Rectal bleeding is a symptom that should not be ignored. Very often, the cause is haemorrhoids or an anal fissure, but blood on toilet paper, in the toilet bowl or in the stool may also be a sign of conditions requiring broader diagnostics. Without an examination, it is not possible to responsibly determine the source of bleeding.
This article explains when bleeding is more likely to be related to haemorrhoids, when greater caution is needed and what proctological diagnostics look like. If you notice blood after a bowel movement, if bleeding recurs, or if it is accompanied by pain, a lump, a change in bowel habits or weakness, book a proctology consultation in Gdańsk.

Blood on toilet paper — is it always haemorrhoids?
No. Bright red blood on toilet paper, on the surface of the stool or in the toilet bowl is indeed often seen with haemorrhoids or an anal fissure. However, this does not mean that every episode of rectal bleeding can safely be assumed to be haemorrhoids.
Bleeding may come from different sites: the skin around the anus, the anal canal, the rectum, the colon and, less commonly, higher parts of the gastrointestinal tract. The colour of the blood, the timing of bleeding and accompanying symptoms are helpful in assessment, but they do not replace examination.
Patients most often search for:
- “blood on toilet paper”,
- “what does rectal bleeding mean”,
- “blood after bowel movement”,
- “bright red blood from the anus”,
- “rectal bleeding without pain”,
- “is it haemorrhoids or cancer”,
- “blood in stool when to see a doctor”.
The safest rule is simple: any new, recurrent, worsening or unexplained rectal bleeding is worth discussing with a doctor.
“Patients often assume that bright blood on toilet paper must be haemorrhoids. Very often it is, but the source of bleeding should first be confirmed. Treatment without examination may delay the correct diagnosis.”
— Sara Godyńska, MD, proctologist
The most common causes of rectal bleeding
Rectal bleeding may have many causes — from common and benign to less frequent but more serious. In practice, proctological conditions are the most common, but sometimes diagnostics of the colon are necessary.
Possible causes include:
- haemorrhoids — one of the most common causes of bright red bleeding,
- anal fissure — often causes pain and burning during bowel movements and a small amount of bright blood,
- perianal thrombosis — usually associated with pain and a lump, but may sometimes bleed,
- skin irritation around the anus,
- inflammation of the anus or rectum,
- polyps of the colon or rectum,
- inflammatory bowel disease,
- diverticular disease of the colon,
- cancerous lesions of the anus, rectum or colon,
- less commonly, other gastrointestinal diseases.
If the main symptom is bright red blood during a bowel movement, patients often suspect haemorrhoids. It is worth remembering, however, that similar symptoms may also occur in other conditions. Therefore, diagnosis should be based on examination, not only on the description of bleeding.
What does bleeding from haemorrhoids look like?
Haemorrhoids, or enlarged haemorrhoidal cushions, very often cause bright red bleeding related to bowel movements. Blood may appear on toilet paper, on the surface of the stool or in the toilet bowl.
Typical features of haemorrhoidal bleeding include:
- bright red colour of the blood,
- blood visible after a bowel movement,
- blood on toilet paper or in the toilet bowl,
- bleeding without severe pain,
- itching, burning or discomfort around the anus,
- sometimes prolapsing haemorrhoids or a feeling of incomplete bowel movement.
This is a common scenario, but not the only one. If bleeding recurs, is heavier, appears independently of stool or is accompanied by other symptoms, broader diagnostics may be necessary.

Bleeding and anal pain — what can it mean?
If bleeding is accompanied by pain, the cause may be different from typical painless bleeding from internal haemorrhoids. The character of pain matters.
The most common situations include:
- anal fissure — burning or “tearing” pain, worse during bowel movements, sometimes with bright blood on toilet paper,
- perianal thrombosis — sudden severe pain and a hard, often bluish lump near the anus,
- skin inflammation around the anus — burning, stinging, itching and irritation,
- perianal abscess — increasing, throbbing pain, swelling and sometimes fever.

