Symptoms and Diagnosis

[1] Initially women with OHSS will present with abdominal bloating, as a result of fluid in the peritoneal cavity and an increase in ovary size. Whilst symptoms can occur as soon as 24 hours post hCG administration, they are usually seen in women 7-10 days post administration. When women present with severe OHSS they are often dehydrated, due to increased vascular permeability, and have hemoconcentration. The above results in a decrease in intravascular volume, leading to oligouria.

A key diagnostic tool for clinicians regarding women who are taking gonadotropins is to identify if they are at an increased risk of developing OHSS. Some risk factors include woman aged less than 30, women who have polycystic ovaries, woman with a previous history of OHSS and women who have greater than 20 oocytes retrieved. After a history of the patient is taken, the next step is to perform a physical exam on the woman. Women who present with abdominal bloating will produce a shifting dullness upon abdominal percussion. If the clinician further suspects a women of having OHSS, a ultrasound can be done.The intraperitoneal fluid is best images via vaginal ultrasound due to the enlarged ovaries making it difficult to image the pelvis using transabdominal ultrasound.

Once a women has been diagnosed as having OHSS, they are classified based on a criteria from mild, moderate and severe. [1]
