Trichomonas Vaginalis, or trich, is caused by a one-celled protozoan that grows rapidly within the vagina. Some women have an immediate and painful reaction to trich. Many more have asymptomatic trich; it is often only found if there are tests for other problems. The symptoms include a thin, foamy discharge that is yellow, green, or grey; there is intense itching and soreness, especially if the vulva is scratched. Trich can infect the urinary tract, causing burning, urgency, and frequency. No tiny, one-celled creature should be able to cause such misery. But it does.
Trich can be passed on damp material: towels, bathing suits, washcloths, and toilet seats. This is rare. In most cases, it is transmitted by direct sexual contact. Metronidazole in Flagyl destroys trich. It has side effects, and should not be taken if there is any risk of pregnancy. A partner must be treated. Eschew douches and tampons. Avoid a flare-up recurrence by following the sarne “cool and dry” regime as for yeast overgrowth.
