Ovarian torsion is a medical condition that occurs when an ovary twists around the ligaments that hold it in place. This twisting can cut off the blood supply to the ovary, leading to severe pain and potential damage. It often affects women of reproductive age and can happen suddenly. Symptoms of ovarian torsion include sharp abdominal or pelvic pain, nausea, and vomiting. If not treated quickly, it can result in the loss of the affected ovary. Diagnosis typically involves imaging tests like an ultrasound, and treatment usually requires surgery to untwist the ovary and restore blood flow.
