Chlamydia

Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. It often runs without noticeable symptoms, so a person may not know about the infection for a long time and pass it on to partners. Laboratory tests help to suspect the disease, and confirmed chlamydia is treated by a venereologist or urologist, sometimes with the involvement of a gynaecologist. Without consulting a specialist, the infection can cause complications.

If an infection is suspected, book a routine appointment with a dermatovenerologist, gynaecologist or urologist. An urgent appointment is needed for severe lower abdominal pain, a high temperature or marked deterioration in general wellbeing.

Main

  • Chlamydia is caused by the bacterium Chlamydia trachomatis; the infection is transmitted sexually and often runs without symptoms.
  • The infection is confirmed in the laboratory: a smear or scrape from the genital tract and a molecular test for chlamydia.
  • The condition is managed by a dermatovenereologist, gynaecologist and urologist; if no such specialist is available, start with a general practitioner.
  • The partner is examined and treated if necessary, otherwise reinfection nullifies the result.
  • See a doctor urgently for severe pain in the lower abdomen, a high temperature and tenderness of the testicle.

What is chlamydia

Chlamydia is an infection caused by the bacterium chlamydia, which is transmitted mainly through sexual contact. It often runs unnoticed, but it can cause inflammatory complications.

What happens in the body

Chlamydia enters the human body mainly during unprotected sexual contact and attaches to the cells of the mucous membranes. The bacteria can persist inside cells for a long time without causing noticeable complaints in the carrier. Because of this, hidden inflammation can be maintained for a long time, remaining unnoticed by the person themselves. Gradually, the inflammatory process affects the urogenital organs and can spread to neighbouring structures. In some people, discharge, discomfort or unpleasant sensations in the pelvic area appear. The absence of obvious signs does not mean that there is no inflammation and that it does not affect the tissues. If the infection is left unattended, the risk of long-term inflammatory complications increases, so it is important not to postpone a visit to the doctor if infection is suspected.

What causes it to develop

  • Unprotected sexual contacts: the main route of transmission of the pathogen from person to person, in which the bacteria penetrate the mucous membranes.
  • Changing sexual partner without testing: a new partner may be a carrier of the infection without knowing it, and pass it on during intimacy.
  • The presence of other sexually transmitted infections: they weaken the local protection of the mucous membranes and make it easier for chlamydia to attach to the tissues.
  • Transmission from mother to child during childbirth: while passing through the birth canal, the bacteria can get onto the mucous membranes of the newborn.

Who encounters this more often

Chlamydia is more often detected in people who lead an active sex life and do not use barrier protection. The risk is higher in those who frequently change partners or do not discuss mutual testing with them. Young people encounter the infection more often, since they have a higher likelihood of new acquaintances and casual relationships. The presence of another sexually transmitted infection noticeably increases susceptibility to chlamydia. Women often learn about infection later than men, as the hidden course is more common in them. The absence of complaints does not cancel carriage, so a person can transmit the bacteria without suspecting it. With unprotected contacts with a new partner, it is reasonable to get tested rather than rely on how you feel.

What symptoms can there be?

Chlamydia often runs without noticeable signs, so a person may not suspect the infection for a long time. When symptoms do appear, they depend on which organs are involved, and they can resemble other inflammatory diseases.

How it is noticed at the very beginning

At the beginning, chlamydia often produces no tangible signs, and the person feels quite healthy. The first changes can be so subtle that they are put down to tiredness, a cold or ordinary malaise. Some people notice a slight burning sensation when urinating and do not attach any importance to it. Others develop scanty discharge from the genital tract, which is easily taken for a temporary phenomenon. Women often associate discomfort in the lower abdomen with the approach of menstruation. Men may notice slight discomfort during sexual intercourse and postpone a visit to the doctor. This course leads to the infection being detected by chance or already when complications appear.

Signs that occur most often

  • Discharge from the genital tract: its character and amount change, and the sign itself is easily confused with other inflammatory processes.
  • Burning or pain when urinating: unpleasant sensations arise at the moment of emptying the bladder and recur again.
  • Discomfort or pain in the lower abdomen: a dragging sensation may intensify and interfere with ordinary activities during the day.
  • Bloody discharge between periods: the appearance of blood outside the usual dates is noticeable and requires a doctor's attention.
  • Pain or discomfort during sexual intercourse: such sensations reduce the quality of intimacy and often become a reason for a visit to a specialist.
  • Enlargement or tenderness of the testicle: this sign in men is noticeable on palpation and indicates involvement in the process.

Examinations and tests

Examination for suspected chlamydia begins with a conversation with a doctor and a physical examination, and the infection is confirmed in the laboratory. Below is a breakdown of which tests are used and what each of them shows.

