Ovarian Cysts: Types, Causes, Symptoms, Diagnosis and Treatment
Ovarian cysts are fluid-filled sacs that develop in or on the ovaries. They are common, and many are harmless, cause no symptoms, and resolve naturally without treatment. However, some cysts may cause pelvic pain, menstrual changes, or complications that require medical attention.
Understanding the different types of ovarian cysts, their causes, symptoms, and available treatment options can help women make informed decisions about their reproductive health. Depending on the cyst’s size, appearance, symptoms, and impact on fertility, management may involve monitoring, medication for associated conditions, or surgery.
What Are Ovarian Cysts?
Ovarian cysts are sacs filled with fluid or, in some cases, other material that form within or on an ovary. They may develop during the normal menstrual cycle or occur because of conditions such as endometriosis.
Many cysts are detected during routine gynaecological examinations or pelvic ultrasound scans. While most are non-cancerous, their management depends on factors such as the patient’s age, symptoms, menopausal status, and the cyst’s appearance on imaging.
Ovarian cysts do not always affect fertility. However, certain conditions associated with cysts, including endometriosis, may affect reproductive health. A gynaecologist can help determine whether a cyst needs treatment or simply monitoring.
What Are the Types of Ovarian Cysts?
Ovarian cysts can be classified into several types based on their cause and characteristics.
1. Functional Cysts
Functional cysts develop as part of the menstrual cycle and are among the most common types.
- Follicular cysts: Develop when a follicle does not release an egg or fails to shrink after the expected stage of ovulation.
- Corpus luteum cysts: Form when the structure left after ovulation accumulates fluid or blood.
These cysts often resolve on their own over several weeks or menstrual cycles.
2. Dermoid Cysts
Also known as mature cystic teratomas, dermoid cysts may contain tissues such as hair, skin, or teeth. They are generally benign but may require monitoring or removal depending on their size, symptoms, and risk of complications.
3. Endometriomas
Endometriomas are ovarian cysts associated with endometriosis, a condition in which tissue similar to the uterine lining grows outside the uterus. They may cause pelvic pain and can be associated with fertility difficulties.
Treatment decisions require particular care when pregnancy is a goal because some procedures to remove endometriomas may affect ovarian reserve.
4. Cystadenomas
Cystadenomas develop from cells on the surface of the ovary. They may contain watery or mucus-like fluid and can grow considerably in size. Their management depends on their appearance, size, symptoms, and the possibility of complications.
5. Polycystic Ovaries Associated With PCOS
Polycystic ovary syndrome (PCOS) is a hormonal condition that can affect ovulation and menstrual regularity. The term “polycystic ovaries” refers to the appearance of numerous small follicles on the ovaries; these are not the same as typical ovarian cysts.
Having polycystic-appearing ovaries alone does not necessarily mean a person has PCOS. Diagnosis depends on the overall clinical picture.
What Causes Ovarian Cysts?
Ovarian cysts can develop for different reasons, including:
- Normal ovulation: Changes during the menstrual cycle can lead to functional cysts.
- Hormonal factors: Hormonal changes may influence ovulation and cyst formation.
- PCOS: This condition can affect normal ovulation and menstrual cycles.
- Endometriosis: Endometrial-like tissue involving an ovary can form an endometrioma.
- Pregnancy: A corpus luteum cyst may develop in early pregnancy and often resolves naturally.
The cause cannot always be identified from symptoms alone. A medical assessment and, when appropriate, an ultrasound scan can help determine the likely type of cyst.
What Are the Symptoms of Ovarian Cysts?
Many ovarian cysts do not cause noticeable symptoms. When symptoms occur, they may vary depending on the cyst’s size, location, and type.
Common Symptoms
Possible symptoms include:
- Pelvic pain or discomfort, sometimes on one side
- A feeling of pressure or heaviness in the lower abdomen
- Abdominal bloating or swelling
- Pain during sexual intercourse
- Changes in menstrual patterns
- Frequent urination or pressure on the bladder, particularly with larger cysts
These symptoms can also occur with other medical conditions, so they do not confirm the presence of an ovarian cyst.
