OHSS is due to chemicals produced by the follicles which then cause leakage of fluid into the abdominal cavity and reduces the circulating fluid in your blood vessels. Untreated, it may result in:

  • Thickening of the blood which interferes with its circulation and may start to form clots and there is also a risk that these may travel elsewhere (embolism), for example to the lungs or the brain.
  • The reduction in circulating fluid volume can cause impaired blood flow to kidneys and reduce urine output.
  • Sudden breathlessness has also been reported as a result of OHSS.

It is therefore a very serious condition which we try to ensure is recognised in very early stages, is monitored and treated accordingly.

What are the symptoms of OHSS?

The warning symptoms are thirst, nausea (feeling sick), abdominal pain, abdominal bloatedness, shortness of breath, vomiting, diarrhoea and general malaise.
