If you’re constipated, the fastest relief usually comes from a combination of immediate physical strategies and, if needed, an over-the-counter laxative. Most people are considered constipated when they have fewer than three bowel movements per week, or when more than a quarter of their bowel movements involve straining, hard lumpy stools, or a feeling of incomplete emptying. The good news: most cases resolve within a few days with simple interventions you can start right now.
Start With Your Position on the Toilet
Before reaching for any product, change how you sit. Your body was designed to eliminate in a squatting position, which straightens the angle between your rectum and colon. When you sit on a standard toilet with your feet flat on the floor, that passage stays kinked. Placing a footstool (6 to 9 inches tall) under your feet while you sit recreates a squatting posture, relaxing the pelvic floor muscles so the rectum opens into a funnel shape rather than a tight bend.
Lean forward slightly, rest your elbows on your knees, and let your belly relax outward. Breathe slowly and avoid holding your breath or straining hard. Give yourself a few unhurried minutes. This simple repositioning can make a noticeable difference, especially if you tend to strain.
Try Abdominal Self-Massage
A gentle clockwise massage over your abdomen can help move stool along the large intestine. Start at your lower right side near the hip bone. Press firmly with one or both hands and slide upward toward your rib cage, then across to the left side, then down toward your lower left hip. You’re tracing the path of your colon. Think of it like squeezing toothpaste through a tube. Continue for about two minutes, take a short break, then repeat for another two minutes. This technique is used in several hospital physiotherapy programs and works best when done before a meal or before sitting on the toilet.
Eat More Fiber, but Do It Gradually
Fiber adds bulk and water to stool, making it softer and easier to pass. Current dietary guidelines recommend about 14 grams of fiber for every 1,000 calories you eat daily, which works out to roughly 25 to 30 grams for most adults. Many people get far less than that.
Good sources include beans, lentils, oats, whole wheat bread, berries, broccoli, and pears. If your diet has been low in fiber, increase it slowly over a week or two. Adding too much at once can cause bloating and gas, which may make you feel worse before you feel better.
Prunes deserve a special mention. A randomized trial published in the American Journal of Gastroenterology found that eating about 100 grams of dried plums per day (roughly 12 prunes) significantly increased the number of complete bowel movements per week compared to baseline. Prunes performed just as well as psyllium fiber supplements, and they contain sorbitol, a natural sugar alcohol that draws water into the intestine. If you don’t like prunes, psyllium husk powder mixed into water or a smoothie is an effective alternative.
Over-the-Counter Laxatives That Work
If dietary changes and physical techniques aren’t enough, several types of laxatives are available without a prescription. They work differently, so choosing the right one depends on how quickly you need relief.
Osmotic Laxatives
These draw water into the intestine to soften stool. Polyethylene glycol 3350 (sold as MiraLAX and store brands) is one of the most commonly recommended options. It’s a tasteless powder you dissolve in any beverage. Relief typically takes one to three days, so this isn’t the choice for immediate results, but it’s gentle, well-tolerated, and safe for short-term daily use.
Magnesium Citrate
This liquid osmotic laxative works faster, generally producing a bowel movement within 30 minutes to 6 hours. The adult dose is 6.5 to 10 fluid ounces. It’s effective for more stubborn episodes but can cause cramping and loose stools, so stay near a bathroom after taking it. Don’t use it regularly without medical guidance, especially if you have kidney problems.
Stimulant Laxatives
Senna and bisacodyl (sold as Dulcolax and similar brands) stimulate the muscles of the intestinal wall to contract and push stool forward. Senna generally produces a bowel movement in 6 to 12 hours, which is why many people take it at bedtime for morning relief. Stimulant laxatives are best reserved for occasional use rather than a daily habit, since your bowel can become dependent on them over time.
Does Drinking More Water Help?
You’ll hear this advice everywhere, but the evidence is more nuanced than “just drink more water.” A review of clinical studies on fluid intake and constipation found no clear proof that increasing water consumption alone reliably resolves constipation in people who are already adequately hydrated. Where extra fluids do help is when you’re also increasing fiber. Fiber absorbs water, and if you don’t drink enough while eating a high-fiber diet, the added bulk can actually make constipation worse. A reasonable goal is 6 to 8 glasses of fluid per day, and warm beverages like coffee or tea in the morning can stimulate the colon’s natural contractions.
Daily Habits That Prevent Recurrence
Once you’ve resolved the immediate problem, a few routine changes can keep constipation from coming back. Physical activity is one of the most reliable. Walking, jogging, or any movement that engages your core helps stimulate the rhythmic contractions that push stool through the colon. Even a 20-minute walk after a meal can make a difference.
Respond to the urge when it comes. Many people suppress the need to go because they’re busy or away from home, and over time this trains the rectum to stop signaling as strongly. Try sitting on the toilet at the same time each day, ideally 15 to 30 minutes after a meal, when your body’s natural gastrocolic reflex is most active. This reflex is the wave of contractions your colon produces in response to eating, and it’s strongest after breakfast.
Review your medications. Opioid painkillers are a well-known cause, but antihistamines, certain blood pressure medications, iron supplements, and antacids containing calcium or aluminum can all slow things down. If you suspect a medication is contributing, talk to your prescriber about alternatives or adding a preventive laxative.
Signs That Need Medical Attention
Most constipation is uncomfortable but not dangerous. Certain symptoms, however, warrant a prompt call to your doctor: blood in your stool or on the toilet paper, unintended weight loss of 10 pounds or more, constipation that starts suddenly in someone over 50 with no history of it, stools that become persistently thinner than usual, or iron deficiency anemia found on blood work. A family history of colon cancer also lowers the threshold for further evaluation. These red flags don’t necessarily mean something serious is wrong, but they signal that your doctor should rule out structural or systemic causes rather than treating symptoms alone.
