What do I need to know about Ovarian Hyperstimulation Syndrome?
Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal reaction to gonadotrophin fertility drugs. It causes your ovaries to grow large and painful and can lead to fluid leaking into your abdomen. Around a third of women will have mild OHSS, which can normally be effectively treated at home with pain relief.
Fewer women will develop moderate or severe OHSS but, in very rare cases, severe OHSS can be life-threatening so it’s very important you report any symptoms to your clinic.
Symptoms of OHSS include:
- swollen stomach and stomach pains (can be severe)
- nausea and vomiting
- shortness of breath
- reduced urine output.
Patients who develop strong OHSS symptoms generally do so the week after egg collection.
If you experience any of these symptoms you should contact your clinic immediately. Never feel you are wasting the clinic’s time.
