Ovarian cysts are fluid-filled sacs that develop in a woman’s ovaries. There are several types of ovarian cysts, each with different characteristics and potential complications.
Follicular cysts: These are the most common type of ovarian cysts and develop when a follicle (a small sac containing an egg) fails to rupture during ovulation. They usually resolve on their own within one to three months and rarely cause any symptoms.
Corpus luteum cysts: These cysts form after ovulation, when the follicle that releases the egg becomes the corpus luteum, which produces progesterone. If the follicle does not shrink as it should, it can fill with fluid and become a cyst. Most of these cysts are harmless and resolve on their own within a few weeks.
Dermoid cysts: These cysts are made up of different types of tissue, including hair, skin, and teeth. They can grow large and may need to be surgically removed.
Endometriomas: These cysts form when the tissue that lines the uterus (endometrium) grows outside of the uterus and attaches to the ovary. They are often associated with endometriosis and can cause pain and discomfort.
Cystadenomas: These cysts develop from the cells that cover the outer surface of the ovary. They can grow very large and may need to be surgically removed.
Polycystic ovary syndrome (PCOS): This is a hormonal disorder that causes small cysts to form on the ovaries. Women with PCOS often have irregular periods, weight gain, and acne.
Symptoms of ovarian cysts can vary depending on the type and size of the cyst. Some women may not experience any symptoms at all, while others may have:
Pain or discomfort in the abdomen or pelvis
Bloating or swelling in the abdomen
Pain during sex
Irregular periods
Painful periods
Difficulty emptying the bladder
Constipation or frequent urination
Nausea or vomiting
If you experience any of these symptoms, it’s important to see your healthcare provider for an evaluation. Most ovarian cysts are benign and can be monitored with regular ultrasounds. However, some cysts may require surgery to remove, especially if they are causing significant pain or are at risk of rupturing.
