Blood donation?

22 posts in this topic

Hi everybody

 

I just want to know that if blood donation helps me to maintain my BG and A1C?

I think when you donate blood A1c will defiantly reduce. but is it good for health too?

Or it is just a kind of cheating?!

 

any ideas?

is there any limitations?

or they are just fine like any other normal people?

There can be a temporary lowering of a1c, but I have never seen much. It certainly is not a strategy for control.

 

As far as limitations, the only ones I know of are if you are using (or have used) bovine insulin, you can't donate. Other than that, if you are well control, there are none. I have heard that donating blood is indeed good for you, but I could not list anything in particular that it has done for me (other than feeling good about doing something that helps).

 

Some people will see an increase in blood sugar after donation due to the stress on their bodies. I have not noticed that myself, but it is something to keep in mind.

This site says that people with well-controlled diabetes can donate blood:

Whether this does any good for your A1c is another question. My feeling is that it would be "cheating" in terms of the value of the A1c to tell you how your control has been over the past 3 months or so. I don't know if it has any health advantages, though.

I read once ( don;t know where) that blood donations are good for the heart, something about getting rid of iron. If you can donate, go for it, it can help save a life.

The idea behind this lies primarily with men or women post-menopausal. You accumulate iron in your body, you don't have a way to break it down. You can actually accumulate too much so donating blood periodically (I believe the current rule of thumb is once every 3 months) allows excess iron to be removed (not by itself per se, just a gradual reduction or you prevent the accumulation from happening). Women peri-menopausal or those who still regularly menstruate rarely experience this problem because of monthly menses. Hope this clears up the confusion on how it benefits help:) Another issue with donating: you will be turned away if: 1. blood pressure is too high and 2. if you're anemic.

 

Fawn

Donating blood is fine for diabetics, as long as they don't have any kidney disease as this puts more of a strain on them. Of course, there are other medical restrictions for donors, but just being diabetic isn't one of them.

The HbA1c test is a means of measuring the average levels of glucose in the bloodstream over time. Glucose gets stuck to hemoglobin - cells which typically live for 120 days. Removing the evidence of excess glucose by swapping older sugar coated blood cells for newer freshly minted blood cells (which the body creates to replace the lost cells) does not change history - just the perception or measurement of it. The question is: Is it the glucose stuck to blood cells that causes damage, or is this just a handy way to measure it? I think it's the actual glucose levels that matter and the sticking to blood cells is just a way to measure it over time.

 

Unless I'm wrong, in which case... never mind.

I think some people misunderstood me here.

Look , I wanna donate blood , I'd love to and I have done it a couple of time before I diagnosed with diabetes.

Now, my problem is that I'm afraid that blood donation changes the real Value of A1C test ( which I'm going to do it in the lab next month). I'm afraid that blood donation cause A1C to drop not because of the good diabetes control but because I some how eliminate the history of it.

And I do too. toby. However, no blood bank will take my blood because of another condition, but I have to have a phlebotomy monthly for it and wonder how much, if any, that distorts my A1C?

You could wait until just after your a1c and then donate...

 

Dang, there I go, being all logical again. ;)

I am also having monthly phlebs, & I am woring in case it distorts my A1c, did you ever find out any more, pat?

Too much iron in the blood can lead to hemochromatosis - it can cause organ damage over time... usually hits the liver first and it's a pretty common condition.

 

Moonpie/Pat - I'm assuming that you either have PV or hemochromatosis if you are getting monthly therapeutic phlebotomies. I doubt therapeutic phlebotomy or even donation decreases an A1c. But I think getting a transfusion would decrease the A1c a bit.

Q;What's wrong with too much iron in the blood?

 

dinycat

 

 

A:well, some folk ( like me) cannot get rid of excess iron. Most people just get rid of it as waste, but if you cannot do that, it is a toxin to the body & left untreated, would be fatal. There may be other reasons too, but I do not know them.

In Ireland people with diabetes are not permitted to donate blood, not because of sugar levels in the blood per se, as even well controlled diabetics are not allowed donate. The main reason is that there could be a risk of the donor going hypo after the donation.

 

What's wrong with too much iron in the blood?

As mentioned there is a condition called hemochromatosis, I believe there are two main types genetic and acquired. People with hemochromatosis have high levels of iron in their blood, which if left untreated can lead to:

 

* arthritis

* liver disease, including an enlarged liver, cirrhosis, cancer, and liver failure

* damage to the pancreas, possibly causing diabetes

* heart abnormalities, such as irregular heart rhythms or congestive heart failure

* impotence

* early menopause

* abnormal pigmentation of the skin, making it look gray or bronze

* thyroid deficiency

* damage to the adrenal glands

 

I understand that the common treatment for hemochromatosis is removal of blood phlebotomy, in the same was as you donate blood. The aim is to reduce the blood ferritin levels to within a normal/acceptable range, when that happens the patient then enters a maintenance regime, where a pint blood is removed every few months (I believe for life).

Schedule your a1c test, then donate blood right after so the test so that will have the least effect on your A1c.

I guess I just never thought about anyone having too much iron in his blood. I grew up always hearing about "iron poor blood", and Geritol. Remember?

 

But, of course it makes sense that too much of it would be bad.

 

Is this a regular check when our bloodwork is done? I mean, in the CBC?

Not sure about in the USA, but in Ireland a CBC (Complete Blood Count) blood test doesn't cover iron levels, in fact a CBC is not what I would normally have, it would be closer to a Chem Blood Test and my Doctor indicates what he wants checked (HbA1c, Glucose, etc). Next time you are having blood tests, just ask your Doctor if iron levels are checked.

A routine CBC can alert you to this potential problem by having a high Hemoglobin value (12 g/dL to 16 g/dL for adult females, 14 g/dL to 18 g/dL for adult males, typically). But a high HGB is not always because of high iron blood. Heavy smokers will have a higher HGB because their hemoglobin isn't as effective as a non-smokers; carbon monoxide has a very high affinity for the sites on hemoglobin that carry oxygen, so a heavy smoker needs to produce more hemoglobin to increase the number of sites available for oxygen. One of the diseases in which routine phlebotomy is used as treatment, Polycythemia Vera, is easy to detect on a routine CBC. "Normal" people produce about 4 million to 6 million RBC's per microliter of blood. This is displayed in the CBC as RBC. People with PV typically have an RBC Count of approximately 10 million. Their hematocrit and HBG concentration increase proportionally too.

 

I believe a routine Iron/TIBC (or just Iron Panel/Iron Studies) will reveal whether there truly is too much iron. It's a common test/panel, even most small labs have it available on their test menu. If you are concerned, perhaps your physician will order it for you.
