If you can’t poop, the fastest things you can try right now are drinking a large glass of warm water, putting your feet up on a stool while sitting on the toilet, and eating a few prunes. For more stubborn situations, an over-the-counter laxative can get things moving within hours. Constipation is incredibly common, and most episodes resolve with simple changes you can make at home.
Clinically, constipation means fewer than three bowel movements per week, but you don’t need to hit that threshold to feel miserable. Straining through more than a quarter of your bathroom visits, consistently passing hard lumpy stools, or feeling like you never fully empty out all count. Here’s what to do about it, starting with what works fastest.
Fix Your Position on the Toilet
The way you sit on a standard toilet actually works against you. A U-shaped muscle called the puborectalis wraps around your rectum like a sling, creating a kink that holds stool in place. When you sit at a 90-degree angle, that kink stays partially locked. X-ray studies confirm that the rectum straightens out significantly more in a squatting position, giving stool a clearer path out.
You don’t need to squat on the rim of your toilet. Place a footstool, a stack of books, or an overturned box under your feet so your knees rise above your hips. Lean forward slightly with your elbows on your thighs. This mimics a squat and relaxes that muscle enough to make a real difference, especially if you’ve been straining.
Try an Abdominal Massage
You can physically help move stool through your colon with a simple self-massage. The technique follows the path of your large intestine in a clockwise direction. Start at your lower right side near your hip bone. Using firm, deep pressure with one or both hands, slide upward toward your right rib cage, then across your upper abdomen to the left, then down the left side toward your lower left hip. Think of it like squeezing toothpaste through a tube. Continue for about two minutes, and repeat if needed.
Eat Prunes or High-Fiber Foods
Prunes are one of the most effective natural remedies for constipation, and it’s not just the fiber. They contain sorbitol, a sugar alcohol that draws water into the intestines. Prunes pack about 14.7 grams of sorbitol per 100 grams, and as little as 5 grams of sorbitol can produce a laxative effect. A serving or two of prunes (roughly 4 to 6) is usually enough to get things moving. Don’t overdo it: 20 grams or more of sorbitol can cause severe cramping and diarrhea.
Beyond prunes, increasing your overall fiber intake helps prevent the problem from recurring. Most adults fall short of their daily fiber goals. Women need 22 to 28 grams per day depending on age, while men need 28 to 34 grams. A useful rule of thumb is 14 grams per 1,000 calories. Good sources include beans, lentils, pears, raspberries, oats, and flaxseed. If you’re adding fiber to your diet, ramp up gradually over a week or two and drink extra water. A sudden jump in fiber without enough fluid can actually make constipation worse.
Drink More Water, Especially Warm
Dehydration is one of the simplest and most overlooked causes of hard stool. Your colon absorbs water from the food passing through it, and when your body is short on fluids, it pulls out more than usual, leaving behind dry, difficult-to-pass stool. Drinking a large glass of warm water first thing in the morning can stimulate your gastrocolic reflex, the natural wave of muscle contractions your colon makes in response to your stomach filling up. Coffee has a similar effect for many people, though it can also be mildly dehydrating, so pair it with water.
Over-the-Counter Laxatives
When home remedies aren’t cutting it, laxatives are the next step. There are two main categories worth knowing about, and they work differently.
Osmotic Laxatives
These pull water from other parts of your body into your colon, softening the stool so it’s easier to pass. The most widely used option is polyethylene glycol (sold as MiraLAX). You mix a dose into a glass of water and drink it. The standard versions take one to three days to work, though saline-based types like magnesium hydroxide (Milk of Magnesia) act faster, typically within 30 minutes to six hours. These are generally considered gentle enough for regular use under a doctor’s guidance.
Stimulant Laxatives
These activate the nerves that control your colon muscles, essentially forcing your intestines to contract and push stool along. Bisacodyl and senna are the most common options. They typically work within 6 to 12 hours, so many people take them at bedtime and have a bowel movement by morning. Stimulant laxatives are effective for occasional use but aren’t meant for daily long-term use.
If you need faster relief, a glycerin suppository works locally in the rectum and can produce results within 15 to 60 minutes.
Magnesium for Faster Relief
Magnesium citrate, available as a liquid at most pharmacies, is a stronger osmotic laxative that works relatively quickly. It draws a significant amount of water into the intestines and typically produces a bowel movement within a few hours. The standard adult dose is 195 to 300 mL taken with a full glass of water. This is more of a one-time rescue option than a daily supplement. It’s effective but can cause cramping, and it’s not appropriate for people with kidney problems since the kidneys handle magnesium clearance.
Movement and Timing
Physical activity stimulates the muscles in your intestinal wall. Even a 10 to 15 minute walk can help. You don’t need intense exercise; gentle movement like walking, stretching, or yoga twists that compress the abdomen are often enough to nudge a sluggish colon.
Timing matters too. Your colon is most active in the morning and after meals, thanks to that gastrocolic reflex. Try sitting on the toilet for 5 to 10 minutes after breakfast, even if you don’t feel an urge yet. Consistency trains your body to expect a bowel movement at that time. Don’t strain or push hard, as this can lead to hemorrhoids over time. If nothing happens after 10 minutes, get up and try again later.
What’s Making You Constipated
Fixing the immediate problem is one thing, but it helps to understand what caused it. The most common culprits are not drinking enough water, eating too little fiber, being sedentary, and ignoring the urge to go (which trains your rectum to stop sending the signal as strongly). Travel, changes in routine, and stress also slow things down because your gut and nervous system are tightly connected.
Several common medications cause constipation as a side effect. Pain medications (especially opioids), iron supplements, certain blood pressure drugs, and some antidepressants are frequent offenders. If constipation started around the same time you began a new medication, that’s likely the connection. Don’t stop the medication on your own, but it’s worth a conversation about alternatives or adding a daily osmotic laxative to your routine.
Signs That Need Medical Attention
Most constipation resolves within a few days with the strategies above. If it lasts longer than a week, it’s worth getting checked. You should seek urgent care if you haven’t had a bowel movement for a prolonged period and you’re also experiencing severe abdominal pain or major bloating, as this could indicate a bowel obstruction. Blood in your stool, vomiting alongside constipation, or unexplained weight loss are also warning signs that point to something beyond ordinary constipation.
