Raising your knees above your hips and leaning slightly forward is the most effective way to sit on the toilet when you’re constipated. This position mimics a squat, which straightens the path between your rectum and anal canal so stool can pass with less straining. A small adjustment in how you sit can make a surprisingly big difference.
Why Standard Toilet Posture Works Against You
When you sit upright on a standard toilet at a 90-degree angle, a sling-shaped muscle called the puborectalis wraps around your rectum and kinks it, almost like a bent garden hose. This kink exists for a good reason: it keeps you continent throughout the day. But when it’s time to go, that same kink creates resistance you have to strain against.
In a squatting position, your hips flex to roughly 35 degrees relative to your torso, and that muscle relaxes. The angle between your rectum and anal canal opens to about 126 degrees, creating a much straighter exit path. The result is smoother evacuation with significantly less pressure. This is why squatting cultures historically have lower rates of constipation and hemorrhoids. You don’t need to abandon your toilet to get this benefit, though. You just need to change your posture on it.
The Step-by-Step Sitting Position
The American Physical Therapy Association’s pelvic health division recommends a supported squatting position that you can do on any standard toilet:
- Place a footstool in front of the toilet and rest both feet on it, hip-width apart. This raises your knees above your hips, which is the single most important change.
- Lean forward slightly from your waist so your torso tilts toward your thighs. Rest your elbows on your knees for support.
- Keep your back relatively straight rather than hunching. Think of tilting your whole trunk forward, not rounding your shoulders.
If you don’t have a footstool, sit forward comfortably on the seat and keep your heels flat on the floor. Lifting your heels while sitting actually tenses the pelvic floor muscles, which is the opposite of what you want. If you only have a small stool that can’t fit both feet, place it under your left foot. This still helps open the anorectal angle, though not as effectively as elevating both feet.
Choosing the Right Footstool Height
Toilet footstools typically come in 7-inch and 9-inch heights. A 7-inch stool works for most people and is the better starting point, especially if your toilet is a standard height (14 to 16 inches). If you’re shorter, more flexible, or have a “comfort height” toilet (16.5 inches or taller), a 9-inch stool will bring your knees to the right position. The goal is simply knees above hips. You can test this before buying anything by stacking a few thick books or using an overturned bin.
How to Breathe Instead of Strain
Positioning is only half the equation. The way you breathe on the toilet matters because your diaphragm and pelvic floor move together like a piston. When you inhale, your diaphragm drops, your abdominal organs shift downward, and your pelvic floor naturally sinks and relaxes. When you exhale, everything rises and contracts again. Holding your breath and bearing down (the Valsalva maneuver most people default to) locks everything tight and works against the relaxation you need.
Instead, try this: once you’re in position, take a slow, deep breath into your belly. As you exhale, let your abdomen gently bulge forward and allow the pelvic floor to release downward. Think of it as “breathing into your belly” rather than pushing. Some pelvic floor therapists describe this as making a low “moo” or “shh” sound on the exhale, which naturally engages the diaphragm without clenching. Repeat this a few times. If nothing happens within a couple of minutes, get up and try again later.
Don’t Sit Too Long
Cleveland Clinic gastroenterologists recommend spending no more than five minutes on the toilet per attempt. Sitting longer than that, especially on a toilet seat that puts pressure on the veins around your rectum, increases your risk of hemorrhoids and can worsen pelvic floor dysfunction over time. If you’re not feeling any urge after a few minutes of good positioning and breathing, stand up, walk around, and try again when the urge returns. Bringing your phone into the bathroom is one of the biggest contributors to prolonged sitting.
Other Habits That Help
Positioning and breathing are your best tools in the moment, but a few daily habits reduce how often you end up straining in the first place. Drinking enough water keeps stool soft. Fiber from fruits, vegetables, and whole grains adds bulk that’s easier for your colon to move along. Physical activity, even a daily walk, stimulates the natural contractions of your intestines. And responding promptly when you feel the urge to go, rather than delaying, prevents stool from drying out in the rectum.
Many people find that their strongest urge comes 20 to 30 minutes after eating, especially after breakfast. This is the gastrocolic reflex, a wave of colon activity triggered by food entering your stomach. Timing your bathroom visit to this window, then using the squat position, gives you the best chance of an easy, complete bowel movement.
Signs Something More Is Going On
Occasional constipation that responds to positioning changes, more water, and dietary fiber is normal. But constipation that lasts longer than usual, alternates with diarrhea, or comes with rectal bleeding, blood in your stool, black stools, unexplained weight loss, or significant abdominal pain points to something that positioning alone won’t fix. These symptoms warrant a conversation with your doctor to rule out conditions that need specific treatment.