Rectal bleeding — what can it suggest?
| Symptom | More common possible causes | What should you do? |
|---|---|---|
| bright blood on toilet paper after stool | haemorrhoids, anal fissure, irritation | book a consultation, especially if the symptom recurs |
| blood and pain during bowel movements | anal fissure, inflammation, thrombosis | proctological diagnostics |
| blood and a lump near the anus | haemorrhoid, perianal thrombosis, skin tag, skin lesion | examination to determine the nature of the lump |
| dark blood, clots, blood mixed with stool | possible source higher in the bowel, inflammation, polyps, other diseases | do not delay consultation and possible endoscopic diagnostics |
| bleeding with weight loss, anaemia or a change in bowel habits | requires exclusion of more serious conditions | urgent medical assessment |
When is rectal bleeding more concerning?
Every episode of bleeding is worth explaining, but some situations require particular caution. The point is not to assume the worst immediately, but to avoid delaying diagnostics.
See a doctor sooner if:
- bleeding recurs or persists despite treatment,
- the blood is dark, brownish or mixed with stool,
- the stool is black and tarry,
- bleeding appears independently of bowel movements,
- there is a change in bowel habits,
- a feeling of incomplete bowel movement appears,
- there is abdominal pain, weakness, anaemia or dizziness,
- there is unintentional weight loss,
- you feel a lump, thickening or lesion near the anus,
- the lesion bleeds, discharges, is ulcerated or does not heal,
- there is a family history of colorectal or rectal cancer,
- you are over 50 and bleeding has appeared for the first time.
In case of heavy bleeding, fainting, black stools, severe abdominal pain, high fever or rapid deterioration of general condition, urgent medical help may be needed.
Can rectal bleeding mean cancer?
It can, but most often it does not. Rectal bleeding very often results from benign conditions, especially haemorrhoids and anal fissure. The problem is that based only on the colour of blood or the description of symptoms, it is not possible to safely exclude more serious diseases.
Cancers of the anus, rectum and colon may cause bleeding, a change in bowel habits, a feeling of incomplete bowel movement, anaemia, weight loss, pain or the presence of a lump. Such symptoms do not equal a diagnosis of cancer, but they are a reason for diagnostics.
If the patient’s main fear is “is it haemorrhoids or cancer?”, it is also worth reading: is it haemorrhoids or anal cancer?
“Rectal bleeding often has a benign cause, but it should not be diagnosed online. First, we need to determine exactly where the blood is coming from and whether proctological treatment is enough or broader diagnostics are needed.”
— Justyna Szul, MD, proctologist
What does diagnostics of rectal bleeding look like?
Diagnostics begins with a proctology consultation. The doctor asks about the colour of the blood, the moment bleeding appears, pain, a lump, itching, bowel movements, constipation, diarrhoea, medications, chronic diseases and family history.
The examination may include:
- inspection of the anal area,
- palpation,
- digital rectal examination, if indicated and possible,
- anoscopy,
- discussion whether further tests are needed, such as rectoscopy, colonoscopy, laboratory tests or imaging.
The scope of diagnostics depends on symptoms, the patient’s age, risk factors, examination findings and the character of bleeding. In some patients, proctological diagnostics is sufficient, while in others the doctor may recommend a more complete assessment of the colon.
Anoscopy — why is it important in bleeding?
Anoscopy is a short examination that allows the doctor to view the anal canal and the final part of the rectum. It is particularly useful when the doctor suspects the source of bleeding is in the anal area.
Anoscopy may help diagnose, among others:
- haemorrhoids,
- anal fissure,
- inflammation of the anal canal,
- the source of discharge or irritation,
- some mucocutaneous lesions,
- lesions requiring further diagnostics.
Important: anoscopy does not replace colonoscopy if symptoms suggest a possible source of bleeding higher in the colon. That is why the doctor selects tests individually.
Does anoscopy hurt?
Anoscopy is a short examination and is usually well tolerated. It may cause a feeling of pressure or discomfort, but it should not be a very painful examination. If the patient has severe pain, a fissure, thrombosis or inflammation, the doctor adjusts the scope of examination to the situation.
The most important thing is for the patient to tell the doctor about pain and concerns. The examination is performed with respect for the patient’s intimacy and comfort.
When should you see a proctologist?
It is worth seeing a proctologist for any new, recurrent or unexplained rectal bleeding. You do not need to wait until symptoms worsen. Early consultation often helps quickly identify the cause and choose the right treatment.
Book a visit if:
- you see blood on toilet paper,
- blood appears in the toilet bowl,
- bleeding occurs during a bowel movement,
- bleeding recurs,
- it is accompanied by pain, itching, burning or a lump,
- constipation or diarrhoea occurs,
- your bowel habits have changed,
- you are worried whether it is haemorrhoids or something more serious.

Frequently asked questions
Is blood on toilet paper always haemorrhoids?
No. Blood on toilet paper often occurs with haemorrhoids or an anal fissure, but it may have other causes as well. If bleeding is new, recurrent or worrying, it is worth discussing it with a doctor.
Is rectal bleeding dangerous?
Not always. Benign conditions are often the cause, but bleeding should not be ignored because it may sometimes require broader diagnostics, especially if it recurs or is accompanied by other symptoms.
What test detects the cause of rectal bleeding?
The basis is a proctology consultation, examination of the anal area and often anoscopy. In some patients, the doctor may also recommend rectoscopy, colonoscopy, laboratory tests or other examinations.
Does anoscopy hurt?
Anoscopy is short and usually well tolerated. It may cause pressure or discomfort. If the patient has severe pain, the doctor adjusts the scope of examination to the situation.
Does bright red blood mean haemorrhoids?
Bright red blood often comes from the lower gastrointestinal tract, including the anal area, and may occur with haemorrhoids. However, this is not a certain diagnosis. Recurrent bleeding requires assessment.
When does rectal bleeding require urgent help?
Urgent help may be needed with heavy bleeding, black stools, fainting, severe abdominal pain, high fever, dizziness or rapid deterioration of general condition.
Which proctologist should I see in Gdańsk?
At Wyspa Medycyny Przyjaznej, consultations are provided by Sara Godyńska, MD, Justyna Szul, MD and Dr Kamil Smok. You can start with a proctology consultation in Gdańsk.
Do you notice blood on toilet paper or in the toilet?
Do not assume it is definitely haemorrhoids. A proctologist will assess the source of bleeding and decide whether proctological treatment is enough or further diagnostics are needed.
Book a proctology consultation →Summary
Rectal bleeding most often results from benign conditions such as haemorrhoids or anal fissure, but it should not be ignored. Blood on toilet paper, blood in the toilet bowl or blood in the stool requires assessment, especially if the symptom recurs, worsens or is accompanied by pain, a lump, a change in bowel habits, anaemia, weakness or weight loss.
The basis of diagnostics is a proctology consultation. In many patients, anoscopy is helpful because it allows assessment of the anal canal and possible sources of bleeding in this area. In some patients, the doctor may recommend further tests, including colon diagnostics.
If you notice rectal bleeding, book a proctology consultation in Gdańsk. Early assessment helps determine the cause and choose the right management.
