What should you know about intestinal trichomoniasis symptoms?

Trichomoniasis usually affects the genital tract; intestinal symptoms are not typical and should be assessed rather than assumed to be caused by this infection. Genital symptoms can include unusual discharge, itching, irritation or discomfort when passing urine, while some people have no symptoms.

The infection is caused by a parasite and is passed mainly through sexual contact. Symptoms can vary between partners and may appear after an interval, so timing alone cannot confirm the cause. Vaginal discharge or vaginal itching may have several explanations, including other infections. Persistent abdominal, rectal or bowel symptoms need their own clinical assessment because they may arise from a gastrointestinal condition, another infection or irritation.

Arrange testing with a sexual-health clinician or GP if you have new genital symptoms or a partner has been diagnosed. Testing may involve a swab or urine sample, depending on the service and symptoms. Avoid sex until you have received advice about treatment and partner management. Take prescribed medicine exactly as directed and tell the clinician about pregnancy, allergies and other medicines. Antibiotic Treatment for Pelvic Infection is a related treatment pathway, but the correct medicine depends on the diagnosis.

Seek prompt care for pelvic pain, fever, vomiting, bleeding after sex, pain during pregnancy or feeling very unwell. Get urgent help for severe abdominal pain, fainting or heavy bleeding. Any bowel or rectal symptom that is persistent, severe or accompanied by blood should be assessed directly rather than attributed to trichomoniasis.

Which tests are appropriate for my symptoms? Could another infection explain the bowel or genital changes? Do sexual partners need testing or treatment? When is it safe to resume sex? Do I need a review after treatment?
