QUESTION: "I take medications for acid reflux. How is this going to affect my bones?"
DR. MARIE SAVARD: I'm getting this question all the time. There is a lot of research that shows that's exactly the point. The more you take, the stronger the medication, it lowers your bone density and raises the risk of fracture. Why is that?
It turns out that when you block all that acid, which is important, you're not absorbing important vitamins, including calcium.
[Medications such as] Prevacid, Prilosec, Nexium, those are strong and they're meant to be taken for short periods of time -- six to eight weeks. So if you have an ulcer or a bad reflux, that's fine. But beyond that time, use lifestyle and other ways to kind of get rid of the heartburn.
... It's not the magic bullet to get rid of that heartburn and indigestion when you ate too much and drank before you went to bed. ... That has to be lifestyle. Don't eat late at night, minimize the alcohol at night. And if you need it for short periods, that's fine. Or try the over-the-counter antacids or even Pepcid AC. They're milder, don't block as much acid.
There's a rare condition, Barrett's Esophagus -- that really does raise your risk of cancer. In that case, maybe you need lifelong medications. But, then, maybe you need to double up on calcium and vitamin D with it.
Dr. Marie's advice? Acid reflux medications are short-term solutions.
QUESTION: "I'm interested in finding out more about the injectable contraceptive Depo-Provera. Does it work the same as the pill or is it completely different?"
SAVARD: The injectable form, obviously, is a shot. It lasts for three months and I guess that's the easy part of it. And the active ingredient is progestin. ... It's very similar to what's in birth control pills. The difference is this. The difference is, there's no added estrogen. Estrogen was put in birth control pills to kind of even out the lining so that you would have a more even [menstrual] flow every month.
... It's absolutely just as effective. The progestin is the active ingredient in all hormone pills and it works by thinning the lining of the uterus so that you can't have a successful pregnancy, and it also stops an egg from forming every month.
