“Ovarian hyperstimulation syndrome”, also known as Ovarian Hyperstimulation Syndrome (OHSS), in the most basic way; It can be explained as a reaction to the hormones given to women for the development of the ovaries. During IVF treatment, women are given hormone drugs to stimulate and support egg development. When these hormone drugs stimulate the ovaries more than necessary, the syndrome of overstimulation of the ovaries occurs.
How Ovaries Stimulation Happens?
The aim of IVF treatment is to obtain a large number of follicles and eggs. The process of stimulating the ovaries is the stimulation of the ovaries (ovaries) of the expectant mother with drug supplementation. The aim of this process is to obtain a large number of eggs and thus to try to increase the chance of finding quality embryos suitable for transfer. The ovaries are stimulated by these drugs and when the ovulation period comes, healthier follicles are obtained. The mother-to-be, whose ovaries are stimulated by drug therapy, is followed by ultrasound and the maturation of the eggs is observed.
What is Ovarian Overstimulation Syndrome?
Ovarian hyperstimulation syndrome (OHSS) is an undesirable consequence of IVF treatment. Although the aim of IVF treatment is to develop a large number of eggs, OHSS may occur if more than a certain number of eggs develop.
Women with polycystic ovary syndrome are much more likely to have ovarian overstimulation syndrome. Excessive response to the drugs given to stimulate the ovaries prepares the ground for encountering this syndrome. During the stimulation of the ovaries, there is a fine line between stimulating the desired number of eggs and over-stimulating the ovaries. It is not always possible to determine this point clearly. When there is overstimulation, reducing the dose of ovarian stimulating drugs and not giving the drug for a day or more, if needed, can prevent the excessive rise of estrogen.
Symptoms of ovarian hyperstimulation syndrome can be mild, moderate or severe. These symptoms are;
-Increased ovarian size
- Abdominal pain, bloating, shortness of breath, decreased urination
-Fluid accumulation in the abdominal cavity
It can be seen as fluid collection in the chest cavity. It is extremely important to follow these situations closely and to get medical support when necessary.
How is Ovarian Overstimulation Syndrome Treated?
OHSS treatment is carried out to relieve the expectant mother, reduce ovarian activity and prevent complications. However, OHSS can be performed in two different ways as drug and surgical treatment. In mild cases, no additional treatment is required other than outpatient follow-up and severe physical activity restriction, and the patient can usually recover in 10-14 days. Moderate and severe cases may require hospitalization and treatment. In most cases, women who have had OHSS can continue IVF. It is still possible to become pregnant despite OHSS, but these symptoms may worsen if pregnancy occurs. In this case, the patient is followed closely under the supervision of a doctor.
