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
