Gonorrhea is one of the most common sexually transmitted infections (STIs), caused by the bacterium Neisseria gonorrhoeae.

This bacterium can infect different areas of the body, including the genital tract, rectum, and throat. Gonorrhea can affect men and women, and if it is not treated, it can lead to serious problems and long-term complications.

Symptoms of gonorrhea

Gonorrhea is caused by Neisseria gonorrhoeae, a bacterium transmitted through sexual contact. This contact may include vaginal, anal, or oral sex.

Mothers with gonorrhea can also transmit the infection to their babies during childbirth.

Symptoms of gonorrhea vary depending on the infected site, and some people may have no symptoms at all. The most common symptoms include:

Symptoms of gonorrhea in men

  1. Discharge from the penis

One of the first symptoms of gonorrhea in men is a thick yellow or green discharge from the penis.

  1. Pain or burning during urination

Men with gonorrhea often develop pain or a burning sensation when urinating.

  1. Pain or swelling in one testicle

This symptom is less common, but it can suggest a more advanced infection.

  • 4. Blood in the semen

Hematospermia (blood in the semen) is a symptom that can occur for several reasons, including gonorrhea.

Symptoms of gonorrhea in women

  1. Abnormal vaginal discharge

Abnormal vaginal discharge that may be yellow or green.

  1. Pain or burning during urination

Women may also develop pain or a burning sensation when urinating.

  1. Bleeding between menstrual periods

Abnormal bleeding between menstrual periods can be one symptom of gonorrhea.

  1. Lower abdominal or pelvic pain

This symptom is usually seen in more advanced infections.

Symptoms of gonorrhea in other body sites

  1. Rectal infection

Symptoms include itching, discharge, pain during bowel movements, and bleeding.

  1. Throat infection

Gonorrhea of the throat can cause sore throat, swollen tonsils, and purulent throat discharge.

  1. Eye infection

Especially in newborns, gonorrhea can cause eye discharge, redness, and swelling.

Diagnosis of gonorrhea

Diagnosing gonorrhea requires accurate testing and medical evaluation.

Several methods can be used to diagnose this infection:

  1. Sampling from the infected site

The doctor may take a sample of discharge from the infected site for testing. These samples may come from the genital area, rectum, or throat.

  1. Urine test

A urine test can also be used to diagnose gonorrhea. This method is especially useful for men who do not have discharge symptoms.

  1. Specialized laboratory tests

Molecular tests such as PCR (polymerase chain reaction) can help provide a more accurate diagnosis. These tests work by detecting the DNA of Neisseria gonorrhoeae.

Treatment methods for gonorrhea

Gonorrhea is usually treated with antibiotics. The choice of antibiotic and treatment duration depends on the patient's condition and possible bacterial resistance to antibiotics.

  1. Antibiotics

    • Cefixime (Cefixime) and Ceftriaxone (Ceftriaxone)

These two antibiotics are often prescribed for gonorrhea. Ceftriaxone is usually given by injection.

  • Azithromycin (Azithromycin)

It is sometimes prescribed together with ceftriaxone to reduce bacterial resistance.

  1. Treatment of the sexual partner

    • Treating the patient's sexual partner at the same time is very important to prevent reinfection and further spread.

  2. Follow-up and repeat testing

    • After completing treatment, the patient should be tested again to confirm that treatment was successful. This is especially necessary when symptoms continue or return.

Prevention of gonorrhea

Preventing gonorrhea requires several simple but effective measures:

  1. Condom use

Correct and consistent condom use during every type of sexual contact can significantly reduce the risk of gonorrhea.

  1. Regular testing

Sexually active people, especially those with multiple sexual partners, should be tested regularly.

  1. Sexual health precautions

Avoiding sexual contact with people who have, or may have, sexually transmitted infections and maintaining personal hygiene can help prevent gonorrhea.

  1. Education and awareness

Sexual health education and increased awareness about sexually transmitted infections and ways to prevent them play an important role in controlling the spread of these infections.

Possible complications of gonorrhea

If left untreated, gonorrhea can lead to serious problems and long-term complications:

  1. Infertility

Gonorrhea can cause infertility in both sexes. In women, it can lead to pelvic inflammatory disease (PID), one of the common causes of infertility. In men, long-term infection can lead to epididymitis (inflammation of the epididymis), which, if untreated, can cause infertility.

  1. Disseminated gonococcal infection (DGI)

If Neisseria gonorrhoeae enters the bloodstream, it can cause serious and life-threatening infections. Symptoms of DGI include fever, joint pain, skin lesions, and arthritis.

  1. Eye infection

In newborns, transmission of gonorrhea from the mother can lead to an eye infection that may cause blindness if untreated. For this reason, babies born to mothers with gonorrhea should receive preventive treatment immediately after birth.

  1. Problems during pregnancy

Gonorrhea during pregnancy can lead to preterm birth, premature rupture of membranes, and postpartum infections.

Conclusion

Gonorrhea is a common and preventable sexually transmitted infection that can lead to serious problems if left untreated.

Early diagnosis and appropriate antibiotic treatment can prevent serious complications and lead to full recovery.

Education, awareness, and sexual health precautions play an important role in preventing the spread of this infection.

Sexually active people should be tested regularly and should see a doctor promptly if they notice any suspicious symptoms.

Treating sexual partners at the same time is also very important to prevent reinfection and further spread of the infection.

By following these measures, it is possible to prevent gonorrhea and its spread and to help protect the sexual and general health of the community.
