Ovarian hyperstimulation syndrome (OHSS)

Based on severity, the symptoms of OHSS are classified as mild, moderate and severe. Mild symptoms include bloating, nausea and weight gain from fluid collection. This is experienced by 1 out of 3 women on controlled ovarian stimulation to enhance in vitro fertilization. With moderate OHSS these symptoms are more severe. In severe OHSS, women experience severe vomiting, shortness of breath and blood clots in the legs.
