What Are Hemorrhoids? Your Complete 2026 Guide
Hemorrhoids, also known as piles, are swollen and inflamed veins in the lower rectum and anus. They're one of the most common medical conditions worldwide — affecting an estimated 75% of adults at some point in their lives.
Despite how common they are, many people suffer in silence due to embarrassment. But here's the truth: hemorrhoids are not a sign of poor hygiene or moral failure — they're a normal anatomical response to pressure.
This guide will explain:
- What hemorrhoids really are (anatomy included)
- The 3 main types — and how to tell them apart
- What causes them (it's not just toilet habits)
- What a hemorrhoid feels like and looks like
- How to know if you actually have one
- Who's at risk — and why
- How to know if it's hemorrhoids or something more serious
- Prevention and when to see a doctor
Anatomy: Where Hemorrhoids Form
Your body has a network of blood vessels around the anus and lower rectum called "hemorrhoidal plexus." These vessels help with stool control and cushioning during bowel movements.
When pressure increases — from straining, pregnancy, or prolonged sitting — these veins can stretch, bulge, or swell. That's when they become "hemorrhoids."
📍 Internal hemorrhoids: Form above the dentate line (inside the rectum) — usually painless.
📍 External hemorrhoids: Form below the dentate line (under the skin) — often painful.
📍 Thrombosed hemorrhoids: A blood clot forms inside — sudden, severe pain.
📌 Note: Everyone has hemorrhoidal tissue — it only becomes a "hemorrhoid" when it's swollen or symptomatic.
The 3 Types of Hemorrhoids (With Symptoms)
1. Internal Hemorrhoids
Located inside the rectum. Often painless because there are few pain-sensing nerves here.
Symptoms:
- Bright red blood on toilet paper or in the bowl
- Prolapse (tissue that bulges out during bowel movements — may retract on its own or need to be pushed back)
- Feeling of fullness or pressure
Grading (Goligher System):
- Grade I: No prolapse — just bleeding
- Grade II: Prolapses during straining, but retracts on its own
- Grade III: Prolapses and must be pushed back manually
- Grade IV: Permanently prolapsed — cannot be pushed back
2. External Hemorrhoids
Located under the skin around the anus. Painful because this area is rich in nerve endings.
Symptoms:
- Pain or discomfort, especially when sitting
- Itching or irritation
- Swelling or lump near the anus
- Bleeding (less common than internal)
3. Thrombosed Hemorrhoids
A blood clot forms inside an external hemorrhoid. This is the most painful type.
Symptoms:
- Sudden, severe pain
- Hard, bluish lump near the anus
- Swelling and inflammation
- May rupture and bleed
🚨 Seek immediate care if: You have severe pain + a hard lump — it may need drainage. Don't try to pop it yourself.

What Does a Hemorrhoid Feel Like?
The sensation depends on the type — internal and external hemorrhoids feel very different.
Internal hemorrhoids
Internal hemorrhoids form inside the rectum where there are almost no pain receptors, so they're often completely painless. Most people don't know they have one until they notice:
- A streak of bright red blood on toilet paper or in the bowl after a bowel movement
- A vague feeling of pressure or fullness in the rectum, as if the bowel movement wasn't complete
- In more advanced cases (Grade II–IV), tissue that protrudes out of the anus during straining — this can feel like a soft, wet bulge that may or may not go back in on its own
External hemorrhoids
External hemorrhoids sit under the sensitive skin around the anus, where nerve endings are dense. They tend to cause a cluster of sensations:
- Aching or throbbing pain, especially when sitting, walking, or after a bowel movement
- Itching or burning around the anus — often worse after bowel movements or at night
- A tender lump or swelling you can feel when wiping or touching the area
- A sensation of something being in the way when sitting

Thrombosed hemorrhoids
A thrombosed hemorrhoid — where a blood clot forms inside — produces the most distinctive feeling:
- Sudden, intense pain that comes on within minutes to hours, often described as sharp, stabbing, or constant pressure
- A hard, firm lump near the anus that is exquisitely tender to touch
- The pain typically peaks within 48–72 hours and then gradually subsides as the clot is reabsorbed
📌 Key distinction: Painless bleeding = likely internal. Painful lump = likely external or thrombosed. Both at once? Could be mixed hemorrhoids — see a doctor.

What Does a Hemorrhoid Look Like?
What you can actually see depends on which type you have.
Internal hemorrhoids
You typically cannot see an internal hemorrhoid — it's inside the rectum. The only visible sign is bright red blood on toilet paper, in the bowl, or coating the stool. The blood is usually fresh and bright (not dark or mixed into the stool).
In Grade III or IV cases, the hemorrhoid may prolapse (slip out of the anus). A prolapsed internal hemorrhoid looks like a soft, moist, pink or reddish lump of tissue protruding from the anus. It may resemble a small grape or a swollen piece of tissue.
