Constipation: How To Fix It

Quick Relief for Constipation: What to Do Right Now

If you want the best chance of getting relief today, work through this in order. Do not strain; straining can worsen symptoms and can lead to haemorrhoids.

The fastest, safest steps (try in this order)

• Have a warm drink; some people find that it helps start a bowel movement, and warm beverages are often recommended as a practical tip in NHS hospital guidance.
• Drink extra fluids throughout the day, especially if your stools are hard.
• Use a footstool and lean forward on the toilet. Aim for a more squat-like posture to make passing stool easier.
• Go for a short walk; gentle movement can help wake up the gut.
• If you still cannot go, consider an OTC laxative from the pharmacy. Guidance usually recommends lifestyle changes first, then a laxative if these do not help.

Quick relief options table

Option	When it helps most	Typical speed	Notes
Warm drink (tea, coffee, warm water)	When you feel “stuck” but otherwise well	Same day for some people	Warm drinks may stimulate a bowel movement. Avoid excess caffeine if it makes you dehydrated.
Extra fluids	Hard, dry stools	Hours to days	Fluids help soften stool and increase gradually as you also increase fibre intake.
Toilet posture (footstool, lean forward)	Straining, incomplete emptying	Same day	Good posture can reduce straining. Do not force it
Gentle movement (walking)	Sluggish bowels, routine changes	Same day to a few days	Often recommended as part of first-line self-care (nhs.uk)
OTC laxative from a pharmacy	When lifestyle steps have not worked	Depends on type	Bulk forming and osmotic options often take 2 to 3 days, stimulant laxatives may work within 6 to 12 hours (NHS inform)

How to Know If You Are Constipated

Constipation is not only about how often you pass stool, but also about a change from what is normal for you, combined with difficulty or discomfort when going to the toilet.

You may be constipated if one or more of the following apply:

• You are passing stool less often than usual, commonly fewer than three times per week
• Your stools are hard, dry, or lumpy
• You need to strain or spend a long time on the toilet
• You feel like your bowel has not fully emptied
• You feel blocked or uncomfortable in your lower abdomen

Healthcare guidance in the UK and Europe focuses on symptoms and stool consistency, not just frequency. Someone who goes daily can still be constipated if stools are hard and painful to pass, while another person may usually go every few days without difficulty.

Stool consistency can be a helpful clue

Doctors often describe stool types to help identify constipation:

• Hard pellets or substantial stools often suggest slow bowel movement
• Large, dry stools may indicate dehydration or low fibre intake
• Normal stools are soft, smooth, and easy to pass without straining

If constipation is new, persistent, or clearly different from your usual pattern, it is essential to pay attention to accompanying symptoms, which are covered later in the red flags section.

Common Causes and Triggers of Constipation

Constipation usually happens when stool moves too slowly through the bowel or when too much water is removed from it. Finding the cause matters because treatment works best when it targets the primary trigger.

Diet and fluid-related causes

• Low fibre intake, diets low in whole grains, vegetables, fruits, and legumes can lead to smaller, harder stools.
• Not drinking enough fluids can cause dehydration, which makes the stool dry and hard to pass.
• Sudden diet changes, for example, starting a strict diet or changing eating habits.

UK and European healthcare guidance often recommends fibre and fluid intake as the first steps to take when constipation starts.

Lifestyle and routine changes

• Reduced physical activity, movement helps the bowels work properly.
• Ignoring the urge to go, waiting too long lets the stool become harder.
• Travel or disrupted routines, changes to meals, sleep, or toilet access can slow the bowels.
• The gut is sensitive to stress and changes in routine.

Medicines that can cause constipation

Some medicines are known to slow bowel movements. Common examples include:

• Pain relief medicines, mainly opioid based ones.
• Iron supplements.
• Certain antidepressants.
•  
• Medicines for bladder problems.
• Some blood pressure medicines.

If constipation starts soon after a new medicine, this should be checked with a healthcare professional instead of using laxatives again and again.

Medical conditions linked to constipation

Most constipation is linked to lifestyle, but it can also be connected to:

• Irritable bowel syndrome with constipation.
• Slow transit constipation.
• Pelvic floor coordination problems.
• Hormonal changes, including pregnancy or thyroid conditions.

Constipation that lasts a long time, gets worse, or comes with other worrying symptoms should not be treated on your own without medical advice.

Common causes at a glance

Cause	How it contributes to constipation	What may help
Low fibre diet	Smaller, harder stools	Gradual fibre increase
Dehydration	The stool becomes dry	Increase daily fluid intake
Inactivity	Reduced bowel stimulation	Gentle daily movement
Ignoring urge	Stool hardens in the bowel	Respond to the urge promptly
Certain medicines	Slowed gut movement	Medical review, alternatives

 

Toilet Habits That Can Improve or Worsen Constipation

Your toilet habits can contribute to constipation more than many people think. Small changes in posture, timing, and routine can make it easier to go and help stop constipation from becoming a long-term problem.

