What are Sexually Transmitted Infections (STIs)?
Sexually transmitted infections (STIs) are infections that spread primarily through sexual contact.
There are different types of sexually transmitted diseases, including:
How do sexually transmitted diseases spread?
“Sexual contact” may sound a bit vague as a route of transmission. So what does it mean?
Sexual contact includes vaginal, anal, and oral sex, as well as the sharing of unsterilized sex toys—basically any instance in which an infected body fluid, such as semen or vaginal fluid, comes into contact with a mucous membrane, such as in the genitals, eyes, rectum, or throat.
However, sexual contact is not the only way to get a sexually transmitted disease.
Some sexually transmitted diseases such as syphilis, herpes and HPV can be transmitted through skin-to-skin contact. Other infections, such as hepatitis and HIV, can be spread through sharing needles and razors and through poorly tested blood transfusions.
In rare cases, gonorrhea infections of the throat have also been triggered through deep kissing.
It’s important to remember that if you are sexually active, you should protect yourself by practicing safe sex and getting tested regularly. Many sexually transmitted diseases do not initially cause any noticeable symptoms, but can still lead to complications. You should also use barrier protection during sexual activity to prevent the spread of infection.
What sexually transmitted diseases cause green discharge from the genitals?
Green discharge from the genitals is typically caused by four infections: chlamydia, gonorrhea, trichomonas and bacterial vaginosis.
Chlamydia
Chlamydia is an infection caused by the bacterium Chlamydia trachomatis. It is the most common bacterial STI particularly common in sexually active young people. Most genital chlamydia infections are transmitted through unprotected sexual intercourse.
Chlamydia often does not cause any symptoms. However, if symptoms do occur, they may include:
- Unusual penile and vaginal discharge that may be yellowish or green in color
- Burning, itching and irritation in the genital area
- Painful urination
- Pain during sexual intercourse
- Women experience pelvic pain and bleeding between periods
While chlamydia is most commonly found in the genitals, it can also infect the rectum and mouth. Contrary to some popular myths, You can’t get chlamydia from kissing.
gonorrhea
Gonorrhea is another bacterial infection caused by the bacterium Neisseria gonorrhoeae. Gonorrhea is highly contagious and can affect the genitals, mouth, eyes, and rectum.
Like chlamydia, gonorrhea often causes no symptoms, so it’s possible to have it without knowing it. However, if symptoms do occur, gonorrhea symptoms may appear within two to five days of exposure. These can include:
- Burning feeling when urinating
- Pain during sex
- Unusual vaginal bleeding
- Painful bowel movements (rectal infection)
The abnormal discharge caused by gonorrhea often occurs:
- A yellow or greenish discharge from your vagina or penis
- Thick, sticky and pus-like
- Abundant, often stained on underwear
- In women: Heavier than normal discharge and occasional bleeding between periods
Yellow/greenish penile or vaginal discharge is most commonly caused by a gonorrhea infection and requires antibiotics.
Trichomonas
Trichomonas is caused by a parasite called Trichomonas vaginaliswhich infects the urethra. Other urethral diseases can also cause similar symptoms.
Trichomonas can also occur without symptoms. However, when they do appear, they can include:
- Pain during sex
- Painful urination
- Increased urination
- Redness and swelling of the tip of the penis and/or foreskin
- Redness and itching of the vulva or vagina
The unusual discharge caused by Trichomonas will be:
- In the color white, green or yellow
- Thin
- Foamy
- “Fishy” smell
Bacterial vaginosis
Bacterial vaginosis, also called BV, is often caused by the overgrowth of a bacteria Gardnerella vaginaliswhich is naturally located in the vagina. BV is more common in sexually active women, but can often be caused by poor hygiene or the use of certain hygiene products such as soaps. BV can also increase your risk of getting other sexually transmitted diseases.
Men are less likely to become infected with BV because BV occurs naturally in the female genitals. However, the bacteria that cause BV can be passed from women to men during sex. Men colonized by these bacteria usually experience no symptoms other than occasional irritation and inflammation.
When BV occurs in women, it often causes:
- Vaginal redness
- pain
- itching
- combustion
BV can also cause a discharge that looks like this:
- Green, gray or cream
- Thin
- Cloudy
- “Unusual” smell
What does green discharge consist of?
Green discharge from the genitals is typically a mixture of pus, blood, and other body fluids. This is often accompanied by a strange smell. It can be thick and sticky or thin and watery.
How are sexually transmitted diseases that cause green discharge treated?
Most of the infections mentioned above are bacterial or parasitic infections. Therefore, they can be treated with a wide range of medications – usually antibiotics. However, treatment depends on the underlying cause. It is important to take all your medications as prescribed and to avoid sexual contact during treatment. If an STI is diagnosed, sexual partners should also be tested and treated.
