Ovarian hyperstimulation syndrome
Type of disease: Rare conditions
Ovarian hyperstimulation syndrome (OHSS) is a disorder that usually is caused by taking hormonalmedications to stimulate the development of eggs in the ovaries. In OHSS, the ovaries become swollen and painful. Symptoms usually present within 10 days after taking the medications, though the severity of symptoms varies and may worsen or improve over time. Moderate symptoms include nausea, vomiting, diarrhea, abdominal bloating, mild abdominal pain, or tenderness in the ovary areas. Severe symptoms include dark urine, decreased urinary frequency, shortness of breath, severe abdominal pain, rapid weight gain, tight or enlarged abdomen, or dizziness.
