Constipation Relief: 15 Evidence-Based Strategies That Work

Constipation is no fun. The bloating and abdominal discomfort that often come with it can be uncomfortable and sometimes even painful. It is also something many people feel awkward talking about, even though most of us have experienced it at some point. In fact, constipation affects an estimated 8 to 12 percent of adults, making it far more common than people realize.

Constipation rarely happens out of the blue. What you eat, how much you drink, how you move your body, your sleep, stress levels, medications, and daily routines all play a role in how well your digestive system functions. When one or more of these factors is off, bowel movements can slow down.

In this post, we will break down what constipation is, common causes, and 15 evidence based diet and lifestyle strategies to help relieve it.

What is Constipation?

Constipation is often described as not going to the bathroom often enough, but in practice it is a little more nuanced than that. Constipation occurs when stool moves too slowly through the digestive tract or becomes hard and difficult to pass.

In my work with clients, I often see people who say, “I go every day, so I can’t be constipated.” Yet they describe straining, hard stools, or the feeling that they are never quite finished. Others may only go every few days but feel comfortable when they do. This is why frequency alone does not tell the full story.

You may be experiencing constipation if you notice:

• Fewer than three bowel movements per week
• Hard, dry, or painful stools
• Straining during bowel movements
• A persistent feeling of incomplete evacuation

Because constipation can look different from person to person, healthcare providers often rely on stool consistency, not just frequency, to assess what is going on.

One of the simplest ways to do this is by using a visual tool called the Bristol Stool Chart.

 

The Bristol Stool Chart

Some people find a visual helpful when trying to understand what is normal and what may signal constipation. The Bristol Stool Chart is a clinically used tool that categorizes stool into seven types based on shape and consistency, ranging from very hard to completely liquid.

• Types 1 and 2 are small, hard, and difficult to pass. These are classic signs of constipation.
• Type 3 may still suggest mild constipation, particularly if stools are dry or require straining.
• Type 4 is considered ideal. Stools are smooth, soft, and easy to pass.
• Types 5 through 7 move toward loose stools and diarrhea.

While many people focus on how often they have a bowel movement, stool consistency often provides more useful information. Someone may go daily but still be constipated if stools are hard or uncomfortable to pass. Others may go less frequently but feel complete and comfortable when they do.

Using stool form rather than frequency alone can give a clearer picture of how well your digestive system is functioning and whether constipation may be an issue.

 

Common Causes of Constipation

Constipation rarely has a single cause. For most people, it develops when several factors come together and slow how stool moves through the digestive tract. This is why addressing constipation often requires looking beyond just fiber or laxatives.

Diet plays a major role. A low intake of fiber, especially from plant foods, can reduce stool bulk and slow transit time. Inadequate fluid intake can compound the problem, making stools dry and harder to pass.

Travel is a good example of how quickly these factors can stack up. When people travel, they often eat differently, drink less water, sit for long periods, sleep poorly, and ignore the urge to go because bathrooms feel inconvenient or unfamiliar. Even a short trip can disrupt normal bowel patterns.

Lifestyle factors matter as well. Regular movement helps stimulate the muscles of the colon, while a sedentary routine can slow motility. Poor sleep and ongoing stress can interfere with digestive rhythms through the gut–brain connection, which we’ll explore in more detail later.

Certain medications and supplements are also common contributors. Iron, calcium, some antidepressants, and pain medications can slow bowel movements. Medical conditions such as irritable bowel syndrome, inflammatory bowel disease, and some neurological disorders may further affect bowel function.

Habits play an important role as well. Repeatedly ignoring the urge to have a bowel movement can dull the body’s natural signals over time, increasing the risk of chronic constipation.

For many people, constipation improves most when these contributors are addressed together rather than focusing on a single change.

 

The Gut–Brain Connection

When people think about constipation, stress is rarely the first thing that comes to mind. Yet the gut and brain are in constant communication through a network of nerves, hormones, and chemical messengers often referred to as the gut–brain axis. This connection plays a major role in digestion, including how quickly stool moves through the colon.

When stress levels are high, the nervous system shifts into a “fight or flight” state. In this mode, digestion is not a priority. Gut motility can slow, abdominal muscles may tense, and bowel movements can become more difficult or irregular. This is one reason constipation often shows up during stressful periods, busy workweeks, or times of disrupted routines.

On the flip side, a calmer nervous system supports digestion. Gentle movement, deep breathing, and consistent routines help activate the parasympathetic nervous system, sometimes referred to as “rest and digest.” This can improve coordination of the muscles involved in bowel movements and make stools easier to pass.

There is also a biochemical component. About 90 to 95 percent of the body’s serotonin is produced in the gut, where it helps regulate intestinal movement. Changes in gut health, stress levels, or sleep can affect serotonin signaling and contribute to constipation.

