Why Am I Bleeding After a Bowel Movement? Hemorrhoids (Piles): Symptoms, Causes & Treatment
Hemorrhoids, also called piles, are swollen veins in the lower rectum or around the anus. They are one of the most common anorectal conditions, affecting millions of people worldwide. Although hemorrhoids can cause pain, itching, bleeding, and discomfort, they are usually not dangerous and often improve with simple lifestyle changes and appropriate treatment.
Constipation, prolonged straining, pregnancy, obesity, and prolonged sitting are among the most common causes. Fortunately, most hemorrhoids can be managed without surgery.
This evidence-based guide explains the symptoms, causes, treatment options, prevention strategies, and when medical evaluation is necessary.
What Are Hemorrhoids?
Hemorrhoids are enlarged blood vessels located inside or around the anus and lower rectum.
Everyone has hemorrhoidal tissue, which helps maintain continence. Problems develop when these blood vessels become enlarged, inflamed, or prolapse.
Hemorrhoids are classified into two main types:
Internal Hemorrhoids
Internal hemorrhoids develop inside the rectum.
They are usually painless because they develop above the dentate (pectinate) line, where there are relatively few pain-sensitive nerves.
However, they may cause:
- Bright red bleeding during bowel movements
- Mucus discharge
- A feeling of incomplete emptying
- Prolapse (hemorrhoids that protrude outside the anus).
External Hemorrhoids
External hemorrhoids develop beneath the skin around the anus.
They may cause:
- Pain
- Swelling
- Itching
- Tenderness
- Difficulty sitting
A blood clot may occasionally develop inside an external hemorrhoid (thrombosed hemorrhoid), causing sudden severe pain and a firm bluish lump.
Symptoms of Hemorrhoids
Symptoms depend on the type and severity.
Common symptoms include:
- Bright red blood on toilet paper or in the toilet bowl
- Anal itching
- Burning around the anus
- Pain during bowel movements
- Swelling around the anus
- A lump near the anus
- Mucus discharge
- Feeling that the bowel has not emptied completely
Bleeding from hemorrhoids is usually bright red and most often occurs during or immediately after a bowel movement. Although internal hemorrhoids are the most common cause of painless rectal bleeding, external hemorrhoids may also bleed if they become irritated, thrombosed, or if the overlying skin cracks or ulcerates.
Hemorrhoids or Something More Serious?
Rectal bleeding should never be automatically assumed to be caused by hemorrhoids.
Although hemorrhoids are a common cause of bright red bleeding, similar symptoms may occur with:
- Anal fissures
- Inflammatory bowel disease (IBD)
- Colon polyps
- Colorectal cancer
- Diverticular disease
- Infectious colitis
Any new or persistent rectal bleeding should be assessed by a healthcare professional, especially in people over 45–50 years of age or those with a family history of colorectal cancer.
