Professor Roger Gadsby, of Warwick Medical School, was the expert in demand this week as news broke that the Duchess of Cambridge was suffering with hyperemesis gravidarum. Roger, who published a study on the issue last year, was quoted in a number of national newspapers and appeared on BBC News and Sky News to discuss morning sickness in more depth. He summarised that pregnancy sickness is a “underappreciated and underresearched condition”, and pointed out that diclectin - an antihistamine and vitamin B6 combo – that is used to treat the condition quite well in the States, is not used in the UK in the same manner.
