Toilet Positioning and Squatting Stools

Squatting stools (sold under various brand names) are widely marketed on the idea that a more squatted position straightens the anorectal angle and reduces straining. The underlying theory is plausible and long-discussed; the direct research testing it is more limited and mixed than the marketing around these products suggests.

Key takeaways

The theory: sitting on a modern toilet creates a bend in the anorectal angle that requires more straining to pass stool; squatting straightens this angle.
At least one controlled study measuring actual pelvic floor movement found no significant difference between sitting and squatting positions.
A squatting stool is low-cost and low-risk to try, but it isn’t a substantiated fix on the level of fiber intake — treat it as a reasonable low-stakes experiment, not a proven remedy.

The theory behind squatting stools

The anorectal angle is the bend where the rectum meets the anal canal, maintained partly by the puborectalis muscle. The theory holds that a fully squatted position relaxes this muscle more completely than sitting does, straightening the angle and reducing the effort (straining) needed to pass stool — and, by extension, reducing pressure on hemorrhoidal veins.

What the direct research actually shows

This is a case where it’s worth being precise about the evidence. A controlled study measuring actual pelvic floor descent during straining in both sitting and squatting positions, in patients referred to an anorectal physiology unit, found no significant difference between the two positions on this specific measure. This doesn’t fully settle the question — the study measured one specific physiological marker, not overall symptom outcomes, and squatting stools have become popular partly based on separate observations about the angle geometry and self-reported ease of passage. But it means the confident claims sometimes made in squatting-stool marketing outpace what’s been rigorously demonstrated.

What’s more solidly supported

Regardless of exact position, the more consistently supported practical advice is: don’t strain excessively, don’t linger on the toilet, and respond to the urge to go rather than sitting and waiting. These behavioral factors have more consistent support than the specific angle-based mechanism claimed for squatting stools.

A reasonable way to think about trying one

A squatting stool is inexpensive, has no real downside, and some people report it makes bowel movements feel easier — which may be worth trying on that basis alone, even without definitive evidence of hemorrhoid-specific benefit. It shouldn’t be relied on as a primary treatment in place of the more established measures (fiber, hydration, avoiding prolonged sitting).

When to see a doctor

Positioning changes, like other self-care measures, aren’t a substitute for medical evaluation if red flags are present, or if symptoms persist despite consistent self-care.
