When you’re constipated and need relief now, the fastest option is a glycerin or stimulant suppository, which typically produces a bowel movement within 15 minutes to an hour. But there are also several things you can do right this moment, without a trip to the pharmacy, that help move things along. Here’s what actually works, ranked roughly by how fast it can help.
Change Your Position on the Toilet
The simplest thing you can do right now costs nothing. 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 sharp angle that partially blocks the exit. This is useful most of the time (it keeps you continent), but it works against you when you’re trying to go.
Squatting widens that angle, creating a straighter path from your colon to the anal canal. People who squat during bowel movements also report less abdominal straining. You don’t need to hover over the toilet. Place a small footstool, a stack of books, or even a shoebox under your feet so your knees rise above your hips. Lean forward slightly with your elbows on your thighs. This mimics a squatting position and can make a noticeable difference, especially if you’ve been sitting upright and pushing hard.
Try Abdominal Massage
Massaging your abdomen in a specific pattern can physically help push stool through your large intestine. Think of it like squeezing toothpaste through a tube. Using one or both hands with firm, deep pressure, start at your lower right groin area and slide upward toward your ribcage. Then move across your abdomen from right to left, and finally press downward along your left side toward your lower left groin. This follows the natural path of your colon.
Continue this clockwise motion for about two minutes. You can repeat it several times. Combining this massage with the squatting position on the toilet is a reasonable first attempt before reaching for any product.
Drink Coffee or Warm Liquids
Coffee stimulates your gut in ways that go beyond just adding fluid. Compounds in coffee trigger the release of a hormone called gastrin from your stomach lining, and gastrin directly increases the muscular contractions that push contents through your digestive tract. The effect varies widely from person to person, and some people feel the urge within minutes. If coffee doesn’t do it for you, warm water or warm tea can also activate similar reflexes, though less powerfully. Drinking a warm liquid while gently massaging your abdomen is worth trying before moving to stronger options.
Glycerin and Stimulant Suppositories
If physical techniques aren’t enough, a rectal suppository is the fastest over-the-counter product available. Glycerin suppositories work by drawing water into the rectum and lubricating the stool, typically producing a bowel movement in 15 minutes to one hour. Stimulant suppositories containing bisacodyl work within 20 to 60 minutes by triggering contractions in the rectal muscles.
For comparison, the oral tablet version of bisacodyl takes 10 to 12 hours to work. That’s because it has to travel through your entire digestive system first. If speed is what you need, the rectal route bypasses that wait entirely. Suppositories are available at virtually any pharmacy without a prescription.
Saline Enemas
A pre-packaged saline enema (the small squeeze-bottle type sold at drugstores) works on a similar timeline to suppositories, generally within 15 minutes to an hour. The saline solution draws water into the lower bowel, softening stool and stimulating the urge to go. These are straightforward to use at home and are a reasonable step when a suppository hasn’t worked or when stool feels very hard and close to the exit but won’t pass.
Magnesium Citrate for Same-Day Relief
If you don’t need results in the next 15 minutes but want relief today, magnesium citrate is a liquid you can buy over the counter that works within 30 minutes to 6 hours. It pulls water into your intestines, which softens stool and increases the volume in your colon enough to trigger contractions. It’s taken as a single dose. The taste is easier to handle when it’s chilled. Be prepared to stay near a bathroom once it kicks in, because the effect can be strong and somewhat urgent.
When Constipation May Be Something More Serious
Most constipation episodes are uncomfortable but harmless. However, a condition called fecal impaction happens when stool becomes so hard and packed that it physically cannot pass, and it requires medical help. The tricky part is that impaction can disguise itself: one of its hallmark signs is watery diarrhea that leaks around the hardened mass, which you might mistake for the opposite problem. Other warning signs include nausea, abdominal bloating that feels like intense pressure, dehydration, confusion, or rectal bleeding.
If you’ve tried multiple approaches over several days with no results, or if you’re experiencing any of those severe symptoms, this is beyond what home remedies can fix. A healthcare provider can check for impaction and clear it safely.
