Gonorrhea: Symptoms, Causes, Treatment, and Prevention

Overview

Gonorrhea is a sexually transmitted infection (STI) caused by the bacterium Neisseria gonorrhoeae. It can infect both men and women and is one of the most common STIs worldwide. According to the Centers for Disease Control and Prevention (CDC), there were over 677,000 reported cases of gonorrhea in the United States in 2020, making it the second most commonly reported bacterial STI after chlamydia.

Gonorrhea primarily affects the urethra, rectum, or throat, but it can also infect the cervix in women. If left untreated, it can lead to serious health complications, including infertility and an increased risk of HIV transmission.

Symptoms

Many people with gonorrhea, especially women, may not experience any symptoms. When symptoms do occur, they can vary depending on the site of infection.

Symptoms in Men

• Painful urination (dysuria): A burning sensation when urinating.
• Penile discharge: White, yellow, or green discharge from the penis.
• Testicular pain or swelling: Due to inflammation of the epididymis (epididymitis).

Symptoms in Women

• Vaginal discharge: Increased or abnormal vaginal discharge, which may be watery, creamy, or slightly green.
• Painful urination: Burning or pain during urination.
• Pelvic pain: Pain in the lower abdomen, especially during intercourse.
• Irregular menstrual bleeding: Bleeding between periods or after intercourse.

Symptoms in Other Areas

• Rectal infection: Anal itching, soreness, bleeding, or painful bowel movements.
• Throat infection (pharyngeal gonorrhea): Sore throat or swollen lymph nodes in the neck.
• Eye infection (gonococcal conjunctivitis): Redness, pain, or discharge in one or both eyes.
• Disseminated gonococcal infection (DGI): A rare but serious condition where the infection spreads to the bloodstream, causing fever, joint pain, or skin lesions.

Causes and Risk Factors

Gonorrhea is caused by the bacterium Neisseria gonorrhoeae, which is transmitted through sexual contact, including vaginal, anal, or oral sex. The bacteria can also be passed from an infected mother to her baby during childbirth.

Risk Factors

• Unprotected sex: Not using condoms or dental dams increases the risk of transmission.
• Multiple sexual partners: Having more than one sexual partner or a partner with multiple partners.
• Young age: Gonorrhea is most common in people under 25, particularly teenagers.
• Previous STIs: A history of other STIs, such as chlamydia, increases susceptibility.
• Drug use: Illicit drug use, particularly injection drug use, is associated with higher risk.
• Men who have sex with men (MSM): This group has a higher prevalence of gonorrhea.

Diagnosis

Gonorrhea is diagnosed through laboratory tests that detect the presence of Neisseria gonorrhoeae bacteria. Testing is crucial because many infected individuals do not show symptoms.

Diagnostic Tests

• Nucleic Acid Amplification Test (NAAT): This is the most common and reliable test. It detects the genetic material (DNA) of the gonorrhea bacteria in urine or swab samples from the urethra, cervix, rectum, or throat.
• Gram stain: A quick test that examines a sample of discharge under a microscope. It is more accurate for men with symptoms than for women.
• Culture test: A swab sample is placed in a special medium to grow the bacteria. This test is less common but useful for detecting antibiotic resistance.

The CDC recommends annual gonorrhea screening for:

• Sexually active women under 25.
• Women over 25 with risk factors (e.g., new or multiple partners).
• Men who have sex with men (MSM).
• People with HIV.

Treatment Options

Gonorrhea is treatable with antibiotics, but the rise of antibiotic-resistant strains has made treatment more challenging. The CDC recommends a dual therapy approach to combat resistance.

Antibiotic Treatment

• Ceftriaxone (Rocephin): A single intramuscular injection of 500 mg. This is the first-line treatment for gonorrhea.
• Azithromycin (Zithromax): A single oral dose of 1 gram, often given in combination with ceftriaxone to treat potential co-infections like chlamydia.

If you are allergic to cephalosporins (like ceftriaxone), your doctor may prescribe alternative antibiotics such as gentamicin or gemifloxacin.

Follow-Up

• Return for a follow-up test 7–14 days after treatment to ensure the infection is cured.
• Avoid sexual activity for at least 7 days after completing treatment.
• Notify all recent sexual partners (within the past 60 days) so they can be tested and treated.

Lifestyle Changes

• Abstain from sex: Until treatment is complete and the infection is cured.
• Use condoms: Consistently and correctly to prevent reinfection.
• Limit sexual partners: Reduce the number of partners to lower risk.

Living with Gonorrhea

If you are diagnosed with gonorrhea, taking steps to manage the infection and prevent complications is essential.

Daily Management Tips

• Complete the full course of antibiotics: Even if symptoms improve, finish all medication to ensure the infection is fully treated.
• Avoid alcohol: Alcohol can interfere with certain antibiotics.
• Stay hydrated: Drink plenty of water to help flush out the bacteria.
• Practice safe sex: Use condoms or dental dams during all sexual activities.
• Communicate with partners: Inform current and recent partners about the infection so they can seek testing and treatment.

Prevention

Preventing gonorrhea involves practicing safe sex and taking precautions to reduce exposure to the bacteria.

Prevention Strategies

• Use condoms: Latex or polyurethane condoms can significantly reduce the risk of transmission during vaginal, anal, or oral sex.
• Limit sexual partners: Having fewer sexual partners reduces the risk of exposure.
• Get regular screenings: If you are sexually active, especially with multiple partners, get tested for STIs regularly.
• Avoid sex with infected partners: If your partner has gonorrhea, avoid sexual contact until they have completed treatment.
• Consider mutual monogamy: Being in a long-term, mutually monogamous relationship with an uninfected partner lowers risk.
• Vaccination: While there is no vaccine for gonorrhea, staying up-to-date on other vaccines (e.g., HPV, hepatitis B) can protect overall sexual health.

Complications

If left untreated, gonorrhea can lead to serious and sometimes irreversible health complications.

Complications in Women

• Pelvic inflammatory disease (PID): An infection of the uterus and fallopian tubes that can cause chronic pelvic pain, ectopic pregnancy, or infertility.
• Ectopic pregnancy: A life-threatening condition where a fertilized egg implants outside the uterus, often in a fallopian tube.
• Infertility: Scarring of the fallopian tubes can prevent pregnancy.

Complications in Men

• Epididymitis: Inflammation of the epididymis (a tube near the testicles), which can lead to infertility if untreated.
• Prostatitis: Infection of the prostate gland, causing pain and urinary issues.

Complications in Both Sexes

• Disseminated gonococcal infection (DGI): A rare but serious condition where the bacteria enter the bloodstream, causing joint pain, skin lesions, or even life-threatening infections like meningitis or endocarditis.
• Increased HIV risk: Gonorrhea increases the risk of acquiring or transmitting HIV.
• Reactive arthritis: A type of arthritis that develops in response to the infection, causing joint pain and swelling.

Complications in Newborns

Babies born to mothers with untreated gonorrhea can develop:

• Gonococcal conjunctivitis (ophthalmia neonatorum): A severe eye infection that can lead to blindness if not treated promptly.
• Scalp infections: If the infection spreads during delivery.
• Bloodstream infections: Which can be life-threatening.
