Guest guest Posted December 27, 2004 Report Share Posted December 27, 2004 Hello, Anyone have experience with vitamin A deficiency? The patient was taking routine chewable vitamins---her surgeon now has her using spray vitamins (8 sprays per day) which is very difficult to continue. She did receive 2 doses of Viatmin A injections after the diagnosis. Any thoughts? Gerri French, MS, RD, CDE Quote Link to comment Share on other sites More sharing options...
Guest guest Posted November 28, 2006 Report Share Posted November 28, 2006 Aquasol A or other dry tablet would probably be absorbed better than an oil based capsule. I'm not sure of actual doses available in the various forms. With such high doses required, maybe 25000IU x 4 doses daily would make a person more compliant even if it was not the best absorbed. And that would be something to consider. Ideally the best source should be predominantly retinol because it is more efficiently absorbed than beta carotene. One molecule beta carotene only 1/6 as effective source of Vit A as retinol. (Harpers Review of Biochemistry). What is the source of your zinc information? I haven't heard that, but would be interested in knowing more. > > > > > > I too have a patient s/p gastric bypass surgery that c/o changes > > in > > > vision and when we checked her reoutine blood work we added on > > Vitamin > > > A and just got results back that she is vitamin deficient (Vit A > > 29). > > > > > > Does anyone know the typical recommendation for repletion?? do > you > > use > > > pills or IM injection and how much??? > > > > > > thanks, > > > > > > Scheckner MS, RD, CNSD > > > Bariatric Nutrition Specialist > > > Montefiore Medical Center > > > Bronx, NY 10467 > > > > > > Quote Link to comment Share on other sites More sharing options...

Guest guest Posted November 28, 2006 Report Share Posted November 28, 2006 Actually, I was hoping someone here had a reliable source. All I've got is an article from the Food and Nutrition Bulletin, vol. 25, no. 1 (supplement 2) © 2004, The United Nations University: Developing Zinc Intervention Programs. I was hoping for something directed specifically to RNY pts. for my files.
