar on my vein from selling plasma

[–] Opinionhaver@feddit.uk 3 points 3 weeks ago

I would but they don't want it.

[–] madjo@feddit.nl 3 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

I used to, but since I have contracted Long Covid, I've stopped, as both would sap my energy too much.

But in the past I have donated about 20-25 times. (once every 3-4 or so months)

How I felt afterwards depended a little bit on the nurse administering the needle, some are really careful and it's a painfree experience, others are a little less careful and then it can hurt like a motherfucker. (but for first timers they're always extra careful is my experience)
And for me, I just get a bit tired afterwards. Never really gotten woozy, but do take your time to recover in the waiting area after donating, and ask for something to drink (I recommend tea or fruit juice)

But it's also very important to drink and eat enough during the day before donating.

And the meme in The Netherlands is that you do it for the "pink cookie", which is a small cake-like cookie with pink icing on top. We don't get any financial benefits (other than reimbursement for any parking costs at the hospital)

[–] Aganim@lemmy.world 3 points 3 weeks ago

Ah yes, the infamous and delicious 'roze koek'. 😄

To put the latter part a bit more strongly: it is legally not allowed to pay for blood donations in the Netherlands.

[–] makingrain@lemm.ee 3 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

Yes, every 12 weeks, which is the minimum gap between donating in the UK. I always feel fine, usually I sleep for a longer period so I plan accordling and hace a restful day.

It's the least I can do.

[–] dumblederp@aussie.zone 4 points 3 weeks ago* (last edited 3 weeks ago)

Yeah same in Australia for me. Fwiw it's also a way to rid yourself of some of the forever chemicals lurking in your body, eg pfas. They worked it out testing firefighters* blood and the regular blood donors had less of the chemicals in their system.

*firefighters get excess exposure to the chemicals as they're common in firefighting foam.

[–] Vanth@reddthat.com 3 points 3 weeks ago

I haven't been able to for the last few years due to low blood pressure. So when they do blood drives at work or in my local community, I look for chances to volunteer in lieu of donating myself.
