Trichomoniasis: Causes, Symptoms and Treatment

It is an infection caused by a unicellular protozoon called Trichomonas.

Which is one of the most common causes of vaginal infections. It is also known as Trichomonas vaginitis.


Usually, it is limited to the vagina; this organism can invade the urinary tract and cause cystitis (inflammation of the bladder). The Trichomonas can also be severe enough to trigger an abnormal Pap smear. The body can be detected and reappear; However, it can cause tiny red lesions in the cervix and the fallopian tubes, although they do not affect fertility.


Trichomonas can be transmitted in many cases through sexual intercourse. However, a history compatible with sexual transmission may not be documented.

Symptoms of Trichomoniasis

Yellow or green discharge, frothy bubbles sometimes with a foul odor, and itching, pain, and inflammation of the vulva and vagina. Men usually harbor the body in their urinary tract and have no symptoms.


A complete medical history and a physical examination will be carried out, including a pelvic exam. The doctor will collect a wet spot by mixing a sample of the vaginal discharge with a drop of saline (physiological saline solution) and examining it under a microscope.

Organisms such as Trichomonas can be easily identified since they swim very quickly due to their whip-like tail. They also cause small red, dark spots (petechiae) on the cervix, and vaginal secretions tend to be more alkaline than usual, where the doctor can use a strip of paper to check the acidity. The pH is likely to exceed 5.0.


Treatment for Trichomoniasis

The most effective medication for treatment is metronidazole. The dose is usually 2000 mg in a single dose or 500 mg twice daily for seven days. However, if the infection persists, the patient’s sexual partner should also be treated.

Side effects of metronidazole may include an allergic reaction, nausea, diarrhea, dry mouth, a metallic taste, a decrease in white blood cell count (leukopenia), and alcohol intolerance.

People who drink alcohol in the next 24 hours after handling metronidazole can trigger nausea, vomiting, headache, and flushing. The metronidazole should not be used during the first three months of pregnancy or while breastfeeding; even some scientists recommend not handle throughout pregnancy.
