I have no trouble eating yogurts, cheeses, most candies and fruits; drinking milk, sugar in coffee or tea.

But; big but, I cannot eat ice cream, frozen yogurt, fruit smoothies, cake and chocolate in bar form.

I know that some of these things are no-nos. But, in the off times that I eat them, I get very sick. I get sweaty, dizzy, have trouble concentrating and finishing sentences. I feeling nearly poisoned.

What confuses me is that it is not consistent after 14 years.

Does anyone else have similar issues?

I think, from your list, it's the sugar + fat combo that's bugging you.

Yogurt is often fat free

cheese is sugar free

candy might be fat free

fruit is fat free

milk .. depends on the type.. but if you tolerate it, then lactose isn't the issue

sugar in coffee and tea is fat free

----------------------------------------------

ice cream... sugar + fat

frozen yogurt... and smoothies... not sure.. if they are both fat free, then maybe it's the.... cold?

cake.. sugar + fat

Chocolate.. sugar + fat

Some patients experience a condition called reactive hypoglycemia. It sounds like you are experiencing periods of low blood sugar after you consume foods high in sugar content. Here is a link. https://www.ridgeviewmedical.org/services/bariatric-weight-loss/enewsletter-articles/reactive-hypoglycemia-postgastric-bypass You can search the internet for more information on this condition.

You'd think she'd get hypoglycemia from candy too though.. (not saying it ISN'T a blood sugar problem, just that it's weird ).

Personally I can taste the baking soda in cakes and the like, so then I start thinking maybe there is another ingredient in the second list that you have developed a sensitivity to (my daughter is sensitive to vanilla! Can you imagine?)

I was kinda assuming you are dumping.. but maybe taking a blood sugar reading when you feel that way could answer whether it's the reactive hypoglycemia. (The other way to tell, if you don't have a monitor, is to see if you feel better after you eat something).
