How does nitrous oxide interfere with B12?
Nitrous oxide interferes with vitamin B12 metabolism, by oxidizing the cobalt atom and irreversibly inactivating the enzyme methionine synthetase [6]. This impairs the production of methionine (from homocysteine), a substrate for tetrahydrofolate and thymidine during DNA synthesis.
Does B12 increase nitric oxide?
In conclusion, we suggest that nitric oxide is associated with the serum level of vitamin B12 in patients with megaloblastic anemia. The replacement of vitamin B12 in patients with megaloblastic anemia restored, at least in the early phase of treatment, the significant increase in the levels of nitric oxide.
Does B12 affect anesthesia?
Patients with vitamin B12 deficiency are exceedingly sensitive to neurologic deterioration following nitrous oxide anesthesia. If unrecognized, the neurologic deterioration becomes irreversible and may result in death.
Does nitrous oxide cause pernicious anemia?
Pernicious anemia is the most common cause of vitamin B12 deficiency, while nitrous oxide abuse is an emerging but rare culprit. There have been relatively few documented cases of combined recreational nitrous oxide and pernicious anemia–induced polyneuropathy.
Does nitrous deplete B12?
Neurologic symptoms associated with nitrous oxide use have been attributed to vitamin B12 deficiency. Through oxidation, nitrous oxide inactivates vitamin B12. In its inactive form, vitamin B12 is unable to function as a co-factor for methionine synthase and methylmalonyl coA mutase.
Can Vitamin B12 deficiency cause vitiligo?
Skin lesions associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. Cutaneous lesions that do not respond to conventional therapy can be an indication of vitamin B12 deficiency.
Is vitamin B12 good after surgery?
Commonly used to combat memory loss, Vitamin B12 also strengthens the immune system and bolsters energy levels. Some bariatric procedures make it more difficult for the stomach to properly release B12 during food digestion, so a B12 vitamin is recommended following surgery.
What does B12 do for skin?
B12 is necessary for the reproduction of cells throughout your body, including your skin cells. It is known to reduce skin cell inflammation and dryness, and B12 is found to be effective for treating and preventing skin conditions like acne, psoriasis and eczema.
