Best Constipation Treatments: 13 Effective Options

Best Constipation Treatments depend on what is causing the problem. For many adults, the best first steps are gradual fiber, enough fluid, regular movement, a bowel routine, and better toilet positioning. If medicine is needed, polyethylene glycol has some of the strongest evidence for ongoing adult constipation.

But constipation is not one problem with one cure.

Someone with dry, hard stool needs a different plan from someone who feels blocked even when the stool is soft. A child who withholds stool also needs a different approach from an older adult taking several medicines.

The goal is simple: match the treatment to the pattern.

NIDDK advises prompt medical assessment when constipation occurs with vomiting, constant abdominal pain, inability to pass gas, fever, bleeding, or unexplained weight loss.

Those symptoms can point to something more serious than ordinary constipation, including fecal impaction or a bowel obstruction.

What Is Constipation?

Constipation means more than simply missing a day.

NIDDK lists common symptoms such as:

• Fewer than three bowel movements in a week
• Hard stool that is dry or lumpy
• Pain or difficulty passing stool
• Feeling that stool remains after you finish

You can therefore have constipation even if you pass a small amount of stool each day.

The feeling of incomplete evacuation matters.

So does the stool itself.

If it is hard and dry, the treatment may focus on fiber, fluid, and an osmotic laxative. If the stool is already soft but still feels trapped, adding more fiber may not solve the problem.

Which Constipation Pattern Do You Have?

This distinction is one reason there is no single best laxative for every person.

13 Best Constipation Treatments and When Each Makes Sense

1. Increase Dietary Fiber Gradually

Dietary fiber is a sensible first step for many people with ordinary constipation.

NIDDK says adults generally need about 22 to 34 grams of fiber each day, depending on age and sex.

Useful foods include:

• Oats
• Whole grain bread
• Pears
• Apples with skin
• Berries
• Prunes
• Beans
• Lentils
• Peas
• Vegetables
• Nuts
• Seeds

Do not jump from a very low fiber diet to a very high fiber diet overnight.

That can produce gas, bloating, and abdominal discomfort.

Increase fiber in stages.

For a food based guide, see High Fiber Foods Chart for Constipation.

2. Consider Psyllium When Food Fiber Is Not Enough

Psyllium is a soluble fiber supplement that absorbs water and forms a gel.

The joint AGA and ACG constipation guideline suggests fiber supplementation for adults with chronic idiopathic constipation, with the strongest practical evidence among studied fibers favoring psyllium.

Start gradually.

Take it with enough fluid unless a healthcare professional has told you to restrict fluids.

Fiber is not the right answer for every pattern.

If you are vomiting, severely swollen, or unable to pass gas, do not simply add more bulk.

3. Drink Enough Fluid for Your Own Needs

There is no universal “eight glasses” rule that fits everyone.

Your fluid needs depend on:

• Your size
• Activity
• Climate
• Diet
• Pregnancy
• Illness
• Kidney function
• Heart health
• Medicines

NIDDK recommends enough water and other liquids, especially when increasing fiber.

More water does not automatically cure constipation if you are already well hydrated.

If you have been told to limit fluid because of kidney disease, heart failure, or another condition, follow your medical plan.

4. Move Your Body Regularly

Regular physical activity can support normal bowel movement.

You do not need an intense workout.

Options include:

• Walking
• Cycling
• Swimming
• Yoga
• Gentle strength work
• Regular daily movement

If you have been sitting for long periods, even a short walk is a reasonable start.

For more ideas, read Constipation Exercises.

5. Use a Regular Bowel Routine

The colon often becomes more active after eating.

This is known as the gastrocolic reflex.

NIDDK suggests bowel training as one possible treatment strategy.

A practical routine is to:

1. Eat breakfast.
2. Wait about 15 to 45 minutes.
3. Sit on the toilet without rushing.
4. Relax rather than straining hard.
5. Go when you feel the urge rather than repeatedly delaying it.

Consistency is more useful than spending a long time pushing.

6. Improve Your Toilet Position

A small footstool can help some people pass stool more comfortably.

Place your feet on the stool so your knees sit slightly higher than your hips.

Lean forward gently and relax your belly.

A better position cannot correct every type of constipation, but it is easy to try and carries little downside for most people.

If you feel physically blocked despite soft stool, the issue may be muscular rather than dietary.

7. Consider Polyethylene Glycol for Adult Chronic Constipation

Polyethylene glycol, often called PEG or macrogol, is an osmotic laxative.

