Plenty of everyday foods, drinks, and habits can get your bowels moving. Whether you’re dealing with occasional constipation or just want more regularity, the options range from dietary changes that work within hours to lifestyle shifts that keep things consistent over days and weeks.
Fiber: The Most Reliable Option
Fiber increases the weight and size of your stool and softens it, making it easier to pass. It works in two ways. Insoluble fiber, found in whole wheat, nuts, and vegetables, doesn’t dissolve in water. It adds bulk to stool and physically pushes material through your digestive system. Soluble fiber, found in oats, beans, apples, and citrus fruits, dissolves in water and forms a gel-like material that keeps stool from getting too hard or too loose.
Fiber works best when it absorbs water, so increasing your fiber intake without drinking enough fluids can actually make things worse. The federal dietary guidelines recommend about 14 grams of fiber per 1,000 calories you eat, which works out to roughly 25 grams a day for most women and 38 grams for most men. Most Americans fall well short of that. Adding fiber gradually, rather than all at once, helps you avoid the bloating and gas that come with a sudden increase.
Foods That Act as Natural Laxatives
Some foods go beyond fiber alone. Prunes are the classic example, and for good reason: they contain both soluble and insoluble fiber plus sorbitol, a sugar alcohol your body absorbs slowly. Sorbitol pulls water into the intestine, softening stool and speeding things along. Just a handful of prunes (about five or six) is enough for many people to notice an effect within a few hours.
Pears also contain sorbitol along with fructose, which has a similar water-pulling effect. Kiwifruit, figs, and flaxseed are other well-studied options. The key pattern is the same: a combination of fiber and natural compounds that draw water into the gut, keeping stool soft enough to move.
Coffee and the Morning Reflex
Coffee makes many people need the bathroom, and it’s not just the caffeine. Compounds in coffee trigger the release of gastrin, a hormone produced in the stomach lining that stimulates movement throughout the entire digestive tract. This effect happens with both regular and decaf coffee, though caffeine adds an extra push.
Timing matters too. Your intestines are naturally most active in the morning due to something called the gastrocolic reflex, a wave of contractions triggered when you put anything in your stomach after a night of fasting. Coffee amplifies that reflex. Drinking a cup of warm coffee (or even warm water) first thing in the morning is one of the fastest non-medication ways to trigger a bowel movement.
Water and Hydration
Your colon’s main job is absorbing water from digested food as it forms stool. When you’re not drinking enough, the colon pulls out more water than usual, leaving stool hard and dry. This is one of the most common and most overlooked causes of constipation. There’s no magic number of glasses per day that works for everyone, but if your urine is consistently dark yellow, you’re likely not drinking enough to keep stool soft. Warm liquids in particular seem to stimulate gut movement more than cold ones.
Physical Activity
Moving your body moves your bowels. Research tracking adults with accelerometers found that physical activity at a brisk walking pace was associated with colonic transit times about 25% faster than in sedentary individuals, independent of age, sex, or body fat. Interestingly, the benefit came specifically from moderate activity like brisk walking or light cycling. Sitting all day and then doing an intense gym session didn’t show the same association. The takeaway is that regular, consistent movement throughout the day matters more than occasional hard workouts.
Even a 15 to 20 minute walk after a meal can be enough to get things moving, especially if you’re someone who spends most of the day seated.
Abdominal Massage
Massaging your abdomen in a specific pattern can physically help stool move through the colon. A large review of studies found that abdominal massage increased bowel movements by about 1.5 extra per week and cut gut transit time by roughly 21 hours compared to doing nothing. The basic technique follows the path of your colon: start on your lower right side near your hip, move up toward your ribs, across to the left, and then down the left side. Use firm but comfortable pressure in slow, circular motions. Five to ten minutes once or twice a day is the range most studied.
Probiotics
Certain probiotic strains can speed up a sluggish gut. A meta-analysis of 14 trials found that specific probiotics decreased gut transit time by about 12 hours and increased stool frequency by roughly 1.5 bowel movements per week in adults with functional constipation. The effect was strain-specific: Bifidobacterium lactis strains consistently improved transit time, stool frequency, and consistency, while some other popular strains showed no benefit at all. If you’re trying probiotics for regularity, look for products that list specific strains (not just species) and expect to give them two to four weeks before judging the results.
Over-the-Counter Laxatives
When food and lifestyle changes aren’t enough, several categories of laxatives are available without a prescription. They differ mainly in how fast they work and how they do it.
- Bulk-forming laxatives (psyllium, methylcellulose) work like concentrated fiber supplements. They absorb water and expand in your gut. Expect results in 12 hours to three days.
- Osmotic laxatives (polyethylene glycol, magnesium hydroxide) pull water into the intestine to soften stool. Most take one to three days, though liquid magnesium products can work in as little as 30 minutes.
- Stool softeners (docusate) make stool easier to pass by mixing in moisture. They take 12 hours to three days and are the gentlest option.
- Stimulant laxatives (bisacodyl, senna) directly trigger the muscles of the intestinal wall to contract. They work in 6 to 12 hours and are best reserved for occasional use rather than daily reliance.
Magnesium supplements, particularly citrate and oxide forms, are also widely used for constipation. They work by drawing water into the intestine, similar to osmotic laxatives. Starting with a low dose and increasing gradually helps you find the amount that works without causing cramping or diarrhea.
Putting It Together
For a quick fix right now, your fastest options are warm coffee in the morning, a magnesium-based osmotic laxative, or a stimulant laxative. For day-to-day regularity, the combination of adequate fiber (from food first, supplements if needed), enough water, and consistent physical activity addresses the three most common reasons stool slows down: not enough bulk, not enough moisture, and not enough intestinal movement. Adding prunes or other sorbitol-rich fruits gives you an extra edge without any supplements at all.
