Chlamydia Symptoms, Causes & Testing

Worried you may have chlamydia? Learn what chlamydia is, how it spreads, common symptoms, possible complications, and how testing can give you a clear answer.

What Is Chlamydia?

Chlamydia is a common bacterial sexually transmitted infection (STI). It can affect different parts of the body, including the genitals, rectum, and throat.

One important thing to know: many people with chlamydia have no noticeable symptoms. The only way to know your status for sure is to get tested.

How Is Chlamydia Transmitted?

Chlamydia can be transmitted through:

- Vaginal sex with an infected partner
- Anal sex with an infected partner
- Oral sex with an infected partner

So, yes, you can get chlamydia from oral sex. An infection can occur in the throat after exposure, although throat infections often do not cause noticeable symptoms.

What Are the Symptoms of Chlamydia?

Many people have no symptoms at all, which is why testing is important.

When symptoms do occur, they can include:

In Women

• Unusual vaginal discharge
• Burning or discomfort when urinating
• Lower abdominal or pelvic pain
• Pain during sex
• Bleeding between periods

In Men

• Discharge from the penis
• Burning when urinating
• Pain or swelling around the testicles

Rectal Symptoms
​
​A rectal infection can sometimes cause:

• Rectal pain
• Discharge
• Bleeding

What does chlamydia look like?
There isn't one specific appearance that confirms chlamydia. Symptoms such as discharge or irritation can have several possible causes.

What About Chlamydia Bumps on the Tongue?

A bump on the tongue does not automatically mean you have chlamydia. Mouth or tongue bumps can have many different causes, and throat chlamydia often causes no symptoms. If you are concerned about an STI after oral-sex exposure, testing is a better way to find out than trying to identify the infection by appearance alone.

How Long Can You Have Chlamydia Before It Causes Damage?

There isn't a specific number of days or weeks when chlamydia suddenly causes damage.

Untreated chlamydia can sometimes lead to complications, and the initial damage may go unnoticed. In women, untreated infection can lead to pelvic inflammatory disease (PID), which may cause scarring, ectopic pregnancy, infertility, or long-term pelvic pain. Men can rarely develop complications involving the tubes attached to the testicles.

That is why finding and treating an infection early is important—even when there are no symptoms.

Is Chlamydia Curable?

Yes. Chlamydia is curable with the right antibiotic treatment.

If you test positive, treatment should be provided by a qualified healthcare professional. Don't rely on home remedies or try to treat chlamydia without appropriate medical guidance.

It is also important to avoid reinfection by making sure sexual partners are evaluated and treated as recommended.

How Can You Prevent Chlamydia?

You can lower your risk by:

• Using protection correctly every time you have sex
• Having a mutually monogamous relationship with a partner who has tested negative
• Getting tested when you may have been exposed
• Getting appropriate treatment if you test positive
• Following medical advice about partner testing and treatment

Barrier methods can also reduce the risk of STI transmission during oral sex.
