A Student Ate Only Chips And French Fries For 10 Years. This Is What Happened To His Eyes.

  • Published on: 09 September 2019
  • This case is based on publication in literature by Harrison R, Warburton V, Lux A, Atan D. Ann Intern Med. 2019 Sep 3. Link below. Non-clinical elements (e.g. initials, story details, etc) are adapted. Peer Review: Dr. Nikhil Parelkar.

    I originally had another case for video of a vitamin b12 deficiency I saw as a student about a girl on an overly strict diet. I didn't release it because the details were more difficult than I would like for a video. The clinical principles and science of that case and this one are the same.

    I wish all doctors were this educated in b12 deficiency. I was diagnosed in 2015/2016 and because of lack of proper treatment, and being deficient for so long (I nearly ended up in a wheelchair) I was left with nerve damage. My doctor has since cut me off injections leaving me to fend for myself and self treat 😔 I eat a full range of foods, have never been a drinker and have never been vegan/vegetarian. No one will test intrinsic factor. Focus is on "level" of b12 rather then whether or not it is actively being used.

    I'm pretty picky too...the only foods i really eat are pizza, anything chicken, and fries. I stopped eating fish after seeing that one episode. With the worm. Ummm. I technically love eggs and bacon but I'd be lieing if I said I ate a balanced breakfast every day. Steak is ok. I hate salads. Hell I hate anything green. like no joke vegetables are a no go. I don't eat any type of vegetables. Thats probably bad for me. I also drink exclusively DR pepper my mom keeps telling me I'm going to have a kidney stone. This video was a real eye opener. I think I'm gonna try to eat new foods

    I bet this kid had asperger's disorder or autism spectrum disorder. They often have food jags like this where they'll only eat one or two foods.

    I'm going to subscribe because I like the methodical way you go through symptomology, diagnosis and treatment including including lab values and reference ranges along with radiological findings in a comprehensive manner. But please don't ever get too smart. Self assured brilliance kills many patients. Physician Ego has been the final nail in many of coffins. The most brilliant specialist I have ever known maintain the clinical skills that you display with humbleness and prowess. I would like to ask you to do a case study on acquired hemophilia with factor 8 inhibition triggered by tylenol. It is very rare. But not as uncommon as you might think. Mainly because it is never recognized and by default not documented by most clinicians. If you encounter it and properly diagnose it soon enough a patient can be saved. But its initial manifestation is confusing to say the least. The only way to stop it is by administering copious amount of factor 8. It's like treating a patient in a constant overdose of heparin with an INR that just keeps skyrocketing. Vitamin K will have little to no affect. Acetaminophen is the trigger particularly in elderly patients postoperative and administered tylenol. I think you could portray a case study with the same intrigue and fascination as the other videos you have done so brilliantly. Thanks for the videos.

    I take Vitamin B12 for my depression. There’s a lot of medical and scientific research that suggests Vitamin B12 can help people who struggle to absorb seratonin in the brain. Not many people understand that depression can lead to anemia and neglected eating habits which is what happened to me. I also take iron and vitamin D because my mental illness puts me at risk of having low or unbalanced nutrition.

    Before I actually watch this, we had a teenage male on the west coast of NZ that went blind from malnutrition ( from a restricted diet like this).

    When I was a student, I ate a lot of carbs, mostly pasta. It was the only time in my life I needed glasses, and I also had ringing in my ears.Jesus christ Paleo really did save my life (mostly because it got rid of the inflammation I had all over my digestive system)