Hemorrhoids or Another Condition? Comparison Table
| Condition | Typical Symptoms | Bleeding | Pain | Other Clues |
|---|---|---|---|---|
| Hemorrhoids | Itching, swelling, lump around the anus, discomfort during bowel movements | Bright red blood on toilet paper or in the toilet after passing stool | Mild to moderate (external hemorrhoids can be painful, especially if thrombosed) | Symptoms often worsen with constipation, prolonged sitting, pregnancy, or straining. |
| Anal Fissure | Sharp, tearing pain during or after a bowel movement | Bright red blood, usually a few drops on the toilet paper | Severe, especially during and after bowel movements | Often caused by passing hard stools. A small tear may be visible near the anus. |
| Inflammatory Bowel Disease (Crohn’s Disease or Ulcerative Colitis) | Chronic diarrhea, abdominal pain, urgency, fatigue, weight loss | Blood may be mixed with the stool and can occur repeatedly | Abdominal pain is common; anal pain is less common unless there are fissures or fistulas | May be associated with fever, anemia, joint pain, mouth ulcers, or eye inflammation. |
| Colon Polyps | Usually no symptoms | May cause occasional bleeding, often unnoticed | Usually painless | Often discovered during routine colonoscopy. Some polyps can become cancerous over time. |
| Colorectal Cancer | Change in bowel habits, abdominal discomfort, unexplained weight loss, fatigue | Blood may be bright red or dark and mixed with the stool | Usually painless in the early stages | Persistent bleeding, iron-deficiency anemia, weight loss, or a family history should always be evaluated. |
| Diverticular Disease | Often painless; sometimes abdominal pain if inflamed | May cause sudden, sometimes heavy rectal bleeding | Usually painless unless diverticulitis develops | More common in older adults. |
| Infectious Colitis | Diarrhea, fever, abdominal cramps | Blood or mucus may be present | Cramping abdominal pain | Often develops after contaminated food, water, or recent travel. |
| Rectal Prolapse | A reddish mass protruding from the anus | Occasional bleeding or mucus | Discomfort rather than severe pain | More common in older adults and people with chronic constipation. |
🚩 When Rectal Bleeding Should Never Be Ignored
Although hemorrhoids are a common cause of bright red rectal bleeding, bleeding should never automatically be assumed to be caused by hemorrhoids, particularly if it is:
- Persistent or recurrent.
- Mixed with the stool rather than only seen on the toilet paper.
- Associated with unexplained weight loss.
- Accompanied by persistent diarrhea or changes in bowel habits.
- Associated with fever or severe abdominal pain.
- Occurring in adults over 45–50 years of age without a previous medical evaluation.
- Accompanied by iron-deficiency anemia or fatigue.
- Present in people with a family history of colorectal cancer or inflammatory bowel disease.
These symptoms require prompt medical assessment to exclude more serious conditions.
💊 Pharmacist’s Tip
Many people buy hemorrhoid creams without first confirming the cause of their symptoms. While hemorrhoids are common, not all rectal bleeding or anal pain is caused by hemorrhoids. Severe pain during bowel movements often suggests an anal fissure, while persistent bleeding associated with diarrhea, weight loss, or fatigue may indicate a more serious bowel condition. If your symptoms do not improve within one week, keep returning, or are accompanied by warning signs, consult your doctor rather than continuing to self-treat.
What Causes Hemorrhoids?
Hemorrhoids develop when pressure inside the veins of the rectum and anus increases.
Common causes include:
Chronic Constipation
Straining during bowel movements is one of the most important risk factors.
Chronic Diarrhea
Frequent diarrhea and repeated irritation may also contribute.
Pregnancy
Hormonal changes and pressure from the growing uterus increase the risk, particularly during the third trimester.
Obesity
Excess body weight increases pressure on the pelvic veins.
Sitting for Long Periods
Long periods of sitting, especially on the toilet, may increase pressure around the rectum.
Heavy Lifting
Repeated heavy lifting may increase abdominal pressure.
Low-Fiber Diet
A diet low in fiber often leads to harder stools and increased straining.
Risk Factors
The likelihood of developing hemorrhoids increases with:
- Age
- Pregnancy
- Obesity
- Sedentary lifestyle
- Chronic constipation
- Chronic diarrhea
- Family history
- Low-fiber diet
How Are Hemorrhoids Diagnosed?
Doctors usually diagnose hemorrhoids through:
- Medical history
- Physical examination
- Digital rectal examination
In some cases, additional investigations may be recommended, such as:
- Anoscopy
- Sigmoidoscopy
- Colonoscopy
These tests help rule out other causes of rectal bleeding.
When Should You See a Doctor?
Consult your doctor if:
- Bleeding continues despite treatment.
- You notice blood mixed with the stool.
- Pain is severe.
- A lump becomes extremely painful.
- Symptoms last longer than one week.
- You experience unexplained weight loss.
- Bowel habits change significantly.
Seek urgent medical attention if you develop heavy rectal bleeding, dizziness, fainting, or severe pain with fever.
