Chlamydia is a bacterial infection transmitted through genital fluid during unprotected vaginal, oral, or anal sex. It is one of the most common sexually transmitted infections (STIs) in the UK. If left untreated, it can cause more severe conditions, such as pelvic inflammatory disease (PID) in women and infertility in men and women.

As it often presents no symptoms at all, it's essential to get tested. The test for chlamydia is usually a urine or swab test and can be ordered online.

We have medications to treat chlamydia available to order via online prescription. Start a consultation, and our team will check that it's the most suitable treatment for you.

What Are The Causes Of A Chlamydia Infection?

Everyone knows that chlamydia is a sexually transmitted infection, and having unprotected sex puts people at risk. While anyone can get the infection, statistics show that it's more common in young adults, perhaps due to a lack of understanding about safe sex.

Some people believe that chlamydia is only contracted through unprotected penetrative sex, but this isn't the case. Both heterosexual and homosexual people can get chlamydia regardless of whether they have one sexual partner or numerous sexual partners.

Chlamydia can occur when:

-You have sex without protection - including oral sex
-You use sex toys without washing them or covering them with a condom
-You get infected vaginal fluid or semen in your eye
-Your genitals make contact with an infected person's genitals

While it's easy to catch chlamydia, you can't contract it through using towels, hugging or kissing and sharing the bath, cutlery or drinks with other people.


Most people don't show any symptoms of chlamydia, meaning it can be passed on without realising. Symptoms that do appear are usually:

-Pain or bleeding after sex, or bleeding in between periods (women)
-Pain when urinating
-Unusual discharge from the penis or vagina
-Pain and swelling in the testicles (men)

The Complications Of Untreated Chlamydia

Unfortunately, the symptoms of chlamydia can be more subtle than other sexually transmitted infections, so many people don't even know they have it. Catching chlamydia is vital because there can be health complications if not.

For this reason, specialists recommend that people under 25 have a test for sexually transmitted diseases at least once a year or when they have sexual contact with a new person.

Here are some of the complications:

Pelvic Inflammatory Disease

Pelvic inflammatory infections can often be caused by developing an STI, and it can cause severe pain around the abdominal area. Many people also experience pelvic pain while having sex and might notice their periods worsen.

In severe cases, a person might develop a high temperature, ongoing severe pains in the tummy and be sick as a result of the symptoms.

While the infection is treatable with antibiotics, some women might experience problems with fertility later in life - although this is quite rare.


Epididymitis or inflammation of the testicles is a relatively rare side effect of chlamydia in men, but it can cause significant pain. The tubes that carry sperm can become swollen and cause high levels of discomfort.

Reactive Arthritis

Many people aren't aware that a chlamydia trachomatis infection can result in reactive arthritis. According to research from the USA, around one person in 20 will get reactive arthritis due to chlamydia.

For some, the symptoms subside after a few months, but others might develop long-term mild arthritis.

Diagnosing & Treating Chlamydia Trachomatis Infections

Anyone can take a chlamydia test, and they should get tested regularly - even if they don't have any chlamydia symptoms. The local GP or sexual health clinic offers free tests, and they're also available online.
