Not every chocolate cyst causes pain immediately or in the initial stages, but that doesn’t mean it’s safe to neglect. These cysts keep growing silently, overstretch your ovaries, and are filled with thick, trapped menstrual blood. Over time, they exert pressure on the nearby organs, twist the ovary, or even burst, causing sharp pain, internal bleeding, or infection.
Along with the physical health risks, untreated chocolate cysts can also affect your daily life, interrupting sleep, intimacy, periods, and even your chances of conceiving. You may feel fatigue all the time, or anxious about the next flare-up.
Getting timely treatment for chocolate cyst keeps away complications and allows you to have better control over your reproductive health and your future. For safe and effective treatment from expert gynecologists in Chennai, contact Pristyn Care.
No, chocolate cysts don’t form normally in the body. This type of ovarian cyst is linked with endometriosis and causes pain, irregular periods, or infertility symptoms. Early diagnosis is important to avoid complications.
Surgery becomes necessary if the cyst is larger than 4–5 cm, is painful, or is growing larger. The decision also depends on your symptoms, age, and whether you’re planning a pregnancy.
Yes, it is possible to get pregnant with a chocolate cyst, especially if it’s small and is affecting only one ovary. However, larger cysts or those located on both ovaries can affect fertility by impairing ovulation and egg quality. It’s best to consult a gynecologist early if you’re trying to get pregnant.
The discharge from a chocolate cyst is usually thick, dark brown, and looks like old blood, thus the name “chocolate” cyst. This fluid is rarely seen outside the body unless the cyst ruptures or is drained during surgery.
