Ovarian Hyperstimulation Syndrome (OHSS): Symptoms, Risks & Prevention

Ovarian Hyperstimulation Syndrome (OHSS) is a condition that can occur in some women undergoing fertility treatments, especially IVF. While most cases are mild and manageable, severe OHSS can be serious if not identified early.

Understanding OHSS—its causes, symptoms, and prevention—helps women feel informed and safe during fertility treatment.
At Nex IVF and Fertility Centre, patient safety and individualized care are always our top priorities.

What Is Ovarian Hyperstimulation Syndrome (OHSS)?

OHSS occurs when the ovaries over-respond to fertility medications used to stimulate egg development. As a result, the ovaries become enlarged and fluid may leak into the abdomen or chest.

This reaction is linked to hormonal changes—particularly high levels of estrogen and hCG.

⚠️ Why Does OHSS Occur?

OHSS is most commonly associated with:

Injectable fertility medications
IVF stimulation protocols
hCG trigger injections
High estrogen levels
Multiple developing follicles

It usually appears after ovulation induction or egg retrieval.

🔍 Who Is at Higher Risk of OHSS?

Some women have a higher likelihood of developing OHSS, including those with:

PCOS
Young age
High AMH levels
Large number of follicles
Previous history of OHSS
Rapid rise in estrogen levels

Identifying risk factors early allows doctors to adjust treatment safely.

🧪 Symptoms of Ovarian Hyperstimulation Syndrome

Mild to Moderate OHSS

Abdominal bloating
Mild abdominal pain
Nausea or vomiting
Weight gain
Enlarged ovaries

Severe OHSS (Medical Emergency)

Severe abdominal pain
Rapid weight gain (more than 2–3 kg in a few days)
Severe bloating
Difficulty breathing
Reduced urine output
Dizziness or weakness

Any severe symptom requires immediate medical attention.

🩺 How Is OHSS Diagnosed?

Doctors may use:

Clinical symptom assessment
Ultrasound to check ovarian size and fluid
Blood tests to monitor hormone levels
Weight and urine output monitoring

Early diagnosis helps prevent complications.

🛡️ How Is OHSS Treated?

Mild OHSS

Rest and hydration
Pain relief medications
Close monitoring
Avoid strenuous activity

Moderate to Severe OHSS

Hospital observation
IV fluids and electrolyte balance
Blood-thinning medication (to prevent clots)
Fluid drainage if required
Delay or freeze embryo transfer

Most cases resolve on their own with proper care.

🌱 Can OHSS Be Prevented?

Yes—modern fertility treatments focus strongly on prevention.

Preventive Measures Include:

Individualized stimulation protocols
Lower-dose fertility medications
GnRH agonist trigger instead of hCG
“Freeze-all” embryo strategy
Careful hormonal monitoring
Extra caution in PCOS patients

At Nex IVF, prevention is a key part of treatment planning.

👶 Can Pregnancy Occur After OHSS?

Yes.
Many women go on to have healthy pregnancies after recovering from OHSS. In fact, freezing embryos and transferring them in a later cycle often improves safety and success rates.

Proper recovery before pregnancy is essential.
