Does BMI affect IVF success and should I lose weight first?
My BMI is 32. The clinic suggested losing weight before IVF. I am 36 and worried about delaying. What is balanced advice?
Short answer: Higher BMI can be associated with lower success and higher obstetric risks, and some centres have anaesthesia BMI limits for retrieval. At 36, aim for realistic improvements without indefinite delay—combine nutrition support with a time-bound treatment plan.
Answer #1
Why clinics discuss weight
Higher BMI links to higher gonadotropin needs, cycle cancellation risk in some studies, anaesthesia considerations, and later risks like gestational diabetes and hypertension. Even 5 to 10 percent weight loss can improve metabolic health for PCOS patients.

Answer #2
Avoid endless postponement at 36
Set a concrete nutrition plan with a dietitian for 6 to 12 weeks if safe, while completing workup and financial planning. If BMI policies block retrieval, ask about supervised programmes. Punitive delay without support is not good care; partnership is.
