Ovarian cyst

An ovarian cyst is any fluid-filled sac within the ovary. Often they cause no symptoms. Occasionally they may produce bloating, lower abdominal pain, or lower back pain. If the cyst either breaks open or causes twisting of the ovary severe pain may occur. This may result in vomiting or feeling faint. The majority of cysts are, however, harmless. Cysts can be caused by hormonal imbalances, carcinomas or normal physiologic functions of the ovary. Some common cyst types are corpus luteum cysts, theca-lutein cysts, dermoid cysts, endometroid cysts etc.