Treatment of Hemorrhoids
Most hemorrhoids improve with simple lifestyle changes and over-the-counter treatments. The goals of treatment are to relieve pain, itching, swelling, and bleeding, while preventing future flare-ups by addressing the underlying cause.
Treatment depends on the type and severity of the hemorrhoids.
Lifestyle Changes
Lifestyle changes are the foundation of long-term hemorrhoid management.
Increase Your Fiber Intake
A high-fiber diet helps soften stools, making them easier to pass and reducing straining.
Adults should aim for approximately 25–38 grams of fiber daily.
Good sources include:
- Fruits
- Vegetables
- Whole grains
- Oats
- Beans
- Lentils
- Flaxseed
- Psyllium husk
Increase fiber gradually and drink plenty of water to reduce bloating.
Stay Hydrated
Adequate fluid intake helps keep stools soft.
Aim for approximately 1.5–2.5 liters of fluids daily, unless your healthcare professional has advised otherwise.
Avoid Straining
Do not sit on the toilet for long periods or strain excessively during bowel movements.
Go to the toilet when you first feel the urge.
Exercise
Regular physical activity promotes healthy bowel movements and helps reduce constipation.
Walking for 20–30 minutes daily may help.
Sitz Baths
Warm sitz baths may help relieve:
- Pain
- Itching
- Muscle spasm
- Swelling
Sit in warm (not hot) water for 10–15 minutes, several times daily, particularly after bowel movements.
Over-the-Counter Hemorrhoid Products
Several non-prescription products are available to relieve hemorrhoid symptoms. While these treatments can improve discomfort, they do not eliminate hemorrhoids or treat the underlying cause. Lifestyle changes remain essential to prevent recurrence.
| Product Type | Best For | Important Notes |
|---|---|---|
| Hydrocortisone cream | Itching, inflammation | Use for short periods (generally no more than 7 days unless advised otherwise). |
| Lidocaine products | Pain | Temporary symptom relief only. |
| Witch hazel pads | Mild irritation and itching | May soothe symptoms; evidence is limited. |
| Barrier creams (zinc oxide) | Skin protection | Useful when moisture or irritation is present. |
| Suppositories | Internal hemorrhoids | Reach inside the rectum more effectively than creams. |
| Fiber supplements | Prevention and recurrence | One of the most effective long-term strategies for reducing straining. |
| MPFF (diosmin + hesperidin) | Acute hemorrhoidal symptoms | May reduce pain, bleeding, and swelling as an adjunct to standard care. |
Hydrocortisone Creams
Hydrocortisone reduces inflammation, itching, and swelling.
They may be helpful for:
- Inflamed external hemorrhoids
- Itching
- Mild irritation
Because prolonged use may thin the skin, hydrocortisone creams should generally not be used for longer than 7 days unless advised by a healthcare professional.
Local Anesthetics
Products containing ingredients such as lidocaine provide temporary pain relief by numbing the affected area.
They are useful when:
- Sitting is painful.
- Bowel movements are uncomfortable.
- External hemorrhoids are very tender.
These products relieve symptoms but do not treat the underlying hemorrhoid.
Zinc Oxide and Barrier Creams
Barrier creams containing zinc oxide or similar protective ingredients help reduce irritation caused by moisture and friction.
They are particularly useful when hemorrhoids are associated with:
- Skin irritation
- Minor leakage
- Frequent bowel movements
Witch Hazel (Hamamelis)
Witch hazel has mild astringent and soothing properties.
Many people find it helpful for:
- Itching
- Mild irritation
- Burning
Scientific evidence is limited, but it is generally well tolerated.
Suppositories
Rectal suppositories may be more suitable for internal hemorrhoids, while creams and ointments are generally easier to apply to external hemorrhoids.
Some products combine:
- Hydrocortisone
- Local anesthetics
- Protectants
- Lubricants
Combination products may provide relief from several symptoms at the same time.
Oral Flavonoids
Micronized Purified Flavonoid Fraction (MPFF), containing diosmin and hesperidin, is widely used in many countries for hemorrhoidal disease.