Correct toilet posture for easier bowel movements

Modern toilets put the body in a seated position. This can make it harder for stool to pass. A more natural position can help.

Simple posture tips:

• Place your feet on a small footstool.
• Lean slightly forward with your elbows on your thighs.
• Relax your stomach and let it push out naturally.
• Keep your back straight, do not slump.

This position lines up the bowel better, which can reduce straining and help you empty more fully.

Why forcing a bowel movement makes constipation worse

Straining can feel like the only option, but forcing stool can:

• Increase pressure on the pelvic floor muscles.
• Lead to haemorrhoids or small tears around the anus.
• Interfere with standard bowel signals over time.

If nothing happens after a short time, it is better to stand up, move around, and try again later rather than forcing it.

Avoid spending long periods on the toilet.

Sitting on the toilet for a long time, especially while using a phone or reading, increases pressure and can worsen symptoms. Try to:

• Keep toilet time short.
• Go only when you feel the urge.
• Avoid sitting on the toilet out of habit.

Building a regular bowel routine

Many people find it helpful to train their bowels by:

• Going to the toilet at the same time each day, often after breakfast.
• Take your time, without rushing or being distracted.
• Going as soon as you feel the urge.

Over time, this routine can help your bowels work more naturally and reduce the need for laxatives.

High Fibre Diet for Constipation Relief

Dietary fibre helps keep stools soft and bulky, making them easier to pass. Many cases of constipation improve significantly once fibre intake increases. Fibre should be increased slowly to avoid bloating and discomfort.

How fibre helps constipation

Fibre adds bulk to stool and helps it hold water. This makes bowel movements easier and helps the gut work regularly. UK and European healthcare guidance recommends fibre as a first-line treatment for constipation.

There are two main types of fibre:

• Soluble fibre absorbs water and helps soften stool.
• Insoluble fibre adds bulk and helps stool move through the bowel.

Having a mix of both works best.

High fibre foods to include

Try to get fibre from whole foods rather than only using supplements.

Good fibre-rich foods include:

• Vegetables such as broccoli, carrots, peas, and leafy greens.
• Fruits, especially apples, pears, berries, and prunes.
• Whole grains like oats, wholemeal bread, brown rice, and wholegrain cereals.
• Legumes, including lentils, chickpeas, and beans.
• Seeds such as flax and chia.

Dried fruits can help, but keep portions small because they are high in natural sugar.

Increase fibre gradually to avoid bloating

Increasing fibre too fast can cause:

• Gas
• Bloating
• Stomach cramps

To help prevent this:

• Increase fibre slowly over one to two weeks.
• Drink plenty of fluids with fibre.
• Spread fibre across meals instead of eating it all at once.

If bloating becomes uncomfortable, reduce fibre slightly, then increase it more slowly.

Fibre and fluids go together.

Fibre works best when you also drink enough fluids. Without enough to drink, fibre can make constipation worse instead of better. Try to drink regularly throughout the day, especially when you are increasing your fibre intake.

Fibre tips at a glance

Tip	Why it matters
Choose whole foods	Provide both soluble and insoluble fibre
Increase gradually	Reduces gas and bloating
Drink fluids	Helps fibre soften stool
Spread intake	Easier on digestion

Fibre Supplements and OTC Options

If diet changes are not enough, fibre supplements and other over-the-counter options from a pharmacy can help. These are often suggested before using stronger treatments, especially for mild to moderate constipation.

Fibre supplements for constipation

Fibre supplements are also called bulk-forming laxatives. They work by soaking up water in the bowel, making stools bigger and easier to pass.

Commonly used fibre supplements include:

• Psyllium-based products
• Methylcellulose-based products

These are usually safe for regular use when taken as directed and with enough fluids.

What to expect when using fibre supplements

• They do not work straight away.
• Improvement is often seen within 2 to 3 days.
• They work best when taken every day.
• Drinking enough fluids is very important.

Some people may notice gas or bloating, especially in the first few days.

Other standard OTC constipation options

If fibre supplements do not help or are not suitable, a pharmacist may suggest other OTC options, based on your symptoms.

These may include:

• Osmotic laxatives, which pull water into the stool.
• Stool softeners help keep stools moist.
• Short-term stimulant laxatives are used when other options have not worked.

These should be used as advised and not used long-term without medical guidance.

