Trichomoniasis
Trichomoniasis is a sexually transmitted infection caused by a parasite called Trichomonas vaginalis.
Symptoms
Some people who are infected with trichomoniasis have no symptoms.
However, women may experience the following symptoms:
​
-
Green or yellow discharge from the vagina. The discharge may also be frothy and have an unpleasant, fishy smell.
-
Pain, itching and/or swelling around the vagina and thighs
-
Pain or discomfort during sex
-
Painful urination
Diagnosis
If you think you may have trichomoniasis, you should see your doctor or attend a sexual health clinic.
​
The doctor will ask you about your sexual history and symptoms. They will also examine the genital area and may perform an internal examination.
​
If the doctor suspects you may have trichomoniasis then they will perform some tests such as swabs of the vagina or a urine sample.
Treatment
If you are diagnosed with trichomoniasis or there is high suspicion that you may have trichomoniasis, your doctor will prescribe a course of antibiotics (e.g. metronidazole).
​
Your doctor will also advise you to avoid sexual intercourse for 7 days.
​
You should also contact any recent sexual partners as they may also be infected with trichomoniasis. This includes any individual with whom you have had sexual intercourse within 6 months.
Complications
If trichomoniasis is left untreated, a woman may be at risk of the following complications:
​
-
Complications of pregnancy e.g. premature birth or low birth weight
-
Increased risk of contracting other STIs including HIV
-
Pelvic inflammatory disease
