Anal itching is a common, embarrassing and very uncomfortable symptom. It may be caused by skin irritation, moisture, excessive hygiene, haemorrhoids, anal skin tags, anal fissure, fungal infection, bacteria, parasites, allergy, skin diseases or other proctological conditions. Treatment depends on the cause — so chronic or recurrent itching should not be treated “blindly”.
This article explains where anal itching may come from, when the problem requires diagnostics, what a proctological examination looks like and how to break the vicious cycle of itching, scratching and irritation. If itching lasts longer, comes back, worsens or is accompanied by pain, bleeding, a lump, discharge or rash, book a proctology consultation in Gdańsk.

Anal itching — a symptom, not one specific disease
Anal itching, also called pruritus ani, means persistent itching of the skin around the anus. It may be mild and occasional, but in some patients it becomes chronic, worsens at night, after bowel movements, after sweating, after alcohol, after spicy food or after using certain cosmetics.
The most important thing is that itching is not a diagnosis in itself. It is a symptom that may have many causes. In one patient, correcting hygiene and reducing irritation may be enough. In another, haemorrhoids need to be treated. In another, the cause may be a fungal infection, a skin disease, parasites or discharge that irritates the skin.
The most common questions patients ask are:
- “anal itching — what does it mean?”,
- “why does my anus itch?”,
- “how to get rid of anal itching?”,
- “is anal itching caused by haemorrhoids?”,
- “can anal itching mean a fungal infection or parasites?”.
The answer depends on the examination and on what the doctor sees on the skin, in the anal canal and in the medical history.
The vicious cycle of itching: itching, scratching, irritation
Anal itching can easily turn into a vicious cycle. The skin around the anus is delicate and often exposed to moisture, sweat, stool residue, underwear friction and cosmetics. When it starts to itch, the patient scratches the area or washes it very intensively. This may bring temporary relief, but it damages the skin barrier and may worsen the problem.
The vicious cycle may look like this:
- itching leads to scratching,
- scratching damages the epidermis,
- damaged skin burns and itches even more,
- the patient washes the anal area more often and uses soaps, wipes or cleansing liquids,
- cosmetics and moisture irritate the skin further,
- itching comes back even stronger.
That is why treatment is not just about “applying any ointment”. Often, the most important steps are stopping irritation, keeping the skin dry, ruling out a proctological condition and choosing treatment according to the cause.
“With anal itching, we often see not one cause, but several overlapping factors: moisture, scratching, cosmetics, haemorrhoids, anal skin tags or infection. That is why we first need to identify what is driving the symptoms.”
— Sara Godyńska, MD, proctologist
The most common causes of anal itching
The causes of anal itching can be divided into several groups: proctological, skin-related, infectious, hygiene-related, dietary and systemic. More than one factor is often present in the same patient.
1. Haemorrhoids
Haemorrhoids may cause itching, especially when they are accompanied by discharge, moisture, soiling of underwear, inflammation or difficulty maintaining proper hygiene. Itching may occur together with bleeding, prolapse, burning or discomfort.

2. Anal skin tags
Anal skin tags may make hygiene around the anus more difficult, retain moisture and discharge residue, and therefore promote skin irritation. In some patients, they are only an aesthetic issue, but in others they may be associated with itching, burning, skin maceration or a feeling of soiling.

3. Anal fissure
An anal fissure is more often associated with sharp pain during bowel movements and bright red blood, but it may also cause burning, irritation and itching. In chronic fissures, a sentinel skin tag, inflammation and skin sensitivity may appear.

