Rectal pain and bleeding are common but confusing problems. Many people assume it’s just piles, but the truth is that two conditions, haemorrhoids and anal fissures, cause similar symptoms while being very different in nature.
Haemorrhoids are swollen blood vessels around the rectum or anus, while anal fissures are tiny tears in the skin at the anal opening. Both can cause bleeding, discomfort, and worry, but their treatment and long-term outlook are not the same.
Understanding the difference matters because self-treatment without clarity can make things worse. This guide breaks down haemorrhoids vs anal fissures, covering symptoms, causes, treatment, prevention, and when you should see a doctor.
What Are Haemorrhoids?
Haemorrhoids are enlarged or swollen blood vessels inside the rectum or around the anus. They are like varicose veins, but in the bottom part of your body. Everyone has these blood vessels, it’s when they stretch too much or become irritated that they turn into a problem.
There are three main types:
- Internal haemorrhoids: They develop inside the rectum. You usually can’t see or feel them. They often cause painless bleeding during bowel movements. In some cases, they may bulge out (prolapse) through the anus, which can be uncomfortable.
- External haemorrhoids: They form under the skin around the anus. These are the ones people often notice because they can itch, burn, or cause swelling and a noticeable lump.
- Thrombosed haemorrhoids: They happen when a blood clot forms inside an external haemorrhoid. They can be extremely painful and may look bluish or purple.
Haemorrhoids are very common, studies suggest that at least half of all adults will experience them by age 50. They can come and go, flare up with constipation or straining, and sometimes linger as a chronic condition.
Common Symptoms of Haemorrhoids
- Bright red blood after bowel movements.
- Itching or irritation around the anus.
- Swelling or a lump near the anus.
- Discomfort, especially when sitting.
Causes of Haemorrhoids
- Straining during bowel movements.
- Chronic constipation or diarrhoea.
- Prolonged sitting on the toilet.
- Pregnancy and increased abdominal pressure.
- Obesity and a low-fibre diet.
What Is an Anal Fissure?
An anal fissure is not a swollen vein but a small tear in the thin, delicate skin (mucosa) lining the anus. Imagine the paper-like skin at the anal opening splitting open, much like a tiny paper cut, and you’ll understand why it hurts so much.
Anal fissures usually appear in the back part of the anus, where blood flow is slightly less, making it harder for the skin to heal. They can be:
- Acute fissures, which are new tears that may heal within a few weeks if bowel movements are softened.
- Chronic fissures, which are deeper, longer-lasting cracks that may not close on their own and sometimes form a small skin tag at the edge of the tear.
The main feature of a fissure is sharp, burning pain when passing stool, often described as “passing glass”. Pain can persist long after the bowel movement because the anal muscle (sphincter) goes into spasm. A fissure may bleed a little, leaving bright red streaks on toilet paper or stool, but bleeding is usually less than with haemorrhoids.
Anal fissures can affect anyone, but they are particularly common in people with chronic constipation, new mothers after childbirth, and those with conditions like Crohn’s disease.
Common Symptoms of Anal Fissure
- Sharp, cutting pain during bowel movements.
- Burning or throbbing pain lasting minutes to hours afterwards.
- Small amounts of bright red blood on toilet paper or stool.
- A visible crack or tear near the anus.
- Muscle spasm of the anal sphincter.
Causes of Anal Fissures
- Passing hard or large stools
- Chronic constipation or repeated straining
- Chronic diarrhoea
- Childbirth trauma
- Inflammatory bowel disease (Crohn’s disease)
Diagnosis of Haemorrhoids
- Medical History
The doctor asks about bleeding, lumps, itching, pain, and bowel habits. This helps rule out conditions that mimic haemorrhoids.
- Physical Examination
- Visual Exam: External haemorrhoids can often be diagnosed by simply looking at the anal area for swelling, lumps, or skin irritation.
- Digital Rectal Exam (DRE): The doctor gently inserts a lubricated, gloved finger into the rectum. This helps feel for internal haemorrhoids, abnormal growths, or other issues.
- Instrumental Exams
- Anoscopy: A small, lighted tube is inserted a few centimetres into the rectum. This gives a clear view of internal haemorrhoids that can’t be seen from the outside.
- Sigmoidoscopy: A longer, flexible tube with a light and camera checks the rectum and lower part of the colon. It’s useful if bleeding is unexplained or if more than haemorrhoids are suspected.
- Colonoscopy: A full examination of the colon using a flexible camera. This is recommended if you’re over 45, have persistent bleeding, have a family history of colon cancer, or have other warning signs. It helps rule out polyps, cancer, and other serious diseases.
Diagnosis of Anal Fissure
- Medical History
The doctor starts by asking about pain, bleeding, constipation, or diarrhoea. Details like childbirth or inflammatory bowel disease matter because they can trigger fissures.
- Physical Examination
- Positioning: You may be asked to lie on your side or stomach. This allows the doctor to gently inspect the anal area.
- Visual Inspection: A fissure often looks like a small cut in the skin. Fresh fissures appear as red cracks, while chronic ones may look deeper with thickened edges or a small skin tag.
- Gentle Palpation: The doctor may lightly touch the area to see if the anal muscle is tight, but they avoid pressing hard because it can be too painful.
- Further Tests
- Anoscopy: A short, smooth tube with light is inserted into the anus. It lets the doctor see inside for hidden fissures or other causes of bleeding.
- Examination Under Anaesthesia (EUA): If pain prevents a full exam, you may be given anaesthesia so the doctor can examine the area without discomfort.
- Colonoscopy: A flexible camera is used to inspect the entire colon, usually if you’re over 45 or if symptoms suggest another problem like cancer or polyps.