How the examination begins

The first step at an appointment is a detailed conversation, during which the doctor asks about complaints and possible risks of infection. Then they examine the genital organs to assess their condition and notice changes that a person cannot see themselves. Such an examination does not confirm the infection, but it helps to understand which laboratory tests are needed in a particular case. To confirm the infection, laboratory methods are used that detect the causative agent or its genetic material. A urine test and a swab or scrape from the genital tract are among the basic tests prescribed at this stage. A molecular test for chlamydia is considered separately: it targets specifically the causative agent and its genetic material. A sexual partner is examined because without this, reinfection remains possible. Keep all results and records of past visits: they will help the doctor build a complete picture.

What to prepare for the appointment

  • Complaints: write down what bothers you and when, so that the doctor gets an accurate picture rather than an approximate description.
  • Previous results: bring extracts and conclusions of previous examinations, if they were carried out earlier, including tests for infections.
  • Information about your partner: tell whether your partner has been examined and when, because this determines the scope of further tests.
  • List of questions: formulate in advance what you want to clarify with the doctor, so as not to forget anything important during the conversation.
  • Observations of your condition: note whether the complaints have changed over time, as the dynamics help the doctor choose the necessary tests.

Which doctor should I see?

The choice of doctor for chlamydia depends on which organs are involved and who was the first to notice the signs. Below is who manages this condition, what happens at an appointment and what the result depends on.

Which specialist manages this condition

Chlamydia is managed by a dermatovenereologist, and when the genital organs are affected, a gynaecologist and a urologist are also involved. The dermatovenereologist deals with sexually transmitted infections and coordinates the examination as a whole. The gynaecologist examines women, assesses the condition of the cervix and takes material for laboratory confirmation. The urologist manages men who have discharge, discomfort when urinating or changes in the prostate gland. If there is no specialist of this kind nearby, start with a physician: they will listen to the complaints and refer you to the right specialist. At the first appointment, the doctor clarifies the complaints and when they appeared, and gathers information about sexual contacts and past infections. Then they order laboratory confirmation, because treatment is not started without it. Write down your questions in advance: this way the appointment is more focused and clearer.

What treatment consists of

  • Selection of therapy by the doctor: the specialist chooses antibacterial treatment individually, taking into account the examination results, the patient's condition and possible health restrictions.
  • Follow-up until confirmed recovery: the doctor orders repeat tests after treatment to make sure the pathogen is gone and not just that the signs have subsided.
  • Examination and treatment of the sexual partner: the partner is also tested and, if necessary, treated, otherwise reinfection cancels out the whole result.
  • Avoiding sexual contacts during treatment: this condition applies until treatment and tests are completed, and concerns all forms of contact without exception.

What depends on the patient themselves

Regular follow-up determines whether the result will be lasting, and not just quick. If repeat tests are skipped, the doctor will not see the full picture and will not be able to confirm that the pathogen is really gone. A partner who has not been examined remains a source of reinfection, and then everything goes back to the beginning. Some people stop treatment as soon as the unpleasant sensations subside, although external improvement does not equal recovery. Others postpone the visit because of being busy or embarrassed, and during this time the condition may affect new organs. An honest conversation with the doctor about contacts and past episodes helps to select the right treatment the first time. Keep the scheduled test dates and do not change them without agreeing with the specialist.

What helps prevent an exacerbation?

This section explains which everyday habits and regular monitoring reduce the risk of chlamydia flare-ups. It will discuss what a person can change themselves, without relying only on the doctor's prescriptions.

What is changed in habits

Protected sex remains the main habit that reduces the risk of reinfection and flare-ups of chlamydia. A condom is used at every contact until both partners have been tested and are sure there is no infection. Giving up the condom before a partner has been tested creates a risk of new infection even after completed treatment. Regular testing when changing partners helps to notice the pathogen in time and not let the inflammation progress. When planning a pregnancy, testing for infections protects the unborn child from transmission of the pathogen. Timely consultation with a doctor when symptoms appear prevents the process from becoming latent. A calm attitude to testing and an open conversation with a partner reduce anxiety and help not to postpone the visit.

What should be kept under control

  • Protected sex: consistent use of a condom reduces the risk of reinfection and flare-ups, especially when changing partners.
  • Partner testing: testing before starting sexual life without a condom helps to make sure that both people are healthy.
  • Regular check-ups: testing for sexually transmitted infections allows the pathogen to be noticed before complaints appear.
  • Planning a pregnancy: testing for infections before conception reduces the risk of transmission of the pathogen to the unborn child.
  • Appearance of symptoms: timely consultation with a doctor at the first signs prevents the inflammation from becoming latent.
  • Open conversation with a partner: an honest exchange of information about testing helps both not to postpone a visit to the doctor.

How often to see a doctor

Regular monitoring by a doctor is needed even when well-being remains good and there are no complaints. Chlamydia often runs latently, so the absence of symptoms does not mean the absence of the pathogen. Testing when changing partners helps to notice the infection in time and not let the inflammation progress. When planning a pregnancy, testing is done in advance to protect the unborn child from transmission of the pathogen. If symptoms appear, the visit to the doctor is not postponed, and one does not wait until it gets better. Regular testing for sexually transmitted infections gives peace of mind and allows monitoring to be adjusted in time. An open conversation with the doctor about habits and partners helps to build a clear monitoring plan. Such monitoring does not replace the prescribed treatment, but it reduces the risk of flare-ups and reinfection.

