OHSS warning signs

Symptoms after egg collection that need urgent medical review.

Complications

Contact your clinic urgently, or attend an emergency department if the clinic is closed, if you have rapidly increasing abdominal swelling, severe pain, persistent vomiting, breathlessness, reduced urine output, or sudden weight gain of a kilogram or more per day. Mild bloating and discomfort after egg collection are common; these symptoms are not.

Also known as: severe OHSS symptoms, when to call the clinic
