Sorbitol, one of the most commonly used artificial sweeteners in chewing gum and candy as well as liquid medications, is poorly absorbed in the intestines, giving it the qualities of an osmotic laxative at higher doses….
….The authors say consumers are generally unaware of the possible side-effects of sorbitol, even though details are included in the small print of foods containing it. When consumers have gastronomical problems they are unaware that they may be caused by the laxative effects of sorbitol.
The authors conclude that sorbitol consumption may not only cause chronic diarrhea and functional bowel complaints, but also significant unplanned weight loss of about 20% of body weight.
Any investigation of unexplained weight loss should include a detailed dietary history with regard to sorbitol-containing foods.
Also known as glucitol, sorbitol is a sugar alcohol. The body metabolizes it slowly. It is obtained by reduction of glucose changing the ether group to an addition hydroxyl group – hence the name sugar alcohol.
Sorbitol can be found in cough syrups, sugar free mints, chewing gum, diet foods, diet drinks and ice creams. Sorbitol occurs naturally in some stone fruits and berries from trees of the Sorbus genus.
Sorbitol is also used as a non-stimulant laxative. It is either an oral suspension or a suppository. It draws water into the large intestine, stimulating bowel movements.
Most people don't consume, eat, chew 15+ mints gums etc...Daily BUT its something to consider if you start having gastrointestional issues
