Blood Donation Questions

You can drive no problem.

I'm not sure about the rest but it's really not a big deal.

1. It's a couple of miles down the road. Will I have any issues driving myself there and back?

Shouldn't be a problem, they usually won't let you just jump up and take off encouraging you to hang around a bit to assess any effects (like being dizzy).

2. Other than the social utility, are there any benefits to donating blood from a health standpoint?

---

Donating can lower your hematocrit levels and that can be useful if they're too high. Hematocrit is essentially the viscosity or thickness of your blood, too much can be bad.

3. Are there any drawbacks or adverse health effects to donating blood?

On the other hand donating drops your iron levels and too frequently can drop them to the point of leaving you fatigued and other issues. I typically donate no more than once/qtr.

Some people get light headed but its usually for low blood sugar. They will have things to eat there in case this happens. Might have to chill for 10 mon after but will be fine to drive after that. I give often and don't get light headed at all. I have seen people puke though and even some pass out so it happens.

But don't let that persuade you as its rare and usually small females with those issues.

Benefits would be bringing your hematocrit levels down. Also most check for the covid antibodies along with checking for other disease like aids.

No real downsides for 95% of people.

Driving should be fine.

I used to donate as much as I could when I was growing up. Then I started having scary near-blackouts immediately after donating. Like, within a minute of the needle being removed. My ears would start to ring, I would feel cold, and then my vision would get dark.

I asked an old PCP about this and he recommended that if I'm passing out I shouldn't plan to donate blood while on my high blood pressure meds. Or considering not taking it the day before donating, which seemed questionable. I'm also very confident I suffer from Micturition syncope and I wonder if they are related at all.

Shouldn't be a problem. I've never felt immediate effects.

I did feel fatigued for a full week once, but that was after donating 5 times in a one-year period, so now I limit myself to 4 times a year.
