Nausea After Egg Retrieval

Why Does Nausea Happen After Egg Retrieval?

30–40% of patients experience nausea after egg retrieval anaesthesia. Multiple factors combine:

The sedative drugs themselves: propofol and similar agents commonly trigger nausea and vomiting

Ovarian manipulation: the needle passes through the ovaries; thistriggers nausea reflex

Chemical changes: the procedure releases prostaglandins and inflammatory chemicals in the pelvis

Individual sensitivity: some people are naturally more prone to post-operative nausea

Timeline: How Long Does It Last?

Most nausea resolves within 1–3 hours of waking. Some patients feel fine immediately; others feel queasy for the full recovery period (2–4 hours). Vomiting, if it occurs, is usually just once or twice and stops quickly.Most patients are nausea-free on the same day. 

Medical Relief: Anti-Nausea Medication

Tell the anaesthetist you're prone to nausea BEFORE the procedure. Standard prevention includes:

Ondansetron : a 5-HT3 antagonist, given IV during retrieval; prevents nausea in ~70% of cases

Dexamethasone: a steroid given IV that reduces inflammatory nausea

If nausea develops despite prevention, ask for additional ondansetron in recovery

Natural Relief: What Works While You Recover

Ginger: ginger tea, ginger biscuits, or ginger supplements (active, not placebo)

Fresh air and rest: nausea often worsens with fatigue and poor ventilation

Sipping cold water: small frequent sips of ice-cold water often settles the stomach

Light, bland food: once nausea settles, small amounts of toast, crackers, or broth on the day of the procedure. The next day, you can have your usual healthy diet. 

Acupressure: applying pressure to the P6 point on the inner wrist (widely used in anaesthesia)

What NOT to Do

Don't eat a big meal immediately after waking; your stomach is irritated

Don't lie flat; keep your head elevated at 30+ degrees

Don't travel immediately; stay in recovery until stable

Red Flags: When Nausea Is a Problem

Nausea lasting >6 hours, vomiting >2–3 times, inability to keep fluids down, severe abdominal pain—these warrant immediate contact with your clinic. Most recover smoothly, but don't ignore persistent symptoms.

Q: Will nausea harm the eggs or embryos?

A: No. Nausea is a you-problem, not an egg-problem. Your eggs are safely in the lab being cared for by the embryologist.

Q: Can I prevent nausea with diet before the procedure?

A: Light diet the night before, fasting as instructed. No special pre-emptive diet prevents anaesthetic nausea, but staying hydrated helps.
