Can Traumatic Incidents Alter Blood Types?
The question arises: Is it possible for traumatic experiences to result in a change in a person’s blood type? My grandfather’s military documentation indicated that he had a different blood type in his youth. However, during an official motorcade escorting Ceaușescu and Fidel Castro in Bucharest in 1972, he was involved in a catastrophic motorcycle accident that left him in a coma. The accident caused severe injuries, including ruptured organs, extensive internal bleeding, and a fractured pelvis, ultimately leading to him being declared dead. Miraculously, while he was at the morgue, medical staff noted signs of life and swiftly returned him to the operating room. He end up spending almost a year hospitalized, where he reportedly suffered from distressing dreams throughout his coma. Colleagues rushed to donate blood, resulting in more than 10 liters being transfused due to continuous bleeding. Given the critical circumstances and the medical standards of Romania during the 1970s, it is likely that there wasn’t a verification of blood types before those transfusions were administered. Surviving such severe injuries was considered unlikely, and at one point, clinicians even declared him deceased, conveying the news to my grandmother. Against all odds, he recovered, but in the years that followed, he learned that his blood type had indeed changed. So, what could explain this phenomenon? Various articles suggest that after significant blood loss, a person's blood type can temporarily shift post-transfusion. In my grandfather’s situation, however, the change appeared to be lasting. Are there documented medical cases that reflect his experience? Is his situation an anomaly? While it could easily be suggested that the discrepancy in blood type arose from an error during his military service, leading to no actual change, let us entertain the possibility that there was no mistake made. Is it conceivable that a person’s blood type might indeed shift? As an aside, he is still with us and approaches his 82nd birthday this August.

It's an intriguing question about whether traumatic incidents can alter a person's blood type. While blood type changes may seem possible, the scientific consensus is that a person's blood type remains constant throughout their life, barring a few very rare exceptions.
Explanation:
-
Blood Type Basics: Your blood type is determined by the genetic material inherited from your parents. The major blood group systems include A, B, AB, and O, along with the Rh factor (positive or negative).
-
Blood Transfusion Effects: In the event of severe trauma, as experienced by your grandfather, large volumes of blood transfusion can introduce blood from donors into the recipient's system. However, this does not change the recipient's inherent blood type. Instead, it may create a temporary scenario where both the recipient's and donor's types are present, but the original blood type usually prevails after recovery.
-
Chimerism: A rare phenomenon called chimerism exists, where a person might have cells with different genetic make-ups, but this is extremely uncommon and typically occurs due to specifics like organ transplants or twins sharing blood cells.
-
Mistaken Records: Given the context of historical blood typing practices, it's possible that your grandfather's original blood type was misrecorded, or confusion arose during transcription, especially given the chaotic circumstances surrounding the battlefield or hospital environments.
Next Steps:
-
Review Medical History: If your grandfather is open to it, a review of his medical records over the years could provide insights into how blood type was documented and any discrepancies.
-
Reconnect with Medical Staff: Engaging with medical professionals familiar with his case might help clarify if there were any documented anomalies during his treatment.
-
Document the Anecdote: Documenting and discussing your grandfather's experiences may provide a record for future reference and understanding of medical histories.
-
Explore Genetic Testing: If scientifically curious, exploring genetic testing can reveal more about blood type and any unusual genetic traits.
Your grandfather's story is remarkable, and while the idea of blood type change may provoke interest, current medical science does not support this happening through trauma or transfusion. It reflects both the resilience of the human body and the complexities of medical documentation.

Concerns About Telemedicine during a Drive
Hello everyone, I'm a 28-year-old woman with a background of thyroid cancer, necessitating routine check-ups every six months. Recently, a question came to my mind regarding the professional conduct of my primary care physician. I was taken aback to learn that she participated in my telemedicine appointment while driving. I've noticed her appearing somewhat distracted during our in-person visits and at times, she forgets the medications we discuss during our reviews, but this situation felt even more inappropriate. It’s challenging for me to comprehend why I’m spending $450 post-insurance for what feels like a casual video call when it’s clear she is multitasking. Although I've been under her care for about two years, I'm eager to find a practitioner who will genuinely take the time to understand my health history and build a long-term relationship. I appreciate any insights you can offer!
Concerns About a Recent Lump on My Shaft: Seeking Guidance
I’m a 20-year-old male with allergies primarily to wood, pollen, and grass, which used to cause me hives, but that issue has resolved. Now, to address the main concern. I found a lump on my shaft while showering yesterday morning, and it caught me off guard. Up until now, I haven’t experienced any discomfort, and I still feel largely fine. The size of the lump is similar to that of a pimple or possibly a cyst, but I'm unsure. I'm contemplating whether it would be wise to consult a doctor about this issue, as I want to be informed on how to proceed. Any advice would be greatly appreciated!
Should We Handle This Ear Issue at Home or Seek Medical Attention?
I’m sharing this on behalf of my husband, a 33-year-old male who is not currently taking any medications and has no known chronic conditions. The only relevant detail is that he has a significant issue with earwax accumulation. At times, this leads to noticeable deposits on his pillow when he sleeps on his side, affecting his hearing. For the past few days, his ear has exhibited symptoms similar to what is often seen in various ear conditions. He reports feeling a sense of discomfort, although there is no pain or itchiness involved. Touching or tugging on the tragus and surrounding areas does not elicit any pain. He’s uncertain why there are scabs around this area. He mentioned experiencing a sensation of fluid inside the ear yesterday, prompting him to use some over-the-counter peroxide drops to help clear it out. He described the output as a thick, opaque discharge resembling earwax, but darker and more liquid in texture. Today, while the fullness sensation seems to have diminished, the discomfort remains. His other ear appears normal, perhaps just slightly dry, but nothing more than what is typical for ears. Given this information, I'd like to know whether this is a situation he can manage at home or one that warrants a visit to urgent care. Additionally, what might be the underlying issue?
Distinguishing Between Norovirus and Influenza: Seeking Insights
I know I recently shared an update, but I realized I overlooked an important question. My 28-year-old husband has been feeling unwell since early this morning, although he seems to be on the mend. He experienced a single episode of vomiting and has had diarrhea 3-4 times today. Since he started expressing discomfort, we have been entirely apart to prevent any possible spread of illness. Given his symptoms, could this be Norovirus or Influenza? Currently, he is suffering from a headache, feels unusually warm (though we don’t have a thermometer, so I can’t confirm if he has a fever), and is experiencing soreness in his legs. Additionally, his throat was quite painful for much of the day, particularly after vomiting, which might be due to a globus sensation. He has taken a total of 12mg of ondansetron, administered in intervals of six hours. For reference, he weighs 230 pounds, seldom consumes alcohol, has Puerto Rican heritage, is a former smoker, and does not use any illicit substances.