Some clinical studies suggest that flavonoids may:
- Reduce pain
- Decrease bleeding
- Improve swelling
- Shorten the duration of acute hemorrhoid attacks
Although evidence is generally supportive, recommendations differ between clinical guidelines, and flavonoids are usually considered an adjunct to lifestyle measures and standard treatment, rather than a replacement for them.
Fiber Supplements
Fiber supplements are among the most effective long-term treatments for preventing recurrent hemorrhoids.
Examples include:
- Psyllium husk
- Methylcellulose
- Wheat dextrin
These supplements improve stool consistency and reduce straining.
When Is Surgery Needed?
Medical procedures may be recommended if hemorrhoids are large, prolapsed, or do not respond to conservative treatment.
Options include:
Rubber Band Ligation
Small rubber bands are placed around internal hemorrhoids to cut off their blood supply.
This is one of the most common office procedures.
Sclerotherapy
A solution is injected into the hemorrhoid, causing it to shrink.
Infrared Coagulation
Heat is used to shrink small internal hemorrhoids.
Hemorrhoidectomy
Surgical removal may be recommended for severe or recurrent hemorrhoids.
Although recovery can be uncomfortable, surgery provides the lowest recurrence rate for advanced hemorrhoids.
Hemorrhoids During Pregnancy
Hemorrhoids are common during pregnancy because hormonal changes and pressure from the growing uterus increase pressure on the rectal veins.
Most improve after childbirth.
Helpful measures include:
- High-fiber diet
- Adequate hydration
- Regular walking
- Avoiding constipation
- Sitz baths
Pregnant women should consult their healthcare professional before using hemorrhoid medications, including topical creams and suppositories.
Hemorrhoids in Children
Hemorrhoids are uncommon in children.
When they occur, they are often associated with:
- Chronic constipation
- Straining during bowel movements
- Low-fiber diets
Children with rectal bleeding should always be evaluated by a healthcare professional, as bleeding may have other causes such as anal fissures, polyps, or inflammatory bowel disease.
Parents should encourage:
- A fiber-rich diet.
- Adequate hydration.
- Regular toilet habits.
- Physical activity.

💊 Pharmacist’s Tip
Over-the-counter hemorrhoid creams can quickly relieve itching, pain, and swelling, but they should not be relied on as a long-term solution. If you find yourself repeatedly buying hemorrhoid treatments, it is worth addressing the underlying cause—most commonly constipation, prolonged straining, or chronic diarrhea. Fiber supplements, adequate hydration, and healthy bowel habits are often the most effective ways to prevent future flare-ups. If symptoms persist, recur frequently, or bleeding continues despite treatment, seek medical advice rather than continuing to self-treat.
Do hemorrhoids go away on their own?
Small hemorrhoids often improve with lifestyle changes and conservative treatment, although recurrence is common if the underlying cause is not addressed.
Can hemorrhoids bleed?
Yes. Both internal and external hemorrhoids can bleed. Internal hemorrhoids often cause painless, bright red bleeding during or immediately after a bowel movement. External hemorrhoids may also bleed, particularly if they become irritated, thrombosed, or if the skin over the hemorrhoid cracks. Although hemorrhoids are a common cause of rectal bleeding, persistent or unexplained bleeding should always be evaluated by a healthcare professional to exclude other conditions.
Are hemorrhoids dangerous?
Most hemorrhoids are not dangerous, but persistent rectal bleeding should always be evaluated to exclude other conditions.
Can constipation cause hemorrhoids?
Yes. Chronic constipation and repeated straining are among the most common causes.
Can diarrhea cause hemorrhoids?
Yes. Frequent diarrhea may irritate the anal area and contribute to hemorrhoid symptoms.
Is surgery always necessary?
No. Most hemorrhoids improve with lifestyle changes, fiber, and conservative treatment. Surgery is usually reserved for severe or persistent cases.
Can children get hemorrhoids?
Yes, but they are uncommon. Constipation is the most frequent cause.
