For a year I have been taking Prevacid, which is heavy duty Reflux medication, in an attempt to heal a lesion on my esophagus (known as Barrett's Esophagus). Apparently it worked, the doctor said to see him in three years.
What I found out directly, by looking this stuff up on the net, is that if you take it for over a month you are at risk for osteoporosis. it you take it for longer than a year and don't have osteo, you will probably get it, because this thing is a proton pump inhibitor, and inhibits calcium from entering the body. sigh.
So you take twice as much calcium and hope. I already have osteo, so this year has been one of Being Careful and keeping my fingers crossed.
I have since stopped the Prevacid, partly because of that, but partly because I was on a diet for a year, a careful, serious diet, and gained four pounds. Aha, I thought. Maybe it's the Prevacid, mucking about with my metabolism. In the two months since I stopped taking it, on the same diet, I have lost seven pounds. Aha, I thought. Lookit that. And of course the weight gain distorts the esophagus and makes the Reflux worse.
It has been a year of trying to balance two very different problems, each of which counters the other, since calcium needs stomach acid to work properly, and prevacid does it's very best to reduce the same acid to do its job properly. The people I feel sorry for in all of this are the women who took this stuff when it was being tested, some of them in their forties and fifties at the time, and suddenly found themselves looking at the rest of their lives with osteoporosis in it.