External hemorrhoids
External hemorrhoids are visible around the outside of the anus. They appear as:
- A soft, skin-colored or slightly reddened swelling around the anal opening — may be barely noticeable when mild
- A firm, round lump that can range in size from a pea to a grape
- Multiple small bumps clustered around the anus in chronic cases
When an external hemorrhoid becomes thrombosed, it looks distinctly different: a hard, dark bluish-purple lump, often tense and shiny from swelling. It can appear suddenly and looks alarming — but while painful, it is rarely dangerous.
Hemorrhoid skin tags
After an external hemorrhoid heals, it sometimes leaves behind a skin tag — a small, soft flap of excess skin near the anus. These are painless but can be mistaken for an active hemorrhoid. They don't require treatment unless they cause hygiene issues or discomfort.
→ Learn how to address skin tags in our Home Remedies Guide.
🚨 When the appearance is a red flag: Dark red or black blood, a lump that is growing, or bleeding that won't stop — these are not typical hemorrhoid signs. See a doctor to rule out other conditions.
How Do You Get a Hemorrhoid?
Hemorrhoids develop when increased pressure causes the veins in the anal and rectal area to swell. This can happen gradually over time or be triggered by a specific event. The most common causes:
Straining during bowel movements
The single most common cause. When you push hard to pass a stool — whether from constipation or simply spending too long on the toilet — pressure builds in the lower rectum and forces the hemorrhoidal veins to expand. Even one episode of severe straining can trigger a hemorrhoid, but chronic straining is the bigger risk.
Low-fiber diet and dehydration
Hard, dry stools require more effort to pass, which means more straining. A diet low in fiber (less than 15–20g/day for most adults) and insufficient water intake are the root cause of most constipation-driven hemorrhoids.
Pregnancy
One of the most common times for hemorrhoids to first appear. The growing uterus puts direct pressure on the rectal veins, progesterone relaxes the walls of blood vessels making them more prone to swelling, and constipation — common in pregnancy — compounds the problem. Postpartum straining during labor is another trigger.
Prolonged sitting
Spending long periods sitting — especially on the toilet — increases pressure in the anal region. Office workers, drivers, and anyone with a sedentary lifestyle face higher risk. The seated position on a toilet is particularly problematic because it leaves the anal area unsupported and under continuous pressure.
Chronic diarrhea
Frequent loose bowel movements irritate and inflame the anal tissue, and the repeated physical effort of multiple daily bowel movements can strain the veins even without hard stools.
Heavy lifting
Lifting heavy objects without proper technique causes a spike in intra-abdominal pressure — the same mechanism as straining on the toilet. Weightlifters and manual laborers are at higher risk, especially if they hold their breath while lifting (the Valsalva maneuver).
Age
After 45, the connective tissue that holds hemorrhoidal veins in place begins to weaken and stretch. This is why hemorrhoids become more common with age — even without other risk factors.
Genetics
Some people inherit naturally weaker vein walls or connective tissue, making them more susceptible regardless of lifestyle. If your parents had hemorrhoids, your risk is higher.
📌 Myth Buster: Spicy food does NOT cause hemorrhoids — but it can irritate existing ones. The same goes for alcohol: not a cause, but a trigger for flares.
How Do You Know If You Have a Hemorrhoid?
There's no single definitive sign — hemorrhoids can present differently depending on their type and severity. Here's how to tell:
Signs that strongly suggest hemorrhoids
Bright red blood after a bowel movement is the most common first sign of an internal hemorrhoid. The key word is bright — the blood is fresh, typically seen on the toilet paper or coating the stool, not mixed darkly into it.
A painful lump near the anus that appeared suddenly, especially after a period of straining or constipation, is the hallmark of an external or thrombosed hemorrhoid.
Itching or moisture around the anus that gets worse after bowel movements often indicates an external hemorrhoid or a prolapsed internal one leaking mucus.
A feeling that your bowel movement was incomplete, or a sense of fullness even after going, can be caused by an internal hemorrhoid sitting at the rectal opening.
How to do a basic self-check
You can feel for external hemorrhoids yourself using clean hands and a mirror:
- Wash hands thoroughly
- Use a handheld mirror or position yourself to see the anal area in a bathroom mirror
- Look for any lumps, bumps, or swelling around the anus
- Gently feel the area — external hemorrhoids feel like soft or firm bumps under the skin
Internal hemorrhoids cannot be felt from the outside and require a doctor to diagnose properly (via digital rectal exam or anoscopy).
When it's probably not a hemorrhoid
Some signs point toward other conditions that need medical attention:
- Dark red or black stool → possible upper GI bleed (not hemorrhoids)
- Sharp, knife-like pain during bowel movements → more likely an anal fissure
- Pus or discharge → possible abscess or fistula
- Bleeding + unexplained weight loss → requires colonoscopy to rule out cancer
🚨 Rule of thumb: If you're over 45 and experiencing new rectal bleeding for the first time — even if it looks like a typical hemorrhoid — see a doctor. Colorectal cancer can mimic hemorrhoid symptoms and is highly treatable when caught early.

