Ovarian cysts are a common occurrence in women and can develop on or inside the ovaries. While most cysts are harmless and often go away on their own without causing any symptoms, there are cases where they can lead to complications. In this comprehensive guide, we will explore the different types of ovarian cysts, their causes, symptoms, diagnosis, treatment options, and outlook. We’ll also address the question of whether ovarian cysts are dangerous and discuss how to manage and prevent them.

Overview of ovarian cysts

What are ovarian cysts?

Ovarian cysts are fluid-filled sacs that develop either on or inside the ovaries. The ovaries, part of the female reproductive system, play a crucial role in the menstrual cycle and hormone production. Most ovarian cysts are benign and painless, often resolving on their own without any medical intervention. However, understanding the different types of ovarian cysts is essential for accurate diagnosis and appropriate treatment.

Types of ovarian cysts

There are two main types of ovarian cysts: functional and pathological cysts.

Functional cysts are the most common type and develop as a normal part of the menstrual cycle. They occur when the follicles in the ovaries fail to release an egg or when the corpus luteum, which forms after the egg is released, fills with fluid. Examples of functional cysts include follicular cysts and corpus luteum cysts.

Pathological cysts, on the other hand, form as a result of abnormal cell growth. They are less common and can be caused by conditions such as endometriosis. Pathological cysts include cystadenomas, dermoid cysts, endometriomas, and ovarian cancer cysts.

Prevalence of ovarian cysts

Ovarian cysts are extremely common, especially in premenopausal women. In fact, functional cysts are a natural occurrence during the menstrual cycle. It is estimated that up to 8 out of 10 women will develop an ovarian cyst at some point in their lives. Most of these cysts are harmless and resolve on their own without causing any symptoms or complications.

Causes of ovarian cysts

Functional ovarian cysts

Functional ovarian cysts develop as part of the normal menstrual cycle. The two main types of functional cysts are:

  • Follicular cysts: These cysts occur when a follicle fails to release an egg during ovulation. Instead, the follicle fills with fluid and grows larger
  • Corpus luteum cysts: After the follicle releases an egg, it forms a structure called the corpus luteum. If fluid accumulates in the corpus luteum, a cyst can form

These functional cysts are usually harmless and resolve on their own within a few months.

Pathological ovarian cysts

Pathological ovarian cysts are less common and can be caused by various factors, including:

  • Abnormal cell growth: Atypical cell reproduction can lead to the formation of cysts such as dermoid cysts and cystadenomas
  • Endometriosis: In advanced stages of endometriosis, cysts called endometriomas can develop on the ovaries
  • Pelvic inflammatory disease (PID): Severe pelvic infections can spread to the ovaries, resulting in the formation of cysts

It’s important to note that while most ovarian cysts are benign, there is a small chance of them being cancerous. Ovarian cancer cysts are solid masses of cancer cells and require immediate medical attention.

Underlying conditions

Certain factors and medical conditions can increase the risk of developing ovarian cysts. These include:

  • Age: Ovarian cysts are more common in premenopausal women
  • Pregnancy status: Cysts are more likely to form and persist during pregnancy
  • History of ovarian cysts: If you’ve had an ovarian cyst before, you may be more prone to developing another one
  • Current medical conditions: Conditions such as endometriosis, polycystic ovary syndrome (PCOS), hormonal problems, and the use of ovulation-inducing medications like Clomid can increase the likelihood of ovarian cysts

Symptoms of an ovarian cyst

When do ovarian cysts cause symptoms?

In many cases, ovarian cysts do not cause any symptoms and are discovered incidentally during routine pelvic exams or imaging procedures. However, certain factors can lead to the manifestation of symptoms, including the size of the cyst, its location, and the presence of complications.

