Washington: Researchers have developed an oral capsule that vibrates as it moves through the digestive tract has shown notable promise as a non-pharmacological treatment for constipation.
In the pilot study, the vibrating capsule was found to nearly double the weekly bowel movements of patients suffering from chronic idiopathic constipation (CIC) and constipation predominant irritable bowel syndrome (C-IBS).
Yishai Ron, MD, lead researcher for the study and director of Neurogastroenterology and Motility at Tel-Aviv Sourasky Medical Center's Department of Gastroenterology and Hepatology, said despite the widespread use of medication to treat constipation, nearly 50 percent of patients are unsatisfied with the treatment either because of side effects, safety concerns about long-term use, or the fact that it simply doesn't work.
Twenty-six patients took the vibrating capsule twice per week and responded to a daily bowel movement and laxative use questionnaire. All patients initially underwent a two-week preliminary period without the use of laxatives.
Patients reported an increase in spontaneous bowel movements from two to four times per week, as well as a decrease in constipation symptoms, including reduced difficulty in passing stools and incomplete evacuation. The study also found minimal side effects from the capsule use.
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.
