What Causes Ovarian Cysts?

The causes of ovarian cysts are many. Each month during the menstrual cycle the ovaries normally develop follicles, which are cysts like in structure. Estrogen and progesterone hormones are produced by these follicles, which are necessary for pregnancy. If the follicles stay and continue to grow over a length of time an ovarian cyst can develop.

The causes of ovarian cysts are many. Each month during the menstrual cycle the ovaries normally develop follicles, which are cysts like in structure. Estrogen and progesterone hormones are produced by these follicles, which are necessary for pregnancy. If the follicles stay and continue to grow over a length of time an ovarian cyst can develop.

Follicular cysts are the most common type of cysts. They are usually harmless, rarely cause any symptoms and usually disappear on their own. Normal causes of ovarian cysts affecting the follicles take place when the pituitary gland releases hormones to trigger the release of an egg which in fact does not occur. Instead, the follicle continues to grow and develops into a cyst.

Frequent causes of ovarian cysts occur when luteinizing hormones surge and an egg is release. When the egg is released, estrogen and progesterone are created by the ruptured follicle to prepare for the hypothetical conception. When the egg is sealed off, fluid accumulates inside the follicle and becomes what is called a corpus luteum. The corpus luteum will then expand and at that point becomes a cyst.

A corpus luteum cyst will typically disappear on its own without any treatment, although it could grow to 4 inches in diameter during just a period of a few weeks. It could also bleed internally or twist an ovary. If the corpus luteum cyst ruptures this can cause internal bleeding, in addition to sudden sharp or severe pain.

The drug clomiphene citrate is a fertility drug that works to induce ovulation, and might in itself, be among the causes of ovarian cysts. Clomiphene citrate is in fact known to increase the risk of developing a corpus luteum cyst (which does not prevent or threaten pregnancy), and therefore probably causes other cysts as well.

A cyst that contains blood is classified as a hemorrhagic or endometrioid cyst. These cysts develop like other cysts, only that they contain blood. The presence of blood could be due to and injury or from the surrounding blood vessels leaking through into the egg sac. Endometrioid cysts are caused by the bleeding and shedding of endometrioid tissue embedding itself into the ovaries. The build up of blood will eventually rupture, causing severe pelvic pain.

The actual causes of ovarian cysts occurring can't be prevented, but there are certain steps you can take to decrease the possibility of them developing. The most important steps you can do, but not limited to, is to improve your overall health. Easting healthier, getting more exercise, controlling stress and remembering to take time out for yourself to relax. Plus regular checkups with your doctor call all help to reduce the chances of developing ovarian cysts.
