Magnesium Oxide for Constipation

I have suffered from constipation all my life. I do everything you are supposed to do to have healthy bowel movements...I am a vegetarian,mostly raw, and so consume fibre, fibre, fibre, I drink at least a gallon of pure water every day, I run, walk, do yoga, I give myself time to go, do abdominal massages....everything. A few years ago, despite all this, I did not have a bowel movement for 27 days. The pain was horrible. Everyone asks me why I let it go so long. I was trying all the usuual remedies and giving each of them a day or two to work, fully expecting them to. I tried cascara, prune juice, aloe vera, senna, all in large doses, I tried an enema...and got zero results, except for more and more pain. On the 27th day, crying and throwing up, unable to eat or drink, I visited the emergency room. My bowel was obstructed. Unwilling to undergo surgery, I went home, crying, and checked the internet, paid 30 bucks for a poorly written four page "e-book", and am eternally grateful that I did! It said to take magnesium oxide. Simple. It would cure constipation forever with daily dosage. I started that night with a massive dose...three 300mg capsules every two hours all night long. In the morning, I moved a tiny, dry piece, but was grateful even for that....the blockage was moving. The next day, I passed seven huge easy movements...each one a foot long. I will never never again go a day without magnesium oxide. I take 400-600 mg/day before bed and have not missed a day since.

Anyone who has ever not had a movement for more than a few days will attest to how awful it is....this cure is so simple. Magnesium oxide has the most dramatic laxitive effect, much more so than citrate.

Is it cured or are you still taking it? Is this an actual cure for constipation or are you treating it indefinitely?

Too much fibre constipates. Even raw veg. You need fats/dressing. I know from having been obsessed with fibre and avoided fats as a young woman, thinking it would keep me slim.

This post helped me thru a crisis - fortunately it wasn't a 27-day crisis! I took at least 1000mg Mg oxide one night and finally started going again. Now I'm a daily Mg oxide user to stay regular. I need 800mg/day and sometimes as much as 1200mg. Works better for me than citrate or glycinate. Glycinate keeps me awake and a bit jittery.
