Trichomoniasis: Causes, Symptoms, and What You Need to Know

When you hear trichomoniasis, a sexually transmitted infection caused by the parasite Trichomonas vaginalis. Also known as trich, it affects millions every year—yet many don’t know they have it. Unlike chlamydia or gonorrhea, trichomoniasis rarely shows up on routine STI screens unless specifically tested for. That’s why it keeps spreading quietly, especially among people who feel fine but have had unprotected sex.

This infection isn’t just about discomfort—it’s a gateway to bigger problems. If left untreated, trichomoniasis can make you more likely to catch or pass on HIV. It’s also linked to complications during pregnancy, like early delivery or low birth weight. Women often notice a foul-smelling, yellow-green discharge, itching, or pain when peeing. Men? They usually have no symptoms at all, which is why they unknowingly pass it on. The parasite doesn’t need much to survive: just moisture, warmth, and contact. It doesn’t live on surfaces, so you can’t catch it from toilet seats or towels—only through direct sexual contact.

What’s surprising is how easy it is to fix. A single dose of metronidazole or tinidazole cures over 90% of cases. But here’s the catch: both partners must be treated at the same time, or you’ll just pass it back and forth. No exceptions. And you need to avoid sex for a full week after treatment—even if symptoms vanish overnight. Too many people skip testing because they’re embarrassed, but trichomoniasis doesn’t care about your shame. It only cares if you’re exposed.

Our collection of posts doesn’t just cover trichomoniasis in isolation. You’ll find real-world connections: how it interacts with other infections like bacterial vaginosis, why some people keep getting it back even after treatment, and how to talk to a partner without fear. We also break down what testing really involves—no judgment, just facts. You’ll see how this infection fits into the bigger picture of sexual health, from prevention to follow-up care.

There’s no magic cure, no miracle supplement, and no reason to suffer in silence. Whether you’re worried about symptoms, just had a risky encounter, or want to protect your partner, the information here is practical, direct, and free of fluff. What follows are real stories, tested advice, and clear steps—no myths, no scare tactics, just what works.