- Biopsy: A small tissue sample may be taken if the fissure looks unusual or is suspected to be linked to another disease.
Haemorrhoids vs Anal Fissure: How To Treat at Home?
Home treatment focuses on reducing pain, promoting healing, and preventing recurrence. Many mild cases improve without medical procedures.
- High-Fibre Diet: Eat fruits, vegetables, whole grains, and legumes to make stools softer and easier to pass. Softer stools reduce strain on the anal area.
- Stay Hydrated: Drink minimum 8 to 10 glasses of water daily to prevent hard stools.
- Stool Softeners: Over-the-counter fibre supplements or laxatives can help in passing stools without pain.
- Warm Sitz Baths: Sitting in warm water for 10-15 minutes, 2-3 times a day, relaxes the anal muscles, relieves pain, and improves blood flow to help healing.
- Good Toilet Habits: Avoid sitting on the toilet for long periods and respond promptly to the urge to pass stool.
- Cold Compresses: Applying ice packs for a few minutes can temporarily reduce swelling and numb pain in external haemorrhoids.
Medical Treatments for Haemorrhoids
When home remedies are insufficient, medical treatments may be needed.
1. Over-the-Counter Creams and Ointments
- Hydrocortisone Creams: Reduce inflammation and itching around the anus. Apply as directed, usually 1-2 times per day.
- Witch Hazel Pads: Calm irritation and provide a cooling effect for external haemorrhoids.
2. Rubber Band Ligation
A small rubber band is placed around the base of an internal haemorrhoid. This cuts off the blood supply, causing the haemorrhoid to shrink and fall off within a few days.
3. Sclerotherapy
A chemical solution is injected into the haemorrhoid, causing it to shrink. This is usually used for small internal haemorrhoids that bleed but do not prolapse.
4. Infrared Coagulation
A special device uses heat (infrared light) to cut off the blood supply to the haemorrhoid. It shrinks and eventually disappears. This is quick and minimally painful.
5. Haemorrhoidectomy
Haemorrhoidectomy is the surgical removal of haemorrhoids, usually for large or hanging ones. The surgeon takes out the swollen veins and nearby tissue to help prevent them from coming back. Recovery can take 1-2 weeks, so using stool softeners and managing pain is very important during this time.
6. Haemorrhoidal Artery Ligation (HALO/THD)
Haemorrhoidal artery ligation is a simple procedure for treating internal haemorrhoids. It uses a Doppler device to find the arteries that supply blood to the haemorrhoid. These arteries are tied off, which reduces blood flow and helps the haemorrhoid shrink. The procedure often includes repositioning the haemorrhoid back into the anal canal, called transanal haemorrhoidal dearterialisation (THD). This method is less painful than traditional surgery and allows for a quicker recovery.
7. Laser Haemorrhoidoplasty (LHP)
Laser haemorrhoidoplasty is a modern technique that uses a laser to treat swollen haemorrhoids. The laser energy shrinks and seals the veins without making large cuts. This procedure is minimally invasive and is often performed with local anaesthesia. It reduces pain after the surgery, allows for quicker recovery, and keeps normal tissue intact.
Medical Treatments for Anal Fissure
If home care doesn’t heal a fissure, doctors may use procedures to relax the anal muscle and promote healing.
1. Over-the-Counter and Prescription Ointments
- Numbing Creams: Temporary relief from sharp pain during bowel movements.
- Nitroglycerin Ointment: Helps relax the anal sphincter and increases blood flow to the fissure, speeding healing.
- Calcium Channel Blocker Ointments (Diltiazem/Nifedipine): Also relax the anal muscle and reduce spasm, allowing the fissure to close naturally.
2. Botox Injections
Botox is injected into the anal sphincter muscle. This temporarily relaxes the muscle, reducing spasm and pain, and helps the fissure heal within a few weeks.
3. Lateral Internal Sphincterotomy
A surgical procedure for chronic fissures that don’t respond to other treatments. A small cut is made in part of the anal sphincter muscle to relieve pressure. This allows blood flow to improve and the fissure to heal.
When to See a Doctor
It’s important to know when symptoms require professional medical attention rather than home care alone.
- Heavy or persistent rectal bleeding.
- Severe pain during or after bowel movements.
- A lump near the anus that does not go away.
- Chronic constipation or diarrhoea.
- Age over 45 or family history of colon cancer with new rectal bleeding.
- Signs of infection (swelling, pus, fever).
- Symptoms not improving with home care within 1-2 weeks.
Final Thoughts
Haemorrhoids and anal fissures may share some symptoms, but they are very different conditions. Haemorrhoids come from swollen veins, while fissures are tears in the skin. Recognising the difference helps in getting the right treatment early and avoiding unnecessary suffering. Most cases improve with lifestyle changes and simple treatments, but chronic or severe symptoms need medical evaluation.
Frequently Asked Questions
1. How do I know if it’s a haemorrhoid or a fissure?
External haemorrhoids usually create a visible lump near the anus, while internal haemorrhoids may not be seen but can cause bleeding. Anal fissures rarely cause swelling, but you might notice a small tear during examination.
2. Can haemorrhoids cause headaches?
Severe haemorrhoids can sometimes cause anaemia from blood loss, which may lead to tiredness, dizziness, headaches, or a fast heartbeat.
3. What hurts more, fissures or haemorrhoids?
Anal fissures usually cause sharper pain, about 90% of fissures are painful. Haemorrhoids may or may not hurt, and their pain is often milder or constant.
4. When should I worry about haemorrhoids?
Seek a doctor if bleeding persists, is dark or unusual, or comes with bowel changes. Also consult if symptoms don’t improve after a week of home care, or if you notice infection signs, fever, or chills.
