To fully understand ovarian cysts causes, it is important to know that there are a variety of different types of cyst that can form on the ovaries. Some are minor and clear up on their own, while others are more serious and require medical attention, perhaps resulting in surgery. There are a range of methods that can help eradicate and control ovarian cysts.
The basic type of cyst forms during menstruation. Small structures form on the ovaries called follicles, produce the hormones estrogen and progesterone and release an egg when a woman ovulates. Occasionally, these small structures continue to grow and form cysts. These are known as functional cysts, because they are due to the normal monthly cycle. The two types of functional cyst, are the follicular ovarian cyst and the corpus luteum ovarian cyst.
The first is formed if the small structure holding the egg does not release it, and it basically turns into a cyst. It is generally not painful, and disappears after a cycle or two. This is the most common type of cyst.
The latter maybe formed once the egg has left and its escape hole is somehow sealed and tissues collect and turn into a cyst. This type can be quite painful and the cyst could grow as big as 100cm and cause problems such as internal bleeding and twisting the ovary.
Another type of cyst, the dermoid cyst is formed on the ovaries. These are formed by mature skin, tissues and the like. These are almost always benign, ie non cancerous.
Another ovarian cysts causes are polycystic ovary syndrome (PCOS) is an increasingly diagnosed syndrome, which currently is not 100% known how this is caused. Insulin resistance, hyperglycaemia, diabetes and obesity have all been linked with it. It is interesting to note that the cases of PCOS has dramatically increased in the past 30 years, perhaps in a similar way to the amount of obesity and poor dietary foods have also increased in the same time span.
In very simple terms, because the body is so out of balance, the right hormones are not being released at the appropriate times, so the egg does not get released. This turns into a cyst and over time, more form and thickens the walls of the ovary and cause it to enlarge. This then causes infertility as one of the many symptoms of PCOS. Other symptoms include excess hair, abdomen, back & thigh pain and acne.
So you can see, there are various ovarian cysts causes, and various types of ovarian cyst too.
