Long Term Post Ops: Caffeine and Vitamin D issues
Hi - as someone who has had serious health issues in the past (but 2 1/2 years post op lap RNY) I am still in close contact with my endochrinologist. When I had labs done at my 2 year WLS app't. my Vitamin D levels were checked. Although it was not flagged by the lab, and not mentioned at my checkup then, my endochinologist noticed the level at my appointment this week. It was pretty low. Low enough to precribed an elevated amount of vitamin D. <br><br> It is worth mentioning that I drink a fair amount of caffeine as a post-op, and my nutrition is rather poor, as I am prone to a huge lack of appetite (this is present with or without caffeine, so don't bother :) LOL. <br><br> With the lab info in hand, I checked out Medlineplus.org, a website highly reccommended by my medical librarian friend. This is what it had to say regarding caffeine and vitamin D:<br><br> http://ods.od.nih.gov/factsheets/vitamind.asp <br><br> Vitamin D and caffeine:<br><br> High caffeine intake may accelerate bone loss. Caffeine may inhibit vitamin D receptors, thus limiting absorption of vitamin D and decreasing bone mineral density. A study found that elderly postmenopausal women who consumed more than 300 milligrams per day of caffeine (which is equivalent to approximately 18 oz of caffeinated coffee) lost more bone in the spine than women who consumed less than 300 milligrams per day [58]. However, there is also evidence that increasing calcium intake (by, for example, adding milk to coffee) can counteract any potential negative effect that caffeine may have on bone loss. More evidence is needed before health professionals can confidently advise adults to decrease caffeine intake as a means of preventing osteoporosis. <br><br> So. Yet another reason to ease up on the caffeine, along with the fact that I suffer monster migraines as was ordered off the junk by neurology the same morning, or else :)<br><br>I should mention that I do get plenty of sun (both outside and tanning), so I don't think that is an issue... this is just an FYI about caffeine.<br> Thanks! -shelli
