Use of a Squatting Assist Device in Patients With Constipation

Constipation is a very common problem. Western style toilets that are nearly universal in the United States require the person to sit on the toilet. However, results from uncontrolled studies suggests that a squatting posture (as prevalent in many foreign countries) may be better at facilitating evacuation compared to a Western style commode. One uncontrolled, unpublished study suggests that a footstool improved bowel symptoms in nearly 98% of 153 constipated participants. Hence, the investigators propose to evaluate the benefits of a footstool on symptoms and anorectal functions in constipated patients. Hypothesis: the regular squatting assist device (7 inches) but not a sham device (2 inches tall) will improve symptoms of constipation.

Patients on higher doses or on other anticholinergics are eligible to participate if they can discontinue their medication at least 3 days (72 hrs) before the date of screening and are willing to stay off them till the study is complete. * Current use of laxatives (MiraLax, Ex-lax, senna, herbal supplements), linaclotide, lubiprostone, and prucalopride to treat constipation- patients using these medications will be eligible to participate if they can discontinue the medication at least 3 days (72 hrs.) before the date of screening and are willing to stay off them till the study is complete.
