what causes bartholin cyst
A Bartholin cyst is usually caused by a tiny blockage in the duct of the Bartholin gland, which sits just inside the vaginal opening on each side. When that duct is blocked, the normal lubricating fluid can’t drain, so it backs up and forms a fluid‑filled lump (the cyst).
Quick Scoop: What causes a Bartholin cyst?
Think of the Bartholin gland duct like a small drain: if it gets clogged, fluid builds up behind it and makes a little “balloon” under the skin.
Main direct cause
- Blocked duct of the Bartholin gland – this is the core mechanism in almost all Bartholin cysts.
- The blocked duct stops normal gland secretions from coming out, so fluid accumulates and creates a soft, usually painless swelling at first.
What can block the duct?
Several things can irritate, injure, or narrow the duct and trigger that blockage:
- Minor injury or trauma
- Friction or minor trauma to the vulva area (e.g., intercourse, cycling, tight clothing) can sometimes irritate the duct opening.
* Injury during **childbirth** or procedures around the vulva can also cause scarring that narrows or closes the duct.
- Infection and inflammation
- Common skin bacteria like Escherichia coli (E. coli) and Staphylococcus can inflame the duct and lead to blockage.
* Sexually transmitted infections (STIs) such as **gonorrhea** and **chlamydia** can infect the area, causing swelling and obstruction of the duct.
* Once the duct is blocked, the trapped fluid itself can become infected and turn the cyst into a painful **abscess** (a pocket of pus).
- Skin changes and scarring
- Extra growth of skin or changes in the tissue around the duct opening may partially cover or close the duct, acting like a “flap” over the drain.
* Scarring after surgery or prior infections can narrow the duct, making it easier for fluid to get trapped again.
Why some people get them more than others
- Doctors don’t fully know why some people are prone to Bartholin cysts and others never get them.
- Known risk patterns include:
- Being in your 20s–30s (when glands are more active).
* Being **sexually active** , which can increase small irritations and risk of infections.
* Having had a **Bartholin cyst before** – once you’ve had one, the duct may remain a bit vulnerable to re‑blocking.
Often, no single clear trigger is ever found; many cases are simply recorded as “no known cause,” beyond the fact that the duct somehow got blocked.
Is a Bartholin cyst always from an infection?
- The cyst itself is usually not caused by infection at the start – it begins as a sterile fluid build‑up from blockage.
- It can later become infected , which is when it turns into a very painful, red, warm abscess that may need drainage and antibiotics.
Real‑life style example
Someone might notice a small, painless lump on one side of the vaginal opening after a few days of more intense activity or intercourse, but no major incident. Over time, the tiny duct likely got irritated or slightly injured, blocked off, and the gland’s lubrication fluid slowly collected there until it formed a cyst.
If you have a lump, pain, or swelling in that area, especially if it’s hot, very tender, or you have a fever, it’s important to see a doctor or gynecologist for proper diagnosis and treatment, since other conditions can look similar.