This is why addressing constipation often requires more than just dietary changes. Supporting the gut–brain connection through lifestyle habits is an important part of improving regularity.

 

15 Evidence-Based Diet and Lifestyle Strategies to Relieve Constipation

1. Increase Your Fiber Intake

Fiber is often the first thing people think of when it comes to constipation relief, and for good reason. Fiber helps add bulk to stool, draws water into the colon, and supports healthy gut motility. That said, how you increase fiber matters just as much as how much you get.

There are two main types of fiber and both play a role in regular bowel movements.

Soluble fiber absorbs water and helps soften stool, while insoluble fiber adds bulk and helps stool move through the digestive tract more efficiently. Most people benefit from a mix of both rather than focusing on just one type.

In practice, I often see constipation improve when people increase fiber from whole foods rather than relying on a single “high-fiber” product. Fruits, vegetables, beans, lentils, whole grains, nuts, and seeds all contribute different types of fiber that support gut function in complementary ways.

Variety matters. Aim for a wide range of plant foods across the week to nourish the gut microbiome and support stool consistency.

It is also important to increase fiber gradually. A sudden increase can lead to bloating and discomfort, especially if fluid intake does not increase at the same time. For some people, more is not better. Adding large amounts of fiber when you are already constipated can make symptoms worse. It is often helpful to first resolve the constipation, then slowly add more fiber based on how your digestion responds. Adequate fluid intake is essential throughout this process.

 

2. Stay Hydrated

Hydration plays a critical role in constipation relief, especially when fiber intake increases. Water helps soften stool and supports movement through the colon. Without adequate fluids, stool can become dry and difficult to pass, even if fiber intake is adequate.

Many people underestimate how much fluid they actually need. While needs vary based on body size, activity level, and climate, aiming for at least 65 ounces of fluid per day is a reasonable starting point for many adults. Water is best, but fluids from herbal tea, seltzer, and water-rich foods also contribute.

Hydration becomes even more important during travel, hot weather, illness, or periods of increased physical activity, all of which can increase fluid losses and worsen constipation. Spreading fluid intake throughout the day tends to be more effective than drinking large amounts all at once.

If plain water is hard to get down, adding a squeeze of citrus, drinking sparkling water, or pairing fluids with meals can make hydration more manageable.

 

3. Don’t Skip Breakfast

Morning is often the best time of day to support a bowel movement. The gut–brain connection tends to be more active after waking, and eating breakfast helps trigger the gastrocolic reflex, a natural response that encourages the colon to contract after meals.

Skipping breakfast can mean missing this window altogether. For some people, that can contribute to slower bowel movements later in the day or more irregular patterns overall.

A balanced breakfast that includes fiber, protein, and fluids can be especially helpful. Examples include chia seed pudding, oatmeal with nuts and fruit, or eggs with vegetables and whole-grain toast. Coffee may also stimulate bowel movements for some people, though its effects can vary.

Even a small breakfast can be beneficial. The goal is not perfection, but consistency, giving your digestive system a reliable signal to get things moving.

 

4. Establish Regular Meal Times

Your digestive system thrives on routine. Eating at consistent times helps regulate the body’s internal clock and supports predictable movement of food through the digestive tract, including the colon.

When meals are skipped or eaten at irregular times, the signals that stimulate gut motility can become less reliable. Over time, this can contribute to sluggish digestion and constipation. Regular meals help activate what is known as the gastrocolic reflex, a natural response that encourages bowel movements after eating.

For many people, simply spacing meals more evenly throughout the day can make a noticeable difference. This does not mean eating on a rigid schedule, but rather avoiding long stretches without food and creating a general rhythm that the digestive system can anticipate.

Pairing regular meal times with other supportive habits, such as hydration and gentle movement, can further reinforce regular bowel patterns.

 

5. Incorporate Specific Constipation-Fighting Foods

Certain foods have been shown to be particularly helpful for relieving constipation because they support stool softness, hydration, and gut motility. Including these foods regularly can make a meaningful difference for many people.

• Green kiwi: Aim for two per day. Kiwi contains a unique combination of fiber, water, and bioactive compounds that support digestion. I’ve seen this play out in practice as well. One client who struggled with chronic constipation added two green kiwis per day to her routine without making any other major changes. Within a couple of weeks, she noticed her stools were softer, bowel movements were more regular, and she felt less bloated. For her, it was a simple, sustainable change that made a meaningful difference.
  Pro tip: In smoothies, keep the skin on for extra fiber.
• Mangoes, prunes, apricots, and peaches: These fruits contain natural sugars and sugar alcohols that have an osmotic effect, drawing water into the colon to help soften stools.
• Chia seeds: These small but powerful seeds are rich in soluble fiber, which absorbs water and helps form softer, easier-to-pass stools. Add them to oatmeal or smoothies, or make chia seed pudding as a simple option.

