I am considered overweight and on clomid. It was not suggested as an issue for commencement of clomid, however my weight was mentioned when we went for our first IVF appointment. Increased body fat (different to body mass) can alter the bodies responses to hormone stimulation and can also alter the development of follicles (possibly due to insulin resistance which can occur in PCOS but also in the overweight person).

Having PCOS can make the process of losing weight more of a challenge (to say the least ) but this process shouldn't prohibit you from being started on clomid. If your specialist does have concerns, get them to explain their reasons. That is your right as a consumer. Good luck!!
