Constipation can make every bowel movement feel like a struggle. When hard stools, repeated straining, and long periods on the toilet become routine, hemorrhoids may develop or existing hemorrhoids may become more irritated.
You might notice itching, swelling, discomfort, or a small amount of bright red blood after passing stool. These symptoms are common, but rectal bleeding should not automatically be blamed on hemorrhoids—especially if it is new, persistent, or accompanied by other symptoms.
The encouraging part is that mild hemorrhoid symptoms often improve when you reduce straining and make stools softer and easier to pass.
What Are Hemorrhoids?
Hemorrhoids are swollen or enlarged veins and supporting tissues around the anus or in the lower rectum. They are commonly divided into two types.
| Type | Location | Common Symptoms |
|---|---|---|
| Internal hemorrhoids | Inside the lower rectum | Often painless bleeding, pressure, or tissue that protrudes during a bowel movement |
| External hemorrhoids | Under the skin around the anus | Itching, irritation, swelling, tenderness, or pain |
Hemorrhoids are not always caused by constipation. Pregnancy, chronic diarrhea, aging, frequent heavy lifting, a low-fiber diet, and prolonged toilet sitting may also increase pressure in the area.
How Does Constipation Cause Hemorrhoids?
Constipation and hemorrhoids are connected through pressure and straining.
When stool becomes hard or difficult to pass, you may hold your breath and push forcefully. This increases pressure in the veins around the anus and lower rectum. Repeating this pattern can contribute to swelling and irritation.
Constipation may also keep you sitting on the toilet longer. Even without forceful pushing, prolonged toilet sitting can add pressure to hemorrhoidal tissue.
A common cycle can develop:
- Stool becomes hard or difficult to pass.
- You strain or remain on the toilet longer.
- Hemorrhoids become swollen or irritated.
- Pain or fear of discomfort makes you delay the next bowel movement.
- The stool becomes harder, restarting the cycle.
Addressing the underlying constipation is therefore an important part of both hemorrhoid relief and prevention. Our complete constipation guide explains other common causes and gentle treatment options.
Symptoms of Hemorrhoids from Constipation
Possible symptoms include:
- A small amount of bright red blood on toilet paper, stool, or in the toilet
- Itching or irritation around the anus
- Swelling or a tender lump near the anal opening
- A feeling of pressure during or after a bowel movement
- Mild aching or discomfort while sitting
- Tissue that temporarily protrudes during a bowel movement
- Mucus or difficulty cleaning the area completely
Internal hemorrhoids commonly cause painless bleeding. External hemorrhoids are more likely to cause itching, swelling, or discomfort.
A suddenly painful, firm lump may be a thrombosed external hemorrhoid, which happens when a clot forms within an external hemorrhoid. Severe or rapidly worsening pain deserves medical assessment rather than repeated self-treatment.
Hemorrhoids vs Anal Fissure: Are They the Same?
No. An anal fissure is a small tear in the lining of the anal canal, while a hemorrhoid involves swollen vascular tissue.
Both conditions can develop after passing a hard stool, and both may cause bright red bleeding. However, an anal fissure more often causes sharp pain during a bowel movement that may continue afterward. Hemorrhoids may cause itching, swelling, pressure, painless bleeding, or a tender external lump.
Symptoms frequently overlap, so pain or bleeding alone cannot always identify the cause. See our comparison of hemorrhoids vs anal fissure for a closer look at the differences.
Can Constipation Make Hemorrhoids Bleed?
Yes. A hard stool or repeated straining may irritate hemorrhoidal tissue and cause a small amount of bright red bleeding.
However, hemorrhoids are only one possible cause of rectal bleeding. Anal fissures, inflammation, polyps, diverticular disease, and other digestive conditions can also cause blood in or around stool.
If bleeding is new, keeps returning, appears mixed throughout the stool, or comes with other changes in bowel habits, it is safer to have the cause assessed. Our guide to blood in stool explains additional patterns and warning signs.
How to Relieve Hemorrhoids Caused by Constipation
Home care has two main goals: reduce irritation around the hemorrhoid and make future bowel movements easier.
