Weight loss surgery and fertility

I had the pleasure of presenting some evidence for weight loss surgery to the British Fertility Society Meeting in Sheffield on 8th January 2014. There is evidence that weight loss surgery may improve female fertility in patients with ‘morbid’ obesity (BMI >= 35) and lead to an increase in the chance of pregnancy afterwards. Pregnancy itself should be avoided in patients 12-18  months after undergoing weight loss surgery and contraception should be carefully considered by patients undergoing a bariatric procedure. A number of pregnancy outcomes are improved after weight loss surgery.