It pulls water into the bowel, helping make stool easier to pass.

This treatment has some of the strongest evidence among over the counter options.

The joint AGA and ACG guideline gives PEG a strong recommendation for adults with chronic idiopathic constipation.

The 2026 American Family Physician summary of colorectal surgery guidelines also recommends osmotic laxatives such as PEG ahead of stimulant laxatives when medication is needed.

PEG is not designed to work like an immediate rescue suppository.

It is more useful as a planned treatment for the right type of constipation.

8. Use Stimulant Laxatives for the Right Situation

Stimulant laxatives increase bowel activity.

Common examples include:

• Bisacodyl
• Senna
• Sodium picosulfate in countries where it is available

The AGA and ACG guideline strongly recommends bisacodyl or sodium picosulfate for short term use or rescue treatment in adults with chronic idiopathic constipation.

Senna receives a conditional recommendation.

Stimulants can work faster than PEG, but “fastest” does not mean “best for daily long term use.”

ACG patient guidance notes that oral stimulant laxatives commonly act within several hours, while some suppositories act faster.

Follow the product instructions and get professional advice if you need stimulant treatment repeatedly.

9. Consider Other Osmotic Laxatives When Appropriate

Other osmotic laxatives include:

• Magnesium based products
• Lactulose

They work by keeping more water in the bowel.

The joint AGA and ACG guideline conditionally supports magnesium oxide and lactulose in selected adults with chronic idiopathic constipation.

Magnesium products deserve extra caution in people with kidney disease because magnesium can build up in the body.

Lactulose can cause gas and bloating in some people.

This is one reason treatment should be chosen rather than randomly stacked.

10. Use Prescription Medicines When Over the Counter Care Is Not Enough

Persistent chronic constipation does not mean you should keep increasing several over the counter products forever.

Prescription options include:

• Linaclotide
• Plecanatide
• Lubiprostone
• Prucalopride

The 2023 AGA and ACG guideline strongly recommends linaclotide, plecanatide, and prucalopride for adults with chronic idiopathic constipation who have not responded adequately to over the counter treatment.

Lubiprostone is also suggested.

These medicines do not all work in the same way.

Linaclotide and plecanatide increase intestinal fluid. Prucalopride helps stimulate colon movement.

Your clinician can choose based on symptoms, other health conditions, side effects, previous treatment, and availability.

11. Treat Pelvic Floor Dysfunction With Biofeedback

This is one of the most useful distinctions missing from many constipation guides.

Sometimes the colon moves stool normally, but the muscles around the rectum do not relax correctly when you try to go.

Possible clues include:

• Long periods of straining
• Feeling physically blocked
• Repeated incomplete evacuation
• Needing to change position many times
• Soft stool that remains difficult to pass

The 2026 American Family Physician guideline summary recommends pelvic floor physical therapy with electromyography biofeedback therapy for constipation caused by pelvic floor dysfunction.

In this situation, another fiber supplement may not address the main problem.

Specialized testing can include anorectal manometry and a balloon expulsion test.

12. Treat Fecal Impaction as a Different Problem

Fecal impaction occurs when a large hard mass of stool becomes stuck and cannot pass normally.

It is more common in frail older adults, people with limited mobility, people with neurologic disease, and people with long standing severe constipation.

Possible clues include:

• Long lasting constipation
• Abdominal swelling
• Pain or pressure
• Nausea
• Loss of appetite
• Leakage of watery stool around the hard mass

That watery leakage can be mistaken for diarrhea.

Impaction may need stronger oral treatment, rectal medicine, an enema, or removal by a trained healthcare professional.

Do not try to remove impacted stool manually yourself.

13. Review Medicines and Look for the Underlying Cause

Sometimes the best constipation treatment is changing what caused it.

NIDDK lists medicines and supplements that can contribute to constipation, including some:

• Opioid pain medicines
• Antidepressants
• Anticholinergic medicines
• Calcium channel blockers
• Anticonvulsants
• Iron supplements
• Calcium or aluminum containing antacids
• Diuretics

Do not stop prescribed medicine on your own.

Ask your doctor or pharmacist whether the dose, timing, medicine choice, or constipation prevention plan can be improved.

Medical causes can also include:

• Hypothyroidism
• Diabetes
• Celiac disease
• Neurologic disorders
• IBS with constipation
• Pelvic floor disorders
• Colon or rectal disease

Which Constipation Medicine Has the Best Evidence?

For adults with chronic idiopathic constipation, PEG stands out among common over the counter medicines.