Rather than focusing on just one food, most people see the best results when these options are included as part of a consistent, balanced approach alongside adequate fluids, movement, and routine.

6. Prioritize Quality Sleep

Sleep and digestion are more closely connected than many people realize. Poor or inconsistent sleep can disrupt hormonal signaling and digestive rhythms, making bowel movements less regular over time.

When sleep is shortened or fragmented, stress hormones tend to rise. This can affect the gut–brain connection and slow motility in the colon. People who consistently get too little sleep often notice more bloating, irregularity, or difficulty passing stool.

Aim for 7 to 9 hours of quality sleep per night whenever possible. Consistent bedtimes, limiting late-night screens, and creating a calming wind-down routine can all support both sleep quality and digestive health.

Improving sleep does not have to be perfect to be helpful. Even small changes, such as going to bed a bit earlier or creating more consistency during the week, can positively impact gut function.

 

7. Engage in Regular Exercise

Movement helps keep the digestive system moving. Physical activity stimulates the muscles of the gastrointestinal tract, including the colon, which can support more regular bowel movements.

You do not need intense workouts for this benefit. Moderate activity, such as walking, swimming, cycling, or light strength training, can be effective. Even short bouts of movement throughout the day can help stimulate gut motility, especially for people who spend long hours sitting.

Many people find that a 10 to 15 minute walk after meals is particularly helpful. Activities that incorporate deep breathing, such as yoga or Pilates, may offer added benefits by supporting both movement and the gut–brain connection.

The key is consistency rather than intensity. Regular movement, even at a gentle level, tends to be more beneficial for constipation relief than sporadic, high-intensity exercise.

It’s also worth noting that very intense or prolonged exercise can sometimes worsen constipation for some people, particularly if it increases stress hormones, disrupts routines, or leads to inadequate fueling or hydration.

 

8. Manage Stress

Stress is a sneaky one. Many of my clients notice that their digestive symptoms get worse during stressful periods, whether that shows up as constipation, diarrhea, bloating, or all of the above.

This happens because stress shifts the nervous system into a “fight or flight” mode. When the body is focused on managing stress, digestion takes a back seat. Gut motility can slow, abdominal muscles may tense, and bowel movements can become more difficult or irregular.

The goal is not to eliminate stress entirely, which is unrealistic. Instead, supporting the nervous system with small, consistent habits can make a real difference. Deep breathing, gentle movement, short walks, mindfulness, or even slowing down before meals can help signal to the body that it is safe to digest.

For many people, addressing stress alongside nutrition and lifestyle changes is a key part of improving bowel regularity.

9. Be Aware of Your Menstrual Cycle

Hormonal changes throughout the menstrual cycle can affect digestion, but those changes do not look the same for everyone. Some people notice constipation in the one to two weeks leading up to their period, while others experience looser stools or diarrhea, particularly right before or during menstruation. Some may even alternate between the two.

These shifts are largely driven by hormones. Higher progesterone levels in the second half of the cycle can relax the muscles of the digestive tract, slowing gut motility and contributing to constipation. Around the time of menstruation, prostaglandins increase and can stimulate intestinal contractions, which may lead to more frequent bowel movements or diarrhea.

Stress, changes in appetite, sleep disruption, and fluid shifts during the cycle can further influence digestion. Because these patterns tend to repeat month to month, tracking your cycle can be helpful. Noticing when symptoms show up allows you to be more proactive with hydration, fiber tolerance, movement, and stress management during those phases.

While these changes are common, severe or disruptive symptoms are not something you have to simply live with. If bowel changes around your period are persistent or significantly affect your quality of life, it’s worth discussing with a healthcare provider.

 

10. Use Proper Toilet Posture

How you sit on the toilet can influence how easily stool passes. Modern toilets place the body in a seated position that is not ideal for bowel movements, which can make elimination more difficult for some people.

Raising your feet on a small stool or footrest helps mimic a squatting position. This changes the angle of the rectum and can reduce strain while allowing stool to pass more naturally. Many people notice that bowel movements feel easier and more complete with this simple adjustment.

Personally, I’m a fan of the Squatty Potty, but any stable stool or footrest that elevates your feet can work just as well. The goal is comfort and ease, not forcing anything. This strategy is especially helpful for people who strain, feel incomplete evacuation, or have difficulty relaxing during bowel movements.

 

11. Establish a Regular Bathroom Routine

Your body responds well to routine, and that includes bowel movements. Setting aside consistent time each day to use the bathroom can help retrain your body’s natural signals and support more regular bowel habits. For many people, the best time is in the morning, especially after breakfast, when the gastrocolic reflex is naturally active. Allowing yourself a few unhurried minutes can make a meaningful difference. Feeling rushed, distracted, or tense can make it harder for the body to relax enough for a bowel movement.

