Modern antagonist protocols and freeze-all strategies have made severe OHSS rare, but recognising it early still matters: untreated severe cases affect breathing, clotting and kidney function.
When to seek care
During stimulation, rapid abdominal swelling, severe pain, vomiting or breathlessness deserve same-day contact with your clinic — do not wait for the next scheduled scan.
