What Can I Drink To Make Me Poop Top Options?

If you are backed up and looking for something to drink that helps you poop, the most evidence-backed options are water, prune juice, coffee, and kefir. These drinks work through different mechanisms — some add fluid, some stimulate the gut, and others feed your gut bacteria. Below is a breakdown of what the research actually says about each one, how they compare, and what to watch out for.

Does Drinking More Water Help With Constipation?

Yes, but only if you are actually dehydrated. The idea that everyone needs eight glasses of water a day to stay regular is not backed by strong evidence for people who already drink enough fluids.

Research published in the European Journal of Clinical Nutrition found that increasing water intake only improved constipation in people who were not drinking enough in the first place. For someone who is already hydrated, adding more water does not make stool softer or speed up transit time.

The real issue is that many people mistake thirst for hunger or just do not drink enough throughout the day. If your urine is dark yellow, you are likely dehydrated and drinking more water will help. If it is pale or clear, extra water is not going to fix constipation.

Start your day with a glass of water. It is simple and there is no downside. Just do not expect it to work if you are already well-hydrated.

Does Coffee Really Make You Poop?

For many people, yes. Coffee stimulates the colon within minutes of drinking it. This is not just about caffeine. Decaf coffee has a similar effect, though usually weaker.

A study in the Journal of Gastroenterology found that coffee triggers contractions in the colon about as strongly as a meal does. This is called the gastrocolic reflex — the same signal that tells your body to poop after eating. Coffee seems to amplify that signal.

The effect is not universal. Some people feel nothing from coffee. Others feel a strong urge within five to ten minutes. If you are one of the people who responds, a morning cup of hot coffee can be a reliable way to get things moving.

One note: coffee is a diuretic, so it makes you pee more. But for most people, the fluid in the coffee still counts toward your total water intake. The mild fluid loss from urination does not cancel out the hydration benefit.

What Can I Drink To Make Me Poop Top Options: Prune Juice

Prune juice is the most studied drink for constipation. It works better than most over-the-counter fiber supplements for mild to moderate constipation.

Research in Alimentary Pharmacology & Therapeutics compared prune juice to psyllium fiber. The people who drank prune juice had more bowel movements per week and reported less straining. Prunes contain sorbitol, a sugar alcohol that pulls water into the colon, plus a compound called dihydroxyphenylisatin that stimulates contractions.

The dose matters. One small glass — about half a cup or 120 milliliters — is usually enough. Drinking more than that in a short time can cause cramping, gas, and diarrhea. Start with a smaller amount and see how your body responds.

Prune juice has a strong taste that some people do not like. If that is the case, whole prunes work just as well. The fiber in whole prunes may even be slightly more effective because it is not removed during juicing.

Can Fermented Drinks Like Kefir Help?

Some evidence suggests yes, but the effect is modest and takes time. Kefir is a fermented milk drink loaded with probiotics — live bacteria that can influence your gut microbiome.

A review in Nutrients looked at multiple studies on probiotics for constipation. Strains of Bifidobacterium and Lactobacillus — both found in kefir — were linked to faster gut transit time and softer stools. But the improvement was not dramatic. People who drank kefir daily for two to four weeks had about one extra bowel movement per week on average.

Kefir is not a quick fix. It does not work in minutes like coffee or prune juice. But for people with chronic constipation, adding a daily serving of kefir may help over the long term.

One catch: store-bought kefir varies wildly in probiotic content. Some brands pasteurize after fermentation, which kills the live bacteria. Look for brands that say “live and active cultures” on the label. Better yet, make your own if you have the patience.

What About Herbal Teas and Lemon Water?

Herbal teas marketed for constipation — like senna, cascara, or buckthorn — contain plant compounds called anthraquinones that stimulate the colon. They work, but they carry risks.

Senna tea is the most common. It is approved by the FDA as a laxative. But long-term use can cause the colon to become dependent on stimulation. Over time, your bowel may stop moving on its own. This is called laxative dependency, and it is a real problem for people who use these teas daily for months or years.

Lemon water, on the other hand, has no direct evidence behind it for constipation. Some people report that warm lemon water in the morning helps them go, but that is likely the warmth and hydration, not the lemon itself. Lemon contains citric acid, which can stimulate digestion slightly, but there is no solid research backing it as a treatment for constipation.

If you want to try herbal teas, stick to ones without senna or cascara for daily use. Peppermint or ginger tea may help with bloating and gas, but they will not make you poop on their own.

Comparison of Drinks for Constipation

What to Avoid Drinking When Constipated

Some drinks make constipation worse. Alcohol is one of them. It dehydrates the body, and dehydration pulls water out of the stool, making it harder and harder to pass. If you are already backed up, alcohol will not help.

Sugary sodas and sweetened fruit juices are another problem. High sugar content, especially from high-fructose corn syrup, can slow gut transit time in some people. The sugar also feeds certain gut bacteria that produce gas, which adds to bloating and discomfort without helping the stool move.

Dairy can be tricky. For people who are lactose intolerant, milk can cause gas and bloating but sometimes also diarrhea. For people who tolerate dairy fine, milk does not typically cause constipation. But if you notice that cheese or milk makes you feel more stopped up, try cutting it out for a week to see if things improve.

One more drink to be careful with: energy drinks. Most contain caffeine, which can stimulate the colon, but they also contain taurine and other compounds that may dehydrate you. The net effect is unpredictable. Stick with plain coffee if you want the stimulant effect without the extra additives.

Common Misconceptions About Drinks and Pooping

A big one is that apple juice works the same as prune juice. It does not. Apple juice contains some sorbitol, but much less than prune juice. You would need to drink three to four times as much apple juice to get the same laxative effect, and that comes with a lot of extra sugar.

Another myth is that warm water is better than cold water. There is no evidence that water temperature affects digestion or bowel movements. Warm water may feel soothing, but it does not make you poop faster than cold water. The temperature difference is irrelevant to your colon.

Some people believe that drinking more milk will cure constipation because milk has calcium. In reality, high calcium intake from supplements can actually cause constipation. Food sources of calcium, like milk, do not typically cause this problem, but they do not fix it either.

Finally, there is the idea that any drink with fiber added — like certain smoothies or fiber powders mixed into water — will instantly relieve constipation. Fiber needs water to work. If you add fiber without increasing your water intake, you can actually make constipation worse. Fiber bulks up stool, and if there is not enough fluid, that bulk just gets stuck.
