A ruptured ovarian cyst is a cyst that breaks open. A cyst is a sac that grows on an ovary. This sac usually contains fluid, but may sometimes have blood or tissue in it. A large cyst that ruptures may lead to problems that need immediate care.
What causes or increases my risk for a ruptured ovarian cyst?
You may be at higher risk for a ruptured ovarian cyst if you have polycystic ovarian syndrome (PCOS). PCOS causes many cysts to grow on your ovary. Any of the following can lead to a ruptured cyst:
Hormone changes around the time of your monthly period
Pressure on the cyst from sports, sex, or an injury to the area (usually large cysts)
Pregnancy