What About Stool Softeners Such as Docusate?

Docusate has been used for constipation for many years.

But the evidence is weaker than many people assume.

The AGA and ACG chronic idiopathic constipation guideline did not make a treatment recommendation for docusate because the evidence base was limited.

That does not mean nobody should ever use it.

It does mean that routinely calling it one of the “best” constipation treatments is hard to justify when better supported options exist.

What Is the Fastest Constipation Treatment?

The fastest option is not always the best option.

Stimulant suppositories can work relatively quickly. Oral stimulant laxatives can also act faster than many bulk or osmotic treatments.

But the choice depends on what is causing the constipation.

Do not use speed as the only goal when you have:

• Severe abdominal pain
• Vomiting
• A very swollen abdomen
• Inability to pass gas
• Possible impaction

Those symptoms need assessment before you simply add stronger laxatives.

Can Prunes and Kiwi Help?

Yes, food can be part of treatment.

Prunes provide fiber and sorbitol, which can help draw water into the bowel.

Kiwi contains fiber and has also been studied for constipation.

Useful everyday foods include:

• Prunes
• Kiwi
• Pears
• Oats
• Beans
• Lentils
• Vegetables
• Whole grains
• Ground flaxseed
• Chia seeds

Introduce high fiber foods gradually if your current intake is low.

For more options, visit the Gut Health Foods Guide.

Should You Use “Natural Laxatives”?

“Natural” is too broad to be a medical category.

Prunes and fiber rich foods are normal foods.

Senna, however, is a stimulant laxative even when it is sold as a herbal tea.

Aloe products can also cause diarrhea, cramps, and other unwanted effects.

Do not assume that a product is gentler or safer because the package uses words such as natural, cleanse, herbal, or detox.

Are Detox Teas a Good Constipation Treatment?

No.

Many detox teas simply contain stimulant laxatives such as senna.

They do not remove mysterious toxins from the colon.

Regular use can also make it harder to know what your bowel is doing without the product.

If you need repeated laxative treatment, use an evidence based plan rather than a detox product.

What Are the Best Constipation Treatments for Children?

Children need their own plan.

Do not simply give a young child an adult constipation product or adult dose.

NICE recommends that children with idiopathic constipation be assessed for fecal impaction first.

When medicine is needed, polyethylene glycol 3350 with electrolytes is recommended as first line treatment for childhood disimpaction and maintenance in the NICE guideline, with dose and product selection based on age and clinical guidance.

Treatment also includes:

• A regular toilet routine
• Positive encouragement
• No punishment for accidents
• Enough fluid
• A balanced diet
• Age appropriate fiber
• Normal physical activity

Diet alone should not be used as the only first line treatment when a child has established idiopathic constipation.

This is important.

A child who is withholding stool because it hurt last time can enter a cycle where withholding makes the stool larger and more painful.

Early treatment can break that cycle.

For more detail, read Kids Constipation Problem and Best Food for Kids Constipation.

When Should a Child With Constipation See a Doctor?

Get pediatric advice when constipation:

• Is persistent
• Causes significant pain
• Comes with vomiting
• Causes marked abdominal swelling
• Comes with blood that is more than a tiny streak from a known fissure
• Begins in very early infancy
• Occurs with poor growth
• Does not improve with an appropriate treatment plan

A pediatrician can also check for conditions such as celiac disease, thyroid problems, or Hirschsprung disease when the history suggests them.

What Are the Best Constipation Treatments During Pregnancy?

Constipation is common in pregnancy because hormones can slow the digestive tract.

Iron supplements can make it worse in some people.

ACOG recommends starting with practical measures such as:

• Eating more fiber rich foods
• Increasing fiber gradually
• Drinking enough water
• Staying physically active when pregnancy allows

ACOG suggests about 25 grams of fiber daily during pregnancy.

If those steps are not enough, ask your obstetric clinician or pharmacist which laxative is suitable for you.

Do not assume that every over the counter or herbal product is safe just because it does not need a prescription.

What About Constipation in Older Adults?

Constipation becomes more common with age, but it should not simply be dismissed as “normal aging.”

Older adults are more likely to have factors such as:

• Reduced mobility
• Several daily medicines
• Neurologic disease
• Lower food intake
• Dehydration risk
• Difficulty reaching a toilet
• Pelvic floor problems

Medication review is especially useful.

Opioids, iron, some antidepressants, anticholinergic medicines, and several other drugs can contribute.