1. Focus on softer, easier-to-pass stools
High-fiber foods help stool retain water and become softer and bulkier. Useful options may include:
- Oats and other whole grains
- Beans, lentils, and peas
- Pears, berries, oranges, and prunes
- Broccoli, carrots, leafy greens, and sweet potatoes
- Chia seeds or ground flaxseed
- Nuts and seeds
Increase fiber gradually. Adding a large amount overnight may cause gas, cramping, or bloating—especially if your usual diet has been low in fiber.
Fluids help fiber work properly, but everyone’s needs differ. People with kidney disease, heart failure, or another condition requiring fluid restriction should follow their healthcare professional’s guidance.
2. Consider a fiber supplement if food is not enough
Psyllium is a bulk-forming soluble fiber that can help produce softer, more formed stools. NIDDK includes psyllium among the fiber supplements commonly used during at-home hemorrhoid care.
A fiber supplement does not directly shrink a hemorrhoid. Its role is to reduce constipation and make bowel movements less traumatic.
Start gradually and take psyllium with the amount of liquid specified on the label. Ask a pharmacist or healthcare professional before using it if you have difficulty swallowing, a known intestinal narrowing, or take medicines that may need to be separated from fiber.
If you are comparing different fiber types, read our guide to psyllium, Benefiber, and Metamucil.
3. Avoid forceful straining
Try to relax rather than holding your breath and pushing. If nothing happens after a short attempt, get up and try again later instead of remaining on the toilet.
Do not ignore the urge to have a bowel movement when a bathroom is reasonably available. Delaying repeatedly allows the colon to absorb more water from the stool, potentially making it harder.
4. Keep toilet visits brief
Scrolling on a phone can turn a short bathroom visit into a much longer one. Aim to use the toilet only for the bowel movement, then get up when you are finished.
This reduces prolonged pressure around the anus and may help prevent hemorrhoids from protruding or becoming more swollen.
5. Use a warm sitz bath
Sitting in a shallow tub of comfortably warm—not hot—water for about 10 to 20 minutes may soothe irritation and help the surrounding muscles relax. This can be repeated a few times during the day, particularly after a bowel movement if needed.
Plain warm water is usually enough. Strong soaps, fragrances, and other additives may irritate sensitive skin. Gently pat the area dry afterward rather than rubbing it.
6. Consider short-term topical relief
Over-the-counter hemorrhoid creams, ointments, or pads may temporarily relieve mild itching, swelling, or discomfort from external hemorrhoids.
These products do not correct constipation or prevent recurrence. Ingredients also vary, so follow the product label carefully. NIDDK advises following up with a doctor if an OTC hemorrhoid product does not help after one week or causes dryness, irritation, or a rash.
- For constipation support, you can check Metamucil Premium Blend on Amazon. Increase fiber gradually and take it with the liquid directed on the label.
- For mild external itching or discomfort, you can view this hemorrhoid and fissure ointment option on Amazon. Check its ingredients and directions, and do not rely on topical treatment for unexplained bleeding or severe pain.
7. Clean the area gently
Aggressive wiping can worsen irritation. Use plain, soft toilet paper or rinse gently with water when practical. If using moist wipes, choose an unscented, alcohol-free option and stop if it causes burning or irritation.
Keep the area clean and dry, but avoid excessive scrubbing or repeated use of strong soap.
What Should You Avoid During a Hemorrhoid Flare?
- Forceful or prolonged straining
- Remaining on the toilet after the bowel movement is finished
- Increasing fiber too quickly
- Repeatedly delaying the urge to pass stool
- Rubbing the irritated area aggressively
- Using multiple topical products at the same time without checking their ingredients
- Continuing an OTC hemorrhoid treatment beyond the recommended period
- Assuming every episode of rectal bleeding is caused by hemorrhoids
- Attempting to drain, cut, or otherwise remove a hemorrhoid yourself
How to Prevent Constipation-Related Hemorrhoids
Build fiber into regular meals
Consistency usually works better than suddenly eating a very high-fiber meal after several low-fiber days. Include a source of fiber at meals and increase the amount gradually according to your tolerance.
