If you’re constipated and want relief, the fastest options are changing your position on the toilet, drinking more fluids, and moving your body. For more stubborn cases, over-the-counter laxatives can produce a bowel movement within hours to a few days depending on the type. Most episodes of constipation resolve with simple adjustments and don’t signal anything serious.
Constipation generally means fewer than three bowel movements per week, hard or lumpy stools, excessive straining, or a feeling that you haven’t fully emptied. You don’t need all of these to be constipated. Any combination that’s bothering you counts.
Fix Your Position on the Toilet
The angle of your body on the toilet has a surprisingly large effect on how easily stool passes. When you sit on a standard toilet, the muscle that wraps around your rectum keeps a kink in the passage at roughly 80 to 90 degrees. That kink acts like a bent garden hose, making you strain harder to push stool through.
When you raise your knees above your hips (mimicking a squat), that angle opens to about 100 to 110 degrees, straightening the passage and requiring less effort. The simplest way to do this is to place a footstool, a stack of books, or an upside-down shoebox under your feet while sitting on the toilet. Lean slightly forward with your elbows on your knees. Many people notice an immediate difference the first time they try this.
Drink More Fluids
Dehydration makes stool harder because your colon absorbs extra water from waste when your body is running low. Research from a large national health survey found a clear dose-response relationship between total fluid intake and constipation risk: the more fluid people consumed, the lower their odds of being constipated. There’s no magic number of glasses that guarantees relief, but if you suspect you’re not drinking enough, increasing your water intake throughout the day is one of the easiest first steps. Coffee and warm liquids can also stimulate the colon, which is why many people find a morning cup of coffee gets things moving.
Get Moving
Physical activity speeds up the time it takes waste to travel through your colon. A study measuring the relationship between activity levels and gut transit found that each additional hour of brisk light-intensity activity (think a fast walk) was associated with roughly 25% faster colonic transit time, independent of age, sex, or body fat. You don’t need an intense gym session. A 20- to 30-minute walk, especially after a meal, can be enough to stimulate your digestive system and help trigger a bowel movement.
Eat More Fiber (the Right Kind)
Fiber is the single most important long-term dietary factor for staying regular, and most people fall well short of recommended intake: 25 grams per day for women and 38 grams for men. There are two types, and both matter.
Insoluble fiber, found in whole wheat, vegetables, and the skins of fruits, adds bulk to stool and reduces the time it takes to move through your intestines. Soluble fiber, found in oats, beans, apples, and flaxseed, absorbs water and forms a gel that softens stool and makes it easier to pass. If you’re constipated right now, foods high in soluble fiber tend to offer faster relief. Prunes are a particularly effective choice because they contain both fiber and a natural sugar alcohol that draws water into the colon.
One important note: if your diet is currently low in fiber, increase gradually over a week or two. Adding too much at once can cause bloating and gas, which makes the discomfort worse before it gets better.
Try Abdominal Massage
Massaging your abdomen in the direction your colon flows can help move stool along. Start on your lower right side near your hip bone, press gently with your fingertips, and move upward toward your ribs. Then go across your upper abdomen from right to left, and down the left side toward your left hip. You’re essentially tracing a large upside-down U shape, following the path of the colon. Use firm but comfortable pressure and repeat for five to ten minutes. One clinical comparison found that patients using regular abdominal massage achieved ideal bowel movement frequency 75% of the time, compared to 25% for those using a stimulant laxative alone.
Over-the-Counter Laxatives
When lifestyle changes aren’t enough, laxatives can help. The two main categories work differently and have different timelines.
Osmotic Laxatives
These work by pulling water into the colon to soften stool. The most widely recommended option (sold as MiraLAX and generic versions) is mixed as a powder into 8 ounces of liquid and taken once daily. It’s gentle and well-tolerated, but it’s not instant. Expect your first bowel movement in two to four days. This type is a good choice for moderate constipation when you can afford to wait a couple of days.
Stimulant Laxatives
These directly trigger the muscles of your colon to contract, pushing stool forward while also increasing the water content of stool. Oral tablets typically work within 6 to 12 hours, so taking one before bed often produces a morning bowel movement. Suppository forms work much faster, usually within 15 to 60 minutes. Stimulant laxatives are more appropriate when you need quicker relief, but they can cause cramping and shouldn’t be used daily for long periods.
What About Probiotics?
Probiotic supplements are heavily marketed for digestive health, but the evidence for constipation relief is underwhelming. A rigorous clinical trial testing one of the most-studied strains for constipation found that participants taking the probiotic gained less than one additional bowel movement per week compared to those taking a placebo, and the difference was not statistically significant. Fermented foods like yogurt and kefir are fine to include in your diet, but don’t count on a probiotic supplement as your primary strategy for getting unconstipated.
When Constipation Is a Red Flag
Most constipation is uncomfortable but harmless. However, certain combinations of symptoms warrant prompt medical attention. If you haven’t had a bowel movement in an extended period and you’re also experiencing severe abdominal pain or significant bloating, that could indicate a bowel obstruction. Vomiting alongside constipation, blood in your stool, or unexplained weight loss are also warning signs that need evaluation. These situations are uncommon, but they require a trip to the emergency room rather than home remedies.
