If you have been diagnosed with HYPOTHYROIDISM,... - Thyroid UK
If you have been diagnosed with HYPOTHYROIDISM, what is your blood type?
It would be interesting to compare this graph with the percentages of the population having each blood type.
Here's a link. Scroll down to see the chart 
quite interesting its a high percentage of us B+ compared to the population! Unless we are just eager beavers on polls
Often wondered about THAT.!
Wow. I see my blood type is very related to hypothyroidism, 0+
first thing i thought of too.
I imagine this chart will continue to change quite dramatically until a lot more people have voted. It is very intriguing though. I can't wait to see if there is a correlation between blood group and hypothyroidism that differs significantly from the blood-group distribution of the UK population.
You are right CarolynB, lets wait and see final results. It changes so quickly.
I would imagine the large proportion of O positive is due to it being the most common blood type.
Wiki has the same figures as the Blood link CarolynB posted above.
United Kingdom
Population - 63,047,162
O+ 37%
A+ 35%
B+ 8%
AB+ 3%
O- 7%
A- 7%
B- 2%
AB- 1%

In order to make any sense of the poll percentages we are seeing, you need to think of them together with the proportion of the population with each blood group. At this moment O+ is showing 32% in the poll - but 37% of the population have O+. So it is slightly lower than would be expected - but probably completely insignificant with the small numbers who have "voted" so far. Until many more have recorded their blood groups, we cannot hope to make anything of the results.
Even if there does appear to be some correlation with blood group, it does not show a causal relationship. For example, maybe people with blood group XYZ+ are much more likely to have computers and take part in on-line polls?
This echoes what has been said by others.
Can we have an answer of "Don't know" ? I have no record of my bloodtype, so no idea.
Both Blood Groups AB (+ and -) and the negative (all types) seem to be a little more common at the moment.
I am a Rhesus AD Negative which I don't see on the poll . Thyroid problems are inherited so not sure it has much to do with blood type !
I'm a little confused. There is AB negative or do you mean that you are A but negative for the D rhesus factor? There are both options.
It's not always inherited. My doctor has asked me multiple times if anyone in my family has thyroid problems, but there is no one!
Hi Susie -not all thyroid problems are inheriterited -there is'y anyone else in my family with hypothyroidism -just little old me! e.g you can develop thyroid problems due to flouride etc...
my youngest daughter was found hypo 12 years ago at the age of 29 her doctor told her someone else iin the family will also have it so my oldest daughter got tested weeks later and yes she was hypo at age 35 so myself and sister went to docs and sure enought we both were hypo too at age 54 and52 . that was all the space of 12 weeks. we are all on different levels of medication but all feel quite ill most of the time , so in our case yes it did run in the family although we cannot find anyone before us who had it unless they were not diagnosed .
Hi I was diagnosed in S Africa in 1978 at the age of 30 after suffering with a thyroid condition from about the age of 12 ( could be earlier but I only noticed the size of my neck then ) my gynocologist at that time made enquiries about the area in Uk I was born and grew up in .. the info available back then ( via a phone call from Boots ) there was a larger incidence of thyroid problems in Yorkshire at that time as it was found their investigations showed no '' iodine '' in the soil .. but there must be other areas showed up since then where there is no iodine in the soil.
As to being inherited I wouldnt know but my mom had a moon face/neck, was never really well and passed away when she was 52 and she was born and raised in Swansea ? its a mystery
That's interesting to see how many of us have B+ on this and have hypothyroid problems. I wonder how many of those B+ people are also celiac in some form.
It would also be interesting to see how those WITHOUT an "official" NHS designation of hypothyroidism, but have managed to get a diagnosis privately, compare with those on this poll.
I haven't voted as not told I'm 'diagnosed' just borderline (apart from missing half a thyroid and hypo symptoms!) anyway O+ - so one of the most common 37% Jx
Nothing to note really as this would also be a reflection of the blood type analysis of the world, with or without hypothyroidism.

Maybe do a poll to see how many women went under active after receiving a Rh D immunoglobulin injection. I went under active after 3 months of having it ?
I believe that blood groups A & O are the most common blood groups. So it would make sense that thyroid sufferers would probably fall into theses two groups. .No doubt someone will come along & prove me wrong - got no worries with that
ps I mean more would fall into these two main groups.
Have there been any theories that hypothyroidism and blood group are linked?
Someone suggested the idea for the poll to test that theory. xx
At the moment it looks as though blood type doesn't really matter, when you list them side by side only O- and B+ change places with a 1% difference.But I expect with a few more people taking part it might start to show something?
Mind you that's only my working out...
Hi to the others in my select little group of AB + blood
LOL

Greetings AB+ ! Such a shame our blood group isn't more appreciated. I'm hoping to be able to donate blood this year so I can find out if there is anything useful in it 
Hi fellow AB+ person!
They refused when I offered to donate blood... just because I take asthma meds ( spray). I found that rather OTT really.
Apparently we can accept everyone's blood but only our own group's plasma. So let's hope there are enough of us AB ers around donating or we wouldn't get plasma if we ever need it.

I notice that O- is 15% in the chart but only 7% in the population. A- is 11% in chart and again 7% in the population.
Im a rhesus neg AB with underatctive thyroid. It runs in family my daughter has it and my dad has over active thyroid.
Is this only for hypo? I have graves
Joined today as wanted to find out if there was a correlation between blood group and hypo I'm 0 neg.
I've been feeling really tired recently - will be seeing GP next fortnight - I would be interested to find out more when people take their medication. Have read that a small study was done and showed that it's better to take med at night - any comments from anyone out there?? thanks
Hi and welcome. With respect to taking thyroid medication at night, this is a very individual thing. For some, changing from morning to night has made a very positive difference. For others, nothing much changed, and for others, it had a negative effect.
If you haven't already done so, read through the comments on the poll we have done on this very subject. It's here
Can I just ask -is this poll just for the UK? if not it will be hard to evaluate the percentage of different blood groups to the norm as it varies from country to country. E.g According to Wikki in the UK 7% of the population are O Rheusus Negative in India it is 2% and in Spain 9% -poll is displaying 15% at present....which would seem to idicate a higher incident rate...assuming that other factors are taken into consideration.
Seems like a valid enough question Wavylines. Whilst we certainly do have some non-UK members, I'd guess that the vast majority of poll responders are at least in the UK. But whether or not they were all born in the UK is another matter of course.
I'm B+ This poll shows that 8 per cent of people diagnosed are B+ which is in line with the percentage of the population who are B+.
A+
I am B+ and have autoimmune thyroiditis, thyroid problems run on both sides of my family I have recently found out, my dad was diagnosed hypo last week his sister had Graves and is now hypo, my mums sister has autoimmune thyroiditis, have various cousins with various thyroid problems and my 17 year old daughter was diagnosed hypo aged 10.....don't know any of their blood groups though!
I am O NEG my parents were both NEG neither of them had hypothyroidism. However my two step sister have it.
I have been following blog for some time for people with RH- blood groups .
There is a surprising amount of auto-immune and thyroid problems considering the percentage overall of RH- types
Here is a link if you are interested
How many would have to participate for this to be statistically viable? Interesting results so far (I'm O-)
RH Neg anti D I think not on there or maybe I have got it wrong