I often hear from clients that constipation is worse when they are away from home, such as at work or in public restrooms. When possible, setting yourself up for success at home can help. Getting up a bit earlier, eating a good-sized breakfast, staying hydrated, and having coffee if that is part of your routine can encourage a bowel movement in a familiar, relaxed environment.

If you do need to go outside the home, try to recreate that same sense of calm. Take a few slow breaths, avoid rushing, and use proper toilet posture if possible. Reminding yourself that bowel movements are a normal bodily function and that everyone has them can also help reduce tension.

This routine is about creating opportunity, not forcing results. Sitting on the toilet at the same time each day helps your body learn when it is time to go, even if nothing happens right away at first. Over time, this consistency can improve both the frequency and ease of bowel movements.

 

12. Don’t Force It

When it comes to bowel movements, more effort does not equal better results. Straining or sitting on the toilet for long periods trying to make something happen can actually make constipation worse and increase the risk of issues like hemorrhoids or pelvic floor dysfunction. If nothing happens after about five minutes, it’s usually best to get up and go about your day. Your body will often signal again when it is ready. This approach reinforces the idea that bowel movements should happen with relative ease, not force.

For many people, learning to let go of urgency and pressure is an important part of improving regularity. Creating the opportunity to go, then trusting your body to respond in its own time, tends to work better than pushing or straining.

Over time, this mindset shift can help bowel movements feel more natural and less stressful.

 

13. Supplements for Constipation

While diet and lifestyle changes are the foundation of constipation relief, some people benefit from supplements when those strategies are not enough. Supplements work best when used selectively and intentionally, rather than as a first step or a quick fix.

Fiber supplements are not all the same.

• Psyllium (such as Metamucil) is the most studied fiber supplement for constipation. It absorbs water and forms a gel-like texture that can help soften stool and improve regularity. It should be started slowly and always paired with adequate fluids.
• Methylcellulose (such as Citrucel) is a non-fermentable fiber and tends to cause less gas and bloating, which may make it a better option for people who do not tolerate psyllium well.
• Wheat dextrin (such as Benefiber) is generally well tolerated, though evidence for constipation relief is less robust.

Magnesium supplements can also be helpful for some people. Forms such as magnesium citrate or magnesium oxide draw water into the stool and may stimulate bowel movements. Dosing matters, as higher amounts can lead to diarrhea or cramping.

Probiotics may help some individuals, but research is mixed and benefits are strain-specific. Effects, when they occur, are usually modest. For those interested in probiotic supplements, the U.S. Probiotic Guide is a useful evidence-based resource for understanding which strains have been studied for specific digestive concerns.

If constipation persists or worsens despite careful use of supplements, it is important to reassess rather than continuing to add more.

 

14. Consider Probiotic-Rich Foods

Probiotic-rich foods such as yogurt, kefir, and fermented vegetables may help support gut health for some people, but the research on constipation is mixed. Some individuals notice improvements in stool consistency or frequency, while others notice little change.

Start with small portions and pay attention to how your digestion responds. These foods tend to work best as part of a broader approach that includes adequate fiber, fluids, movement, and routine.

If probiotic foods increase bloating or discomfort, they may not be a good fit, and that is okay. They are optional, not essential, for constipation relief.

15. Medications

Certain medications can contribute to constipation, including opioid pain medications, some antidepressants, iron supplements, calcium supplements, certain blood pressure medications, and newer medications such as GLP-1 receptor agonists. If constipation begins or worsens after starting a medication, it’s worth discussing with your doctor

In other cases, medications are used to help manage constipation when diet and lifestyle strategies aren’t enough. Examples include:

• Polyethylene glycol (PEG)— such as MiraLAX, a commonly used osmotic laxative.
• Magnesium salts— including magnesium citrate or magnesium hydroxide (Milk of Magnesia).
• Stimulant laxatives— such as senna and bisacodyl (Dulcolax)
• Stool softeners— like docusate (Colace).
• Prescription options that may be considered when OTC treatments aren’t effective include lubiprostone, linaclotide, or plecanatide for chronic constipationOf course, all medications should be discussed with your healthcare provider so they can be tailored to you and used safely.

When to Seek Help for Constipation

Occasional constipation is common and often improves with diet and lifestyle changes. However, ongoing or worsening symptoms deserve medical attention.

You should speak with a healthcare provider if:

• Constipation lasts more than three weeks despite making changes
• You experience significant abdominal pain
• You notice blood in your stool
• You have unintentional weight loss
• Constipation alternates with persistent diarrhea
• Symptoms are severe enough to affect daily life

Chronic constipation can sometimes signal an underlying medical condition or require a more targeted treatment approach. Seeking care can help ensure that nothing important is being overlooked and that treatment is appropriate for your situation.

Bottom Line

Constipation can be uncomfortable and disruptive, but the good news is that diet and lifestyle changes can make a meaningful difference.
