Genital warts - causes and treatment
Written in association with:Genital warts are usually transmitted in adults via sexual activity. Many people are unaware of what to look for and a dermatologist with experience in vulval skin conditions, such as Dr Moumita Chattopadhyay, will be able to identify genital warts and recommend a course of treatment. Here she explains what to expect.
What causes genital warts
The low-risk human papillomavirus (HPV) is the main cause of genital warts. There are various types of HPV, and the ones usually associated with genital warts are type 6 and 11. Most types of HPV are harmless and can disappear within a few weeks without medical assistance. However, if you have genital warts, you’ll need treatment.
It's important to note that genital warts can be contracted from skin-to-skin contact or from sharing sex toys, not only from penetrative sex. Therefore, a condom does not offer 100% protection against HPV and therefore genital warts.
How is it diagnosed? What to look for.
You can have the genital warts virus without knowing so. When genital warts appear, they can look like:
- Small papules – these elevated skin spots range from small to large. They may appear like a dome or be flat.
- Cauliflower shaped growths – these are skin coloured and bumpy.
They can appear at any site in the vulva or the vagina, but the most common site is the fold of skin at the bottom of the entrance to the vagina – this is medically referred to as the posterior fourchette.
Treatment for genital warts
If you are diagnosed with genital warts, the treatment you receive depends on:
- The number of warts
- The size of the warts
- The position of the warts
Your dermatologist can prescribe you with topical treatments such as:
- Imiquimod 5% cream – an immune response modifier which also reduces the chance of recurrence
- Podophyllotoxin - a cream
- Trichloroacetic acid – a chemical treatment
- Liquid nitrogen cryotherapy – this freezes warts to destroy them
When topical treatments might not work
If a patient has a suppressed immune system due to already-existing conditions or treatments, it’s possible that standard treatment won’t work and the warts won’t be removed. This is because an immune response against the virus is essential in order to remove warts.
Furthermore, if the warts become keratinized, meaning the skin becomes filled with keratin and is hard, they may not respond well to treatment, and therefore your dermatologist may need to perform surgery to curette them off.
Cervical smears
If you have genital warts, you can get other types of HPV which cause cervical diseases. For this reason, it’s very important that you receive a cervical smear test.
