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

  • Published: 10 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.

                          It wouldn't surprise me if, after having his first vodka, he had to be hospitalized, and that's where his B12 deficiency was first documented.

Even without any particular disease evident, it's not exactly rocket science to decide that a diet consisting solely of potatoes, salt and vegetable oil is super bad for you, and that you should fix this before something in the patient breaks.