Fibre supplements vs other OTC options

Option type	How it works	Typical time to work	Best suited for
Fibre supplements (bulk forming)	Increase stool bulk and water content	2 to 3 days	Mild or ongoing constipation
Osmotic laxatives	Draw water into the stool	1 to 3 days	Hard stools, dehydration-related constipation
Stool softeners	Increase moisture in stool	1 to 2 days	Painful or dry stools
Stimulant laxatives	Stimulate bowel contractions	6 to 12 hours	Short-term use when other options fail

Important safety points

• Avoid using more than one laxative at the same time unless advised.
• Long-term daily use of stimulant laxatives is usually not recommended.
• If constipation does not improve after several days of OTC treatment, further assessment is advised.

Laxatives Explained, Types and How Long They Take to Work

Laxatives can help when diet, fluids, and fibre have not eased constipation. The most important thing is choosing the right type and using it correctly. In the UK and Europe, guidance uses a step-by-step approach, starting with gentler options before moving on to stronger ones.

Different laxatives work in various ways, and how quickly they work can vary.

Bulk-forming laxatives

These are often the first choice for ongoing constipation.

• Increase stool size by absorbing water.
• Help the bowel move more naturally.
• Need enough fluids to work properly.

They are usually safe for regular use, but work slowly rather than straight away.

Osmotic laxatives

These laxatives pull water into the bowel. This softens stool and makes it easier to pass.

• Helpful when stools are hard or dry.
• Often used if bulk-forming laxatives do not help.
• It can cause bloating or cramps in some people.

Stimulant laxatives

Stimulant laxatives cause bowel muscles to contract.

• Used when other laxatives have not worked.
• It can give faster relief.
• Best used for short periods only.

Using them too often can make the bowel less responsive over time.

Rectal laxatives (suppositories or enemas)

These are usually used only in certain situations.

• Work directly in the rectum.
• Often act quickly.
• Not meant for regular use without medical advice.

They may be used when stool is stuck in the lower bowel or when oral treatments have not worked.

Laxative types comparison table

 

Laxative type	How it works	Typical time to work	When it is usually used	Important notes
Bulk forming	Adds bulk and holds water in stool	2 to 3 days	First line for ongoing constipation	Drink plenty of fluids
Osmotic	Draws water into the bowel	1 to 3 days	Hard or dry stools	May cause bloating
Stimulant	Stimulates bowel movement	6 to 12 hours	Short-term relief	Avoid long-term use
Rectal options	Softens or stimulates locally	Minutes to hours	Stool stuck in the rectum	Use with caution

Choosing the right laxative

• Start with the gentlest option.
• Give it enough time to work before changing to another.
• Avoid using more than one laxative at the same time unless advised.
• Get medical advice if constipation becomes frequent or does not improve.

Prescription Treatments for Chronic Constipation

Prescription treatments are usually used only when constipation is long-lasting, severe, or has not improved with lifestyle changes and OTC options. These treatments are not for quick relief and are usually part of a longer-term plan.

When prescription treatment may be considered

A healthcare professional may consider prescription treatment if:

• Constipation has lasted several weeks or longer.
• Symptoms affect daily life or comfort.
• OTC laxatives have not helped when used correctly.
• Constipation is linked to another condition, such as IBS with constipation or slow transit constipation.

Before prescribing, clinicians usually check diet, fluid intake, physical activity, toilet habits, and any medicines that could be causing constipation.

How prescription treatments work

Prescription medicines for constipation can work in different ways, including:

• Increasing bowel fluid to soften stool.
• Stimulating bowel movement through specific gut signals.
• Helping the bowel muscles work together more effectively.

These medicines aim to improve regular bowel habits over time, not to cause fast bowel movements.

What to expect from prescription treatment

• Relief is gradual and may take days or weeks.
• Treatment is reviewed and adjusted if symptoms do not improve.
• Regular follow-up helps limit side effects and avoid long-term problems.

Prescription treatment does not replace healthy habits. Diet, fluids, movement, and good toilet routines are still important.

Important safety points

• Prescription constipation medicines should only be used with medical supervision.
• They are not suitable for everyone.
• New, sudden, or worsening symptoms should be rechecked constantly.

Can Probiotics Help With Constipation?

Probiotics are live microorganisms that may help gut health by improving the balance of bacteria in the digestive system. In some people, changes in gut bacteria are linked to constipation, bloating, and changes in bowel habits.

How probiotics may help

Probiotics may:

• Help make stools softer.
• Increase the frequency of bowel movements in some people.
• Support bowel movement over time.

European guidance notes that probiotics can help some people, especially those with functional constipation or IBS-related constipation. Results vary, and they do not work for everyone.

What to expect if you try probiotics

• Probiotics do not work straight away.
• It may take 2 to 4 weeks to notice any change.
• Any benefit is usually mild rather than dramatic.

Some people notice no improvement at all.

Who may benefit most

Probiotics may be worth trying if:

• Constipation is mild or moderate.
• You also have bloating or gas.
• Other lifestyle steps are already in place.

