An oral capsule that vibrates as it moves through the digestive tract has shown notable promise as a non-pharmacological treatment for constipation, according to new research. The capsule, which houses a small engine inside, is programmed to begin vibrating six to eight hours after swallowing. The vibrations (mechanical stimulations) cause contractions in the intestine, which help move stool through the digestive tract.
