The purpose of this study is to see if chewing sugarless chewing gum alters the time it takes for a capsule endoscopy to travel through the stomach and small bowel, and to see if more/less capsule endoscopes reach the large bowel.
The subjects will include patients already referred to us for a capsule endoscopy (CE) in this unit. We have calculated how many patients we need from small bowel transit times from the last 100 patients who had a CE at our centre. We will include 122. These will be randomly divided into two groups. The patients (chew chewing gum) and the controls (do not chew chewing gum).

Patients will be randomly divided into 2 groups, one subject group (these chew gum) and one control group (these do not chew gum). The subjects will have to chew Trident sugarless chewing gum for 20-30 minutes every 2 hours, all together 4 times at t=0 h, t=2, t=4 and t=6 h.
The control group will not chew chewing gum while undergoing capsule endoscopy
