An ovarian cyst consists of a closed structure that looks like a sac. These may form either within the ovary or on the ovary. The cyst typically contains a semisolid or liquid substance. A cyst is a generic term for the fluid-filled structure.
The cyst may or may not be a neoplasm or a tumor. If it is determined to be a tumor it may be malignant or benign. There are many different types of cysts that may form on or within the ovaries. The cause of these cysts will vary based on the type. In addition, most cysts that form will not cause any issues and are often simply dissolved within the body after a couple of months or so. However, there are some cysts that can cause health issues, especially if they rupture. Here are some of the most common causes of ovarian cysts to consider based on the type of cyst that it is.
1. Functional Cysts
The most common type of ovarian cyst is a functional cyst. A functional cyst is related to variations to the normal function of the ovaries. Functional cysts form when an egg is released during normal ovulation. This type of cyst will typically not secrete any hormones. Most of the time a functional cyst will not cause any type of symptoms in a woman who develops them.
Typically a functional cyst will last anywhere from four to six weeks and then will simply go away on their own. The main reason that these types of cysts are called functional ovarian cysts is that they actually serve a purpose. During menstruation, eggs start to mature.
During the first couple of weeks after your period, small cysts start to grow. While there are several of these cysts that grow, only one or two will be mature enough for ovulation. Once the rest of the cysts reach a certain size they will rupture.
