Knowledge | Ovarian Hyperstimulation Syndrome: A Hidden Risk of Fertility Treatment
Ovarian hyperstimulation syndrome (OHSS) occurs when the ovaries overreact to hormonal stimulation. It usually affects women undergoing in vitro fertilization (IVF) who receive follicle-stimulating injections. OHSS causes swollen, painful ovaries and possible fluid leakage. It is not a chronic condition, but without prompt treatment it can cause serious complications.
1. Causes of OHSS
OHSS is mainly triggered by human chorionic gonadotropin (HCG). HCG is produced by placental cells that form the embryo and can be detected within one week of fertilization. Excessive levels may cause the ovaries to swell and leak fluid. Naturally elevated HCG rarely causes OHSS; it is more common during fertility treatment, particularly after HCG injections.
2. Symptoms of OHSS
Symptoms range from mild discomfort to severe illness. Mild symptoms include weight gain, abdominal bloating or pain, nausea, vomiting, diarrhea, and ovarian tenderness. Severe symptoms may include:
Rapid or excessive weight gain
Difficulty breathing
Reduced urination
Blood clots
Contact a doctor immediately if these symptoms occur. Early intervention can prevent serious complications.
3. Diagnosis and Treatment
If symptoms appear during fertility treatment, a doctor may perform a physical examination, ultrasound, X-ray, and blood tests to assess severity and plan treatment.
Mild OHSS can usually be managed with more fluids, moderate rest, and over-the-counter pain medication. Most mild cases resolve within two weeks. Severe OHSS may require hospitalization, intravenous fluids, medication, and drainage of abdominal fluid.
4. Prevention
Doctors tailor fertility treatment to reduce OHSS risk. Measures include adjusting the HCG dose, using medication to reduce ovarian activity, and stopping HCG injections when necessary. During IVF, a doctor may recommend retrieving and freezing mature eggs to give the ovaries time to recover.
Risks and Complications
Complications can be severe or fatal. Fluid leakage may increase abdominal pressure and cause dehydration, leading to life-threatening blood clots in the legs or lungs. Early recognition and intervention are essential.
When to Contact a Doctor
During fertility treatment, contact a doctor immediately for difficulty breathing, severe abdominal pain, inability to eat or drink, daily weight gain over 2 pounds, dizziness, or reduced urination.
