Has anyone had any malabsorption issues? I’ve had trouble with sugar (I’m not diabetic) for a while. I get very ill from eating any and have getting more and more sensitive. I have a group of doctors trying to figure out my problem.

I think in a way we all have that due to having diarrhea, when we have diarrhea, we do not absorb everything unfortunately.
It is pretty normal for people to have sensitivity to sugar, particularly fruit sugars (fructose), particularly as we get older. After colectomy and our gut is adapting, you may not absorb everything. The key is smaller portions and combining different types of food. If you are avoiding sugar by eating/drinking things with sugar substitutes, be sure to avoid sugar alcohols. These are not digested and cause diarrhea. They include sorbitol, malitol, mannitol, etc.. Sucralose, stevia, and aspartame are OK, unless you have a specific sensitivity.

It’s not sugar insensitivity, it’s sudden inability to tolerate any sugars. They make me violently ill. Vomiting, dizziness, inability of my legs being able to support me. It’s all very strange, my doctors are baffled so far.
Wow! That is truly bizarre! You may have to test one sugar at a time to see which one offends. If it is all sugars, you may need to get a referral to a pancreatic specialist, as it sounds like a form of exocrine pancreatic insufficiency that is selective for amylase. Also, pancreatitis needs to be ruled out. This totally is NOT normal!