What Causes Hemorrhoids? (It's Not Just Toilet Time)
Many people think hemorrhoids are caused by sitting too long on the toilet — and while that can contribute, it's rarely the only cause. See the full breakdown in the How Do You Get a Hemorrhoid section above. For a full breakdown of every cause and its mechanism, see What Causes Hemorrhoids
Who Gets Hemorrhoids? (Risk Factors)
Hemorrhoids can affect anyone — but some groups are at higher risk:
| Group | Why |
|---|---|
| Pregnant women | Uterine pressure + progesterone relaxing veins |
| Adults 45–65 | Weaker supportive tissues |
| Office workers / drivers | Prolonged sitting |
| Weightlifters / laborers | Frequent straining |
| People with chronic constipation | Straining damages veins |
| Those with low-fiber diets | Hard stools → straining |
Hemorrhoids vs. Other Conditions
Rectal bleeding or pain doesn't always mean hemorrhoids. It could be:
- Anal fissure — a small tear in the lining (sharp pain during bowel movements)
- Anal fistula — an infected tunnel from the anus to the skin (pus, swelling)
- Colorectal cancer — persistent bleeding, weight loss, change in bowel habits
- Proctitis — inflammation of the rectum (often from IBD or infection)
🚨 Red Flags — See a Doctor Immediately If You Have:
- Dark red or black stool (may indicate upper GI bleed)
- Unexplained weight loss
- Persistent bleeding for >1 week
- Lump that doesn't go away
- Family history of colorectal cancer
Can Hemorrhoids Go Away on Their Own?
Yes — mild hemorrhoids often resolve within a few days to a week with:
- Increased fiber and water intake
- Sitz baths
- OTC creams or suppositories
- Avoiding straining
But: If they're Grade III/IV or thrombosed — they may need medical intervention.
✅ Tip: Start with conservative treatment for 7 days. If no improvement — consult a doctor.
→ See our How Long Does a Hemorrhoid Last guide for a full timeline by type and severity.
Prevention: How to Avoid Hemorrhoids
You can't always prevent them — but you can drastically reduce your risk:
- Eat 25–35g of fiber daily (fruits, veggies, whole grains, psyllium)
- Drink 8+ glasses of water (softens stool)
- Don't delay bowel movements (ignoring urges leads to harder stool)
- Avoid straining (if it doesn't come easily, get up and try later)
- Exercise regularly (even walking 30 min/day helps)
- Avoid prolonged sitting (get up every 30–60 min)
- Use a footstool (squatting position reduces straining)
When to See a Doctor
Don't suffer in silence. See a healthcare provider if:
- Bleeding lasts more than a week
- Pain interferes with daily life
- You feel a lump that won't go away
- You're over 45 and have new rectal bleeding (to rule out cancer)
- Home treatments aren't working
💡 Pro tip: Ask for a proctologist or colorectal surgeon — they specialize in this area.
FAQs About Hemorrhoids
Are hemorrhoids contagious?
No. Hemorrhoids are swollen blood vessels — not caused by viruses or bacteria. You cannot catch them from toilet seats, towels, or other people.
Can hemorrhoids turn into cancer?
No — hemorrhoids do not become cancerous. However, rectal bleeding can be a symptom of colorectal cancer. Never ignore persistent bleeding, especially if you're over 45 or have a family history.
Can you pop a hemorrhoid?
No — and you should never try. Popping can cause infection, severe bleeding, or scarring. Thrombosed hemorrhoids should be drained by a doctor in sterile conditions.
Do only older people get hemorrhoids?
No — while more common after 45, young adults and even teenagers can get them, especially with constipation, pregnancy, or heavy lifting.
Can stress cause hemorrhoids?
Indirectly — stress can lead to constipation or diarrhea, which can trigger hemorrhoids. Stress also causes muscle tension, including in the pelvic floor.
Are hemorrhoids dangerous?
Rarely. Most are harmless and resolve on their own. But severe bleeding can lead to anemia, and thrombosed hemorrhoids can cause intense pain requiring urgent care.
Can I exercise with hemorrhoids?
Yes — walking, swimming, and yoga are great. Avoid heavy lifting or cycling (pressure on the area) until symptoms improve.
What does a hemorrhoid feel like for the first time?
First-timers often notice either painless bright red blood (internal) or a sudden painful lump near the anus (external). Many people mistake early hemorrhoids for a pulled muscle or skin irritation. If you notice blood or a lump — even without pain — it's worth checking.
Can I have hemorrhoids without knowing it?
Yes — internal hemorrhoids are often completely painless and many people have them without realizing it until they spot blood. A routine rectal exam or colonoscopy sometimes reveals them incidentally.
Key Takeaways
- Hemorrhoids are swollen veins — not a moral failing or hygiene issue.
- There are 3 types: internal (painless, bleeding), external (painful, lump), thrombosed (clot, severe pain).
- Internal hemorrhoids feel like pressure or fullness and cause bright red bleeding — you can't see or feel them from outside.
- External hemorrhoids look and feel like a soft or firm lump near the anus; thrombosed ones are hard, bluish, and intensely painful.
- Causes include straining, pregnancy, sitting, low fiber — not just "bad habits."
- You can often self-identify hemorrhoids by symptoms, but a doctor is needed to rule out other conditions — especially if you're over 45.
- Prevention is possible with diet, hydration, and movement.
- Most resolve at home — but know when to seek help.
