If you’re sitting on the toilet waiting for something to happen, there are several things you can do right now to get things moving. Some work within minutes, others within hours, and a few changes can prevent the problem from recurring. Here’s what actually works, starting with the fastest options.
Change Your Position on the Toilet
The angle of your body on the toilet matters more than most people realize. When you sit on a standard toilet, a muscle called the puborectalis wraps around your rectum like a sling, pulling it forward and creating a kink. That kink is useful most of the day because it helps you stay continent. But when you’re trying to go, it works against you.
Squatting widens this angle significantly, creating a straighter path for stool to pass through. You don’t need to squat on the floor. Place a small stool or step (about 7 to 9 inches tall) under your feet while sitting on the toilet, lean forward slightly, and let your knees rise above your hips. This mimics a squatting position and relaxes the muscle enough to make a noticeable difference, especially if you feel like stool is right there but won’t come out.
Use the Gastrocolic Reflex to Your Advantage
Your colon has a built-in reflex that kicks in when your stomach stretches after eating or drinking. This is called the gastrocolic reflex, and it triggers increased contractions in the colon that push stool toward the exit. You can start feeling movement within minutes of eating, though for some people it takes up to an hour. The reflex can stay active for anywhere from a few minutes to a few hours.
To use this strategically, eat a meal (particularly breakfast, when the reflex tends to be strongest after a night of fasting) and then head to the bathroom about 15 to 30 minutes later. A warm drink can amplify the effect. Coffee is especially effective here: both caffeinated and decaf coffee stimulate the release of a hormone called gastrin, which increases stomach contractions, relaxes key valves in the digestive tract, and boosts colon motility. So coffee works through two pathways at once, the gastrocolic reflex triggered by the liquid hitting your stomach and the hormonal boost from gastrin.
Try an Abdominal Massage
Massaging your abdomen in the right direction can physically help move stool through the colon. The technique follows the path of your large intestine, which runs up the right side of your abdomen, across the top, and down the left side. A method called the ILU massage (named for the letter shapes your hands trace) takes about 5 to 15 minutes and can be done while sitting or lying down.
Start with the “I” stroke: place your hand just under your left rib cage and slide it straight down toward your left hip bone with gentle pressure. Repeat 10 times. Next, the “L” stroke: start below your right rib cage, move across the upper abdomen to the left rib cage, then down to the left hip. Repeat 10 times. Finally, the “U” stroke: start at your right hip, move up to your right rib cage, across to the left rib cage, and down to the left hip. Repeat 10 times. Finish with small clockwise circles around your belly button, about 2 to 3 inches out, for 1 to 2 minutes.
Over-the-Counter Laxatives
If positioning, food, and massage aren’t enough, laxatives are the next step. The two main categories work differently and on different timelines.
Osmotic laxatives pull water into the colon, softening stool so it’s easier to pass. The salt-based versions (like magnesium hydroxide, sold as milk of magnesia) act the fastest, working in as little as 30 minutes to 6 hours. Other osmotic types can take one to three days.
Stimulant laxatives (like bisacodyl or senna) activate the nerves controlling the muscles in your colon, essentially forcing it into motion. These typically take 6 to 12 hours, so taking one before bed often produces a morning result.
For the quickest relief when you need it now, a saline osmotic laxative or a glycerin suppository (which works locally in the rectum) will act fastest. Stimulant laxatives are better suited for overnight relief. Neither type should become a daily habit without guidance, since your colon can start to depend on stimulant laxatives over time.
Increase Fiber and Water Intake
If constipation is a recurring problem, your daily fiber intake is the single most important thing to evaluate. The recommended amount is about 14 grams per 1,000 calories you eat, which works out to roughly 25 grams for most women and 34 grams for most men. Most people fall well short of this. Fiber is considered a nutrient of public health concern in the U.S. specifically because so few people get enough of it.
Fiber works by absorbing water and adding bulk to stool, which gives the colon something to grip and push forward. This means increasing fiber without also increasing water can actually make things worse. Aim for at least 8 cups of fluid a day, and more if you’re adding fiber supplements. When increasing fiber, do it gradually over a week or two. A sudden jump can cause bloating and gas while your gut adjusts.
Good sources include beans, lentils, oats, berries, pears, broccoli, and ground flaxseed. If food sources aren’t practical, a psyllium husk supplement is an effective alternative.
Move Your Body
Physical activity stimulates the muscles of the colon in a similar way to the gastrocolic reflex. Even a 10 to 15 minute walk can be enough to get things moving, particularly after a meal. More vigorous exercise like jogging or yoga (especially poses that involve twisting the torso) tends to be more effective. If you’ve been sedentary for a few days due to illness, travel, or a desk-heavy schedule, that alone may explain the slowdown.
When the Problem Might Be Muscular
If you frequently feel the urge to go but can’t seem to push stool out, or if you strain hard with little result, the issue may not be diet or hydration at all. A condition called dyssynergic defecation affects the coordination of your pelvic floor muscles during a bowel movement. In most cases, the muscles that should relax when you bear down fail to let go. In some people, those muscles actually tighten instead, working directly against the effort to push. About half of people with this condition also have a reduced ability to feel stool in the rectum or to sense the urge to go.
This is worth considering if you’ve tried the standard fixes (fiber, water, movement, positioning) and nothing consistently helps. Pelvic floor physical therapy, which involves retraining these muscles to coordinate properly, is the primary treatment and has a high success rate. A gastroenterologist can diagnose it with specific tests that measure how your muscles respond during a simulated bowel movement.
Signs You Need Immediate Help
Most constipation is uncomfortable but not dangerous. However, a complete intestinal obstruction is a medical emergency that often requires surgery. If you have severe abdominal pain that comes in waves, vomiting (especially if it looks or smells like stool), a completely distended abdomen, and an inability to pass any gas at all, go to the emergency room. The combination of no stool and no gas is the key distinguishing feature. Regular constipation still allows gas to pass; a full obstruction does not.
