Lesser-known STI on the rise and causes frothy discharge from vagina and penis

A warning has been issued to the UK public about a sexually transmitted disease that is spreading through the country.

Trichomoniasis is a relatively common but fairly “unknown” disease, spread unknowingly among sexual partners because it often appears with no symptoms.

GP Dr Sameer Sanghvi, clinical technology lead at Lloyds Pharmacy Online Doctor, explained: “As an STI, trich is easy to treat. However, untreated, it can increase your risk of becoming infected with HIV and cause serious complications in pregnant women.

“It’s also often symptomless which means people are more likely to pass it on to others.

“I believe it’s vital people know what trich is, how it spreads, the symptoms to look out for and how testing works," he added to the Express.

“This information will ensure people can make informed decisions about their sexual health.”

What is trichomoniasis?

Trichomoniasis is a sexually transmitted infection (STI) caused by a parasite called Trichomonas vaginalis (TV), the NHS website explained.

It infects both men and women, though research suggests women, ethnic minorities and people from deprived backgrounds are worst affected.

The infection itself may not be particularly damaging, but it can be serious for women as it can cause complications during pregnancy.

How do you catch trichomoniasis?

Trichomoniasis is spread during penetrative sex without the use of a condom.

The TV parasite can also be spread through the use of sex toys.

However, it isn’t passed during oral and anal sex, meaning there is one simple way to avoid catching it.

Using a condom during penetrative sex is one of the simplest ways to reduce your risk, as avoiding multiple sex partners may not necessarily have an impact.

Anyone who is sexually active can catch the parasite, so wearing protection is the best line of defence.

Symptoms of trichomoniasis

Symptoms can vary between men and women.

Women may notice:

  • Changes in the colour, consistency, smell or quantity of vaginal discharge including an unpleasant fishy smell, a yellow-green colour or a thick, thin or frothy consistency
  • Soreness, swelling and itching around the vagina or inner thighs
  • Pain or discomfort when you pee or have sex

While men could have:

  • Pain when you pee or needing to pee more frequently
  • Soreness, swelling and redness around the foreskin or head of the penis
  • Thin, white discharge from the penis
  • Pain during ejaculation

If you have any of the trich symptoms, it is best to contact your GP to help with treatment.