Do not force large amounts of water into an older person who has a heart or kidney condition that requires fluid limits.

Frequent watery leakage in a person with long standing constipation can actually be overflow around an impaction.

What Is Opioid Induced Constipation?

Opioid medicines slow bowel movement.

Examples include morphine, oxycodone, hydrocodone, and codeine.

Constipation can continue for as long as the medicine is used.

If an opioid is necessary, ask the prescriber about constipation prevention early instead of waiting until stool becomes severely impacted.

Some people with persistent opioid related constipation need medicines designed specifically for that problem.

Can IBS Cause Constipation?

Yes.

IBS with constipation can cause:

• Abdominal pain
• Bloating
• Hard stool
• Straining
• Changing bowel frequency
• A feeling of incomplete emptying

The pain component matters.

Chronic constipation without significant abdominal pain and IBS with constipation are not exactly the same condition.

If your symptoms match IBS, read IBS Constipation Diet.

Can Constipation Cause Nausea?

Yes.

Constipation can occur with nausea, especially when bloating, pressure, or severe stool retention develops.

But nausea also raises the need to check the full pattern.

Vomiting plus severe pain, marked abdominal swelling, or inability to pass gas should not be treated as ordinary constipation.

See Can Constipation Cause Nausea? for a focused guide.

Can Constipation Cause Bloating?

Yes.

Stool remaining in the colon can make gas harder to move and create pressure or visible distention.

If bloating is a major part of your symptoms, see Bloating Gurgling Stomach.

When Is Constipation an Emergency?

Seek urgent assessment when constipation comes with:

• Severe or constant abdominal pain
• Repeated vomiting
• Inability to pass gas
• A very swollen or rigid abdomen
• Fainting
• Severe weakness
• Heavy rectal bleeding

A complete intestinal blockage is not something to treat at home with more fiber or more laxatives.

When Does Constipation Need a Doctor Even if It Is Not an Emergency?

Arrange medical assessment if:

• Constipation keeps returning
• Self care is not helping
• You regularly need laxatives
• Your bowel habit has changed without a clear reason
• You lose weight without trying
• You have anemia
• You see blood
• You have a family history of colorectal cancer
• You repeatedly feel blocked despite soft stool

The 2026 constipation guideline summary recommends looking for red flags such as bleeding, blood in stool, weight loss, anemia, altered stool caliber, and relevant family history.

How Do Doctors Find the Cause of Chronic Constipation?

A good evaluation starts with simple questions.

Your healthcare professional may ask:

• How often do you pass stool?
• Is it hard, soft, or lumpy?
• How long have symptoms lasted?
• Do you strain?
• Do you feel empty afterward?
• Do you have abdominal pain?
• Which medicines and supplements do you take?
• Have you lost weight?
• Is there blood?

NIDDK notes that testing can include blood work for anemia, hypothyroidism, and celiac disease when appropriate.

Other tests may include:

• Stool testing
• Colonoscopy in selected people
• Anorectal manometry
• Balloon expulsion testing
• Defecography
• Colon transit testing

Not everyone needs every test.

Should Everyone With Constipation Have a Colonoscopy?

No.

Constipation by itself does not automatically mean you need a colonoscopy.

Doctors consider your age, colorectal cancer screening status, family history, and warning signs such as bleeding, anemia, weight loss, or a concerning change in bowel habits.

A colonoscopy is used when there is a reason, not simply because stool is hard.

What Should You Avoid Doing?

• Do not increase fiber aggressively when you are vomiting or cannot pass gas.
• Do not take several laxatives together without knowing how they interact.
• Do not rely on detox teas.
• Do not manually remove impacted stool yourself.
• Do not ignore blood or unexplained weight loss.
• Do not give an adult laxative dose to a child.
• Do not assume pregnancy makes every herbal laxative safe.
• Do not keep adding fiber when soft stool still feels physically blocked.
• Do not stop prescribed medicines without speaking to the prescriber.

A Simple Constipation Plan for an Otherwise Well Adult

Step 1: Look for Warning Signs

If severe pain, vomiting, inability to pass gas, bleeding, or major swelling is present, get medical advice first.

Step 2: Check Your Fiber Pattern

If your diet is low in plant foods, increase fiber slowly.

Step 3: Drink Normally

Make sure you are not dehydrated, especially as fiber intake rises.

Step 4: Walk

Add normal movement to the day.

Step 5: Use the Toilet After Breakfast

Give the natural post meal bowel response a chance to work.

Step 6: Use a Footstool

Reduce unnecessary straining.

