For a posture that may make passing stool easier, sit on the toilet with the feet securely supported and lean the upper body slightly forward. A footstool that raises the knees a little above the hips may also help. This article introduces bowel-movement posture when safe sitting is possible, including for people who wear diapers, and equipment that supports that posture.

Sitting for easier bowel movements

Resting the elbows lightly on the thighs can help stabilize the upper body. Sit with the feet on the floor and lean forward only as far as comfortable. For someone with stable posture, a footstool can also raise the knees a little above the hips.

Posture and the angle between the rectum and anus

When lying on the back, the passage from the rectum to the anus is bent, which can make passing stool difficult. Stool consistency and general health, as well as posture, affect the ease of bowel movements.

Sitting on the toilet and leaning slightly forward changes the angle between the rectum and anus and may make passing stool easier. Raising the knees above the hips with a footstool can also help reduce straining.

Why bowel movements can be difficult while lying down

Lying down prevents the seated posture used on a toilet and may make bowel movements difficult. Consult healthcare or care professionals if constipation persists or laxatives are used. If there is soft stool or diarrhea, also review diaper selection and changing methods.

The importance of sitting on the toilet for bowel movements

Even when someone wears diapers, sitting on the toilet for bowel movements may be considered if they can reach it safely.

Refitting tape-fastened adult diapers while standing at the toilet can be demanding for both the person and caregiver. If possible, consider pull-on adult diapers or similar products and having bowel movements while seated on the toilet.

If the person cannot reach the toilet, consider a bedside commode or bedpan.

Equipment that stabilizes bowel-movement posture

Some people find maintaining a forward lean difficult. Avoid forcing a posture change, and use support rails or other assistive equipment as needed.
