It’s rare for me to even get a stomach bug. My daughter and son are also AB, and all of this applies to them too.

We may just be the lucky underdogs. 😂 (This is meant to be very tongue-in-cheek, so don’t come at me.)

A- here, and I want to come at you. But I don’t have the energy.

Type AB is just a combination of type A and type B (hence the name). It’s the most recent blood group (of the 4) to emerge. It first came into existence when a person with type A blood and a person with type B blood had a child together. Anyone with type AB has both the A and B antigens on their red blood cells. Technically, you’re simultaneously team A and team B.

We get a lot of people who think they’re B (+ or -) when they’re actually O (+ or -) or A (+ or -). We also get a lot who think they’re the universal donor (O-) when they’re actually O+ (the most common blood type). Many can also not accurately remember whether they are + or - even if they know their correct ABO group. These are the most frequent mix-ups for some reason.

I’ve noticed this too. I think it’s just human nature to want to feel special or unique, even when it comes to something like blood type. The amount of people that I’ve seen claiming to be the universal donor is very disproportionate to the percentage of the US population that genuinely is O- (between 7 and 9 percent).

Maybe I’m selfish, but I’d rather be AB+ than O-. It’s more beneficial to the individual. O- can donate blood to anyone with any blood type, but AB+ can receive blood from anyone with any blood type. Those who are O- can only receive O- blood.

Anyone who is O- and needs a blood transfusion will be straight out of luck if they ever have a severe shortage of O-.

I’d rather be type A than be either of those. I believe studies have come out that identify type A as the blood type with the lowest risk for the majority of illnesses and as the most protective against viruses and infections. This was an area of interest and research during the COVID pandemic. I remember people talking about it. Unfortunately, I’m (along with my DH and kids) stuck with O. That genetic lottery business is brutal.

Wrong, unfortunately! Blood type A is hands down associated with the most health issues- increased risk of many cancers, heart disease, and severe Covid too.

I’m blood type A (Rh positive) and in extremely good health compared to the other people that I know who are around my age and even those decades younger than me. I may be a statistical outlier, or it may be in part thanks to environmental factors (not sure), but I feel pretty content and grateful. In my case, I don’t feel that my blood type has elevated my risk or been a hindrance to my health.

It might be a coincidence, but every single person that I know of who is type O has some sort of problem with some part of their digestive system/GI tract and experiences digestive symptoms. They usually struggle with spicy or acidic foods and dairy products. It doesn't matter how healthy they otherwise are. This is a common theme.

What data do you have to show this is a "common theme"? I have O type blood, and no GI issues whatsoever, similar to my family members who are also type O. You may need to take a basic statistics and a basic biology class before spreading weird anecdotes.

Did you bother to read the articles you posted? More severe incidence of cholera in people with type O blood is not the same as saying that all people with type O blood suffer from gastrointestinal issues and can’t eat spicy food.

Did you bother to read the rest of the links (particularly the 3rd one)? https://link.springer.com/article/10.1007/BF02239355

There is NEVER going to be a study that establishes that ALL people with type O blood suffer from gastrointestinal issues, as researchers do not deal in absolutes. I have simply provided evidence that there is a demonstrable link/correlation and potential causation (gastric hyperacidity associated with type O blood).

Additionally, there is a reason that 1st link regarding cholera and a few of the other links were included. I needed to show that a link between blood types and disease/illness susceptibility and severity risk has been established, as the poster that I responded to was trying to discredit that premise entirely. Funnily enough, there are other posters on this thread establishing a link between type A blood and medical conditions, and that poster has not attempted to disprove them.

It’s because she’s type O herself and got all offended by what was said like it was a personal attack on her or something. She’s fine with type A being labeled as unhealthy because she’s not type A.

To OP, I once switched OBs mid pregnancy due to an insurance change and the second one had my blood type listed as A+. I had always been told my blood type was B- (easy to remember because I joke I can't stop being a pessimist because it's in my blood 😂) so I asked her. She went through all my transferred files and couldn't find my blood type written anywhere so she redrew it. It turns out that I am B- and what had happened is that my first OB hadn't included my blood type anywhere and the EHR had auto populated that field. 😳 So yes definitely double check. Medical documentation errors do happen even with good doctors and they can be dangerous (for example if I hadn't caught that, she wouldn't have known to offer me rhogam).

I would trust your blood donation center and their testing lab more than your doctor’s office. They’re required to get your blood type right and be meticulous in doing so because they’re responsible for sending out blood bags to be transfused to people in need. If they label a bag of blood incorrectly, a recipient could die or be seriously injured.

They were waiting on my daughter’s blood results when she was in the emergency room of our local hospital before they transferred her to another hospital, and I heard the legitimate doctor say to someone else, “Yeah, the RH type is still pending. You can honestly just assume she’s going to be positive because most Hispanics are.” This was in our small town in New Mexico.

Let’s just say that I don’t have high hopes for all doctors. They’re a mixed bag (like every profession). When it comes to your health, never take anything at face value. Always verify.

The hospital checks too gor this reason

Unless I somehow didn’t see it you missed mentioning the fact that blood group O is the most susceptible to norovirus (stomach flu), which obviously has an impact on the digestive system. It causes inflammation of the stomach and intestines. (If you have ever had it then you know it’s brutal!!) You’re right that we’re (group O peeps) more prone to digestive problems overall. The other blood groups are more prone to other problems. The evidence is out there. We can’t change our blood group, but we can remain aware.

When I was pregnant, they told me that I was A- and needed RhoGAM when my blood type has always been A+. I ended up finding out that I have the weak D variant (which means that I’m genetically Rh positive but my blood can sometimes appear as Rh negative because I have a reduced amount of the D antigen).

I refused RhoGAM before and after birth because it’s completely unnecessary. I’m scientifically Rh positive.

You need to speak with a hematologist. They specialize in all things blood related.

Your blood type doesn’t randomly change. It is genetic. It stays the same throughout your life like your eye color.

Well your eye color definitely changes throughout life and not just from cataracts. Babies often have blueish or violet eye colors that turn hazel. And hazel eyed people’s eye colors change with their mood - if normally brownish they turn amber or green when they get mad or if normally green they turn blue when they get upset.

They can change from a lighter color to a darker color in infants and toddlers because babies do not produce much melanin when they’re first born. That’s why a lot of babies are born with blue eyes that later turn brown (for example). In those babies, it’s not really changing though because their eyes were always going to be brown based on their genetics. Brown is always their actual eye color that their genetics coded for. Once you have your final eye color, it does not truly change (unless you have some sort of medical condition). It’s simply an optical illusion.

That’s why I’ve always thought mothers were weird for asking how they can prevent their baby’s eyes from becoming darker (which I see often on mom forums). If their genes/alleles determine their eyes are going to be brown, then they’re going to be brown. You can’t stop it. The same applies to skin color and hair color.

I’ll never understand the societal obsession with non-brown eyes. I have always loved medium to dark brown eyes (the type that are pure brown with no yellow or green hue or any other color). The darker the brown, the better.

My eyes are hazel (a mix of light brown, green, and yellowish). I’ve never liked the color. I’m just grateful that my eyes function properly, though. The color of them is just a superficial thing.

It’s probably because brown is, by far, the most common eye color worldwide. If blue or green was the most common color, then everyone would obsess over brown eyes. People like what is uncommon. Also, humans in general tend to like and want what we don’t have.

Same here. I like eyes that are so dark brown you can barely see the pupil. 🤎👀
