Osmosis video - Ovarian cyst

An ovarian cyst is any fluid-filled sac that develops in the ovary. Common ovarian cyst types are corpus luteum cysts, theca-lutein cysts, dermoid cysts, endometrioid cysts, etc. Most ovarian cysts do not cause any symptoms unless they either break open or cause the ovary to twist and become ischemic (ovarian torsion). This can result in lower abdominal and back pain, vomiting and feeling faint, bloating, and loss of the affected ovary.
