Gonorrhea & Chlamydia: The Pair Everyone Gets Tested For
Gonorrhea and chlamydia are two of the most common sexually transmitted infections — and they’re often talked about in the same breath for a reason. They spread in similar ways, are tested for using the same types of samples, and come up in many of the same conversations around screening and treatment.
That doesn’t mean they’re identical. Think of them more like evil stepsisters: related, frequently confused for one another, and often mentioned together — but very much their own characters.
Let’s break them down without overcomplicating things.
What Are Gonorrhea and Chlamydia?
Gonorrhea and chlamydia are both bacterial STIs. They can infect the cervix, vagina, urethra, rectum, throat, and even the eyes, depending on the type of sexual contact involved.
They spread through:
· Vaginal sex
· Anal sex
· Oral sex
Because they sometimes cause few or no symptoms, many people don’t know they have them — which is why routine testing matters.
What Do They Feel Like?
This is where gonorrhea and chlamydia overlap and diverge.
Symptoms also depend on where in the body the infection has taken hold. For example, a vaginal infection won’t cause throat pain, and a throat infection may cause no symptoms at all.
Chlamydia
Chlamydia is especially known for being quiet.
Many people have no symptoms at all. When symptoms do happen, they may include:
· Abnormal vaginal discharge
· Pelvic discomfort
· Pain with sex
· Burning with urination
Because it can linger silently, chlamydia is a common contributor to long-term complications when it goes untreated.
Gonorrhea
Gonorrhea is more likely to cause noticeable symptoms, though it can still be silent.
Symptoms may include:
· Thick, yellow or green discharge
· Pelvic pain
· Burning with urination
· Rectal pain, discharge, or bleeding (with rectal infection)
· Sore throat (with throat infection)
That said, absence of symptoms does not mean absence of infection.
How Are Gonorrhea and Chlamydia Diagnosed?
Testing is straightforward.
Both infections are diagnosed using:
· Vaginal swabs
· Urine tests
· Rectal or throat swabs, if indicated
Testing sites depend on exposure — and this part is often missed.
While many providers include testing for vaginal infection as part of routine STI screening, they may not think to ask about the throat or rectum. If you’re engaging in oral or anal sex and it’s not explicitly discussed, you’re allowed to ask your provider to test those areas as well — especially if you’ve had new or multiple partners.
How Are Gonorrhea and Chlamydia Treated?
Both infections are curable with antibiotics, but treatment depends on which infection is present and local resistance patterns.
Chlamydia is typically treated with doxycycline, taken twice a day for seven days.
Gonorrhea is currently treated with a single injection of ceftriaxone, with the dose based on weight.
Because symptoms overlap — and because the infections can occur together — providers may treat for both at the same time if symptoms are present or there was a known exposure, unless test results have already returned.
As with any STI:
· Take all prescribed medication exactly as directed
· Avoid sex until treatment is complete
· Make sure partners are treated to prevent reinfection
A Note on Gonorrhea Resistance
Most gonorrhea infections still respond well to standard treatment. However, antibiotic resistance has increased over time, which is why treatment recommendations have changed — and may continue to change in the future.
If symptoms don’t improve after treatment, or return shortly afterward, follow up with your provider. You may need repeat testing or additional evaluation.
When Will Symptoms Get Better?
Symptoms often begin to improve within a few days of starting treatment, but that doesn’t mean the infection is gone.
Finish the entire course of antibiotics, even if you feel better sooner. Most providers recommend avoiding sex for at least seven days after completing treatment, and until all partners have been treated.
What About Partners?
Partners should be treated even if they don’t have symptoms.
Reinfection is common if only one person is treated. This isn’t about blame or assumptions — it’s about preventing a cycle where the infection keeps getting passed back and forth.
Can Gonorrhea or Chlamydia Cause Complications?
Yes — especially if untreated.
Both infections can increase the risk of:
· Pelvic inflammatory disease (PID)
· Chronic pelvic pain
· Infertility
· Ectopic pregnancy
The risk isn’t about how bad the infection feels — it’s about how long it’s present without treatment.
How Can You Prevent Gonorrhea and Chlamydia?
Using hormonal birth control (like the pill, patch, ring, or IUD) does not protect against STIs.
The only reliable ways to reduce risk are:
· Not having sex
· Using condoms consistently and correctly
When used properly, condoms significantly reduce the risk of gonorrhea and chlamydia, though no method is perfect. Using them more often is still far better than not using them at all.
What Is Doxy-PEP?
Doxy-PEP (doxycycline post-exposure prophylaxis) is a newer prevention strategy used in specific high-risk populations.
It involves taking doxycycline after sex to reduce the risk of acquiring certain bacterial STIs, particularly:
· Chlamydia
· Syphilis
· Gonorrhea (with more limited protection)
Current evidence supports its use primarily in:
· Men who have sex with men
· Transgender women
· People with a history of frequent bacterial STIs
Doxy-PEP is not for everyone and isn’t a replacement for regular testing or condom use. It’s a targeted harm-reduction tool that should be discussed with a knowledgeable provider.
Are Gonorrhea and Chlamydia Serious?
When diagnosed and treated promptly, both infections are very manageable.
They don’t define you, they don’t mean you were careless, and they don’t require shame. The real risk comes from not knowing they’re there — which is why testing matters more than symptoms.
The Bottom Line
Gonorrhea and chlamydia are common, often silent, and completely treatable. They’re frequently discussed together because they’re tested for and managed in similar ways — even though they’re not the same infection.
If you’re diagnosed, it doesn’t mean you did anything wrong. It just means you caught something that spreads easily and responds well to treatment.
