The single most effective thing you can do to stop straining on the toilet is change your sitting position so your knees are higher than your hips. This straightens the pathway stool travels through, letting gravity do most of the work. But positioning is only one piece. Diet, timing, breathing technique, and hydration all play a role in making bowel movements easier.
Why Straining Happens in the First Place
Your body has a natural kink built into the system. A sling-shaped muscle wraps around your rectum and pulls it forward, creating a bend (called the anorectal angle) that helps you stay continent throughout the day. When you sit on a standard toilet, that angle stays relatively tight, around 80 to 90 degrees. You’re essentially trying to push stool around a bend, which requires more effort and pressure from your abdominal muscles.
When you squat, that angle opens to about 100 to 110 degrees, and the rectal canal straightens significantly. Research comparing sitting, hip-flexed sitting, and squatting found that squatting produced the straightest pathway and required the least abdominal pressure to pass stool. The problem is that most Western toilets aren’t designed for squatting, so you need workarounds.
Fix Your Position on the Toilet
Place a footstool (6 to 9 inches tall) under your feet so your knees rise above your hips. Lean forward slightly and rest your elbows on your thighs. Let your belly relax completely rather than sucking it in. This approximates a squatting posture on a standard toilet, opening up the rectal angle without needing to balance over a squat toilet.
If you don’t have a footstool, a stack of books, a small trash can turned on its side, or even rising onto your toes can help. The key measurement is getting your thighs closer to your chest. Many people notice an immediate difference the first time they try this.
Use the Right Breathing Technique
Most people strain by taking a big breath, closing their mouth, and bearing down hard. This is counterproductive. Holding your breath and pushing with a closed mouth tightens your pelvic floor muscles, which are the very muscles that need to relax to let stool pass.
Instead, try this three-step approach recommended by pelvic health specialists:
- Breathe low. Inhale into the lower half of your lungs, keeping your mouth slightly open the entire time.
- Bulge your belly. Gently push your lower abdomen outward. This creates downward pressure without clenching the pelvic floor.
- Push into your waist. With your mouth still slightly open and breathing normally, direct pressure outward through your waist and lower belly, not downward through your bottom.
The open mouth is the detail most people miss. It’s nearly impossible to bear down dangerously hard when your mouth is open and you’re exhaling. Think of it as a slow, controlled push rather than a forceful strain. If you find yourself holding your breath or turning red, reset and start again.
Time It With Your Body’s Natural Signals
Your digestive system has a built-in trigger called the gastrocolic reflex. When food enters your stomach, your colon receives a signal to start moving things along and make room. This reflex is strongest in the morning and right after meals. Sitting on the toilet 15 to 30 minutes after breakfast, when the reflex is at its peak, gives you the best chance of a bowel movement happening with minimal effort.
Consistency matters here. Establishing a daily routine at the same time trains your body to expect it. Over a few weeks, many people find their urge to go becomes more predictable. Equally important: when you feel the urge, don’t ignore it. Delaying a bowel movement allows the colon to absorb more water from the stool, making it harder and more difficult to pass later.
Soften Your Stool With Fiber and Water
No amount of positioning or breathing technique will help much if your stool is hard and dry. Current dietary guidelines recommend 14 grams of fiber for every 1,000 calories you eat. For most adults, that works out to roughly 25 to 35 grams per day. Most people fall well short of that.
The easiest way to increase fiber is to add it gradually. Beans, lentils, oats, berries, broccoli, and whole grains are all high-fiber options. Increase your intake slowly over a week or two, because a sudden jump in fiber can cause bloating and gas. Pair every increase in fiber with extra water. Fiber absorbs fluid to bulk up and soften stool. Without enough water, adding fiber can actually make constipation worse.
You can gauge whether your stool is at a healthy consistency using the Bristol Stool Scale, a simple visual chart used in clinical practice. Types 3 and 4 on that scale, shaped like a sausage with some cracks or a smooth, soft snake, are ideal. They’re formed enough to hold together but soft enough to pass easily. Types 1 and 2 (hard lumps or a lumpy sausage) suggest dehydration or slow transit, meaning stool has spent too long in the colon and lost too much water.
When Stool Softeners or Laxatives Help
If diet changes alone aren’t enough, over-the-counter options can bridge the gap. Stool softeners work by pulling water into the stool itself, making it softer and easier to pass. They’re gentle enough for daily use in the short term and are commonly recommended after surgery or for people with hemorrhoids who need to avoid straining.
Osmotic laxatives take a slightly different approach. They draw water into the colon, which both softens stool and stimulates the bowel to move. These typically take about eight hours to work, so many people take them at bedtime for a morning result. Neither type should become a long-term crutch without understanding why you’re constipated in the first place, but they’re safe and effective for occasional use.
What Chronic Straining Can Do to Your Body
Straining isn’t just uncomfortable. Repeated high pressure in the lower rectum is one of the primary causes of hemorrhoids, which are swollen blood vessels inside or around the anus. Internal hemorrhoids can cause painless bleeding (bright red blood on toilet paper or in the bowl). External hemorrhoids are more painful, especially if a blood clot forms inside one, causing sudden severe pain and swelling.
Chronic straining also increases the risk of anal fissures, which are small tears in the lining of the anus that cause sharp pain during and after bowel movements. Over years, repeated straining can weaken the pelvic floor muscles, potentially contributing to issues like rectal prolapse. Most of these problems are preventable by reducing the pressure you generate during bowel movements.
Signs Something More Serious Is Going On
Occasional straining after a low-fiber day or during travel is normal. But certain patterns warrant a conversation with a doctor: constipation lasting longer than three weeks, rectal bleeding or blood in your stool, black or tarry stools, unexplained weight loss, persistent stomach pain, or unusual changes in the shape or color of your stool. These can signal conditions that go beyond simple constipation, and rectal bleeding in particular should never be assumed to be hemorrhoids without evaluation.
