Trichomoniasis | Causes, Symptoms, Diagnosis & Treatment | STI Explained by Doctor

Trichomoniasis: the most common non-viral sexually transmitted infection—learn how to recognize, diagnose, and treat Trichomonas vaginalis to protect reproductive health. Trichomoniasis and Trichomonas vaginalis are covered in this concise, clinical guide that explains symptoms, transmission, diagnosis, complications, and treatment. Viewers will learn the hallmark signs—frothy, foul-smelling yellow-green vaginal discharge, genital itching, pain during intercourse, and urinary symptoms—while noting that many men remain asymptomatic yet infectious. The video explains the parasite’s biology (a flagellated protozoan with characteristic motility), incubation (5–28 days), and how it damages the urogenital epithelium, raising vaginal pH and often coexisting with bacterial vaginosis. Practical diagnostic guidance is provided: nucleic acid amplification testing (NAAT) is the gold standard, while microscopy and culture remain useful in some settings. Key complications—preterm labor, low birth weight, pelvic inflammatory disease, and increased HIV risk—underscore why timely detection matters. Treatment options are clearly outlined: single-dose oral metronidazole or tinidazole, partner treatment, and extended regimens for people with HIV. Risk reduction strategies—consistent condom use, routine STI screening, and treating sexual partners—are emphasized to prevent reinfection and protect pregnancy outcomes. This informative, clinically focused video arms clinicians, students, and sexually active viewers with the essential facts to identify, manage, and prevent trichomoniasis. Watch to gain actionable diagnostic tips and treatment strategies that reduce complications and transmission.
