Yes, haemorrhoids can cause or worsen constipation. They are linked in two ways: constipation can lead to haemorrhoids, and having haemorrhoids can make constipation worse. Pain and discomfort may lead people to delay bowel movements, causing stools to harden and become more difficult to pass.
In some cases, swollen haemorrhoids can even narrow the anal canal and partially obstruct stool passage. On the other hand, constipation through straining and hard stools is one of the biggest risk factors for developing haemorrhoids in the first place. This creates a cycle that can be difficult to break.
Understanding how haemorrhoids and constipation are connected is important to find the right treatment and lasting relief.
How Haemorrhoids Cause Constipation?
Haemorrhoids can cause constipation, and they do so in several ways. The most common is what doctors call functional constipation, which happens even without a clear physical blockage. With haemorrhoids, this often follows a clear pattern:
- Pain during bowel movements – Inflamed or thrombosed haemorrhoids can make passing stool painful.
- Stool holding – To avoid that pain, many people consciously or unconsciously delay going to the toilet.
- Hardening of stools – The longer the stool stays in the colon, the more fluid is absorbed, leaving it dry, hard, and much more difficult to pass.
- Obstruction – When haemorrhoids become large or slip outside the anus, they can narrow the anal canal and make it harder for stool to pass through.
- Incomplete emptying – Haemorrhoids can create a constant feeling that the bowels aren’t fully cleared, which makes people strain more during bowel movements.
- Muscle tightening – The pain from haemorrhoids can cause the muscles around the anus to spasm or tighten, and this prevents the rectum from relaxing enough to let stool pass easily.
Haemorrhoids can also cause secondary constipation, which occurs when there is an actual physical or medical reason for stool retention. For example:
- Prolapsed haemorrhoids (when internal haemorrhoids slip out of the anus) can narrow the passage and make evacuation difficult.
- After haemorrhoid surgery, some people develop narrowing of the anal canal (anal stenosis) or experience slowed bowel movements due to anaesthesia or opioid painkillers used during recovery.
In both functional and secondary constipation, the end result is the same: haemorrhoids set off a cycle of pain, stool retention, and harder bowel movements, making constipation both more likely and more severe.
The Link Between Haemorrhoids and Constipation
Hemorrhoids are enlarged veins located in the rectum or anus. Constipation happens when stools become hard, dry, and difficult to pass. Both conditions are closely connected and often appear together.
- Constipation leads to haemorrhoids: Straining during bowel movements puts added pressure on the veins in the anal canal, causing them to swell and become inflamed. Passing hard stools also irritates and damages the delicate tissue around the anus, which makes haemorrhoids more likely.
- Haemorrhoids contribute to constipation: Once haemorrhoids develop, they can make bowel movements painful. This pain often leads people to hold back stools, which makes them harder and drier the longer they stay in the colon. In more severe cases, large or prolapsed haemorrhoids can partially block the anal canal and physically slow stool passage.
This shows that constipation and haemorrhoids have a cyclical and interconnected relationship. Constipation increases the risk of haemorrhoids, while haemorrhoids can make constipation worse by causing pain or obstruction. Each condition can both trigger and intensify the other, creating a cycle that can only be broken with proper treatment of both.

Symptoms of Haemorrhoids vs. Constipation
Because haemorrhoids and constipation often overlap, it helps to know the full range of symptoms of each.
Haemorrhoid symptoms may include:
- Bright red bleeding during or after bowel movements.
- Pain, swelling, or a lump around the anus.
- Itching, burning, or irritation in the anal area.
- A heavy or full feeling in the rectum, even after passing stool.
- Mucus discharge that can stain underwear.
- Difficulty cleaning the area after a bowel movement.
- Prolapse (internal haemorrhoids pushing out of the anus).
- Thrombosis (sudden, severe pain and swelling from a blood clot in an external haemorrhoid).
Constipation symptoms may include:
- Fewer than three bowel movements per week.
- Hard, lumpy, or dry stools.
- Straining or excessive effort during bowel movements.
- A sensation of incomplete bowel movement.
- Abdominal bloating, discomfort, or cramping.
- A feeling of blockage in the rectum.
- Needing to use manual manoeuvres (like pressing on the abdomen or using fingers) to help pass stool.
When constipation and haemorrhoids happen together, they can make each other worse. Constipation can strain and irritate haemorrhoids. In turn, haemorrhoids can cause pain and fear, which can lead to more constipation.
How Constipation Worsens Haemorrhoids?
Constipation doesn’t just trigger haemorrhoids; it also makes existing ones worse. The harder the stools and the more you strain, the more pressure builds in the rectal veins.
Over time, this pressure stretches the veins, causing them to swell, inflame, and sometimes even tear the delicate lining of the anal canal. Hard stools can scrape against existing haemorrhoids, making them more painful and increasing bleeding.
In some cases, constipation can also cause small cracks in the skin around the anus, known as anal fissures, which add to the pain and make bowel movements even harder. This creates a vicious cycle where constipation worsens haemorrhoids, and haemorrhoids then worsen constipation.
Here is How Constipation Leads to Worsening Haemorrhoids:
- Straining: Hard stools make you push harder to pass them. This straining raises rectal pressure and directly aggravates haemorrhoids.