What is worth remembering

A conversation about chlamydia ends not with a list of prohibitions, but with an understanding of how this infection works and what truly depends on the person. Below are the conclusions that help make a calm and balanced decision.

Main conclusions

Chlamydia often runs unnoticed, so how you feel is not a reliable guide when assessing the situation. A person may feel perfectly healthy, while the pathogen persists in the body and is passed on to a partner. Infection is not related to personal hygiene or lifestyle, so reproaches and looking for someone to blame are pointless here. You should not put off a visit to the doctor if you suspect something: the earlier observation begins, the lower the risk of long-term consequences. The situation needs to be discussed openly with your sexual partner, because testing and observation concern you both. Chlamydia is treated only by a doctor, and trying to figure it out on your own on the internet often leads to mistakes. Chlamydia is not a sentence, but a manageable infection that can be dealt with through attentive care for yourself.

Questions and answers

Answered by the article’s medical editor.

How does chlamydia manifest in children?

In children it usually manifests as an infection of the eyes or respiratory tract. Infection occurs during passage through the mother's birth canal if she has not been tested. The newborn develops redness of the eyelids, swelling and discharge from the eyes. Less commonly, the respiratory tract is affected, which manifests as a cough and difficulty breathing. Such a child is examined by a doctor, and the mother is tested for infections.

How does chlamydia differ in older people?

In no fundamental way: the course is the same as in people of other ages. The infection is transmitted sexually, so the risk remains with unprotected contacts at any age. In older people, symptoms are more often attributed to age-related changes or other diseases of the urogenital system. Because of this, a visit to the doctor is postponed, and the inflammation continues. If suspected, testing is carried out in the same way as at a younger age.

What tests should be taken to check for chlamydia?

The main method is a molecular test that detects the genetic material of the pathogen. The material is taken from the genital tract or from urine, depending on what is causing concern. A urine test and examination help assess signs of inflammation, but do not themselves confirm the infection. Sexual partners are also tested, otherwise reinfection remains possible. The exact list of investigations is determined by the doctor based on complaints and history.

Can you get chlamydia in a sauna or swimming pool?

No, it is not transmitted by household means through water, handrails or shared towels. The pathogen is unstable outside the body and dies in water and on surfaces. The main route of transmission is unprotected sexual contact. Infection is also possible from mother to child during childbirth. Therefore, a shared sauna or swimming pool by itself does not create a risk.

Can you do sports during treatment?

Usually yes, moderate exercise is not prohibited and does not interfere with observation by a doctor. If there is pain in the lower abdomen, fever or pronounced malaise, it is better to postpone training until you feel better. Heavy exercise during the acute period is tolerated worse and interferes with recovery. It is worth abstaining from sexual contacts until the doctor completes the tests. Specific restrictions are discussed with a specialist at the appointment.

How does chlamydia affect pregnancy?

The infection can be transmitted to the child during passage through the birth canal. In the newborn this manifests as inflammation of the eyes or respiratory tract. In the woman herself, a hidden inflammation can affect the pelvic organs. Therefore, testing for infections is carried out in advance, even when planning a pregnancy. Such a pregnancy is managed by a gynaecologist together with a dermatovenereologist.

What complications occur if you do not see a doctor?

Without observation by a specialist, the inflammation can spread to neighbouring organs. In women this affects the uterus and appendages, in men — the prostate gland and epididymis. The hidden course can maintain inflammation for a long time, remaining unnoticed. The long-term consequences concern reproductive function. The earlier observation is started, the lower the risk of such changes.

When should you seek urgent help with chlamydia?

Urgently — with severe pain in the lower abdomen, high fever or pronounced deterioration in well-being. In men, an enlargement or tenderness of the testicle becomes a reason for an immediate visit to a urologist. These signs indicate involvement in the process and require examination without delay. In other cases, a routine appointment with a dermatovenereologist, gynaecologist or urologist is sufficient. It is not worth delaying a visit if infection is suspected.

Which doctor should you go to if there is no specialist nearby?

To a general practitioner: he will listen to the complaints and refer you to the right specialist. Chlamydia is managed by a dermatovenereologist, in women a gynaecologist is involved, in men — a urologist. The general practitioner does not replace them, but helps to build the route of examination. At the appointment it is important to tell about the complaints, their duration and sexual contacts. Questions written down in advance make the conversation more focused.

How long do you need to be observed by a doctor after starting the examination?

As long as the doctor needs for repeat tests after therapy. External improvement does not mean that the pathogen is gone, so the tests are not skipped. The partner is also tested, otherwise reinfection brings the result back to the start. The dates of follow-up visits are set by the specialist, and they should not be changed without agreement. The regularity of observation determines the durability of the result.
