Anal Warts (Anogenital Warts): Symptoms, Causes and Treatment in the UK

Anal warts, medically known as condyloma acuminata, are small growths that appear around or inside the anus. They are a subset of anogenital warts and are one of the most common sexually transmitted infections (STIs) in the United Kingdom. These growths are caused by the Human Papillomavirus (HPV), specifically types 6 and 11, which are low-risk strains that do not typically lead to cancer.

Unlike other digestive concerns like haemorrhoids (piles) or anal fissures, warts are viral in origin. They may appear as single tiny spots or in clusters that resemble a small cauliflower. While they are often painless, they can cause significant distress and discomfort for patients due to their location and the stigma surrounding STIs.

Many people with anal warts do not experience any physical pain, which is why they may go unnoticed for some time. However, when symptoms do occur, they typically include:

• Small bumps: Flesh-coloured, brownish, or pinkish growths that can be flat or raised.
• Texture: Some warts are smooth, but many develop a rough, cauliflower-like surface.
• Itching: A persistent itch (pruritus ani) in the perianal region.
• Bleeding or discharge: Occasionally, warts may bleed during bowel movements or cause unusual moisture in the area.
• Sensation of a lump: Feeling like there is something 'extra' near the anus when wiping.

According to NHS guidelines, it is essential to have any new lump in the anal area checked by a healthcare professional, as self-diagnosis can lead to confusion with other conditions like perianal skin tags or molluscum contagiosum.

The Human Papillomavirus is highly contagious and is passed through skin-to-skin contact. While anal warts are frequently associated with receptive anal intercourse, they can also be spread through:

• Hand-to-genital contact.
• Genital-to-genital rubbing.
• Sharing sex toys that have not been properly cleaned or covered.

It is important to note that the virus can remain dormant in the skin for weeks, months, or even years before a wart appears. This means you or a partner might have the virus without knowing it. In the UK, the HPV vaccination programme in schools has significantly reduced the prevalence of these warts in younger generations, but many adults remains susceptible to the low-risk strains that cause them.

Many patients initially contact an online doctor in the UK believing they have haemorrhoids (piles). While both can cause lumps around the anus, there are key differences:

Haemorrhoids

Haemorrhoids are swollen blood vessels. They often feel soft, can be very painful or tender, and frequently cause bright red blood on the toilet paper. They may 'pop out' during straining and can often be pushed back in.

Anal Warts

Warts are skin growths. They are rarely 'squishy' like a blood vessel and usually have a firmer, grittier texture. They do not typically change size based on bowel movements and are almost never painful unless they become irritated or infected.

Following NICE (National Institute for Health and Care Excellence) guidance, the choice of treatment depends on the size, location, and number of warts. Treatment aims to remove the visible warts, though it may not completely clear the underlying HPV virus from the skin.

• Topical Creams and Liquids: For warts on the external skin, creams like podophyllotoxin or imiquimod are often prescribed. These are applied by the patient at home over several weeks to chemically erode the wart or stimulate the immune system to attack the virus.
• Cryotherapy: A GP or specialist may use liquid nitrogen to freeze the warts, causing them to fall off. This usually requires multiple sessions.
• Excision or Cautery: For larger or internal warts, a minor surgical procedure under local anaesthetic may be required to cut the warts away or burn them off using heat (electrocautery).
• Laser Treatment: Occasionally used for extensive cases that haven't responded to other methods.

If you have noticed new lumps or skin changes around your anus, speaking to a GP is the first step toward relief. Many patients feel embarrassed, but clinicians deal with anogenital health daily and provide a calm, non-judgemental environment. You should seek a consultation if:

• You have found a new growth and are unsure what it is.
• Over-the-counter haemorrhoid treatments are not working.
• You are experiencing persistent itching or discomfort.
• You have a partner who has been diagnosed with genital warts.

An online doctor in the UK can provide a discrete initial assessment. You may be asked to provide clear photographs via a secure, encrypted clinical platform to help the doctor determine if the growths appear to be viral warts or another skin condition. From there, they can advise on prescription treatments or refer you to a local sexual health clinic for physical intervention like cryotherapy.

While treatment is effective, recurrence is common because the virus can stay in the surrounding skin. To manage the risk:

• Vaccination: If you are eligible, the HPV vaccine is the best protection against the strains that cause 90% of warts.
• Safe Sex: Use condoms, though be aware they do not cover all perianal skin.
• Smoking Cessation: There is evidence that smoking can make it harder for the body to clear HPV and increases the risk of warts returning.
• Check-ups: If you have anal warts, it is often recommended to have a full STI screen to ensure there are no other underlying infections.