Step 7: Consider Evidence Based Medication

If simple steps are not enough, ask a pharmacist or clinician whether PEG or another suitable treatment fits your situation.

Step 8: Reassess

If treatment repeatedly fails, do not simply keep adding more laxatives. Look for medication effects, IBS, slow transit, pelvic floor dysfunction, or another cause.

Conclusion

The Best Constipation Treatments are not the strongest laxatives or the quickest products.

They are the treatments that match the cause.

Start with gradual fiber when appropriate, enough fluid, regular movement, bowel training, and a better toilet position. For adult chronic constipation that needs medication, polyethylene glycol has strong guideline support. Stimulant laxatives can be useful for short term or rescue treatment, while persistent cases may need prescription medicine or pelvic floor therapy.

Children, pregnancy, older adults, fecal impaction, and pelvic floor dysfunction all need a more specific approach.

Your next step is to look at your own pattern. If stool is hard, start with stool softening strategies. If stool is already soft but you still feel blocked, ask whether the pelvic floor is part of the problem. If severe pain, vomiting, bleeding, or inability to pass gas appears, stop treating it as routine constipation and get medical help.

About the Author

Frequently Asked Questions

What are the best constipation treatments?

The best treatment depends on the cause. For ordinary constipation, useful first steps include gradual fiber, enough fluid, regular movement, bowel training, and better toilet positioning. Polyethylene glycol has strong evidence when an adult needs ongoing medication for chronic idiopathic constipation.

What is the fastest way to relieve constipation?

Stimulant laxatives or suppositories can work faster than fiber or osmotic treatment, but faster is not always better. Severe pain, vomiting, abdominal swelling, or inability to pass gas needs medical assessment rather than simply taking a stronger laxative.

What is the best laxative for chronic constipation?

For adults with chronic idiopathic constipation, the AGA and ACG guideline gives polyethylene glycol a strong recommendation. Linaclotide, plecanatide, and prucalopride also have strong recommendations after over the counter treatment has not worked well enough.

Is polyethylene glycol safe for long term constipation?

PEG is one of the best supported over the counter medicines for adult chronic idiopathic constipation. Individual treatment still depends on your health, symptoms, and other medicines, so persistent constipation should be discussed with a healthcare professional.

Is senna safe for constipation?

Senna is a stimulant laxative and is conditionally recommended for adults with chronic idiopathic constipation. Follow dosing instructions and get medical advice if you need stimulant treatment repeatedly.

What foods help constipation naturally?

Useful foods include oats, pears, kiwi, prunes, berries, beans, lentils, vegetables, nuts, seeds, and whole grains. Increase fiber gradually and drink enough fluid for your needs.

Can too much fiber make constipation worse?

Yes. A sudden large increase can cause gas and bloating. Fiber also may not solve constipation caused by pelvic floor dysfunction, severe slow transit, or impaction.

Should I use a stool softener for constipation?

Stool softeners such as docusate are widely used, but the evidence supporting them is weaker than the evidence for polyethylene glycol. Ask a pharmacist or clinician which treatment best matches your symptoms.

What helps constipation in children?

Children need age appropriate treatment. NICE recommends assessment for impaction and uses polyethylene glycol based treatment as first line therapy for idiopathic childhood constipation when medicine is needed, alongside a regular toilet routine, adequate food and fluids, and positive behavioral support.

What helps constipation during pregnancy?

ACOG recommends increasing fiber gradually, drinking enough water, and staying active when possible. If those steps are not enough, ask your pregnancy care professional which laxative is suitable.

Why am I constipated even though I eat fiber?

Constipation can come from medicines, slow colon movement, IBS, pelvic floor dysfunction, thyroid disease, diabetes, neurologic disease, or another cause. Soft stool that still feels blocked is a clue that adding more fiber may not fix the problem.

What is pelvic floor constipation?

Pelvic floor constipation occurs when the muscles used to empty the rectum do not coordinate correctly. Biofeedback therapy with a trained pelvic floor professional can be more effective than simply adding laxatives when this is the cause.

How do I know if constipation has become impacted?

Possible fecal impaction signs include long lasting constipation, marked abdominal discomfort, bloating, nausea, loss of appetite, inability to pass normal stool, and sometimes watery stool leaking around the hard mass.

When is constipation an emergency?

Seek urgent medical help for constipation with severe or constant abdominal pain, repeated vomiting, a very swollen abdomen, inability to pass gas, fainting, or significant bleeding.
