Chlamydia May Mimic Menstrual Pain, Doctors Warn

Many women experience menstrual pain without raising concerns, yet medical professionals warn that shifts in the character of this discomfort—or the emergence of accompanying symptoms—can occasionally signal a sexually transmitted infection.

How chlamydia symptoms overlap with common gynaecological complaints

Experts note that chlamydia—a bacterial infection—often presents with signs easily mistaken for routine menstrual cramps or urinary tract infections. This similarity can delay both diagnosis and treatment.

Dr. Asia Moola, a general practitioner at The Health Suite in Leicester, explains that some patients report intensified menstrual pain or prolonged duration beyond their usual cycle. Others observe intermenstrual spotting. Additional indicators include pain during sexual intercourse, burning sensation while urinating, and unusual vaginal discharge.

According to Dr. Moola, these manifestations frequently resemble other non-infectious gynaecological conditions. As a result, women may seek relief for individual symptoms without identifying the underlying cause.

Complications of untreated chlamydia

If left unaddressed, chlamydia can spread to the uterus and fallopian tubes, potentially triggering pelvic inflammatory disease (PID). PID carries risks of fertility impairment and ectopic pregnancy.

Notably, PID may develop asymptomatically, meaning its detection could be delayed for years.

When to seek testing

Menstrual pain alone does not confirm a sexually transmitted infection. However, clinicians advise testing when women notice a marked change in pain pattern, intermenstrual bleeding, coital pain, or atypical discharge.

Testing typically involves either a urine sample or a swab. In most cases, chlamydia is treated with a short course of antibiotics.
