Can someone please tell me why I get diarrhea from eating sugar?  And is it always permanent or does the effect fade for most people after a while?  I am nine months out.

Sounds like you are one of the lucky ones!!!

I'm not affected that way by sugar, YMMV.

Hopefully it will change for you.

Sugar is my greatest enemy. It's my downfall. I crave it like a smoker craves cigarettes.

I haven't had the DS surgery, I had RNY five years ago and I still struggle with sugar. I am hoping, hoping, hoping that having the DS will control these awful cravings. Does it? Does the DS procedure help with sugar cravings? It levels out the insulin, right? I think that's my problem. I have too many spikes and drops in my blood sugar. Too many bad dumping and reactive hypoglycemia episodes.

I was able to get my sugar cravings under control before DS, by taking chromium picolinate supplements. It took a few weeks of taking it, but my sugar cravings reduced by about 90%. I hope it works for you!

I think that DS does reduce sugar cravings at least partly because you'll have less grehlin in your system due to having 70% of your stomach removed, but maybe some others will share their experiences with this as well.

Sorry, typo. I meant chromium picolinate. I take three per day (one with each meal) of these:

www.vitacost.com/NSI-Chromium-Picolinate-500-mcg-300-Capsule s

Since they are a dietary supplement rather than a medication, I suspect that I had been deficient before and that's what was causing my sugar cravings--deficiencies can cause odd cravings. For example, people who are very deficient in iron often get intense cravings to eat ice.

I still take them and intend to keep doing so, because if I was deficient before DS, I would certainly be deficient after.

I don't know about that!  I have always been a sugar fiend, and it hasn't changed that much, except that fact that the effects are deadly so I have to rein myself in when I am going to be around other people.

Nothing will change if you don't have the courage to change it!

How much chromium do you take? I was told years ago by my doctor to take chromium for my hypoglycemia. It really helped. I need to start taking it again.

I take 500 mcg. How much do you take?

My cravings for sugar were nonexistant for the longest while...then....once I started eating it, the cravings did come back.   Fortunately, for me, many sugary foods are tooooo sweet nowadays.   I cannot eat milk chocolate or most chocolate bars, but eat dark chocolate a lot.    A chocolate chip cookie or a piece of cake with lots of frostings will make me shiver, they're so sweet.   Other things though, like pie, aren't too sweet.   I have lots of problems with too much sugar - bad gas and diarrhea, so I limit them in my diet for that reason, and also because it will make me gain weight, which it did, over the holidlays!       If I had, say, a donut for breakfast, I'd be so bloated and gassy by lunch that I'd embarrass myself big-time with the results!
