What is an Ovarian Cyst?

An ovarian cyst is a fluid-filled or semi-solid sac that develops on the ovaries. Most are harmless and may disappear without causing symptoms. However, in some cases, cysts can grow and lead to health problems.

Types of Ovarian Cysts

Ovarian cysts are classified into two main groups: functional and pathological.

1. Functional Cysts (Hormone-Related Cysts)

• Follicular Cysts:
  • Develop when the follicle that releases the egg during ovulation continues to grow.
  • Often asymptomatic and usually disappear on their own.
• Corpus Luteum Cysts:
  • Form when the corpus luteum tissue enlarges after ovulation.
  • May cause delayed menstruation and pelvic pain.

2. Pathological Cysts (Due to Abnormal Cell Growth)

• Dermoid Cysts (Mature Cystic Teratoma): May contain hair, fat, or teeth. Common in younger women and may require surgery.
• Endometrioma (Chocolate Cyst): Caused by endometriosis, contains dark blood. Associated with severe menstrual pain and infertility.
• Serous and Mucinous Cystadenomas: Benign but may grow large. Larger cysts are surgically removed.
• Polycystic Ovary Syndrome (PCOS): Multiple small cysts develop due to hormonal imbalance.
• Malignant (Cancerous) Cysts: Rare, but require attention especially after menopause.

Causes of Ovarian Cysts

• Hormonal Imbalances: Excess estrogen production or ovulation disorders may play a role.
• Polycystic Ovary Syndrome: Causes small cysts due to irregular ovulation.
• Endometriosis: Endometrial tissue outside the uterus may cause chocolate cysts.
• Pregnancy: Corpus luteum cysts may develop during pregnancy.
• Pelvic Infections: Can damage ovaries and fallopian tubes, leading to cyst formation.
• Genetic Factors: Family history increases the risk of cysts.

Symptoms of Ovarian Cysts

• Lower abdominal pain or pressure
• Menstrual irregularities
• Pain during sexual intercourse
• Bloating or abdominal fullness
• Frequent urination or digestive complaints
• Nausea or vomiting (if the cyst ruptures)
• Weight gain, excessive hair growth (associated with PCOS)

Emergency Symptoms

• ⚠ Severe abdominal or pelvic pain
• ⚠ Sudden, sharp pain
• ⚠ Dizziness, fainting, rapid heartbeat

If these symptoms occur, immediate medical attention is required.

How Are Ovarian Cysts Diagnosed?

• Gynecological Examination: Cysts may be detected during a pelvic exam.
• Ultrasound: Used to evaluate the size and structure of the cyst.
• Blood Tests (CA-125): Tumor marker test if cancer is suspected.
• MRI or CT Scan: Provides detailed imaging for large or suspicious cysts.

Treatment Options for Ovarian Cysts

1. Observation and Monitoring

• Small, functional cysts often disappear on their own.
• Can be monitored with ultrasound every 1–3 months.

2. Medication

• Birth control pills may help prevent new cyst formation.

3. Surgical Intervention

• Laparoscopy: Minimally invasive surgery for small cysts.
• Laparotomy: Open surgery for large or suspicious cysts.
• Oophorectomy: Removal of the ovary if necessary.

4. Special Approach for PCOS

• Diet, exercise, and hormonal medications help manage symptoms.
• Weight loss may reduce insulin resistance and improve outcomes.

Conclusion

Most ovarian cysts are harmless and resolve spontaneously. However, some can grow and cause serious health problems. If you experience pelvic pain, menstrual irregularities, or bloating, consult a gynecologist. Early diagnosis is vital to prevent severe complications.
