What Are Ovarian Cysts? A Patient's Guide to the Condition

Ovarian cysts are fluid-filled sacs that develop on or inside an ovary. They are quite common and often form during the menstrual cycle. While many ovarian cysts are harmless and go away on their own, some can cause symptoms or lead to complications. Understanding what ovarian cysts are and how they affect your health can help you make informed decisions about your care.

What are ovarian cysts?

Ovarian cysts are sacs filled with fluid that can form in or on an ovary. The ovaries are part of the female reproductive system and are responsible for producing eggs and hormones like estrogen and progesterone. Most ovarian cysts are functional cysts, which means they form as part of the normal menstrual cycle. These include follicular cysts and corpus luteum cysts. Follicular cysts occur when a follicle (a small sac that contains an egg) doesn't release the egg as it should, while corpus luteum cysts form when the follicle releases the egg but doesn't shrink back down.

Why do ovarian cysts matter?

While many ovarian cysts are benign (non-cancerous) and resolve without treatment, some can cause symptoms such as pelvic pain, bloating, or irregular menstrual cycles. In rare cases, cysts can lead to complications like ovarian torsion, where the ovary twists around the ligaments that hold it in place, or rupture, which can cause severe pain and internal bleeding. Additionally, some cysts can indicate underlying conditions such as polycystic ovary syndrome (PCOS) or endometriosis, which may require further evaluation and treatment.

What causes ovarian cysts?

The majority of ovarian cysts are caused by hormonal changes during the menstrual cycle. However, other factors can contribute to their development, including hormonal imbalances, pregnancy, severe pelvic infections, and conditions like PCOS and endometriosis. It is important to note that having an ovarian cyst does not necessarily mean there is a serious problem, but monitoring and evaluation by a healthcare provider can help ensure that any potential issues are addressed.

How are ovarian cysts diagnosed?

Ovarian cysts are often discovered during a routine pelvic examination or an ultrasound, which uses sound waves to create images of the ovaries. If a cyst is found, your doctor may recommend additional tests such as a blood test to check hormone levels or a CA-125 test if there is a concern about cancer. The CA-125 test measures the amount of a protein called cancer antigen 125 in the blood, which can be elevated in certain conditions, including ovarian cancer.

Treatment options for ovarian cysts

The treatment for ovarian cysts depends on several factors, including the size and type of the cyst, your age, and whether you have symptoms. In many cases, a "watchful waiting" approach is recommended, where the cyst is monitored with regular ultrasounds to see if it changes or resolves on its own. If treatment is necessary, options may include hormonal birth control to prevent new cysts from forming, or surgery to remove the cyst if it is large, persistent, or causing symptoms.

Frequently asked questions

What are the symptoms of an ovarian cyst? Ovarian cysts often do not cause symptoms, but when they do, they may include pelvic pain, bloating, painful periods, and pain during intercourse.

Can ovarian cysts affect fertility? Most ovarian cysts do not affect fertility. However, conditions like PCOS and endometriosis, which are associated with cysts, can influence fertility.

Are ovarian cysts cancerous? Most ovarian cysts are benign. However, some can be cancerous, especially in postmenopausal women. Regular monitoring can help detect any changes early.

Can ovarian cysts go away on their own? Yes, many ovarian cysts, especially functional cysts, can resolve on their own without treatment.

What should I do if I suspect I have an ovarian cyst? If you experience symptoms like persistent pelvic pain or unusual menstrual changes, it is a good idea to consult a healthcare provider for evaluation.

When to see a doctor

You should see a doctor if you experience severe pelvic pain, sudden sharp abdominal pain, or symptoms like dizziness or fainting, as these could indicate a ruptured cyst or ovarian torsion. Additionally, if you have persistent symptoms like bloating, changes in menstrual cycles, or pain during intercourse, it is important to seek medical advice. Regular check-ups can help monitor any cysts and ensure that appropriate care is provided.
