well, you COULD become malnourished and vitamin deficient, but taking supplements prevents that. If you don't keep on top of your supplements, then yes - that could be a problem. That's why it's so important to take your vitamins after RNY (and DS, too)

I've never heard of anyone throwing up after one bite of a Reese cup or anything with sugar. About 30% of RNY'ers dump, but that can be prevented by not eating a bunch of sugar at one sitting (and I'm not talking about one bite of a Reese's - we're talking like a cup or more of ice cream, for example). Most dumpers can tolerate some sugar in one sitting - just not a lot. And about 70% of us never dump at all. I never have. Unfortunately, I could eat an entire PINT of ice cream with no trouble at all, unfortunately (unfortunately because I was hoping I WOULD dump to keep me from eating too much sugar!)

Also, dumping generally involves diarrhea, abdominal cramping, heart palpitations, and dizziness. Vomiting can happen, but it's not as common because dumping is caused by too much sugar entering your small intestine too quickly, and the intestines go into overdrive trying to deal with it. So the "action" is in the intestines rather than the stomach.

food restrictions are limited the first month or so, then gradually they drop off until about the six-month mark, when there are no restrictions at all. You should have no problem finding what you're supposed to eat those first few weeks, even living in a small town.

if you want to see what actual RNY patients eat, then lurk on the RNY menu thread for a few days. That should give you a realistic idea.

P.S. LOTS of people have revised from lap band to either RNY or VSG. In fact, there are a few of us on the RNY menu thread *****vised from lap band. I really encourage you to check out that thread if you want a lot more insight into RNY from people who've had it - some of us are many years out and have been on the site for years.

i have the lapband and they want to do a gastric bypass now because of acid and gaining weight. i am very nervous regarding it i have had people say after the bypass you can become vitamin deficiency and malnourished. i am on the fence . i should also say they just found out i have hashimotos and gained 50 pds. people are telling me tha t if you were to take a bite of a reeses pb cup you will get sick and throwup if you eat anything with sugar. i am worried i live in small town that doesnt have a big grocery store so im limited. and i dont look at back of package on things. please any help or insite would be wonderful.

I just happen to be seeing this post now.

I just wanted you to know that someone cared and if you could post an update if you feel comfortable, that would be great.

I am so sorry you are being tested like this.

huge hugs, Lisa

I was told I probably have it after every other potential cause was ruled out (my glucose level was normal at the time I had the work-up, so that wasn't suspected at first). My PCP recommended I eat something every 3-4 hours - a protein was the best option - and if I ate a carb, to be sure to pair it with a protein. It seems to have solved the problem - although your case might be more severe than mine.

I've just been diagnosed with reactive hypoglycaemia and am trying to get a hold of the condition via diet. What i'd like to know is how many members have this condition post rny surgery and how they deal/cope with the condition. Mine tends to be severe and the symptoms are very hard to control.

If anyone is willing to share their experiences and how they have been coping i would greatly appreciate it.
