Ovarian cysts are one of the most frequently diagnosed gynaecological conditions, often discovered incidentally during pelvic examinations or ultrasound scans. While many cysts are harmless and resolve naturally, some can cause discomfort, affect fertility, or signal an underlying condition requiring medical attention. Understanding the different types of ovarian cysts, how they form, and what they mean for your reproductive health can empower women to take proactive steps towards care and prevention.

For a detailed overview of symptoms and treatment options, you can explore this main article on Ovarian Cysts: Symptoms, Causes, and When to Worry, which offers comprehensive insight into diagnosis, management, and when to seek medical help.

What are Ovarian Cysts and Why Do They Form?

Ovarian cysts are fluid-filled sacs that develop either on the surface or inside one or both ovaries. They are especially common in women of reproductive age and can occur for several reasons — most often due to hormonal fluctuations associated with ovulation.

During a normal menstrual cycle, the ovaries release an egg every month. If the follicle fails to release the egg or does not dissolve after ovulation, it can continue growing, forming what is known as a functional cyst. Most functional cysts disappear on their own within a few weeks or months, but persistent or complex cysts may require further evaluation.

Other causes include endometriosis (which can lead to endometriomas), infections, or polycystic ovary syndrome (PCOS), where multiple small cysts form due to disrupted ovulation cycles.

Common Types of Ovarian Cysts

There are several types of ovarian cysts, each with unique characteristics, causes, and implications:

1. Functional Cysts

These are the most common and include:

• Follicular cysts: Develop when the follicle does not release an egg.
• Corpus luteum cysts: Occur after ovulation when the follicle closes but fluid accumulates inside.

Functional cysts are usually benign and resolve naturally without treatment.

2. Dermoid Cysts

Also known as mature cystic teratomas, these cysts can contain tissue such as hair, skin, or even teeth because they originate from cells that can produce different body tissues. Although usually non-cancerous, dermoid cysts can grow large and cause pain or ovarian torsion if not treated.

3. Endometriomas

These are associated with endometriosis, a condition in which tissue similar to the lining of the uterus grows outside it. When this tissue attaches to the ovaries, it forms cysts filled with dark, old blood — often called “chocolate cysts.” Endometriomas may cause chronic pelvic pain and fertility issues.

4. Cystadenomas

These form on the surface of the ovary and can be filled with watery or mucous material. While benign, cystadenomas can become large and lead to pressure symptoms in the abdomen or pelvis.

5. Polycystic Ovaries

In polycystic ovary syndrome (PCOS), multiple small cysts form due to irregular ovulation. PCOS is not only a gynaecological condition but also a hormonal disorder that affects metabolism, menstrual regularity, and fertility.

How Ovarian Cysts Affect Reproductive Health

While many cysts don’t cause symptoms, certain types can impact fertility, hormonal balance, or general wellbeing.

• Pain and discomfort: Large cysts can cause pelvic pain, bloating, or pressure on nearby organs.
• Fertility concerns: Endometriomas and cysts linked to PCOS can interfere with ovulation, making it harder to conceive.
• Menstrual irregularities: Some cysts can lead to heavy or irregular periods.
• Emotional distress: Chronic pelvic pain and anxiety about diagnosis can affect emotional health and quality of life.

Understanding these potential effects underscores why monitoring and early diagnosis are essential.

When an Ovarian Cyst Becomes a Medical Emergency

Although most cysts are benign, complications can occur in rare cases:

• Ovarian torsion: A large cyst can cause the ovary to twist, cutting off its blood supply and leading to severe, sudden pain and nausea.
• Cyst rupture: This can cause internal bleeding and sharp pain in the lower abdomen.
• Malignant cysts: While uncommon, some cysts may develop into ovarian cancer, particularly in postmenopausal women.

If you experience sudden severe abdominal pain, fever, vomiting, or dizziness, urgent medical evaluation is necessary.

Diagnosis: How Cysts Are Detected

The diagnostic process often includes:

• Pelvic examination: To detect swelling or tenderness.
• Ultrasound scan: The gold standard for determining size, type, and characteristics of cysts.
• Blood tests: Including CA-125 and hormonal assessments to rule out malignancy or hormonal imbalance.
• MRI or CT scans: Used in complex or uncertain cases for better visualisation.

Early diagnosis allows for more targeted management and helps prevent complications.

Treatment and Management

The right treatment depends on the cyst’s size, type, and symptoms, as well as the woman’s age and fertility plans.

• Observation: Many small, simple cysts disappear naturally within a few cycles.
• Hormonal therapy: Contraceptive pills may prevent the formation of new cysts but won’t shrink existing ones.
• Surgical removal: Laparoscopic surgery (keyhole) or laparotomy may be needed for large or suspicious cysts.
• Fertility preservation: For women planning pregnancy, careful surgical techniques can protect ovarian tissue and reproductive function.

Pain relief measures such as anti-inflammatory medication, heat therapy, and gentle exercise can help alleviate discomfort during recovery.

Lifestyle and Preventive Care

Though not all cysts can be prevented, maintaining hormonal balance and general wellbeing can reduce risks:

• Balanced diet: Eating foods rich in fibre and low in refined sugars supports hormonal stability.
• Regular exercise: Helps maintain a healthy weight and regulates menstrual cycles.
• Stress management: Chronic stress can influence hormonal health; mindfulness or yoga can help.
• Routine check-ups: Regular gynaecological visits ensure any cysts are detected early and monitored appropriately.

Emotional Support and Mental Well-being

Learning you have an ovarian cyst can trigger anxiety, particularly if you’re concerned about fertility or cancer. Women often feel uncertain until they receive detailed imaging and medical reassurance. Open communication with a gynaecologist helps to clarify risks and treatment options, reducing emotional strain.

Many clinics now offer personalised consultations where patients can discuss their symptoms, review scan results, and explore treatment pathways. For personalised advice, you can book a private gynaecology consultation to receive expert evaluation and tailored recommendations in a comfortable and confidential environment.

Role of Ultrasound in Early Detection

Ultrasound scanning plays a vital role in identifying ovarian cysts before they cause complications. Transvaginal ultrasound provides a detailed view of the ovaries, allowing doctors to distinguish between simple and complex cysts. Early detection means that benign cysts can be safely monitored, and problematic ones can be addressed before they escalate.

Routine pelvic imaging is particularly beneficial for women with irregular periods, a history of endometriosis, or fertility challenges.

When to Follow Up

Even after a cyst resolves, regular monitoring is advised to ensure no recurrence or new formation. Your specialist may recommend repeat ultrasounds every few months. Post-treatment follow-ups are equally important for women who have undergone surgery, as hormonal regulation may take time to normalise.

Staying alert to bodily changes — such as pelvic discomfort, bloating, or altered menstrual flow — ensures prompt intervention if new cysts develop.

Final Thoughts

Ovarian cysts are extremely common, but understanding their types, symptoms, and risks helps women make informed health decisions. Regular scans, timely diagnosis, and a healthy lifestyle can prevent most complications. Emotional wellbeing is equally vital, as reassurance and education alleviate much of the anxiety surrounding these conditions.