4. Fungal infections
A fungal infection around the anus may cause severe itching, burning, redness, moist skin, small cracks or rash. It is more common with moisture, sweating, antibiotic therapy, diabetes, reduced immunity or chronic skin irritation.
In such a situation, a random “anti-itch” ointment may not be enough. Skin assessment may be needed, sometimes with mycological testing or antifungal treatment selected by a doctor.
5. Bacterial infections and skin inflammation
The anal area may become secondarily infected with bacteria, especially when the skin has been damaged by scratching, moisture or long-term use of irritating products. Symptoms may include redness, burning, soreness, discharge, skin cracks or an unpleasant smell.
If purulent discharge, increasing pain, swelling or fever appears, a perianal abscess must be ruled out. More: perianal abscess — symptoms and urgent consultation.
6. Parasites, including pinworms
Anal itching that worsens in the evening or at night may be associated with pinworm infection, especially in children, but adults in the same household may also be affected. In such cases, the doctor may recommend appropriate diagnostics or antiparasitic treatment for the patient and sometimes also for close contacts.
Not every night-time itching means parasites, but with typical symptoms it is worth considering them in diagnostics.
7. Allergy and contact dermatitis
The skin around the anus may react to cosmetics, toilet paper, wet wipes, intimate hygiene liquids, scented liners, laundry detergents, latex, ointments, suppositories or preparations used “for haemorrhoids”. Paradoxically, the more products a patient uses, the greater the risk of irritation or contact allergy.
In diagnostics, it is important to ask not only about diseases, but also about what the patient uses to wash, apply to and wipe the anal area.
8. Excessive or insufficient hygiene
Too little hygiene may promote irritation from stool residue and moisture. On the other hand, excessive hygiene — frequent washing, strong rubbing, soaps, antibacterial gels, scented wipes — may damage the natural skin barrier and worsen itching.
Most often, gentle hygiene with water, avoiding scented products and careful but gentle drying of the skin works best.
9. Diet, alcohol, coffee and diarrhoea
In some patients, itching worsens after alcohol, coffee, spicy food, citrus fruit, tomatoes, chocolate or products that loosen stools. This does not mean that everyone has to eliminate these products permanently. However, it is worth observing whether symptoms correlate with diet.
Itching may also worsen with diarrhoea, frequent bowel movements, gas incontinence or minor leakage of stool.
10. Skin diseases and systemic diseases
Itching around the anus may be part of dermatological conditions such as eczema, psoriasis, lichen sclerosus, lichen planus or atopic dermatitis. It may also be more common in diabetes, liver disease, kidney disease, immune disorders or chronic diarrhoea.
That is why recurrent, difficult-to-treat itching may sometimes require cooperation between a proctologist, dermatologist, family doctor or gastroenterologist.
Anal itching and haemorrhoids — when should haemorrhoidal disease be suspected?
Haemorrhoids are a common cause of itching, but not every person with anal itching has haemorrhoids. Haemorrhoidal disease is more likely if itching is accompanied by:
- bright red blood during bowel movements,
- prolapse of haemorrhoidal cushions,
- a feeling of moisture or discharge,
- soiling of underwear,
- a feeling of obstruction in the anus,
- itching worsening after bowel movements,
- constipation, strong straining or long toilet sitting.
In some patients, treating only the itching is not enough if the cause is discharge and irritation related to haemorrhoids. In that case, cause-directed treatment is needed after examination.

Anal skin tags and itching — why can the skin become irritated?
Anal skin tags are excess folds of skin around the anus. They may remain after perianal thrombosis, inflammation, pregnancy, childbirth, anal fissure or recurrent proctological problems. They do not always require treatment.
The problem appears when skin tags:
- make hygiene difficult,
- retain moisture,
- cause skin maceration,
- promote irritation after bowel movements,
- cause a feeling of soiling or discomfort,
- are repeatedly irritated during wiping.
In selected patients, if skin tags are truly causing symptoms, procedural treatment may be considered. However, the decision requires examination, because itching alone does not automatically mean that skin tags need to be removed.
What does diagnostics of anal itching involve?
Diagnostics begin with a conversation. The doctor needs to know when the itching started, whether it worsens at night, after bowel movements, after alcohol, after certain foods, after physical activity, after antibiotics or after using specific cosmetics. Bleeding, pain, a lump, discharge, diarrhoea, constipation, medications, skin diseases and chronic conditions are also important.
The consultation may include:
- Medical history — duration of symptoms, hygiene, diet, cosmetics, medications, diseases, bowel movements.
- Inspection of the skin around the anus — assessment of redness, maceration, cracks, erosions, rash, skin tags and discharge.
- Digital rectal examination — if indicated and possible.
- Anoscopy — allows assessment of the anal canal, haemorrhoids, fissure, inflammation or other lesions.
- Additional tests — if indicated, for example swab, mycological testing, parasite diagnostics, blood tests, dermatology or gastroenterology consultation.
More about the examination: anoscopy — proctological examination.
Anal itching — what may suggest the cause?
| Accompanying symptom | Possible diagnostic direction |
|---|---|
| Bleeding during bowel movements | haemorrhoids, fissure, polyp, inflammation or another cause of bleeding |
| Severe pain and a lump | perianal thrombosis, perianal abscess, inflammatory flare-up |
| Moisture, discharge, soiling of underwear | haemorrhoids, anal skin tags, fistula, leakage, inflammation |
| Worsening at night | parasites, skin irritation, skin diseases, vicious cycle of scratching |
| Redness, rash, skin cracks | fungal infection, contact allergy, eczema, psoriasis, secondary infection |
| Recurrence after antibiotics | possible fungal infection or disruption of the skin and gut microbiome |
Can anal itching mean something serious?
Most often, anal itching is caused by benign problems: irritation, moisture, haemorrhoids, skin tags, infection or skin diseases. However, not every case of itching should be assumed to be harmless, especially if additional symptoms appear.
Consultation is needed if itching is accompanied by:
- rectal bleeding,
- severe or increasing pain,
- a lump near the anus,
- purulent discharge,
- ulceration, a non-healing wound or an unusual skin lesion,
- weight loss, anaemia or weakness,
- change in bowel habits,
- fever or rapidly increasing swelling.

