Not all ingredients in diet gums are safe because some contain sorbitol, which can cause pain, unexplained weight loss and chronic diarrhea, explains WebMD. Excessive consumption of diet gums can lead to increased levels of sorbitol, which is a sugar alcohol that has a poor absorption in the body.
Doctors advise patients to use diet gums to help in cutting calories and avoid cravings, explains WebMD. Alternating gum with a piece of hard candy helps prevent bloating, which occurs due to swallowed air that results from chewing gum regularly. It's advisable to limit beverages and foods that contain sorbitol when using the diet gum.
