Here I go again!
To respond to some of your comments on this statement, I think it's better to create a new post, then all can see and the thread doesn't get lost.
It is true that absolute definitive research is lacking but there is evidence that use of PPI's for more than seven years is associated with an increased risk of osteoporosis related fractures. The mechanism is not clear but it is thought that gastric hydrochloric acid is important for absorption of calcium .Other papers say that absorption of iron, Vit B12 and magnesium are also compromised because of the reduced stomach acidity. It is commonly accepted that iron is absorbed in the ferrous Fe2+ form rather than ferric Fe3+, hence the advice to take iron with fruit juice or vit C. Also, PPI's do not only affect the parietal stomach cells which produce the HCl acid. Proton pumps exist in all cells including osteoclasts and osteoblasts.
The manufacturer's data sheet and patient information leaflet also states that "taking a PPI for longer than one year may slightly increase your risk of fracture in hip, wrist or spine".
So taking all into account and especially since the drug company is saying the same thing, I feel it is reasonable to avoid PPI's if also taking steroids. Why compound the risk of bone loss?
