Ovarian cysts are fluid-filled sacs or pockets within or on the surface of an ovary. They are a common gynecological condition and can vary greatly in size. Most ovarian cysts are benign (non-cancerous) and often resolve on their own without treatment. However, some can cause symptoms and may require medical intervention.

Symptoms of Ovarian Cysts
Many ovarian cysts are asymptomatic and are discovered incidentally during routine pelvic examinations or imaging studies performed for other reasons. When symptoms do occur, they may include:
| Symptom | Description |
|---|---|
| Pelvic Pain | A dull or sharp ache in the lower abdomen on the side of the cyst |
| Fullness or Heaviness | A sensation of fullness or heaviness in the abdomen |
| Bloating | Abdominal bloating or swelling |
| Pain During Intercourse | Pain during sexual intercourse, particularly with deep penetration |
| Menstrual Irregularities | Changes in menstrual cycles, including irregular periods, unusually painful periods (dysmenorrhea), or abnormal bleeding |
| Urinary Symptoms | Increased frequency or urgency to urinate, or difficulty emptying the bladder completely |
| Bowel Movement Issues | Difficulty with bowel movements or pressure on the bowels |
| Nausea and Vomiting | These symptoms can occur if the cyst causes twisting of the ovary (ovarian torsion) |
| Breast Tenderness | Similar to the tenderness experienced during pregnancy or menstrual cycles |
| Hormonal Imbalances | Changes in hormone levels that can lead to symptoms such as acne or unusual hair growth |
Severe symptoms that require immediate medical attention include:
| Symptom | Description |
|---|---|
| Sudden, Severe Pelvic Pain | This could indicate a ruptured cyst or ovarian torsion |
| Pain with Fever or Vomiting | These symptoms may suggest an infection or other complication |
| Cold, Clammy Skin | This can be a sign of shock, which requires emergency care |
| Rapid Breathing | This may also indicate a severe reaction or complication |
| Lightheadedness or Weakness | These symptoms can occur with significant internal bleeding |
Causes of Ovarian Cysts
Ovarian cysts can develop for various reasons, and the exact cause often depends on the type of cyst. The main types and their causes include:
| Type | Description | Cause |
|---|---|---|
| Functional Cysts | The most common type of ovarian cyst | These cysts form as a result of the menstrual cycle. They include follicular cysts, which occur when a follicle does not rupture to release an egg, and corpus luteum cysts, which form when the corpus luteum fills with blood |
| Dermoid Cysts | Also known as teratomas | These cysts contain tissue such as hair, skin, or teeth because they form from embryonic cells. They are usually benign |
| Cystadenomas | Develop on the surface of an ovary | These cysts are filled with a watery or mucous material and can grow quite large |
| Endometriomas | Associated with endometriosis | These cysts form when endometrial tissue (the tissue lining the uterus) grows outside the uterus and attaches to the ovary |
| Polycystic Ovary Syndrome (PCOS) | A condition characterized by multiple small cysts on the ovaries | PCOS is related to hormonal imbalances that prevent the follicles from releasing eggs, leading to the formation of many small cysts |
| Cancerous Cysts | Rare but serious | These cysts are malignant and can be associated with ovarian cancer |
Risk Factors
Several factors can increase the likelihood of developing ovarian cysts:
| Factor | Description |
|---|---|
| Hormonal Problems | Including those related to fertility drugs used to induce ovulation |
| Pregnancy | Cysts can sometimes develop during early pregnancy to support the pregnancy until the placenta forms |
| Endometriosis | A condition where uterine endometrial cells grow outside the uterus |
| Severe Pelvic Infections | Infections that spread to the ovaries and fallopian tubes |
| Previous Ovarian Cysts | Having had ovarian cysts in the past increases the risk of developing them again |
Diagnosis
Diagnosing ovarian cysts typically involves a combination of the following methods:
| Method | Description |
|---|---|
| Pelvic Examination | During a pelvic exam, a healthcare provider may feel swelling on an ovary and suspect a cyst |
| Ultrasound | An ultrasound can confirm the presence of a cyst, determine its location, and identify whether it is solid, filled with fluid, or mixed |
| Laparoscopy | A minimally invasive surgical procedure where a small camera is inserted into the abdomen to view the ovaries and remove the cyst if necessary |
| Blood Tests | Tests such as the CA 125 blood test can help detect proteins that may indicate the presence of ovarian cancer, although this test is not definitive for cysts |
| Pregnancy Test | A positive pregnancy test may suggest the presence of a corpus luteum cyst |
| Hormone Level Tests | These can help diagnose conditions such as PCOS |
Treatment
Treatment for ovarian cysts depends on the size and type of the cyst, the woman’s age, and her symptoms. Options include:
| Treatment | Description |
|---|---|
| Watchful Waiting | Many cysts, especially functional cysts, go away on their own within a few months. Regular ultrasound scans may be recommended to monitor the cyst |
| Medications | Birth control pills can help prevent the formation of new cysts by preventing ovulation. Pain relievers may be recommended for discomfort |
| Surgery | Large cysts, cysts that are causing symptoms, or cysts that appear suspicious for cancer may need to be surgically removed. Procedures can range from laparoscopic surgery to remove the cyst to more extensive surgery such as an oophorectomy (removal of the ovary) or hysterectomy (removal of the uterus and ovaries) |
Complications
While most ovarian cysts are harmless, some can lead to complications, including:
| Complication | Description |
|---|---|
| Rupture | A ruptured cyst can cause severe pain and internal bleeding |
| Ovarian Torsion | Large cysts can cause the ovary to twist, cutting off its blood supply |
| Infertility | Certain types of cysts, such as those associated with endometriosis or PCOS, can affect fertility |
| Cancer | Although rare, some cysts may be cancerous |
Prevention
While it is not always possible to prevent ovarian cysts, regular gynecological exams can help detect them early. Maintaining a healthy lifestyle and managing conditions such as PCOS can also reduce the risk of developing cysts.
Conclusion
Ovarian cysts are a common condition that affects many women at some point in their lives. While most cysts are harmless and resolve on their own, some can cause symptoms and complications that require medical attention. Understanding the symptoms and causes of ovarian cysts can help women seek appropriate care and manage their health effectively. Regular medical check-ups and open communication with healthcare providers are essential for early detection and treatment.
