If you’re struggling to have a bowel movement, the fix usually comes down to a combination of positioning, timing, and a few simple habits. Most people deal with this at some point, and the solutions are surprisingly straightforward. Here’s what actually works, starting with what you can do right now.
Fix Your Position on the Toilet
The way you sit on a standard toilet isn’t great for pooping. When you sit upright at 90 degrees, the muscle that wraps around your rectum only partially relaxes, creating a kink that narrows the passage. Your anorectal angle in a normal sitting position is about 80 to 90 degrees, which means your body is essentially working against a bend.
Shifting into a squat-like position opens that angle to roughly 100 to 110 degrees, straightening the rectum so stool can pass with less straining. You don’t need a squat toilet to get this benefit. Place a small stool or a stack of books under your feet so your knees rise above your hips, then lean forward slightly with your elbows on your thighs. This mimics a squatting posture and makes a noticeable difference for most people.
Use Your Body’s Natural Timing
Your colon is most active in the morning, especially after eating or drinking something warm. This is driven by the gastrocolic reflex, a wave of contractions triggered when your stomach stretches with food or liquid. Coffee is particularly effective at kickstarting this process. Research published in the journal Nutrients found that coffee increases the urge to defecate in at least a third of the population, and the effect kicks in as quickly as four minutes after drinking it. Decaf works too, since the trigger isn’t just caffeine.
If you can, build a routine around this window. Eat breakfast, have your coffee or a glass of warm water, and then sit on the toilet for five to ten minutes. Don’t force anything. The goal is to let your body’s reflexes do the work. Over time, this routine trains your colon to expect a movement at a predictable time.
Try an Abdominal Massage
Gently massaging your abdomen can physically move things along by stimulating the wave-like contractions that push stool through your colon. The technique known as the “I Love U” massage follows the path of your large intestine. Start on your lower left side and stroke downward (the “I”). Then trace an upside-down “L” from your upper left across to your upper right and down. Finally, trace an upside-down “U” shape starting from your lower right, up to your upper right, across to your upper left, and down your left side.
Use firm but comfortable pressure with your fingertips, and repeat for about five to ten minutes. A meta-analysis of studies on abdominal massage found it effectively increases the frequency of bowel movements and softens stool by shortening the time waste spends in the colon.
Eat the Right Kind of Fiber
Not all fiber helps with constipation, and some types can actually make it worse. The two kinds that reliably work are coarse insoluble fiber (like wheat bran) and gel-forming soluble fiber (like psyllium husk). Coarse insoluble fiber stimulates your gut lining to secrete water and mucus, while gel-forming soluble fiber holds onto water and resists being dried out as it moves through the colon. Both result in softer, bulkier stools that are easier to pass.
Fermentable fibers like inulin and fructooligosaccharides, which are common in many “high fiber” processed foods and supplements, don’t provide the same laxative benefit. Some, like wheat dextrin, can even be constipating. So if you’ve been adding fiber and not seeing results, the type matters as much as the amount.
The recommended daily fiber intake is about 14 grams per 1,000 calories you eat, which works out to roughly 25 grams for most women and 38 grams for most men. Over 90 percent of women and 97 percent of men fall short of this target. Good sources include whole wheat bran, oats, beans, lentils, pears, and psyllium-based supplements. Increase your intake gradually over a week or two to avoid bloating.
Drink Enough Water
When your body is low on fluids, your colon compensates by pulling extra water out of your stool to maintain hydration elsewhere. The result is dry, hard stool that’s difficult to pass. A large study analyzing data from over 10,000 U.S. adults found a clear relationship: higher fluid intake correlated with lower constipation risk. This is especially important if you’re increasing your fiber intake, since fiber needs water to do its job. Bulk-forming fiber supplements taken without enough water can actually cause bloating or even a blockage.
There’s no single magic number for how much to drink, but aiming for six to eight glasses of water throughout the day is a reasonable baseline. If your urine is pale yellow, you’re generally well-hydrated.
Move Your Body
Physical activity helps stool move through your colon faster. A study measuring the relationship between exercise intensity and gut transit time found that even high-light intensity activity (think brisk walking, light cycling, or active housework) was associated with significantly faster colonic transit, independent of age, sex, or body weight. You don’t need to run a marathon. A 20 to 30 minute walk, especially after a meal, can be enough to get things moving.
Sedentary behavior has the opposite effect. If you sit at a desk most of the day, even short movement breaks throughout the day can help.
Over-the-Counter Laxatives
If lifestyle changes aren’t enough, several types of laxatives are available without a prescription. They work differently, so choosing the right one depends on your situation.
- Bulk-forming laxatives (like psyllium) work the same way dietary fiber does, retaining fluid in the stool to make it softer and heavier. They’re the gentlest option and suitable for regular use, but you need to drink plenty of water with them.
- Osmotic laxatives (like polyethylene glycol or milk of magnesia) draw water into the bowel from surrounding tissue, softening the stool. These are a good next step when fiber alone isn’t working.
- Stimulant laxatives (like bisacodyl or senna) directly trigger contractions in the intestinal wall and reduce water absorption. They’re the most forceful option and work the fastest, but they’re best reserved for occasional use rather than daily reliance.
What Your Stool Tells You
The Bristol Stool Scale is a simple way to gauge whether your digestive system is on track. It classifies stool into seven types:
- Types 1 and 2: Hard lumps or a lumpy sausage shape. These indicate constipation, meaning stool has been sitting in the colon too long and lost too much water.
- Types 3 and 4: A sausage with surface cracks or a smooth, soft snake shape. These are the ideal range, suggesting a healthy transit time.
- Types 5, 6, and 7: Soft blobs, mushy pieces, or entirely liquid. These mean stool is moving through too quickly for enough water to be absorbed.
If you’re consistently seeing Type 1 or 2 despite trying the strategies above, or if constipation has persisted for six months or more, that’s worth bringing up with a doctor. The same goes for any sudden, unexplained changes in your bowel habits, blood in your stool, or significant unexplained weight loss. These are considered red flags that warrant further evaluation to rule out an underlying cause.