Common symptoms of ovarian cysts

When symptoms do occur, they can vary in intensity and may include:

  • Pelvic pain: This can range from a dull, heavy sensation to sudden, severe, and sharp pain
  • Pain during intercourse: Some women may experience discomfort or pain during sexual intercourse
  • Bowel and bladder issues: Ovarian cysts can put pressure on the bladder or bowel, causing difficulty with urination or bowel movements
  • Menstrual irregularities: Cysts can disrupt the normal menstrual cycle, leading to heavy, irregular, or lighter-than-normal periods
  • Bloating and abdominal swelling: Some women may experience bloating and a swollen abdomen
  • Feeling full quickly: Ovarian cysts can cause early satiety, making you feel full after consuming only a small amount of food

Signs of potential complications

While most ovarian cysts are harmless, certain symptoms may indicate potential complications that require immediate medical attention. These include:

  • Sudden, severe pelvic pain
  • Abdominal pain accompanied by nausea or vomiting
  • Light-headedness, rapid breathing, and cold, clammy skin

If you experience any of these symptoms that may indicate a ruptured ovarian cyst, it is important to seek medical assistance promptly.

Diagnosing ovarian cysts

Medical history and physical examination

If you’re experiencing symptoms that may be indicative of ovarian cysts, your healthcare provider will begin by taking a detailed medical history and performing a physical examination. During the physical examination, your provider may feel your pelvis for any abnormalities or signs of cysts.

Imaging tests

To confirm the presence of an ovarian cyst and gather more information about its characteristics, your provider may recommend imaging tests such as:

  • Ultrasound scan: This imaging procedure uses sound waves to create detailed images of your ovaries. It can help determine the size, location, and composition of the cyst
  • MRI (Magnetic Resonance Imaging): In some cases, MRI’s may be used to provide more detailed images of the cyst and surrounding tissues

Blood tests

Blood tests may be ordered to assess certain markers that could indicate the presence of ovarian cancer. These tests measure levels of specific chemicals in the blood, such as CA-125. However, it’s important to note that elevated levels of these markers do not necessarily mean you have ovarian cancer, as they can also be caused by non-cancerous conditions like endometriosis or pelvic infections.

Treatment options for ovarian cysts

Watchful waiting

In many cases, ovarian cysts do not require immediate treatment and may resolve on their own over time. Your healthcare provider may recommend a period of watchful waiting, where you will be monitored closely to ensure the cyst does not grow or cause complications. During this time, you may undergo periodic ultrasounds to track the cyst’s progress.


Certain medications may be prescribed to manage ovarian cysts, particularly those that are causing symptoms or are at risk of complications. Hormonal birth control pills can help regulate the menstrual cycle and prevent the formation of new cysts. Other medications, such as GnRH agonists, may be prescribed to suppress ovulation and reduce the size of existing cysts.

Surgical intervention

Surgery may be necessary if the cyst is large, causing severe symptoms, or suspected to be cancerous. The type of surgery will depend on the size and appearance of the cyst, as well as your overall health. Surgical options include:

  • Laparoscopy: A minimally invasive procedure where small incisions are made in the abdomen, allowing the surgeon to remove or drain the cyst
  • Laparotomy: In some cases, a larger incision may be required to remove the cyst, especially if it is large or deemed cancerous

If cancer is suspected, your healthcare provider may consult with a gynecological oncologist to determine the best course of treatment.

Managing ovarian cysts

Lifestyle changes

While lifestyle changes cannot prevent the development of ovarian cysts, they may help manage symptoms and reduce the risk of complications. Some strategies include:

  • Pain management: Over-the-counter pain relievers, such as ibuprofen, can help alleviate pelvic pain associated with ovarian cysts
  • Heat therapy: Applying a heating pad to the lower abdomen can help relieve discomfort and reduce muscle tension
  • Regular exercise: Engaging in regular physical activity can help promote overall pelvic health and alleviate symptoms
  • Healthy diet: Consuming a balanced diet rich in fruits, vegetables, and whole grains can support overall reproductive health

Regular check-ups and monitoring

After the diagnosis of an ovarian cyst, regular follow-up appointments are crucial to monitor the cyst’s progress and ensure it does not cause complications. Your healthcare provider may recommend periodic ultrasounds or other imaging tests to track the cyst’s size and characteristics. If any changes or concerns arise, further intervention may be necessary.

