The IFvitamin B 12 complex can enter mucosal cells in the distal ileum by receptor mediated endocytosis
It is a peptide made up of three amino acids: Glutamic acid, Cysteine, and Glycine.
Vitamin B12 deficiency Having trouble absorbing vitamin B12 from food, lacking intrinsic factors (for example, as a result of pernicious anaemia), having gastrointestinal surgery, taking certain medications for an extended period of time (such as metformin or proton pump inhibitors), and nutritional deficiencies are all causes of vitamin B12 deficiency
Additionally, tapering NE before reducing the AVP infusion rate could potentially prevent rebound hypotension [21, 22], although this approach is not consistently implemented, and the influence of other factors that mitigate the risk of rebound hypotension during recovery remains unclear
