What are ovarian cysts?

A cyst is a fluid-filled sac on or in an ovary. They can vary in size from small (less than 2 cm) to larger cysts, which can cause discomfort. Most cysts are functional, meaning that they occur in connection with the menstrual cycle and often disappear on their own within a few months. Other cysts can be more complex and require follow-up to rule out diseases such as endometriosis or, rarely, cancer.

Symptoms

Many cysts cause no symptoms and are only discovered during a routine examination. When symptoms do occur, they may include:

It is important to seek medical attention if the pain is severe or sudden, as this may be a sign that a cyst has ruptured or is causing twisting of the ovary.

Consultation with gynecologist

If you have symptoms or have been diagnosed with a cyst, a consultation with our gynecologist can provide clarity and reassurance. During the consultation, we will review:

  • Your medical history and menstrual pattern
  • Results from ultrasound or blood tests
  • Possible causes and treatment options

The gynecologist will assess whether the cyst can be monitored or whether medical or surgical treatment is required. You will also receive guidance on what to look out for in the future.

Treatment of cysts

Most functional cysts require no treatment and disappear spontaneously. Other options include:

Observation

Repeated examinations to monitor the size of the cyst

Medical treatment

Some hormonal preparations can reduce the formation of new cysts.

Surgery

In rare cases, the cyst is surgically removed, especially if it is large, persistent, or causes symptoms.

Frequently asked questions about ovarian cysts

What symptoms can a cyst cause?

Many cysts cause no symptoms. When symptoms do occur, they may include abdominal pain, irregular menstruation, pressure in the abdomen, bloating, or pain during intercourse. Severe, sudden pain should always be evaluated by a doctor.

How are cysts detected?

Cysts are often detected during a routine gynecological examination or ultrasound. Some are only detected when they cause symptoms.

How are cysts treated?

Smaller, functional cysts often require no treatment and disappear on their own. Larger or persistent cysts can be monitored with ultrasound, treated with medication, or, in rare cases, removed surgically. The choice of treatment depends on the type of cyst, its size, symptoms, and your future plans.

Are cysts dangerous?

Most cysts are benign and harmless. In rare cases, a cyst can be a sign of disease or cancer. It is therefore important to have it assessed by a gynecologist, especially if the cyst causes symptoms or changes in size.

Can cysts affect fertility?

Most cysts do not affect fertility. In some cases, large or complex cysts may be significant, and this is assessed individually by the gynecologist.

When should I seek help?

Contact a gynecologist if you experience severe pain, sudden changes in your stomach or abdomen, irregular menstruation, or other worrying symptoms.
