1 Artificial Sweeteners Artificial sweeteners and sugar alcohols, particularly mannitol and sorbitol, can cause diarrhea in some people. 2  Mannitol and sorbitol linger in the stomach, Schiller says, which can result in bloating and diarrhea.
The burning question, of course, is whether artificial sweeteners can truly make humans sick and fat. Segal thinks they probably do, at least in some cases. He and his team analyzed a database of 381 men and women and found that those who used artificial sweeteners were more likely than others to be overweight. They were also more likely to have impaired glucose tolerance.