- Increased pressure: The veins inside the rectum and anus expand under this pressure, making them swollen and inflamed.
- Hard stools: Dry, lumpy stools scrape against the anal lining and irritate haemorrhoids, leading to bleeding and inflammation.
- Prolonged stool retention: The longer the stool sits in the colon, the harder it gets. Passing it becomes more traumatic to the already swollen veins.
- Vein damage: Constant stretching weakens the veins, turning them into haemorrhoids or making existing ones larger.
- Irritation: Hard, dry stools scrape the anal canal, inflame haemorrhoids further, and can even cause bleeding or small tears.
- The cycle: Pain and discomfort from haemorrhoids or fissures make you hesitant to pass stool, which leads to more stool retention, harder stools, and worsening constipation.
What Contributes to Constipation and the Worsening of Haemorrhoids?
- Low-fibre diet: Too little fibre from fruits, vegetables, and whole grains leaves stools small, dry, and difficult to pass.
- Poor hydration: Without enough water, stools dry out and harden.
- Lack of physical activity: A sedentary lifestyle slows bowel movements, increasing the risk of constipation.
- Ignoring bowel urges: Holding back the urge to go allows more water to be absorbed from stool, making it harder and drier.
How To Ease Constipation Linked To Haemorrhoids?
Breaking the cycle of constipation and haemorrhoids means treating both at the same time. Small but consistent changes can make bowel movements easier and reduce haemorrhoid flare-ups.
1. Boost Fibre Intake
Aim for at least 25 to 30 grams of fibre daily. Good sources include fruits, vegetables, beans, lentils, oats, and whole grains. Fibre adds bulk and softens stools, making them easier to pass. This reduces straining and protects the anal veins from further swelling.
2. Stay Well Hydrated
Drink 6 to 8 glasses of water every day. Proper hydration prevents stools from becoming dry and hard, which makes passing them less painful and less likely to irritate haemorrhoids.
3. Limit Trigger Foods
Cut back on spicy, greasy, and heavily processed foods, as they can irritate the digestive system and sometimes worsen constipation. Focus instead on a balanced diet rich in natural, unprocessed foods.
4. Keep Moving
Regular exercise, like taking a daily walk, helps keep your intestines active and maintains healthy bowel function. Activities like swimming, cycling, or yoga can be especially helpful in preventing sluggish digestion.
5. Practise Better Toilet Habits
- Go as soon as you feel the urge; don’t hold it in.
- Avoid sitting too long on the toilet, which increases pressure in the anal area.
- Use a small footstool to raise your knees, placing the rectum in a more natural position for easier evacuation.
6. Comfort and Medical Support
- Sitz baths: Sitting in a warm, shallow bath for 10-15 minutes can relieve pain, reduce inflammation, and relax anal muscles.
- Over-the-counter creams and suppositories: These reduce swelling and pain, making bowel movements less stressful.
- Stool softeners or mild laxatives: These can be used short-term under medical advice to prevent straining.
By consistently following these steps, most people see improvements in both constipation and haemorrhoid symptoms. Managing bowel health directly reduces the risk of recurrence.
When to See a Doctor?
Most cases of haemorrhoids and constipation improve with lifestyle changes, but medical attention is important if you notice:
- Persistent or heavy rectal bleeding.
- Severe anal pain or swelling that does not improve.
- A lump around the anus that doesn’t go away.
- Ongoing constipation despite dietary and lifestyle changes.
- Unexplained weight loss, fever, or sudden changes in bowel habits.
A doctor can rule out other conditions, such as fissures, infections, polyps, or colorectal cancer, and recommend treatments ranging from minimally invasive procedures (like rubber band ligation) to surgery in severe cases.
Final Thoughts
Haemorrhoids and constipation are connected; constipation can trigger haemorrhoids, while haemorrhoids can worsen constipation. This cycle can persist if not addressed. Simple lifestyle changes, like increasing fibre intake, staying hydrated, exercising regularly, and managing pain, can help. If symptoms don’t improve, seeking medical help is important. Addressing both issues together is the most effective way to find relief and prevent recurrence.
Frequently Asked Questions
1. Can haemorrhoids really cause constipation?
Yes. Pain, swelling, and sometimes physical blockage from haemorrhoids can delay bowel movements, which leads to constipation.
2. How do I know if my constipation is from haemorrhoids or something else?
If constipation is accompanied by anal pain, bleeding, or a lump around the anus, haemorrhoids may be playing a role. A doctor can confirm this through an exam.
3. What’s the fastest way to relieve constipation with haemorrhoids?
Short-term relief comes from stool softeners, warm sitz baths, and haemorrhoid creams. Long-term relief requires consistent fibre intake, hydration, and active habits.
4. Can haemorrhoids go away on their own if I fix constipation?
Small haemorrhoids often shrink once constipation is managed. Larger or persistent haemorrhoids may need medical treatment.
5. Can haemorrhoids block bowel movements?
Yes. In some cases, very large or prolapsed haemorrhoids can narrow or block the anal canal. This can make it difficult or even impossible to pass stool normally.
6. How long does constipation from haemorrhoids last?
Mild haemorrhoid-related constipation often eases within a few days, but more severe cases can last for several weeks. If things don’t improve after 2-3 weeks, it’s a good idea to see a doctor for proper treatment.