Prevention of ovarian cysts

Birth control options

Taking hormonal birth control, such as combined oral contraceptives or progestin-only pills, can help regulate the menstrual cycle and prevent the formation of functional cysts. Birth control options like the contraceptive patch, injections, or intrauterine devices (IUDs) may also be considered.

Awareness and early detection

While it may not be possible to prevent all ovarian cysts, being aware of your body and seeking prompt medical attention if you experience any symptoms is crucial. Regular pelvic exams and routine gynecological check-ups can help detect ovarian cysts early before they cause complications.

Are ovarian cysts dangerous?

Risks associated with ovarian cysts

In general, the majority of ovarian cysts are harmless and not dangerous. Most functional cysts resolve on their own without causing complications. However, there are some risks associated with ovarian cysts, including:

  • Rupture: Cysts can rupture, causing sudden and severe abdominal pain. While most ruptured cysts resolve on their own, some may require medical intervention
  • Ovarian torsion: In rare cases, a cyst can cause the ovary to twist, cutting off its blood supply. This can lead to intense pain and requires immediate medical attention
  • Cancerous cysts: While rare, some cysts can be cancerous. It’s important to monitor any changes in symptoms or characteristics of the cyst and seek medical advice promptly if there are concerns

Potential complications

Although most ovarian cysts are harmless, certain complications may arise, necessitating medical intervention. These include:

  • Hemorrhagic cysts: Cysts that contain blood can cause internal bleeding, leading to severe pain and potentially requiring surgical intervention
  • Infection: If a cyst becomes infected, it can cause fever, pain, and other signs of infection. Prompt medical treatment is necessary in such cases
  • Adhesions: Some ovarian cysts can lead to the formation of scar tissue, which may cause organs to stick together and result in chronic pain or fertility issues

It’s important to remember that the risk of complications is relatively low, and most ovarian cysts do not cause serious harm.

Ovarian cysts and fertility

Impact on fertility

In general, ovarian cysts do not significantly impact your fertility. Most functional cysts do not interfere with ovulation or the ability to conceive. However, certain factors, such as the underlying cause of the cyst or the need for surgical intervention, can affect fertility. It’s essential to discuss any concerns about fertility with your healthcare provider.

Preserving fertility during treatment

If surgical intervention is required to remove an ovarian cyst, your healthcare provider will aim to preserve fertility whenever possible. This may involve removing only the cyst while leaving the ovaries intact or removing only one ovary. In some cases, the removal of both ovaries may be necessary, which would result in the cessation of egg production. It’s important to have a thorough discussion with your surgeon about the potential impact on fertility before undergoing any procedures.

Support and resources

Seeking medical advice

If you’re experiencing symptoms or have concerns about ovarian cysts, it’s important to seek medical advice from a healthcare professional. Your primary care physician or a gynecologist can provide guidance, perform necessary tests, and develop a personalized treatment plan based on your unique circumstances.

Online resources and communities

There are various online resources and communities where you can find additional information and connect with others who have experienced ovarian cysts. Reputable sources, such as the NHS website and other medical websites, can provide reliable information to supplement your knowledge. However, it’s essential to use caution and consult with healthcare professionals for personalized advice.


Ovarian cysts are a common occurrence among women and are usually harmless, resolving on their own without causing any symptoms or complications. Understanding the different types of ovarian cysts, their causes, symptoms, and treatment options is crucial for accurate diagnosis and appropriate management. While most cysts do not pose a significant risk, it’s important to be aware of potential complications and seek medical help if any concerning symptoms arise. By staying informed and maintaining regular check-ups, you can effectively manage ovarian cysts and ensure your overall reproductive health.