Treatment of anal itching — first, the cause
Treatment of anal itching should be cause-directed. Haemorrhoids, fungal infection, contact allergy, parasites and irritation caused by excessive hygiene are treated differently.
Cause-directed treatment may include:
- treatment of haemorrhoids if they are causing discharge, moisture and irritation,
- treatment of an anal fissure if itching is accompanied by pain and a mucosal tear,
- treatment of fungal, bacterial or parasitic infection,
- treatment of skin diseases such as eczema, psoriasis or lichen,
- limiting allergenic cosmetics and topical preparations,
- treatment of diarrhoea, constipation, discharge or incontinence,
- considering treatment of anal skin tags if they are truly driving symptoms,
- diagnostics for fistula or abscess if discharge, pain or swelling is present.
Symptomatic treatment and care may include:
- gentle hygiene with water, without intense rubbing,
- avoiding scented wipes, soaps and irritating cleansing liquids,
- careful, gentle drying of the skin,
- wearing breathable underwear,
- reducing moisture and sweating,
- barrier preparations, for example with zinc oxide, if the doctor considers this appropriate,
- short-term use of anti-inflammatory or anti-itch medicines only as recommended by a doctor,
- avoiding long-term self-use of steroids without medical supervision.
Note: long-term use of random ointments, especially steroid, antibiotic or combined “for everything” preparations, may worsen the problem, mask symptoms or cause additional irritation.
Hygiene with anal itching — what should be avoided?
When anal itching occurs, patients often begin washing the anal area more frequently and with stronger products. This is understandable, but it may have the opposite effect. Excessive washing removes the natural protective layer of the skin and may worsen burning.
It is worth avoiding:
- scented wet wipes,
- strong soaps and antibacterial gels,
- intense rubbing with toilet paper,
- scratching, including through underwear,
- leaving moisture after washing,
- using many ointments at the same time without medical advice,
- tight, non-breathable underwear,
- ignoring diarrhoea or soiling of underwear.
Simple care is usually safer: water, gentle drying and avoiding irritating products. If the skin is very irritated, the choice of a protective preparation should be discussed with a doctor.
When should you see a proctologist?
Consultation is recommended if itching lasts longer, comes back, worsens or does not improve despite hygiene changes. It is especially important not to delay if additional symptoms appear.
Book a visit if:
- itching lasts longer than a few weeks,
- the problem recurs despite ointments or hygiene changes,
- itching wakes you at night,
- bleeding, pain or a lump is present,
- discharge, moisture or underwear soiling occurs,
- you notice redness, a wound, cracks or rash,
- you suspect fungal infection, parasites or allergy,
- you have diabetes, reduced immunity, inflammatory bowel disease or chronic diarrhoea.
Early diagnostics help avoid long-term use of random preparations and allow treatment to be matched to the real cause of itching.

Frequently asked questions
Does anal itching mean haemorrhoids?
Not always. Haemorrhoids may cause itching, especially when moisture, discharge or prolapse is present, but itching may also result from infection, allergy, anal skin tags, fissure, parasites or skin diseases.
Can anal itching be caused by a fungal infection?
Yes. A fungal infection may cause itching, redness, burning, moisture, skin cracks or rash. It is more common with moisture, antibiotic therapy, diabetes or reduced immunity.
Can parasites cause anal itching?
Yes, especially pinworms may cause itching that worsens in the evening or at night. Not every night-time itching means parasites, but with typical symptoms they should be considered in diagnostics.
What does diagnostics of anal itching involve?
Diagnostics include medical history, assessment of the skin around the anus, proctological examination, sometimes anoscopy, and — if indicated — additional tests such as a swab, mycological testing, parasite diagnostics or dermatology consultation.
What should be avoided with anal itching?
It is worth avoiding scratching, scented wipes, strong soaps, intense rubbing with toilet paper, moisture, tight underwear and long-term self-use of random ointments, especially steroid-based ones.
When does anal itching require consultation?
Consultation is needed if itching is chronic, recurrent, worsening, wakes the patient at night or is accompanied by pain, bleeding, a lump, discharge, rash, purulent fluid or a change in bowel habits.
Anal itching keeps coming back despite ointments and hygiene changes?
Do not treat the symptom blindly. A proctologist can help determine whether the cause is haemorrhoids, skin tags, infection, allergy, fissure, skin disease or another problem.
Book a proctology consultation →Summary
Anal itching is a symptom that may have many causes. It may result from haemorrhoids, anal skin tags, anal fissure, fungal infection, bacteria, parasites, allergy, skin diseases, moisture, diarrhoea, constipation or excessive hygiene.
The most important step is finding the cause. Without diagnostics, patients often use more and more ointments that temporarily relieve the symptom but do not solve the problem — or additionally irritate the skin.
If itching lasts longer, comes back, worsens or is accompanied by pain, bleeding, a lump, discharge or rash, it is worth booking a proctology consultation.