Warning Signs Requiring Urgent Medical Attention
Seek emergency medical care if you experience:
- Sudden, severe pelvic or lower abdominal pain
- Severe pain accompanied by nausea or vomiting
- Fainting, marked dizziness, or weakness
- Severe abdominal pain with signs of significant bleeding
These symptoms may indicate complications such as ovarian torsion, in which the ovary twists and its blood supply may be reduced, or a ruptured cyst with internal bleeding.
Other Possible Symptoms
Some people may experience fatigue, digestive discomfort, or breast tenderness. These symptoms are non-specific and may have causes unrelated to ovarian cysts.
Persistent or worsening symptoms should be evaluated by a healthcare professional.
What Are the Risk Factors and Complications of Ovarian Cysts?
Most ovarian cysts are benign and resolve without complications. However, certain cysts may require closer observation or treatment.
Potential complications include:
- Ovarian torsion: A cyst or enlarged ovary may increase the risk of twisting, potentially compromising the ovary’s blood supply.
- Cyst rupture: A cyst may break open, causing pain and, occasionally, significant internal bleeding.
- Pressure symptoms: Larger cysts may press on the bladder or bowel.
- Fertility-related concerns: Endometriomas and some underlying hormonal conditions may affect fertility, although many ovarian cysts do not.
- Possible malignancy: Most ovarian cysts are non-cancerous, but some complex masses require further assessment, particularly depending on age and menopausal status.
The risk of complications varies from person to person. Regular follow-up, when recommended, helps doctors monitor changes and decide whether treatment is necessary.
How Are Ovarian Cysts Diagnosed?
Diagnosis involves evaluating symptoms, medical history, and the cyst’s characteristics. Not every patient requires every test; investigations are selected according to individual circumstances.
1. Medical History and Pelvic Examination
A gynaecologist may ask about pelvic pain, menstrual cycles, pregnancy plans, previous ovarian conditions, and other symptoms. A pelvic examination may help identify tenderness or an abnormal mass, but it cannot reliably detect or classify every cyst.
2. Ultrasound Scan
Pelvic ultrasound is the main imaging test used to evaluate ovarian cysts. It helps assess their size, location, structure, and appearance.
A transvaginal ultrasound may provide a more detailed view of the ovaries when appropriate. The scan can help distinguish simple, fluid-filled cysts from cysts with more complex features and guide decisions about monitoring or further investigation.
3. Blood Tests
Blood tests may be recommended when the clinical assessment or ultrasound findings indicate a need for further evaluation.
- CA-125: This test may be used in selected cases to help assess the risk associated with a suspicious ovarian mass. It is not a definitive cancer test, and levels can also rise in non-cancerous conditions such as endometriosis.
- Hormonal tests: These may be useful when symptoms suggest PCOS or another hormonal condition affecting menstrual cycles or ovulation.
Not everyone with an ovarian cyst needs CA-125 or hormonal testing.
4. Laparoscopy
Laparoscopy is a minimally invasive surgical procedure involving small abdominal incisions and a camera. It may be recommended when surgery is needed to treat a cyst or when further assessment is necessary.
It is not routinely required to diagnose every ovarian cyst. The choice of procedure depends on the cyst’s characteristics, suspected diagnosis, symptoms, and the patient’s reproductive goals.
How Are Ovarian Cysts Treated?
Treatment depends on the cyst’s type, size, appearance, symptoms, and likelihood of resolving naturally. Age, menopausal status, and plans for pregnancy are also important considerations.
1. Watchful Waiting and Monitoring
Many simple functional cysts disappear without treatment. A doctor may recommend observation with a repeat ultrasound after an appropriate interval to check whether the cyst is shrinking, stable, or changing.
Not every cyst requires repeated scans. The follow-up schedule depends on the initial findings and the patient’s individual risk factors.
