Symptoms of Ovarian Hyperstimulation Syndrome

The symptoms of OHSS vary depending upon how severe the condition is. Symptoms typically manifest four or five days after egg collection, and are often associated with pregnancy. Possible symptoms include:


  • nausea and vomiting
  • diarrhea
  • abdominal bloating and distension
  • abdominal pain
  • sudden weight gain (due to fluid accumulation in the stomach)
  • the appearance of cysts on the ovaries
  • difficulty breathing

Additionally, depending on the severity of your OHSS, you may experience reduced frequency in your urination as well as dark urine.


Complications of Ovarian Hyperstimulation Syndrome

If left untreated, OHSS can result in serious health complications. Severe cases of OHSS are rare, but they have been known to lead to permanent injury and even death. Possible complications include:


  • twisting of the swollen ovaries (which may require their removal and loss of fertility)
  • collection of fluid in the stomach and lungs (which interferes with bodily processes, including breathing)
  • loss of kidney and liver function
  • blood clots (which may lead to stroke)


Treating Ovarian Hyperstimulation Syndrome


Typically, OHSS symptoms will disappear on their own. However, if you are experiencing any of the symptoms of OHSS it is important that you inform your reproductive endocrinologist right away. She will perform an examination as soon as possible and recommend further treatment.

Treatment may include:

  • monitoring symptoms such as weight gain and frequency of urination
  • reduction of activities, including sexual intercourse
  • removal of excess fluids in the abdomen
  • stopping hCG and other forms of infertility drugs
  • freezing of eggs or embryos for implantation later on


Steps to Prevent Ovarian Hyperstimulation Syndrome


If you decide to undergo ovulation induction, be sure that your reproductive endocrinologist is taking steps to monitor your progress. Careful monitoring can help to reduce your chances of developing OHSS in the first place.

The best prevention techniques include:

  • frequent monitoring of your ovaries and follicular development using ultrasound
  • frequent testing of your blood estrogen levels
