Just as there are many different forms of ovarian cysts, there are also a multitude of causes for them as well. Having a good understanding of the factors that trigger ovarian cysts is vital. Without this knowledge, it's not always possible to get the correct treatment.

The most common type of ovarian cyst is the functional cyst. The functional cyst occurs when the normal sequence of events of the menstrual cycle fail in some way. Normally, small structures called follicles grow inside of your ovaries. Each of these follicles contain one egg and is supposed to make the hormones estrogen and progesterone.

Halfway through the menstrual cycle, the pituitary gland normally signals the follicle to rupture and release the egg. After the egg is released, the hormones estrogen and progesterone are produced by the ruptured follicle.

There are two modes or ways that this sequence gets disrupted. This causes two different sorts of functional cysts:

1.) Follicular cyst.

If the egg isn't released by the follicle, then the follicle becomes a follicular cyst. Normally they're harmless and will disappear after two or three menstrual cycles.

2.) Corpus luteum cyst.

If the follicle ruptures and releases the egg, but closes up instead of remaining open, it will swell up with liquid and becomes a corpus luteum cyst. It normally vanishes in a few weeks time. Problems can arise however, such as growing very large, filing up with blood, rupturing, or getting twisted. These complications can lead to pelvic or abdominal pain which can become sharp and intense if the cyst ruptures.

In either case, the follicle doesn't release progesterone, resulting in a hormonal imbalance. The imbalance causes the growth of more cysts.

Factors that exert a powerful influence on ovarian cyst growth are:

1.) Genetics - If your mother or a sister has ovarian cysts, you have a higher chance of having it yourself. Research has shown that there is a genetic difference between those who are prone to ovarian cysts and those who aren't.

2.) Insulin resistance - Insulin resistance causes excessive insulin levels in the blood. This causes the ovaries to produce too much androgens (male hormones) which can cause the development polycystic ovarian syndrome (PCOS).

3.) Weak immune system - A strong immune system readily destroys foreign substances and cells in the body. It also destroys abnormal cells and other agents that trigger ovarian cysts.

4.) Poor diet - If you don't give the body what it needs, it will not function properly. Among the multitude of problems caused by a poor diet are a weakened immune system and a hormonal imbalance. Both of these conditions promote the growth of ovarian cysts. We all have a good idea of what constitutes a poor diet. Too much junk food and carbohydrates, and too little of the essential nutrient rich foods such as fresh vegetables.

Regular checkups and consultations with your doctor are essential. However, some of the causes of ovarian cysts listed above are strongly influenced by lifestyle choices.
