Vaginal discharge is common for most women. While discharge may be slight at times, some women experience different discharge colors, such as green discharge, which we’ll be focusing on in this article.

In most cases, green colored discharge is a sign that there’s an internal problem.

The most common cause of green discharge is related to an STD known as trichomoniasis. While you may have never heard of this sexually-transmitted disease before, it’s actually quite common and occurs in more than 3 million people in the United States every single year.

What is Trichomoniasis?

Light green vaginal discharge is likely an indication of an STD. The STD may not even be trichomoniasis, but this is the most common cause of the discharge you’re experiencing. If you do have green vaignal discharge with no odor, it’s unlikely that trichomoniasis is the cause and you can skip ahead to the next section.

Trichomoniasis background, signs and symptoms.

Transmitted through intercourse, trichomoniasis is an infection caused by a parasite that enters into the body.

Oftentimes, people don’t even realize that they have this disease. In approximately 70% of all infected people, this STD will not present any signs or symptoms. While most people will experience symptoms within 5 to 28 days, others develop symptoms much later on.

For women, the following symptoms are experienced:

  • Vaginal itching
  • Vaginal burning
  • Vaginal redness or soreness
  • Discomfort when urinating

You may experience light green discharge, yellow green discharge or darker green discharge. If you’ve contracted this disease, you’ll notice a strange odor coming from your discharge. This is one of the first signs that you have this STD, and you’ll want to see your doctor as soon as possible to discuss your treatment options.

The good news is that trichomoniasis is a curable disease.

If your discharge is green, it may also be a sign of:

  • Gonorrhea
  • Bacterial vaginosis

Thankfully, in most cases, this green discharge is curable and not a sign of a life-threatening situation.

Green Discharge While Pregnant

Pregnancy causes so many changes in the body, and you’ll experience some very strange issues. Vaginal discharge will become a part of life, and will be an indicator of many different issues. When this discharge is green, it’s often caused by a urinary tract infection (UTI).

And UTIs are very common during pregnancy.

As the uterus expands, excess pressure is put on the uterus itself. What this pressure does is restricts the flow of urine. As a result, the bladder fills up excessively, causing the massive urgency to run to the bathroom as every woman experiences during pregnancy.

Many women will also try to hold all of their urine in at this time, increasing the likelihood of an infection occurring.

Bacteria will begin to develop in the urinary tract and eventually lead to a UTI. A UTI can be the cause behind your green discharge.

Of course, it’s important to talk to your medical doctor if you’re experiencing this type of discharge to make sure that you don’t have an STD. An STD can cause birth complications and may harm the baby. Always contact your medical professional at this time unless you’ve been tested and have not had intercourse since your last test.

In this case, it’s likely a urinary tract infection, which can easily be treated with antibiotics.

Pregnancy can complicate the treatments your doctor recommends. If you’re pregnant and don’t want to take an antibiotic for your UTI or STD, you will need to discuss your options with your physician. A UTI may heal itself over time, but an STD will likely require an antibiotic to correct the issue.

Green Discharge from Eyes

Women who are pregnant will also want to be cautious of green discharge coming from their eyes. This isn’t caused by the pregnancy itself, but is a sign of a deeper medical issue that will need to be examined.

The most common causes for green or yellow discharge from the eyes include:

  • Stye
  • Meibomian cyst
  • Dacryocystitis

You may also be suffering from several forms of conjunctivitis, including:

  • Allergic
  • Bacterial
  • Chlamydial
  • Viral

In all of these instances, you’ll want to seek the assistance of a medical professional to be properly diagnosed. For most women, conjunctivitis is the cause, which is easily treated with medicated eye drops.

Many women suffer from green vaginal discharge, and the color can be yellowish as well as green. It’s important to pay attention to the discharge you’re experiencing as it may be a sign of an STD or infection. Always discuss any strange discharge colors or textures with your doctor to ensure that your baby is healthy and protected.

When in doubt, always ask your medical professional to conduct tests to determine the cause of your green discharge. But in most cases, this type of discharge is not a cause for concern and will easily be remedied with a prescription.
