I need to relieve my chronic constipation since surgery.  My nurse practioner told me to take magnesium but she didn't say how much.  Anyone know how much to take?  Thanks.  Carol

I had chronic constipation for 11 years. I tried: more fiber, less fiber, soluble fiber, insoluble fiber, no fiber, both fibers, stool softeners, Smooth Moves & Correctol teas and Metamucil wafers, together, apart, more water, less water, cut out anything bu****er (and protein), senna, cascara sagrada, everything one could possibly try until I was basically dependent on enemas for 3 yrs.

Miralax helped the stool be passable. It was rx and finally became generic, so went from $80 for 3 months to $20 for 3 months. Now it is OTC, but is about $8 for 5-6 servings. If you can get the rx, it is much cheaper, safe, daily, for life, according to my GI doc.

The stool softeners are store brand equal to Colace, not PERI-colace.

Word was that magnesium citrate was such a great thing. This is pills, not the green bottle, so I tried it and nothing happened, and so I kept increasing it. What DID happen is that my foot and leg cramps ceased. So, I kept doing that and tried magnesium oxide. This is small, cheap, found anywhere, like drug stores. And finally, it worked. Mine are 500 mg and I take 2.

My final formula:
1 serving MiraLax (rx) *
4 stool softeners at night
1 mag ox with lunch, 1 with dinner

In the morning, hot beverage first thing on empty gut

This has worked for several years yrs now.

* MiraLax was rx only until the end of 2007, and is now generic by rx. The original name brand is available at drug stores at about $20 for a large bottle. You might want to try one first, taken daily, at about the same time. If it solves the problem, then ask your doc for rx. It is NOT a laxative. It is safe, daily, taken for life, per 4 doctors I've asked. It was a pediatrician who introduced me to it. My rx plan allows me to have 6 of those big bottles every 3 months for $20. Check with your doc and your insurance to see if it's beneficial to buy it by rx. BTW, my doc writes for 2 servings per day, because they might SAY there are 30 servings per bottle, but somebody can't count. Me or them? I use only one, but if I spill or get too much, I still have enough to last til next refill.


You have to adjust your dose to fit YOU. I take 2. That's of what is available to me, so I can't cross it over to other brands,

P.S.  My year + long absence has NOTHING to do with my WLS, or my type of WLS. See my profile.
