Several things can help you poop, ranging from simple dietary changes to over-the-counter products that work within hours. Most people need about 14 grams of fiber per 1,000 calories they eat each day, and falling short of that target is one of the most common reasons for sluggish bowels. The good news is that a combination of food, fluids, movement, and (if needed) a mild laxative can usually get things moving again.
Fiber: The Most Reliable Long-Term Fix
Fiber is the single most effective daily habit for keeping bowel movements regular. It works two ways: insoluble fiber adds physical bulk to stool, while soluble fiber draws water into the stool, making it softer and easier to pass. The larger, softer mass triggers your colon to contract and push things along naturally.
Current dietary guidelines recommend 14 grams of fiber for every 1,000 calories you eat. For most adults, that lands somewhere between 25 and 35 grams a day. The easiest sources are beans, lentils, oats, berries, broccoli, pears, and whole-grain bread. If your current intake is low, increase it gradually over a week or two. Adding too much fiber at once can cause bloating and gas, which defeats the purpose.
A fiber supplement (the bulk-forming type you mix into water) is a reasonable option if you can’t hit your target through food alone. These work the same way dietary fiber does, pulling water into stool and increasing its size. They’re generally safe for daily use, but you need to drink plenty of water with them or they can make constipation worse.
Prunes Actually Work
Prunes have a reputation for a reason. They contain about 15 grams of sorbitol per 100 grams, a naturally occurring sugar alcohol that draws water into the intestines and has a well-documented laxative effect. But sorbitol isn’t the whole story. Prunes also deliver 184 milligrams of antioxidant polyphenols per 100 grams, plus a mix of soluble and insoluble fiber. Researchers at Tufts University have noted that it’s likely this combination of compounds, not just fiber alone, that makes prunes more effective than other high-fiber foods for constipation.
A serving of five or six prunes (about 50 grams) is a reasonable starting point. You can also try prune juice, though it contains less fiber than whole prunes. Kiwifruit is another option with similar evidence behind it, as it contains an enzyme that helps break down protein in the gut and speeds transit.
Water and Coffee
Staying hydrated matters more than most people realize. A study of 100 adults with chronic constipation found a significant association between water intake and how often people had bowel movements. Dehydration makes stool harder and more difficult to pass because your colon absorbs extra water from waste when your body is running low. Drinking enough fluid, roughly 8 cups a day for most people, keeps stool soft.
Coffee is a different kind of tool. It triggers your stomach lining to release a hormone called gastrin, which stimulates the muscles in your colon to contract. If your colon is already loaded, this can produce a bowel movement within minutes of your first few sips. Decaf coffee has a milder version of this effect, which means it’s not just the caffeine at work. Coffee won’t fix chronic constipation, but it can be a reliable morning trigger.
Physical Movement
Exercise stimulates the natural contractions of your intestines. Even a 10 to 15 minute walk can help, especially after a meal when your digestive system is already active. The combination of gravity, core muscle engagement, and increased blood flow to the gut makes walking one of the simplest ways to encourage a bowel movement. Yoga poses that involve twisting the torso can also help by gently compressing the intestines.
If you’ve been sedentary for a few days (traveling, recovering from illness, desk-bound), that alone may explain why things have slowed down.
Positioning on the Toilet
Your body is designed to eliminate more easily in a squat than in a sitting position. When you sit on a standard toilet, a muscle called the puborectalis creates a kink in your rectum that partially blocks the exit. Elevating your feet on a small stool (about 7 to 9 inches high) straightens that angle and allows stool to pass with less straining. Leaning forward slightly with your elbows on your knees amplifies the effect. This is a free, immediate change that helps many people.
Over-the-Counter Laxatives
When diet and lifestyle changes aren’t enough, there are three main types of laxatives available without a prescription, and they work in different ways.
- Osmotic laxatives pull water from other parts of your body into your colon, softening stool so it’s easier to pass. Magnesium citrate is one common option. It typically produces a bowel movement within 30 minutes to 6 hours. It should not be used for more than one week without medical guidance.
- Stimulant laxatives activate the nerves controlling your colon muscles, forcing the colon into motion. These are stronger and faster-acting but can cause cramping. They’re best reserved for occasional use rather than a daily habit.
- Bulk-forming laxatives are the gentlest option. They add soluble fiber to your stool, drawing in water and making it bigger and softer. The increased size triggers your colon to contract naturally. These are the closest to how dietary fiber works and are safe for regular use.
Stool softeners are another category worth knowing about. They don’t stimulate the colon at all. Instead, they add moisture to stool, which helps if your main problem is hard, dry stool that’s painful to pass.
Probiotics for Regularity
Certain probiotic strains can improve bowel frequency, though the effect is modest compared to fiber or laxatives. In a controlled trial published in the American Journal of Gastroenterology, adults who had fewer than three bowel movements per week took a specific strain of Bifidobacterium for 28 days. Compared to placebo, the probiotic group had significantly more bowel movements and less straining. The higher dose was more effective than the lower dose.
Probiotics work best as one piece of a broader approach rather than a standalone fix. You can get them through fermented foods like yogurt, kefir, kimchi, and sauerkraut, or through supplements. Results typically take a few weeks to show up, so they’re not useful if you need relief today.
When Constipation Signals Something Else
Occasional constipation is extremely common and usually harmless. But certain patterns warrant a conversation with your doctor: blood in your stool, unintentional weight loss, persistent abdominal pain, or constipation that starts suddenly in your 50s or later with no obvious cause. A family history of colon cancer also lowers the threshold for getting checked. If your constipation started shortly after beginning a new medication (common culprits include certain pain relievers, antidepressants, and blood pressure drugs), the medication itself may be the cause, and your doctor can often suggest an alternative.
