Getting sick after eating sweets/sugar?

This happens to me as well and did throughout high school mainly if I had Starbucks. I was diagnosed as reactive hypoglycemic so my body works adversely with sugars. Almost instantly after consuming a sugar I will sky rocket and then crash below normal average levels. I wish my brain would get the memo and stop craving it haha! It can be very unpleasant and resemble the symptoms of irritable bowel syndrome or IBS I spoke with my doctor about it and we are currently working on tests to see if I really have IBS or if it's just a glycemic issue. The GI symptoms became pronounced after my first child so the doctor seems to think instead of IBS it's more of a lactose intolerance mixed with the hypoglycemia (but I'm not so sure). Often I have found what can help is to take two tums it settles my tummy enough to take the nausea away and then munch on some crackers and pound water. Some times our minds get carried away when we don't feel well but that's understandable it means you value and enjoy life so don't be discouraged to speak when you think something's not right. You are your care taker. No one else knows you like you. Bodies are forever changing. I hope this helps. Take it easy.

Have you noticed a pattern with regards to homemade vs. store bought sweets? If it happens primarily from store bought sweets, I wonder if maybe you have a sensitivity/allergy to a preservative or something in therm?

I just ate some ice cream, not a lot, and it hurts really bad. It is also like I can feel the sugar rushing in my veins. The thing is, I don't eat the kind of sugar laden sweets most people do. I think I'm just too sensitive to sugar, I think I'll talk to my doctor about it.

You might want to check for lactose intolerance, too. Speaking as someone who's lived all her life with either hypoglycemia or hyperglycemia, I can count on one hand the number of times I was nauseated with the effects of sugar. However, my grandmother was lactose intolerant and it tore her insides up every time she ate ice cream (she could tolerate the little bit of milk or cream in her coffee pretty well). She lived 97 years and never did give up the stuff . . .

I get bad nausea if I have too much sugar. I had some icing on a donut today and it made me sick all morning with intense nausea. Normally I avoid donuts, it was just a one-off event. Sometimes I just get brain dead and go back to eating like a normal person.

Food puts me to sleep. So now I have protein shakes and just try and not eat much at all until supper and that has helped me stay awake during the day, otherwise I take a 2-3 hour nap daily. I work from home so that's okay, but if I have to drive in the afternoon it's dangerous because I'm so tired. I'm an insomniac and have been treated for that for years so when I started falling asleep constantly this spring my doctor was really surprised. They're not sure what is wrong with me but maybe reactive blood sugar. I have more testing coming up. I seem to be able to get away with about 200 calories. If I go above that I might drop to sleep. *sigh*

Nope, I never have a problem with sugar. I have done very low carb ketogenic diets in the past for months at a time. When falling off the wagon and eating something sugary, it was blissfully delicious with no adverse reactions whatsoever. Now WHEAT on the other hand is a different story. I gave up wheat because it was aggravating my autoimmune issues, but I never had a problem with how my belly felt after eating wheat. Now that I don't eat wheat on a regular basis anymore, if I do make an exception and have a small piece of wedding cake, I get a horrible bellyache. I've heard tell that it's because if you're not eating wheat your body temporarily stops making the enzymes that properly digest the wheat but I don't know if that's a myth or not.

I have the same problem...I just had two pieces of Dove chocolates and no more then 15 minutes later I feel light headed and nauseous. Sometimes it's accompanied with stomach pain. I get so tired of feeling sick all the time.

I'm also sick all the time... did you know that refined sugar is actually toxic to us?

I was told I am carb sensitive, meaning the refined, simple carbs like sweets, are rapidly digested, lifting your blood sugar quickly but then rapidly "dropping" you back down. )

^^^^this...what this is describing is what is referred to as "dumping" in the gastric bypass world but it can happen to people who have not had the surgery as well. It's just VERY common for those of us who have had it, my surgery was over 9yrs ago and this still happens to me with ice cream being the worst culprit but even a carb heavy meal can bring it on. In addition my heart will race, I'll get sweaty, shaky, dizzy...it sucks! You would think that would deter me huh?!

No, it's not. If you're sick, see a doctor.

Sorry for coming in late to this discussion. I was recently diagnosed diabetic and started reading A LOT. I came across this article and it reminded me of one of my coworkers. She seems to know quite a bit about it.

Sugars, sweets, fruits, make her sick. It's happened since she has been a child and has learned to live with it. What is happening is glucose intolerance. It is a lack of enzymes that break down the sugars glucose, sucrose, and fructose. The body is treating it like a poison causing sickness and vomiting. She has Congenital Sucrose/Isomaltase Deficiency. It can also be called Sucrose/Fructose Intolerance. She said some cannot even have lactose, which she is happy she does not have as she likes to drink milk. She is careful what she eats. She can have breads but not raisin or banana bread because of the fruit. She can't have pizza with tomato sauce but can have a white-sauce pizza. There are enzyme supplements that doctors can prescribe but it doesn't work for everyone, she doesn't take them.

I hope this helps someone.

I am doubt anyone may see this as it is such an old thread but I have for years and years dealt with stomach pain and nausea after sugar consumption. I always just dealt with it and avoided sugar first thing in the morning and the like to help reduce the symptoms. Then when my daughter, who is now 16 was born, we noticed that she was even worse than me. She could have a small bowl of ice cream or a brownie and she had to run to the bathroom and throw up. She is also a sugar addict and would sneak candy whenever she could as a toddler and she would spend weeks where she would throw up every day. As she has gotten older she is much better and self control and it has gotten better. I always thought it was just us but now I feel like I have a direction to head in and maybe we can finally get some answers. Thank you to everyone who commented and added to this post and especially to the original poster.
