Ovarian cysts are sacs filled with fluid or semisolid material that form on or within one or both ovaries. There are several types of ovarian cysts, but the most common type is functional cysts, which occur as a result of ovulation. Other causes of ovarian cysts include:
- Hormonal problems: These include taking a fertility drug that causes you to ovulate, for example, clomiphene or letrozole (Femara) .
- Endometriosis: This is a condition where tissue similar to the lining of the womb grows in other places, such as the ovaries and fallopian tubes.
- Pregnancy: Sometimes, the follicle that forms when you ovulate stays on your ovary throughout pregnancy. It can sometimes grow larger.
- Severe pelvic infection: If the infection spreads to the ovaries, it can cause cysts.
- Previous ovarian cysts: If youve had one ovarian cyst, youre likely to develop more.
Most ovarian cysts cause no symptoms and go away on their own. However, a large ovarian cyst can cause symptoms such as sudden and severe pelvic pain, abdominal swelling, or a feeling of fullness or pressure. In rare cases, ovarian cysts can cause complications that require medical attention, such as torsion or twisting of the ovary on its blood supply, or rupture of a cyst with internal bleeding. If you experience any symptoms of ovarian cysts, it is important to see a healthcare provider for evaluation and treatment.
