Ovarian Torsion: Sudden Pelvic Pain and Emergency Care
Sudden severe one-sided pelvic pain with nausea or vomiting can be ovarian torsion, a time-sensitive emergency. Get urgent hospital assessment now.
In this guide
What are the warning signs of ovarian torsion?
Ovarian torsion happens when an ovary and sometimes the fallopian tube twist and reduce the blood supply. Sudden severe lower-abdominal or pelvic pain—often on one side—with nausea or vomiting can be a warning sign. Pain may come and go or remain severe. If this is happening now, go to an emergency department immediately; do not wait for a routine appointment or try to diagnose it at home.
Sudden severe pelvic pain needs emergency assessment
Pain may be sharp, one-sided or intermittent and can spread to the back, groin or side. Nausea, vomiting or feeling very unwell may occur. These symptoms can also have other urgent causes, including ectopic pregnancy, appendicitis or a ruptured cyst, so emergency clinicians need to assess you promptly.
Torsion can happen without a known cyst
An ovarian cyst or mass, pregnancy or fertility treatment may increase risk, but torsion can happen without a person knowing about a cyst. It can occur at different ages. A history of cysts is useful information for clinicians, but no known risk factor is a reason to dismiss sudden severe pain.
Call for help if pain prevents safe travel
Ask someone to take you to the nearest emergency department or call India’s 112 emergency number if you need immediate assistance. Tell staff when pain began, whether it comes and goes, if you vomited, whether pregnancy is possible and whether you have had ovarian cysts or fertility treatment. Do not delay care to complete a symptom diary.

How do clinicians check for ovarian torsion?
Emergency assessment may include examination, pregnancy testing, blood or urine tests and ultrasound. No single symptom or scan result should be used by a patient to rule torsion out. A specialist weighs the whole picture and decides whether urgent surgery is needed.
Ultrasound can help, but it may not settle the question
An ultrasound may show an enlarged ovary or other findings that support torsion. ACOG’s guidance for adolescents says normal Doppler blood flow alone does not rule out torsion. That guidance is adolescent-focused and must be interpreted by the treating team; a scan should not delay emergency specialist assessment when suspicion remains.
Tell the team if pregnancy is possible
Pregnancy testing helps clinicians consider ectopic pregnancy and choose suitable investigations and treatment. Share the date of your last period, any pregnancy test result, medicines and allergies. You can ask what each examination or test involves, but urgent evaluation should not be delayed when severe pain is present.
Ask who will explain the next step
A gynaecology or surgical team may assess you urgently. Ask what findings raise concern, whether observation or an operation is being considered and how quickly a decision is needed. If you are able, ask someone you trust to take notes while the team speaks directly to you.
What treatment may be needed for ovarian torsion?
Suspected torsion is treated as time-sensitive because delay can threaten blood supply and ovarian function. A gynaecologist may recommend urgent surgery to confirm the diagnosis and untwist the ovary. The operation and fertility implications depend on what the surgeon finds and the person’s health.
Urgent surgery may protect the ovary
When torsion is suspected, a clinician may recommend laparoscopy, a keyhole operation, to look at the ovary and untwist it. ACOG guidance emphasizes timely intervention in adolescents to preserve ovarian function and future fertility. The surgeon can explain what is planned and what might change during the operation.
Ask whether the ovary can be preserved
Where the situation allows, ask the surgeon whether the goal is to untwist and preserve the ovary, whether a cyst may also need treatment and what would make removal necessary. If you are able to discuss this before surgery, tell the team about future pregnancy goals. Emergency care may limit how much planning time is available.
Aftercare should include a clear review plan
Before discharge, ask about pain control, wound care, activity, pathology or scan results if relevant, and who to call if pain, fever, vomiting or bleeding returns. If a cyst or underlying condition contributed, ask whether follow-up is needed to reduce the chance of another episode.
Ovarian torsion: frequently asked questions
Can ovarian torsion pain come and go?
Yes. Pain can be intermittent or constant. Sudden severe pelvic pain with nausea or vomiting still needs immediate emergency assessment even if it eases temporarily.
Does normal blood flow on Doppler rule out torsion?
No. ACOG guidance for adolescents says Doppler flow alone should not guide decisions or rule out torsion. The specialist uses the symptoms, examination and full imaging picture.
Can ovarian torsion happen without an ovarian cyst?
Yes. A cyst or mass can raise risk, but torsion can occur without a known cyst. A lack of prior diagnosis does not make sudden severe pain safe to ignore.
Is ovarian torsion an emergency?
Yes. It can interrupt blood supply to the ovary and needs urgent hospital assessment. Go to an emergency department now if symptoms suggest torsion.
Words you can use
Tell emergency staff the key details
At emergency triage or while a supporter calls for help
“I have sudden [right / left / central] lower-abdominal or pelvic pain that began at [time]. It is [constant / coming and going], and I have [nausea, vomiting or other symptoms]. Pregnancy is [possible / not possible / uncertain]. I have [a known cyst / fertility treatment / no known cyst]. Could a gynaecology team assess me urgently for torsion and other emergencies?”
