Travelling when pregnant

The problems associated with arsenic in drinking water have been known for some time, but new research published in the BMJ helps quantify that risk with respect to cardiovascular disease. Yu Chen, New York University School of Medicine, joins us to discuss her research.

Also this week, requests for travel information for pregnant women are on the increase, but the available information is patchy. Lucy Chappell, a lecturer at Kings College London School of Medicine and one of the authors of a new clinical review on the subject, joins us in the studio to talk about the evidence and how to assess risk.
