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

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.

These cases are patients who I, or my colleagues have seen. They are de-identified and many instances have been presented in more depth in an academic setting. These videos are not individual medical advice and are for general educational purposes only. I do not give medical advice over the internet, see your own physician in person for that.
