Ovarian cysts are fluid-filled sacs on the ovary. Most are functional cysts linked to the menstrual cycle and disappear on their own within a few cycles. They are diagnosed with a pelvic ultrasound; your doctor decides whether to monitor, treat symptoms or refer for surgery based on the cyst's size, appearance and your symptoms.

Types of ovarian cysts
- Functional cysts (follicular, corpus luteum) — the most common, usually harmless.
- Endometriomas — related to endometriosis.
- Dermoid cysts and cystadenomas — may need removal depending on size.
- Multiple small follicles can be part of PCOS.
Symptoms
Many cysts cause no symptoms and are found on a routine ultrasound. Others cause pelvic pressure, bloating, one-sided pain or pain during sex.
Seek urgent care for sudden severe pelvic pain, especially with fever, vomiting or fainting — this can signal rupture or twisting of the ovary.
Treatment options
- Watchful waiting with a follow-up ultrasound after one to three cycles.
- Medication for pain or hormonal management where appropriate.
- Referral for surgery if a cyst is large, persistent, suspicious or causing complications.
