An ovarian cyst is a fluid-filled sac that can form in the ovaries, which are small organs responsible for producing eggs and female hormones. The ovaries play a crucial role in regulating the body’s appearance, menstrual cycle, and pregnancy.There are several types of ovarian cysts, with functional cysts being the most common. Functional cysts develop during ovulation. Each month, eggs grow in tiny sacs called follicles. After releasing the egg, the follicle usually dissolves and forms a structure called the corpus luteum, which produces hormones. If the follicle does not dissolve, it can turn into a functional cyst. These cysts generally disappear on their own within a few months and are rarely cancerous, though they may cause mild symptoms.Other types of ovarian cysts can form due to disease or if the egg is not released. These cysts may be larger and more painful. While some ovarian cysts cause no symptoms, others may present the following symptoms:

• Pressure, swelling or pain in the abdomen
• Pelvic pain
• Pain during sex
• Weight gain
• Abnormal bleeding
• Nausea
• Vomiting

Ovarian cysts are often diagnosed during a routine pelvic exam. An ultrasound or blood test may also be used to determine the size and type of the cyst. Many cysts resolve on their own, so initial treatment may involve monitoring to see if the cyst changes in size. Surgery may be necessary for cysts that do not change or cause pain. If you suspect you have a cyst, schedule a pelvic exam with your doctor.
