Chlamydia is a common sexually transmitted infection (STI) caused by bacteria. People who have chlamydia often don’t have outward symptoms in the early stages.
In fact, about 90 percent of women and 70 percent of men with the STI have no symptoms. But chlamydia can still cause health problems later.
Untreated chlamydia can cause serious complications, so it’s important to get regular screenings and talk with your doctor or healthcare provider if you have any concerns.
Chlamydia can cause a vaginal discharge. It may resemble pus or mucus.
Symptoms of chlamydia may be similar to symptoms of other STIs.
Sex without a condom and unprotected oral sex are the main ways a chlamydia infection can be transmitted. But penetration doesn’t have to occur to contract it.
Touching genitals together may transmit the bacteria. It can also be contracted during anal sex.
Newborn babies can acquire chlamydia from their mother during birth. Most prenatal testing includes a chlamydia test, but it doesn’t hurt to double-check with an OB-GYN during the first prenatal checkup.
A chlamydia infection in the eye can occur through oral or genital contact with the eyes, but this isn’t common.
Chlamydia can also be contracted even in someone who’s had the infection once before and successfully treated it.

Statistically, a person is more likely to get an STI if they’ve had sex with more than one person. Other risk factors include having had an STI in the past, or currently have an infection, because this could lower resistance.
An act of sexual assault can raise the risk for contracting chlamydia and other STIs. If you were forced into any sexual activity, including oral sex, aim to get screened as soon as possible.

Rates for chlamydia and other STIs have been climbing in recent years.
Many men don’t notice the symptoms of chlamydia. Most men have no symptoms at all.
If symptoms do appear, it’s usually 1 to 3 weeks after transmission.
Some of the most common symptoms of chlamydia in men include:
- burning sensation during urination
- yellow or green discharge from the penis
- pain in the lower abdomen
- pain in the testicles
It’s also possible to get a chlamydia infection in the anus. In this case, the main symptoms are often discharge, pain, and bleeding from this area.
Having oral sex with someone who has the infection raises the risk for getting chlamydia in the throat. Symptoms can include a sore throat, cough, or fever. It’s also possible to carry bacteria in the throat and not know it.
Chlamydia is often known as the “silent infection.” That’s because people with chlamydia may not experience symptoms at all.
If a woman contracts the STI, it may take several weeks before any symptoms appear.
Some of the most common symptoms of chlamydia in women include:
- painful sexual intercourse (dyspareunia)
- vaginal discharge
- burning sensation during urination
- pain in the lower abdomen
- inflammation of the cervix (cervicitis)
- bleeding between periods
In some women, the infection can spread to the fallopian tubes, which may cause a condition called pelvic inflammatory disease (PID). PID is a medical emergency.
The symptoms of PID are:
- fever
- severe pelvic pain
- nausea
- abnormal vaginal bleeding between periods
Chlamydia can also infect the rectum. Women may not experience symptoms if they have a chlamydia infection in the rectum. If symptoms of a rectal infection do occur, however, they may include rectal pain, discharge, or bleeding.
Additionally, women can develop a throat infection if they perform oral sex on someone with the infection. Though it’s possible to contract it without knowing it, symptoms of a chlamydia infection in your throat include cough, fever, and sore throat.
The symptoms of STIs in men and women can be different, so it’s important to talk to a healthcare professional if you experience any of the above symptoms.
The good news is that chlamydia is easy to treat. Since it’s bacterial in nature, it’s treated with antibiotics.
Azithromycin is an antibiotic usually prescribed in a single, large dose. Doxycycline is an antibiotic that must be taken twice per day for about one week.
Other antibiotics may also be given. No matter which antibiotic is prescribed, dosage instructions should be followed carefully to make sure the infection clears up fully. This can take up to two weeks, even with the single-dose medications.
During the treatment time, it’s important not to have sex. It’s still possible to transmit and contract chlamydia if exposed again, even if you’ve treated a previous infection.
Although chlamydia is curable, it’s still important to stay protected and prevent recurrence.
Chlamydia is caused by a bacterial infection. The only true cure for this type of infection is antibiotics.
But some alternative treatments may help ease symptoms. It’s important to remember that untreated chlamydia can lead to long-term complications, including fertility problems and chronic inflammation.
Home remedies for chlamydia that may be effective (for symptoms, not the infection itself) include:
- Goldenseal.This medicinal plant may limit symptoms during an infection by reducing inflammation.