They are less likely to help if constipation is mainly due to low fluid or fibre intake, or to certain medicines.

Choosing and using probiotics

• Choose products made for digestive health.
• Take them every day for several weeks.
• Try one product at a time to see if it helps.

If symptoms get worse, stop taking the probiotic and review other possible causes.

Probiotics, fibre, and laxatives

Probiotics do not replace fibre, fluids, or laxatives when these are needed. They may be used alongside other treatments as part of an overall bowel care plan.

How Long Does Constipation Usually Last?

How long constipation lasts depends on the cause and on how quickly it is treated. In many cases, symptoms improve within a few days once the proper steps are taken.

Occasional constipation

Short-term constipation caused by diet changes, travel, dehydration, or changes to routine often improves:

• Within 1 to 3 days after drinking more fluids and eating more fibre.
• Within a few days, once everyday routines return.
• After a bowel movement, discomfort usually eases quickly.

Most people get constipation now and then, and it usually is not a sign of a serious problem.

Constipation that takes longer to improve

Constipation may last longer if:

• Fibre intake has been low for a long time.
• You are not drinking enough fluids.
• Physical activity is low.
• You are taking medicines that cause constipation.

In these cases, improvement may take several days to a couple of weeks. This is common when using fibre supplements or osmotic laxatives, which work slowly.

Ongoing or recurrent constipation

If constipation:

• Lasts for several weeks.
• Keeps coming back despite lifestyle changes.
• Needs frequent use of laxatives.

It may be classed as chronic constipation and should be checked to find the cause and plan longer-term care.

When duration becomes a concern

You should seek medical advice if you experience constipation:

• Does not improve after about a week of proper self-care.
• Gets worse instead of better.
• Comes with new or unusual symptoms.

These situations are explained further in the red flags section below.

Red Flags: When to Seek Medical Help Urgently

Most constipation is not severe, but some symptoms can be a sign of a more urgent problem. These warning signs should not be ignored and should not be treated with home remedies or repeated laxative use alone.

Seek medical advice urgently if you have constipation along with:

• Severe or ongoing tummy pain, especially if it is getting worse.
• Not being able to pass gas at all can suggest a blockage.
• Blood in your stool or bleeding from the back passage.
• Black or tar-like stools, which can be a sign of bleeding higher up in the gut.
• Ongoing nausea or vomiting.
• A sudden change in bowel habits that does not settle.
• Unexplained weight loss.
• Constipation that keeps getting worse even with treatment.

These symptoms need prompt medical assessment to rule out conditions that may require urgent care.

Red flag symptoms at a glance

 

Symptom	Why it matters	What to do
Severe or worsening pain	May indicate obstruction or inflammation	Seek urgent medical advice
Inability to pass gas	Possible bowel blockage	Urgent assessment needed
Blood in stool	Could indicate bleeding or other conditions	Do not self-treat
Black stools	Possible internal bleeding	Urgent medical review
Persistent vomiting	Risk of dehydration or obstruction	Seek immediate advice
Sudden bowel habit change	May signal underlying illness	Medical assessment recommended
Unexplained weight loss	Possible systemic condition	Prompt evaluation needed

Do not delay care

Using laxatives or home remedies when red flag symptoms are present can delay diagnosis and make outcomes worse. If any of the above symptoms apply, constipation should be evaluated by a healthcare professional as soon as possible.

Preventing Constipation in the Future

Once constipation improves, the next step is stopping it from coming back. Long-term prevention focuses on helping the bowels work normally, not on regular laxative use.

Build a bowel-friendly daily routine.

Regular habits help train your bowels to work better.

Key routine tips:

• Go to the toilet when you feel the urge, do not wait
• Take your time, especially after meals.
• Try to go at the same time each day, often after breakfast.
• Avoid sitting on the toilet without a real urge.

Being consistent helps keep healthy bowel reflexes.

Maintain adequate fibre and fluid intake

Prevention works best when fibre and fluids are balanced.

• Include fibre at each meal rather than all at once.
• Drink regularly throughout the day, not just when thirsty.
• Drink more if you increase fibre or exercise.
• If fibre causes bloating, reduce slightly and increase more slowly.

Stay physically active

Regular movement helps the bowels move.

You do not need challenging exercise. Helpful activities include:

• Daily walking.
• Light stretching.
• Gentle movement spread through the day.

Even small amounts of movement can lower the risk of constipation.

Review medicines if constipation keeps returning.

If constipation started after a new medicine or keeps getting worse, it may need review. Changing the dose, timing, or type of medicine can sometimes help without needing long-term laxatives.

Manage common triggers

Be prepared during situations that often cause constipation:

• Travel, drink more fluids, and keep to a regular meal schedule.
• Stressful times, focus on routine and movement.
• Diet changes, increase fibre slowly.