Drink enough fluid for your needs
Water and other nonalcoholic liquids can help dietary fiber work effectively. Your ideal amount depends on your health, medications, activity level, and environment.
Stay regularly active
Regular movement supports normal bowel function. Even gentle walking may be useful if prolonged sitting is part of your routine.
Create a relaxed bowel routine
The colon is often more active after meals, particularly breakfast. Giving yourself enough unhurried bathroom time may make it easier to respond to your body’s natural signals without forceful pushing.
Review possible causes of ongoing constipation
Some medicines, health conditions, dietary patterns, and pelvic floor problems can contribute to constipation. Do not stop a prescribed medicine on your own, but ask your healthcare professional whether constipation could be a side effect.
If you regularly feel that stool remains even after a bowel movement, our article about an incomplete bowel movement explains why adding more fiber is not always the complete answer.
What If Fiber Does Not Solve the Constipation?
Fiber can help many people, but constipation has several possible causes.
If stool is already soft but still feels difficult to pass, or if you regularly experience blockage, prolonged straining, or incomplete emptying, the problem may involve how the pelvic floor muscles coordinate during a bowel movement.
Other people may need a different type of laxative, a medication review, or testing for an underlying digestive condition. Persistent constipation is a reason to seek individualized guidance rather than continuously adding more supplements.
When Should You See a Doctor?
Arrange a medical appointment if:
- Rectal bleeding is new, unexplained, or keeps returning
- Symptoms do not improve after about one week of home care
- A lump or prolapsed tissue remains outside the anus
- Hemorrhoid symptoms repeatedly return
- Constipation is persistent or becoming more severe
- You develop an unexplained change in stool pattern or bowel habits
- You have unexplained weight loss, unusual fatigue, or signs of anemia
- You are unsure whether the problem is a hemorrhoid, fissure, or something else
What Medical Treatments Are Available?
If home care is not enough, a healthcare professional can confirm the diagnosis and determine whether the hemorrhoid is internal, external, prolapsed, or thrombosed.
Office-based treatments for selected internal hemorrhoids may include rubber band ligation, sclerotherapy, or infrared treatment. Large, persistent, or severely prolapsed hemorrhoids may occasionally require surgery.
The right treatment depends on the type of hemorrhoid, severity of symptoms, bleeding pattern, other health conditions, and response to conservative care. These procedures should only be performed by a qualified healthcare professional.
Frequently Asked Questions
Can constipation directly cause hemorrhoids?
Constipation can contribute to hemorrhoids through hard stools, repeated straining, and prolonged toilet sitting. It is an important risk factor, although hemorrhoids may also develop for other reasons.
Will hemorrhoids go away after constipation improves?
Mild swelling, itching, and irritation may settle after bowel movements become softer and straining stops. However, larger or prolapsed hemorrhoids may not disappear completely and sometimes require medical treatment.
How long do constipation-related hemorrhoids take to improve?
Some mild symptoms begin improving within several days, but there is no fixed timeline. Contact a healthcare professional if symptoms are not improving after about one week of appropriate home care or if bleeding or pain is worsening.
Is psyllium good for hemorrhoids?
Psyllium may help by softening and bulking stool, making it easier to pass without straining. It supports the constipation side of the problem but does not directly remove an existing hemorrhoid.
Can I use an ordinary bathtub for a sitz bath?
Yes. A separate sitz bath device is optional. A clean bathtub containing a shallow amount of comfortably warm water can provide the same basic soothing effect.
Is bright red blood always caused by hemorrhoids?
No. Hemorrhoids are a common cause, but anal fissures and other digestive conditions can produce similar bleeding. New, persistent, recurrent, or unexplained bleeding should be medically assessed.
The Bottom Line
Constipation can contribute to hemorrhoids by making stool harder to pass and increasing pressure during bowel movements.
For mild symptoms, the most useful approach is usually to soften stool, increase fiber gradually, drink an appropriate amount of fluid, avoid straining, keep toilet visits brief, and soothe irritation with warm water or short-term topical support.
Do not let embarrassment prevent you from seeking care. Rectal bleeding and anal pain have several possible causes, and a straightforward medical examination can help identify the right treatment—especially when symptoms persist or repeatedly return.