2. Medication and Hormonal Treatment
Medication may be prescribed to manage pain or treat an underlying condition. Hormonal contraceptives may help regulate menstrual cycles or reduce the formation of some new functional cysts in selected patients.
However, combined oral contraceptives generally do not make an existing functional ovarian cyst disappear faster. Hormonal treatment is not appropriate for every type of cyst, and its suitability depends on individual medical needs and pregnancy plans.
3. Surgical Removal
Surgery may be considered if a cyst is persistent, growing, large, causing significant symptoms, has concerning imaging features, or is associated with complications.
When appropriate, laparoscopy may allow a surgeon to remove the cyst through small incisions. In some situations, open surgery may be necessary. The surgical approach depends on the cyst’s size, characteristics, and the level of concern about malignancy.
When future pregnancy is important, the surgeon will consider ways to preserve healthy ovarian tissue whenever medically appropriate. Nevertheless, ovarian surgery can sometimes affect ovarian reserve, so its potential benefits and risks should be discussed beforehand.
4. Fertility Care When Ovarian Cysts Affect Conception
Many women with ovarian cysts can conceive naturally. Treatment for fertility concerns depends on whether the cyst itself, an underlying condition, or another reproductive factor is contributing to difficulty conceiving.
A fertility specialist may evaluate ovulation, ovarian reserve, fallopian tube health, and sperm-related factors before recommending treatment. Depending on the findings, options may include addressing an underlying condition, expectant management, or assisted reproductive techniques such as in vitro fertilisation (IVF).
IVF is not automatically necessary for women with ovarian cysts. The most appropriate approach is based on a complete fertility assessment.
5. Lifestyle and Supportive Care
Maintaining a balanced diet, engaging in regular physical activity, and tracking menstrual cycles can support general health. However, lifestyle changes alone are not proven to prevent or treat every type of ovarian cyst.
Follow your clinician’s advice regarding symptom management and any recommended follow-up examinations.
When Should You See a Doctor for an Ovarian Cyst?
Consider consulting a gynaecologist if you experience persistent pelvic pain, ongoing bloating, unusual menstrual changes, or symptoms that interfere with everyday activities.
Sudden or Severe Pelvic Pain
Sudden, intense pelvic pain, especially with nausea, vomiting, dizziness, or fainting, requires emergency medical assessment. Do not wait for a routine appointment if these symptoms occur.
Persistent Bloating or Abdominal Swelling
Ongoing abdominal swelling, pressure, or a persistent feeling of fullness should be evaluated, particularly if the symptoms are new or worsening.
Irregular or Missed Periods
Irregular or missed periods may be associated with PCOS, changes in ovulation, pregnancy, thyroid conditions, or other causes. A medical assessment can help identify the reason rather than assuming an ovarian cyst is responsible.
Difficulty Conceiving
If you have been trying to conceive without success, or you have known endometriosis, irregular ovulation, or a history of ovarian surgery, consider seeking a fertility assessment. The appropriate timing depends partly on age and medical history.
Other Persistent Symptoms
Pain during intercourse, frequent urination, ongoing lower abdominal discomfort, or unexplained changes in symptoms may warrant evaluation.
Routine screening ultrasound is not recommended for every asymptomatic person at average risk of ovarian cancer. Follow-up should be based on symptoms, previous findings, and individual risk factors.
Ovarian Cysts and Fertility: What Should You Know?
An ovarian cyst does not automatically mean infertility. Many functional cysts have little or no long-term effect on fertility and resolve naturally.
The impact on conception depends on the type of cyst and any associated condition. For example:
- Functional cysts often resolve without affecting long-term fertility.
- Endometriomas may be associated with endometriosis-related fertility challenges.
- PCOS can affect ovulation and menstrual regularity.
- Surgery involving the ovaries may sometimes reduce ovarian reserve, depending on the procedure and the condition being treated.
If you are planning a pregnancy, discuss your goals with your gynaecologist before deciding on treatment. In some cases, monitoring may be preferable to surgery; in others, intervention may be necessary for safety or symptom relief.
