Ovarian hyperstimulation syndrome - OHSS

This syndrome develops as a result of exogenous therapy with gonadotrophins and occurs in 1-5% of women treated in this way. The greatest risk factor for the development of ovarian hyperstimulation syndrome is the PCO syndrome.

Symptoms of OHSS are:

  • Pain in the lower part of the abdomen
  • Nausea / vomiting
  • Increase in body weight

The expression of the symptoms varies, can be easily or severely expressed.

In severe forms of OHSS, there is:

  • Strong abdominal pain
  • Distended abdomen
  • Ascites (free fluid in the abdomen)
  • Dyspnoea (difficulty breathing)
  • Oliguria (reduced urine secretion)
  • Thromboembolism

The diagnosis is based on the above symptoms and the ultrasound findings of the enlarged ovary, with a multitude of follicular cysts, a free fluid in the abdomen.

Treatment depending on the severity of the symptoms may be outpatient or hospital.