- Echinacea. This plant has been widely used to boost the immune system in order to help people overcome infections of many types, from the common cold to skin wounds. It may help reduce symptoms of chlamydia.
Although compounds in these plants might help to ease inflammation and infection in general, there aren’t any quality studies that show they’re effective specifically for chlamydia symptoms.
When seeing a healthcare professional about chlamydia, they’ll likely ask about symptoms. If there are none, they may ask why you have concerns.
If symptoms are present, the doctor may perform a physical exam. This lets them observe any discharge, sores, or unusual spots that may be related to a possible infection.
The most effective diagnostic test for chlamydia is to swab the vagina in women and to test urine in men. If there’s a chance the infection is in the anus or throat, these areas may be swabbed as well.
Results may take several days. The doctor’s office should call to discuss results. If the test returns positive, a follow-up appointment and treatment options will be discussed.
STI testing can be done in several ways.
If a healthcare provider is seen as soon as chlamydia is suspected, the infection will likely clear up with no lasting problems.
However, people may experience serious medical issues if they wait too long to treat it.
Female complications of untreated chlamydia
Some women develop PID, an infection that can damage the uterus, cervix, and ovaries. PID is a painful disease that often requires hospital treatment.
Women can also become infertile if chlamydia is left untreated because the fallopian tubes may become scarred.
Pregnant women with the infection can pass the bacteria to their babies during birth, which can cause eye infections and pneumonia in newborns.
Male complications of untreated chlamydia
Men can also experience complications when chlamydia is left untreated. The epididymis — the tube that holds the testicles in place — may become inflamed, causing pain. This is known as epididymitis.
The infection can also spread to the prostate gland, causing a fever, painful intercourse, and discomfort in the lower back. Another possible complication is male chlamydial urethritis.
These are just some of the most common complications of untreated chlamydia, which is why it’s important to get medical attention right away. Most people who get treatment quickly have no long-term medical problems.
STIs can also be transmitted and contracted during oral sex. Contact with the mouth, lips, or tongue may be enough to transmit chlamydia.
If you contract chlamydia from oral sex, you may experience no symptoms. Like vaginal or anal chlamydial infections, symptoms don’t always appear.
If symptoms are present with chlamydia in the throat, they can include:
Other STIs can develop in the throat. Each type of STI in the throat cause unique symptoms and concerns.
A chlamydia infection is most common in the genital area, but it can occur in less common places like the anus, throat, and even the eyes. It can occur in the eyes through direct or indirect contact with the bacterium.
For example, the infection can go from the genitals to the eye if you touch your eye without washing your hands.
If you have a chlamydia eye infection, also known as chlamydial conjunctivitis, the following symptoms may occur:
- redness
- swelling
- itching
- irritation
- mucus or discharge
- sensitivity to light (photophobia)
If left untreated, chlamydia in the eye can lead to blindness. But it’s easily treated, and early treatment will help cure the infection and prevent complications.
Chlamydia in the eye may be confused with more common eye infections.
Chlamydia and gonorrhea are two common STIs. Both are caused by bacteria that can be passed during vaginal, oral, or anal sex.
Both STIs are unlikely to cause symptoms. If symptoms do occur, people with chlamydia experience the first signs within a few weeks of contracting the infection. With gonorrhea, it can be much longer before symptoms appear, if at all.
Both infections share some similar symptoms. These include:
- pain or burning during urination
- an abnormal discharge from the penis, vagina, or anus
- swelling in the testicles or scrotum
- rectal pain
- bleeding from the rectum
The two infections can also lead to pelvic inflammatory disease and reproductive issues if left untreated.
Untreated gonorrhea can lead to itching, soreness, and pain in the rectum, such as during bowel movements. Women with untreated gonorrhea may also experience prolonged, heavy periods and pain during intercourse.
Both chlamydia and gonorrhea can be treated effectively with antibiotics. They’re both curable and unlikely to cause long-term issues if treated quickly.
Several other key differences help distinguish between the two STIs.
The surest way for a sexually active person to avoid contracting chlamydia is to use a condom during sexual intercourse.
To practice safe sex, it’s recommended to:
- Use protection with each new partner.
- Get tested regularly for STIs with new partners.
- Avoid having oral sex, or use protection during oral sex, until a partner has been screened for STIs.
Safe sex can protect everyone from infections, unintended pregnancy, and other complications. Safe sex is incredibly successful if done correctly.
