      Wondering just what your daughters issues are? I’m recently diagnosed and having digestive issues that let me to this video after months of research. Wondering if vitamin b is the issues, hcl, pepsin OR none of the above.

      Well, I, personally got my b12 results back (actually saw a hematologist to make sure I’m actually absorbing the b12 I’m taking) and my b12 is good so has to be something else. What are your daughters issues. I know she has ms but my symptoms appear to be TOTALLY unrelated. Docs response….well, you have ms. Still digging! Look @ Epstein Barr. That’s where I’m headed. Good luck to you. Your daughter is in my thoughts.

    Comment from a different video, copy-pasted:
    "I'd like to add something about the weird terminology here, just details but might help someone:
    1) haptocorrin = transcobalamin I (and I think formerly aka transcobalamin III) = cobalophilin = R-protein = R-factor = R-binder ("R" stands for "rapid electrophoretic mobility").
    2) The intrinsic factor receptor in the terminal ileum is also called "cubilin"; the receptor in the kidney that's responsible for the B12 reabs. is the same like the one in the terminal ileum (it is also cubilin!) with the small difference that megalin was added to this receptor (which means this receptor is more "elaborate" than the one in the terminal ileum). Also, in order for cubilin to work, you need a membrane protein that will make cubilin stay put (and will help in the endocytosis, once B12 bound), this protein being called "amnionless".
    3) A mutation in cubilin or amnionless (autosomal recessive) leads to the Imerslund-Gräsbeck syndrome (syn.: defect of enterocyte intrinsic factor receptor, enterocyte cobalamin malabsorption, megaloblastic anemia 1, juvenile pernicious anemia with proteinuria due to selective intestinal malabsorption of vitamin B12), 1:200k in Finland/ Norway --> patients will have problems with both, B12 abs. AND reabs (remember, cubilin/ amnionless is present in both organs).
    4) B12 bound to transcobalamin II (the transporter in the blood) is called "Holotranscobalamin" ("active B12").
    5) Haptocorrin is also produced in the stomach, not only by the salivary glands; and, as said in the vid, haptocorrin can bind 80% of the B12 in the blood making it unavailable for use."
    If you want to add/ correct something, feel free to do so

    Another great video. One major cause of B12 deficiency which I was surprised you didn't mention is alcoholism. I will assume this is due to alcohol damaging the illium and preventing adequate absorption. Additionally alcoholism generally goes hand in hand with poor diet/malnutrition which also accounts for the deficiency.

    • @garyjamesstanton414
      @garyjamesstanton414 2 роки тому

      @@lynserkawi4704 yes, it does indeed take years to deplete stores of b12. 10 years is more in the realm of a theoretical maximum depletion time, but in practice the depletion time is around 2-4 years. In a liver damaged by alcohol, it cannot store as much b12 as a healthy liver so this is a factor as well. Interestingly, serum b12 levels can appear normal in those with severe alcoholic liver disease as the b12 can be "leaked" by the damaged liver which masks the otherwise low serum b12.

    American Academy of Neurology:
    People with inflammatory bowel disease may also be at risk for
    developing nerve damage and other neurological problems, according to
    research that will be presented at the American Academy of Neurology’s
    59th Annual Meeting in Boston, April 28 - May 5, 2007.
    Inflammatory bowel disease includes digestive disorders such as
    ulcerative colitis and Crohn’s disease that cause swelling and/or
    bleeding in the intestines. For the study, researchers compared 103
    people with Crohn’s disease and ulcerative colitis to 51 people with
    other digestive disorders, such as irritable bowel syndrome, gastritis
    and chronic heartburn.
    The researchers found that those with inflammatory bowel disease were
    about four times more likely to develop neuromuscular conditions,
    including carpal tunnel syndrome and small fiber neuropathy, which
    causes pain and lack of feeling in the feet. Those with bowel disease
    were also more than six times more likely to also have a disorder called
    sensorimotor polyneuropathy, a nerve disease that can cause weakness,
    pain, and numbness. These diseases were more common in women with bowel
    disease than men.
    “Inflammatory bowel disease patients commonly suffer from several other
    medical conditions, like B12 deficiency and glucose intolerance. These
    nerve conditions we have reported are often not diagnosed by their
    primary care physicians,” said lead study author Francisco De Assis
    Gondim, MD, MSc, PhD, Professor of the Federal University of Ceará in
    Ceará, Brazil, and a member of the American Academy of Neurology.
    “People with inflammatory bowel disease who develop new symptoms, such
    as pain or numbness in the feet, should see a doctor.”

    Please somebody help me. I’ve just realized the reason I have b12 issues is stomach acid related but I also have extremely high cobalt which is toxic obviously because my body hasn’t been working the way it’s supposed to. How do I take b12 and absorb it without the extremely high cobalt happening?
